What Customers Say About Us:

Betzi Calle, Darien, said: Monday, January 13, 2020

Great experience. Gregory responded to my inquiry almost immediately. He did an amazing job, staking and marking my property lines clearly and helping me with the building permit process, he is very professional, knowledgeable and went beyond what I asked him to do. I highly recommend Advanced Surveying, LLC. Thank you very much. 

Andres Galeno, Greenwich, said: December 1,2019 6:45 PM

It was a great experience working with Advanced Surveying LLC. I dealt with Greg, the owner, throughout the surveying phases needed and it was delightful dealing with him. Greg was very professional in all aspects from scheduling, submission timeline, and coordination. He went above and beyond explaining the process and experience he's had with similar work, and with the Town of Greenwich where the service was provided. I would work with Advanced Surveying again in the future and highly recommend this company if there is any surveying work needed. With excellent professionalism, fair pricing, and quality work what else can you ask for. 

Lisa D'Alton, Stamford, said; August 28,2019 8:31 PM

A total professional. Responded quickly to my inquiry and presented a fair quote. Educated me as to what his process entailed and kept me informed as he progressed. Completed the job as requested. Would definitely use him again.

Gregory is your entrusted defender and will ‘have your back’, as you travel the process with him in discovering where your property borders actually lie. I needed a proper land survey done on a particular electrical ‘easement’ on my property that abutted a neighbor’s. There had been significant large pine tree damage after this past winter that impacted three neighbors and none of us had a clear idea where our property lines were located. After contacting Gregory, who responded immediately in an extremely professional manner, we walked the property together and he explained in a detailed way what our goal should be, how long it would take and what documents were necessary to complete the ‘search’ with the City of Stamford. His estimate of the work entailed was very reasonable and I was relieved to share with him my concerns going forward. Every step of the way was explained to me and there were no surprises due to his thorough teaching. The work was completed in a timely fashion, one that I could afford and I learned a lot about surveying along the way. I highly recommend Gregory’s services for any type of surveying needs and if you check out his websites, you’ll be impressed with the ease of navigating them for any of your concerns. He is courteous always and respectful of my time/schedule and inane questions, while being prompt in corresponding quickly to any of my emails. I will not hesitate to call Gregory in the future for any surveying needs I might encounter.

Brittany C. said:   April 6th, 2018 9:16 pm

Gregory did a great job with surveying our property. He responded to my inquiry incredibly quick and that remained the same throughout the whole process. He was very thorough and answered all the questions we had along the way. Would highly recommend.

Ali C. said:   September 20th, 2017 1:11 pm

I highly recommend Gregory for any survey needs. He was incredibly quick to respond to my inquiry, and he completed the entire project before any of the other 5 companies I reached out to responded. He was highly informative, very friendly, and extremely easy to work with. He even went out of his way to answer additional (slightly unrelated) questions I had after the project was completed with the same speed and helpfulness. Thank you!!

Lindsay S said:   November 15th, 2016 9:44 am

Gregory was prompt, responsive, and thorough from beginning to end on our project. I do not hesitate to recommend him for any of your surveying needs.

Michael Mastrogiacomo said:   October 11th, 2016 9:20 am

Gregory is very personable, honest and professional. He executed the land survey on time and explained the process throughout. He understands the permit process with the City of Stamford . In my case he worked with watershed areas and wetlands. on a wooded lot set back from the street. Not an easy job. I would recommend Gregory , no doubts, to anyone requiring surveying work.

Jim Taubner said:   August 4th, 2016 3:18 pm

We were very happy with the work and Gregory made the whole process very easy. He is very professional and explained everything each step of the way. 

Jerry F. said:   July 25th, 2016 9:49 am

Gregory is prompt, professional and a pleasure to work with. I would sincerely recommend him without exception.

G. Parr said:   July 12th, 2016 2:13 pm

Professional, Professional, Professional. That's what you receive when you hire Gregory. I contacted Gregory about a year ago for a quote in which he responded immediately. We put the project on hold and came back to Gregory this past May and again the response was immediate. Very detailed and thorough. A pleasure to work with and I would highly recommend his services to anyone.

Joe Gottschalk said:   May 6th, 2016 1:59 pm

Gregory is a true professional. When I initially contacted him, I got a reply right away. Gregory explained all necessary steps and carried out the survey to our full satisfaction. He also responded immediately to any questions I had afterwards. It was a pleasure to work with Gregory and I recommend him to anyone that needs a land survey. 

