Some of our most loyal clients are homebuilders, realtors, and attorneys working with homebuyers. We work closely with the homebuilder siting the house sited for construction and insuring the home is placed properly on the lot. We prepare mortgage plats at the request of attorneys, realtors, banks, and title insurance companies. These plats are used in closing loans for homes and land.

We have a wide array of experience and expertise, and will always provide these qualities to our clients.

We currently use the most updated equipment available. All of our crews are equipped with total stations, levels, and all of the accessories needed for conventional surveying. In addition, one crew uses a robotic total station, which requires no instrument operator.

  • I would not recommend this business
  • That company like to move the old point

This company loves to move the old points that are for years and if you give it more money on top. put everything in your favor. and because of the surveyors' law book they cannot move any point and before doing so they have to stop and write to the state to indicate what happens to make them move it since there is part of the city so well wrapped sorry but I would not recommend them to look for a company of class A and that this in 5 and more not 3.7 like this company thanks

Customer Testimonials

To whom it may concern, I have been using Marsh & Long Surveying, Inc. since 1996 as a real estate attorney and also as a real estate developer. They have performed work for me all aspects of land surveying, including real estate law, property line dispute resolution, right of way and easement work and many other areas of law. In the development area, wetland surveys, plans and submissions, subdivisions and residential and commercial developments of various sizes are the typical projects they have performed for me. The survey crews employed at Marsh & Long Surveying, Inc. are highly experienced, qualified, competent and very professional to work with.

I find Marsh & Long Surveying, Inc. to be extremely responsive to all my land surveying needs. Their work is precise, completed on time and is of the highest quality. This high quality of work makes my job as both a real estate attorney and also as a developer much easier and professional when representing clients or presenting agency submissions.

I have repeatedly recommended this company to clients, family and friends and do so again here.

I have been developing projects and working with Marsh & Long Surveying, Inc. for the two past decades on multiple small, medium and large scale projects. These projects have ranged from a Marriot Hotel/gas station complex, multi building office parks, residential subdivisions and an office condominium project. Marsh & Long Surveying, Inc. has provided all the property line and topographic surveying as well as wetland location and finished mapping for agency submissions. My largest problem with surveying firms had always been with the coordination, scheduling and turnaround time on projects. Marsh & Long Surveying, Inc. has always completed work within contracted dates and allowed me to meet these strict submission deadlines.

This firm provides service that is at a level far and above what I have previously experienced. They are extremely flexible in their scheduling and turn my projects around in a timely fashion. In particular, the firm's presentation of materials and attention to detail are second to none. Our projects have been getting approved and are being completed on time.
I strongly recommend Marsh & Long Surveying, Inc. for your project.
