"The team that was sent smelled of weed, first thing I noticed. The work was done quickly, so that was good, but they didn't get an in process inspection and instead sent over an inspector more than a month after the work was done. The dirt that was displaced is just all over my yard now, and I have a bunch of big holes where they didn't pack any dirt. The company offered to fill them but I never heard back after that offer. As part of the work, they dug around the chimney, and it appears they caused it to break. They claim no damage was done, but I'm finding many pieces of concrete and brick strewn over my yard."

"These guys were amazing from start to finish. The communication from beginning to end was exceptional. Joe arrived on the date agreed and was very punctual, He first explained very clearly the process that he was using and how effective it would be in preventing water from entering my basement through this crack in the foundation. He then proceeded with his work and did so quickly and efficiently leaving no mess behind. I am thoroughly impressed with A-1 and wholeheartedly and highly recommend their high quality services. Plus, with their 10 year warranty, you can rest comfortably. Without doubt, these guys are A1."

"Paul did an awesome job repairing my Victorian step cap chimneys. Communicated clearly, arrived when he said he would and left the job site clean. Price was very reasonable. I read the review from Mike O. and asked him about it. Apparently, there is another company with the same name in the Portland, Maine area and that review refers to that company. Will definately have him back to do more work on my stone foundation."

FAQs for basement drainage channels installation projects in Dover, NH

Expect a well-built French drain to last 30 to 40 years. By channeling both surface- and ground-water away from your foundation, the system relieves hydrostatic pressure and helps prevent costly structural damage. Choose a pipe with a quality cloth filter to keep sediment out and extend the drain’s life. A quick annual inspection and routine cleanouts will keep water flowing freely, ensuring the system continues to protect your home for years to come.

Most French drains sit two feet below grade, but depth ultimately depends on the problem you’re solving. For puddling rainwater or snowmelt, a shallow curtain drain at lawn level often does the trick. To handle rising groundwater, pros dig deeper, down to the footing, and run the pipe beneath the basement slab. A drainage contractor will determine the optimal depth for your specific soil conditions and water issues.

A properly installed interior French drain captures water at the slab, channels it to a sump pit, and directs it safely outside, preventing basement floods before they occur. Because the pipe sits just under the floor edge, a plumber can reach it easily for cleaning or repairs. Pairing the drain with a reliable sump pump gives you the best long-term protection.

Hire a contractor who installs drainage systems every day—typically a foundation specialist, drainage contractor, experienced landscaper, or plumber with waterproofing experience. These pros understand slope, soil, and local codes, and they have the equipment to trench safely around utilities. Ask for references and photos of recent jobs to be sure they can design a system that keeps water off your foundation for decades.

Once the drain is in, patch the yard by reseeding bare spots or replacing plants the crew removed. Inside, look for ways to add value—finishing the basement or upgrading interior waterproofing while the space is open often costs less now than later. Schedule a quick annual checkup to flush sediment and confirm the pipe and sump pump are clear. Consistent maintenance ensures the drain functions properly and protects your investment.

Most policies don’t cover the cost of repairing a French drain itself, but they may provide coverage for water damage if the system fails. Coverage varies by insurer, so be sure to read the fine print or contact your agent before any issues arise. If you live in a high-risk flood zone, consider a separate flood policy to close the gap. Knowing your coverage in advance helps you budget for repairs and avoid unexpected costs.