Chris Galakoutis said:   May 3rd, 2016 3:01 pm

Greg is a true professional and a pleasure to work with, explains what he is doing in detail and is always prompt. I would not  hesitate to recommend his services. 

J. Burke said:   January 8th, 2016 4:46 pm

After I spoke with Gregory about an engagement I called some other surveyors to compare. When speaking with someone in a related discipline he, without prompting, endorsed Gregory. And so I decided to work with Gregory on a land surveying and survey map. He was timely, professional and very thorough. I am completely satisfied with the experience. I can't recommend him in strong enough terms. I will suggest him to others and contact him again should the need arise.

Tony C. said:   December 12th, 2015 3:26 pm

Gregory has done work on my property twice in the past few years. He is always polite, professional and thorough. What I appreciate the most, aside form his work ethic, is how quickly he replies to you. Thank you Gregory for all the work you've done for me. 

Donna Bruner said:   July 26th, 2015 3:40 am

Gregory was a pleasure to work with. He worked quickly and efficiently. I highly recommend him. 

Roberto Ucero said:   July 21st, 2015 6:58 am

Highly recommend Greg, His delivery was timely and professional, Had to contact him for additional information months after the project and very promptly replied with the needed assistance.

Bob Coleman said:   June 28th, 2015 4:11 pm

Gregory.. Went beyond our scoop of work expectations and delivered a highly professional result in a timely fashion. A real pleasure to work with. Highly recommend him.

Kenneth Mccoy said:   May 4th, 2015 10:40 am

Greg is a professional. Really easy to work with. Delivered plan as scheduled. I have already recommended him to other friends. 

Mark Spergel said:   March 30th, 2015 7:29 am

Gregory was a consummate professional. Always prompt, responsive, and thorough. He did an expert job for us and provided helpful advice that went above and beyond what was required. You don't come across this level of service much these days. Picking someone from an Internet search is always a stab in the dark, but with Gregory we really got lucky and feel like we have a working relationship we can draw on in the future. I recommend him enthusiastically nd without reservation.

James said:   March 3rd, 2015 5:11 pm

Greg was wonderful to work with. Unlike the long waits and scheduling challenges with some of the larger firms, Greg was responsive, timeline and a contributor to the completion of our project "on time" (which is difficult to accomplish in construction). We highly recommend him!

Andrea & Chris GIlbert said:   December 24th, 2014 11:43 pm

We are so glad that we found Greg. His work is excellent, he was very thorough, and he made a point to explain every step of the process to us from start to finish. He was also very easy to get ahold of (something that we struggled with in communications with other land survey teams) and prompt to return our calls/emails. We couldn't recommend him more highly! He is fantastic!

Marisa Z. said:   November 5th, 2014 10:07 am

Gregory was very easy to work with and professional. He responded within hours to any inquiries and turned around the work very quickly. Most importantly he was very careful to be accurate, which was very important to us working on a small lot with strict boundaries. He knew all of the zoning regulations and the Westport zoning officer we met with was familiar with him and said he did "very good work". Zoning requested no changes to his survey. I would recommend his work without hesitation and use him again myself in the future. He makes the time to get your project completed and turns out a high quality survey at a very good price.

Jeanine Gutauskas said:   November 5th, 2014 7:31 am

Greg recently finished a project for me. He returned my initial call the same day and completed the project within days. He was prompt and professional. I highly recommend him. 

Bob Hurwitz said:   October 3rd, 2014 1:46 pm

I was given Greg's name from a friend who had used Advanced Surveying and had spoken highly of Greg and his company. I used Advanced Surveying for a difficult elevation, wetlands and plot surveying project. Greg did a great job, he explained everything that I would need and why I needed it. He worked with my septic company and architect and his professionalism and industry knowledge is impressive. I strongly recommend using Advanced Surveying and would use them again should the need arise.

Tom said:   September 29th, 2014 8:05 am

Without much knowledge about getting a survey done, we chose Greg and his team. They did an excellent job in a very timely fashion. Extremely thorough and a pleasure to work with. Thanks again

Bill Douglass said:   August 25th, 2014 3:05 pm

Excellent, top-notch work. Very professional and thorough.

Boguslaw Kowalczyk said:   August 13th, 2014 10:10 pm

Gregory did excellent job surveying and staking out the property. It wasn't easy task since no adjacent property was ever surveyed. But even with these issues Gregory was able to deliver as promised, addressed all our concerns. He is very professional and I will recommend him to all in need of these kind of services. 

