"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results. <br />"

"Wet Basement Solutions sealed the walls of our basement and installed a sump pump about three years ago. As of today, 5/2/23, our area has experienced a great deal of rain, which would have caused our basement to flood in previous years. Since WBS did their work for us, our basement has remained perfectly dry. My husband and I have been singing their praises for the last few days!"

"Our backyard was a disaster: an old splintering deck, a large portion of unusable space due to a sloped lawn, drainage issues and a retaining wall that needed replacement. <br /> We went with Key Landscaping per recommendations from trusted sources. Our yard was a big job and big investment but Key was definitely the right company to use. The level of quality and professionalism with which they tackled the job was extremely impressive. It's rare you find companies who take as much pride in the quality of their work as Key did. They weren't satisfied until we were and approached everything always with an eye towards excellence. They also brought useful suggestions to our project as to moving existing plants and bushes therefore saving us money in the process. Our yard has gone from an unusable and dangerous space, to a kid-friendly, outdoor living space complete with beautiful patio, fire pit and waterfall. Calls and texts were returned promptly and workers showed up when expected. Everyone involved with Key was friendly and knowledgable. Highly recommend this company to any one in our region looking for landscapers with integrity. <br />"

"I had the company that put our basement water-proofing system (not VT Concrete) in and they came out promptly and charged to actually do nothing.  They recommended the Santa Fe dehumidifier at a cost of $2400.  Checking online I found that Roy's company charged $1700 and would install it for free.  He was prompt, knowledgeable and showed us what the other company should have done.  The other company kept wanting to sell us things and kept mentioning work they could do.  Roy was helpful in educating us about the system (we bought the house after it was put in).  They also confirmed what we thought, that the other company put the drainage system so close to the house that the water was actually just being recycled into it!  I will have them do our follow-up yearly system check.  <br />"

FAQs for basement drainage channels installation projects in Keene, 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.
