"Mixed review I had spoken with other radon remediation companies and received quotes before meeting with Erickson Foundation Solutions. The salesman, Chris, seemed much more thorough in his approach and he gave a presentation explaining radon, its danger and the process to remove it. The quote was slightly higher than another quote, but I felt more confident. And with the added fan moisture guard, the system came with a 10-year warranty. So I agreed to the proposed plan and paid a deposit. Later I decided to not install concrete in the adjacent (but not connected) basement/crawl space. I asked Erickson to quote installation of plastic sheeting to seal that space. John, the sales manager’s quote doubled the total price. I already had found durable plastic sheeting for about $300. So how would that become $2000 extra? John explained that there would be a drainage mat under the plastic and it would be attached every few inches to the walls and then sealed with caulking. But besides sealing the area, the quote also included another extraction hole and piping to connect it to the fan. This seemed to me like over-kill for a 1200 square-foot house. But he said without the second extraction location, they would not warranty the job. So I accepted the “up-sell” and signed. Today the office called to tell me when the crew would arrive and they arrived on time and were very pleasant. However, they did not have the drainage mat. They called their supervisor and was told that it was not included in the quote and would be an additional charge. In fact it had been a verbal inclusion, not written. The crew was surprised that a second extraction hole was quoted, since the radon levels were not very high to start (3.8 and 5.4). So I feel that I accepted a possibly unnecessarily elaborate system, more elaborate than I probably really need, for twice the price. And didn’t receive the drainage mat that I was told would be part of it."

"Owner Eric - Extremely responsive! Very reasonable quote to gather and take leaves away! And boy did his crew of two men do just that. They blew it out, working like there were 4 of them - in the pouring rain no less!!! And super meticulous. You cannot ask more from such a company -- I 100% recommend them with two thumbs up."

FAQs for basement drainage channels installation projects in Northwood, 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.