Todd said:   August 11th, 2014 11:22 am

Gregory was prompt and professional about our elevation certificate.Also at a good price. I will be recommending him to anyone who asks.

Tim McNeill said:   April 29th, 2014 7:55 am

Gregory responded to our call quickly, and got the job done ahead so schedule at a good price. I recommend him.

Tom said:   April 23rd, 2014 9:03 am

Gregory did an excellent job surveying our property with very limited information and no existing survey to go by. He went over and beyond the scope of his work to make sure he delivers what we needed. I'm very impressed with Gregory's work ethic and flawless communication process. Definitely will recommend him to anyone who needs the job done right and timely. Best surveyor in the area by far.

James from Stamford said:   April 22nd, 2014 9:52 am

Gregory was prompt and professional about our elevation certificate. I will be recommending him to anyone who asks.

Tom said:   January 27th, 2014 9:58 am

Gregory was great and completed my job early. I would definitely recommend him to anyone.

Tony from Stamford said:   January 18th, 2014 9:38 am

I like to take my time when selecting anyone to do work on my property. From the moment I made contact with Gregory, he has been nothing but professional. Not only is he knowledgeable, friendly, and easily accessible, but he is sincere with looking out for your best interest. I felt very comfortable with Gregory and highly recommend him. 

John said:   December 15th, 2013 4:19 pm

Gregory provided timely service and good work - a very detailed survey. He would always return my emails or calls within a few hours. He is more than willing to incorporate changes to make sure the client is satisfied with the end product. Definitely would recommend. 

Sarah from Darien said:   October 21st, 2013 8:26 pm

Not only did Gregory do a great job (at a good price and in a timely manner) of surveying our property, he took the time to thoroughly answer some questions we had two years later! The sign of a respectable professional. We would defintely recommend his services.

Calvin from Stamford said:   October 20th, 2013 8:07 pm

Gregory was extremely professional and well prepared. He actually completed my job a week in advance. I would definitely recommend.

Krista said:   September 12th, 2013 5:37 am

Gregory Kogan demonstrated a conscientious patience along with an exceptional professional skill and communication. He is good to his word and very accommodating to personal need. He is in my network of contractors to refer on to future clients.


Jim from Westport said:   August 20th, 2013 10:25 am

I called several local Land Surveyors and had to chase them down, always hearing "...maybe 6 weeks out". Gregory returned my call and started our job immediately. His work is excellent, he is easy to contact, and he explained very step of the process clearly. Great job, great price.

Dennis said:   July 13th, 2013 9:09 am

I concur with others on this site, Gregory was extremely responsive, professional and thorough. The process was non-intrusive and the results exceeded my expectations. I would recommend Advanced Surveying, LLC and Gregory to anyone and everyone

Keith said:   June 26th, 2013 8:33 pm

Gregory is extremely professional, greatly educated and an expert in his field. He was able to meticulously survey a very difficult property with almost every possible obstacle in his way and do the job perfectly, on time and on budget. His thorough communication throughout the process was of great help and I very highly recommend his services without hesitation.

Deb said:   June 20th, 2013 8:58 pm

We are satisfied with his work. Would recommend him.

Tonia Campbell said:   June 2nd, 2013 12:22 pm

Love the work provided. I will recommend to anyone. Very professional and do excellent work as promised 

Dave from Stamford said:   May 17th, 2013 5:59 am

I had our property surveyed and staked by Gregory. He did an outstanding job and explained each step. He answered emails and phone calls promptly and his prices are unbeatable. Quality job, friendly service, great price !

Michelle and Charlie said:   May 14th, 2013 8:35 am

Greg was outstanding. He arrived first thing in the morning and worked diligently until the job was finished. We couldn't be more pleased. I highly recommend Greg to anyone. If you want the job done right, call Greg. A+++

Kev said:   April 9th, 2013 10:51 am

Greg was great. Friendly, thorough and professional. Highly recommended

Maggie & John said:   February 26th, 2013 7:57 pm

We are so happy we found Greg to survey and stake our property. He was extremely knowledgeable and took the time to explain everything to us. Always responded quickly, we were never left waiting. We HIGHLY recommend Greg. Thank you again Greg! It was a pleasure working with you! 

