Services
Boundary Surveys
Our boundary surveys precisely define property lines using historical records and modern GPS technology. We resolve disputes through accurate measurements and documentation. Clients receive detailed maps and explanations of corner markers.
Elevation Certificates
We create FEMA-compliant elevation certificates to determine flood risk and insurance requirements. Our surveys document building elevations relative to flood zones using certified measurement techniques. Results help clients potentially reduce insurance costs.
Underground Utility Locating
Using ground-penetrating radar and GPS, we locate subsurface utilities under our AAB Utility Locating division. Our surveys identify water, sewer, and electrical lines to prevent damage during construction projects.
Mortgage Loan Inspections
We perform mortgage loan inspections to verify property compliance with lending requirements. Our services include flood zone determination, setback verification, and providing documentation directly to loan processors for closing.
Topographic Surveys
Our topographic surveys map natural and man-made features with elevation data. This information supports construction planning, drainage analysis, and land development projects across residential and commercial properties.

Jun 26, 2024 Report
I reached out to five highly reputable surveying professionals for proposals, and Nadeau stood out from the start. They had the quickest response time, the most efficient turnaround, excellent communication, and the best price. Most importantly, the results were fantastic. Professional boundary surveys are more expensive than many people realize, but in my case, the investment was absolutely worth it. I learned more about my property than I ever could have imagined, and I couldnt be happier with the service I received.

Asked Jim for a quote to help identify existing property pins or find where they should be for the purposes of installing a fence on the property line. I have a 12,000 square foot lot. I was given a quote for over $4k. I asked for some explanation as I've had other surveys done on much larger and more complex properties for only a few hundred dollars. Unfortunately I did not get any reasonable effort to help me understand why the quote was so much or any willingness to reduce price. Seems like an insane price for what I'm looking for as a homeowner looking to install a fence. Would not recommend.
