R&M really helped me out to fix my septic system to complete a real estate deal. Excellent work and fair pricing. Can't recommend enough.
Kaleigh Vukobrat
We hired Colton to install a sump pump in our basement and are very pleased with the work performed. Due to our drainage and flooding problems (and indecisiveness!), Colton came to our property a number of times to assess the situation, do some camera work and provide quotes. He was transparent, always prompt with communication, and the quote contained thorough detail explaining each step involved. The sump pump was installed in 2 days by Colton and Wyatt and we are very pleased with the work performed. Would highly recommend.

I highly recommend R&M Coastal Contractors for your excavation work.
Colton, Scott and the crew were tasked with preparing our driveway for new asphalt, replacing the water supply pipe and adding 100 feet of drainage to our yard. They needed to tear out the old driveway, dig trenches, and attach existing house drainage.
The team certainly accomplished this project in an exceptional manner as they are all conscientious workers and there were no unnecessary work stoppages. All issues were dealt with professionally and promptly.
The guys communicated often to both my wife and I in a respectful, straightforward manner. We were always aware how the project was progressing.
The price was fair and we had no surprises. R&M would be our choice for future excavation projects.
Andrew Colmer
The team at R and M did a fantastic job on our drainage. We have an old house and were concerned about the drain tile. They took the time to explain everything that they were doing. They even went so far to help us move some trees so they were not damaged during the excavation. They kept the site clean and safe during the project. They finished on time and on budget. We have recommended R and M on many occasions and will continue to do so.