Nancy & Curtis Troeger said:   February 7th, 2013 3:32 pm

Gregory is a rare find: Professional, honest, prompt (responded w/in hours of every question/request), recommended other professionals who turned out to be great, and completed the job quickly. He also went above and beyond his job helping us out by speaking to our Town Hall representatives and getting questions answered. I highly recommend Gregory.

Chris Brugo said:   January 29th, 2013 6:43 am

I was very impressed with Greg's work. He produced a very good product in a very tight time frame. I would recommend Greg to others without hesitation.

Scott said:   November 18th, 2012 8:56 am

Great job. We had a fence come down from the big Sandy storm, but being relatively new to our home, we didn't know exactly where the property line was to replace it properly. Gregory was able to help us out fairly quickly, getting appropriate areas properly staked out. He was also very knowledgeable about town procedures, zoning needs, etc. They were incredibly through in double-checking sub-division areas and locating pre-existing lines / markers we had no idea where there. Definitely recommend.

Agnieszka S. said:   November 12th, 2012 10:07 pm

I was very satisfied with the service Gregory provided. He was quick and did an excellent job. I would definitely recommend him to anyone who needs a survey.

Mariola said:   November 9th, 2012 2:02 pm

Greg from Advanced Surveying did an excellent job on staking and mapping our property in New Canaan. He promptly responded to our request and within few days the job was done. Very professional and thorough, I would highly recommend his service.

Bari said:   September 18th, 2012 9:11 pm

Gregory was very professional and responsible in the entire process of staking and mapping our property in Fairfield. From the moment we hired him I knew we made the right decision. He explained the entire process to me and answered all of my questions in a very comprehensible way. He responded to emails and completed the work faster than I could have hoped, and he did an incredibly thorough job! When an issue arose with our neighbor he was as helpful as possible in dealing with the individual and providing us with the information we need to proceed. I highly recommend Advanced Surveying.

Emily said:   August 7th, 2012 8:24 pm

I was very happy with the surveying job Gregory did for us. It was done rather quickly and was very complete. He found a property line issue and took the time to explain everything to me. I would recommend him to others. 

Jen B. said:   July 30th, 2012 7:58 am

I found Greg on Angie's List and was extremely impressed with his work. He staked the property lines for our new house in Fairfield. He responded almost immediately to all emails and got the actual staking done in a day or two from when I contacted him. He explained each step in the process to me and his quote was exactly what he invoiced me for. We were afraid we'd have to get a full survey to find out our property lines (to build a fence), but Greg suggested staking the property - which let us know our boundaries but also saved us money. He was just a really professional guy and a pleasure to work with.

Rob said:   July 23rd, 2012 12:13 pm

Arrives on time, completed work ahead of schedule, very fair pricing and great to deal with, THANKS!!

Kenny R said:   June 23rd, 2012 6:07 pm

Gregory and his team just finished the survey of our new home in Wilton. Nothing but pure professionalism and on time delivery for the task at hand! Answered all my questions and was available virtually anytime I needed to speak with him!

M.m. said:   June 18th, 2012 8:58 pm

Gregory Kogen was extremely responsive, accurate, honest and fairly priced. Advanced Survey has earned its way onto my short list of reliable companies that I would recommend without hesitation. Hire Gregory with confidence and anticipate AAA service and quality. 

Kevin said:   June 7th, 2012 2:10 pm

I had the opportunity to work with Gregory Kogen when he surveyed our new home. He could not have been more helpful guiding us through this process as we were first time homeowners. He answers emails immediately and was always available by phone. Gregory's quote was easily the best of three we received. He was able to accommodate us very quickly and was at the house in one/two days after we went with him and completed the project in 3/4 days with a very descriptive walk through of all the set backs, town codes,and variances we may need for additions. I would not hesitate using his services again.

D.B. said:   June 5th, 2012 8:53 pm

Advanced Surveying is by far the most qualified and professional surveying company in Fairfield Country. Advanced Surveying returns calls promptly; Advanced Surveying starts and finish work AHEAD of schedule. It is a company that over-delivers every step of the way.

C. Zerilli said:   June 4th, 2012 9:58 pm

We had an excellent experience with Advance Surveying. Gregory and his team do a very thorough job with outstanding follow through. Everything listed in the proposal was completed swiftly, as quoted. Would have no reservations recommending him to friends or family. 

J. O. said:   May 21st, 2012 10:54 am

We were very impressed with the service from Advance Surveying and would highly recommend them. They answered our call promptly, surveyed our property within days and gave us a reasonable price for the job. Very thorough, very fair price. Would use them again. Thanks Greg!

E.S. said:   April 23rd, 2012 10:46 am

I needed a Survey and stake out property lines for the house I purchased late last year. I found Advanced Surveying on Gregory responded immediately . The project was completed in less time than anticipated and was exactly what I was looking for. For excellent customer service, accurate and detailed work and a great price, Advanced Surveying is the place to call. Highly recommended.

Brian F said:   April 17th, 2012 1:30 pm

We were very impressed with the service from Advance Surveying and would highly recommend them. They answered our call promptly, surveyed our property within days and gave us a reasonable price for the job. They did a lot of homework locating subdivision monuments, stakes and markers to ensure their survey was as accurate as possible. We are confident in their work as much as they are! Without hesitation we would use them again for any surveying needs. Thanks again Greg for your hard work-Brian

S. Chin said:   April 9th, 2012 3:38 pm

We wanted to do a Survey and stake out property lines for the house we purchased last year in order to set boundaries for plantings. We found Advanced Surveying through ServiceMaster. Greg responded immediately and more importantly kept responding to our questions on a timely basis. The project was done on time and well, exactly as he discribed. Highly recommended.

Sasa Mahr-batuz said:   April 9th, 2012 12:13 pm

it was a pleasure to work with all got done fast, very professional and well priced would most definitely recommend Advanced Surveying LLC

Sweta said:   April 6th, 2012 8:42 pm

Thoroughly appreciate the survey work Gregory did for us on our fencing project. He guided us through the process (which he didn't have to) and was prompt in answering all questions we had, before, during and after the project. We would highly recommend him for anyone looking for a surveyor.

Doug & Rose said:   February 21st, 2012 9:29 pm

We recently purchased a home in Weston Ct which Gregory of Advanced Surveying performed the survey. His attention to detail is exquisite, correspondences were always prompt, he took the time to explain topics in detail and the survey map was beautiful. Even the local building inspector commented on the details of the survey. I would defiantly recommend Advanced Surveying and will be using them again in the future.


Arvind Chandramohan said:   February 20th, 2012 3:36 pm

Gregory did a meticulous work and at a reasonable price. I would recommend him anytime.

Dan Magee said:   February 5th, 2012 12:57 pm

We hired Gregory to stake out our property lines in preparation for some new landscaping plans and to clearly define our neighbor's encroaching driveway... We contacted several surveyors in the are and Gregory was the only one to respond in a timely manner and with a very fair quote. He was meticulous in his detail of mapping out the neighborhood markers to make sure to accurately locate our own property lines. The encroaching neighbor was very unhappy we were staking our lines and gave Gregory a very hard time while he was working on our property. Greg was extremely patient with the neighbor and took extra time explain the process to avoid more confrontation... We would not hesitate to hire him again or to recommend him to friends and neighbors. He went above and beyond our expectations.

Sarah Hu said:   January 29th, 2012 5:42 pm

Greg did the great job providing the surveying service to our newly purchase home. They worked very hard even in a snow weather. Their price is reasonable as well. I would not hesitate to recommend their service to anyone.

Brian and Amy V. said:   January 25th, 2012 8:13 pm

After moving into the area, we wanted a survey of our lot to know what is ours to maintain, and to know where the setback lines are. We hired Advanced Surveying to map out our parcel and stake the property lines, and are very pleased with the results delivered by Gregory. He explained the process well and was very thorough. We definitely recommend him.

A minute saved is a minute earned, and this saved hours!

Yury Feygin said:   January 15th, 2012 9:52 pm

We hired Advanced Surveying, LLC to perform a survey for our property in Stamford in the winter of 2010. A very professional service team was timely and informative, helping us determine where our property lines were, and even discovering facts we did not suspect were possible. As a result, we found that our neighbors fence was on our property, encroaching over 20 feet. The surveying team also helped us contact the town, advised us of wetlands on our property and recommended a soil scientist. A clear and easy to read, informative, detailed report was put together within days and we are confident in the accuracy of the data. Our field representative, Gregory, was very knowledgeable and spent extra time educating us about our future building plans and rights as property owners. We highly recommend this company and will definitely use them in the future. 

Dominique M. said:   January 12th, 2012 10:53 am

I asked Advanced Surveying LLC to do a boundaries survey. Gregory did a very good job, quickly and went the extra length to be sure all my questions where answered. The price was very reasonable compared to others, his job was very clean, precise and detailed. I will use him again next time I need some land survey. Thanks a lot and keep up the good work.
