"The entire experience was professional and of high quality. Jason came out to my home and provided an estimate for installing an internal french drain around the perimeter of my entire basement. The price was the lowest of three contractors by a wide margin. The team came out and completed the entire job in three days. My home was left cleaner than it was before and no debris was left behind. They even agreed to fix a small issue, not their fault, without an extra charge. I highly recommend AA Action Waterproofing and would hire them again."

"Dan Kelly is honest and will address any issues in the system. We had flooding due to poor drainage. Dan helped design a system to divert the water around and further away from our finished basement. When the system was overwhelmed in heavy downpour, they came back out twice to make necessary changes to keep all the water out of the basement."

"The staff of Drainage and Erosion Solutions is great! They called me the day before the appointment to confirm it, which other companies do not do often. In addition, on the day of the appointment, Rob R. called me to let me know that he was on his way. I really like that the staff of this company is so responsive and professional! When Rob R. arrived for the appointment, he looked at the side yard where there is soil erosion, and he listened to me while I explained the issue in detail. Rob R. determined that the solution to the soil erosion problem was simple landscaping, and my husband and I can do it in a weekend with some landscaping supplies. He gave me a free detailed recommendation related to the solution, which was above and beyond my expectations! Rob R. is truly an honest and knowledgeable professional! We didn't need to hire the company, but we will definitely hire them if we need any professional help with a wet yard or a wet basement! I strongly recommend Drainage and Erosion Solutions and Rob R.!"

"We found Basement Waterproofing Nationwide to be highly ethical and very knowledgeable. A little over a year ago we had BWN perform some basement waterproofing. We were delighted with the work and the options presented to us as well as the speed with which it was done. This summer during the very heavy rains, we had some water seep into the basement so we called for an evaluation. As it turned out, the rebuild contractors (which we had opted to contract with a lower price provider vs. using subs hired by BWN) never communicated to us that the newly installed sump pump required an electrician and that it was not hooked up. This house is inhabited by tenants and we are not in the same state, so it's hard to tell where the communication breakdown occurred. Basement Waterproofing Nationwide's service rep however was extremely professional and helpful in delivering this bad news. He also checked and was able to confirm that the waterproofing was still good. He made a few suggestions like letting us know that he noticed where the drywall had been replaced that the outlet plates were never reinstalled. I also had some questions about the contract and he was very helpful and had the office fax me the pertinent info that same day. Lesson learned for me was that it would probably have been better to let BWN hire the contractors for the rebuild esp when you are out of town and unable to oversee. When there are heavy rains in the area like Baltimore had in July, it might take a few days for them to process the volume of calls especially if the nature of your request is minor. But they do respond. They are extremely professional and they stand behind their work."

"Once in a blue moon a person may find a contractor with whom they truly want to work--a person who values honesty, has expert knowledge, takes pride in his work, is conscientious, fair and punctual. In addition to these fine qualities, John was gracious, considerate and willing to go the extra mile. He installed a top-of-the-line French drain in my basement, which included features not offered by many of his competitors. It was done in 3 days, to the exact specs he kindly sketched out in response to my questions. When a glitch arose with the backup pump, his employee returned to do a quick fix the same day. After many years and much higher estimates, I finally have a basement that I feel will stay dry even in the worst of weather. I am very grateful."

"We moved into new house and quickly found out the basement had major water issues due to years of neglect (including a clogged and poorly installed English drain from years ago, and a sump pump that while it worked, never pumped water.). Given the investment we made in buying the house, we wanted to make sure we left no doubt in our mind that we were fixing it for the long haul so we could use the basement without worry of mold/mildew for our kids. We had NV Waterproofing install perimeter wide gutter guards, and a new sump pump system and drainage pipes. As soon as the work was done we got rain, and for the first time in the 4 months since we have lived here I saw the water that otherwise would be in our basement actually in the rear of our backyard by the discharge pipe. We have had a few more rains and even one snow and there is nothing better to look at then when I see the water that is coming out of the discharge pipe that I know otherwise would be pooling in my basement and cynderblocks walls, and how that was the case for many years before we moved in. Also, the team that did the work was extremely professional. We have 3 kids and pets and the team was extremely courteous. We tried to stay out of their way during the week they were doing the work, however there were times when we couldn't and the team was extremely courteous and professional. The team lead did an amazing job of explaining to me the work he was going to do, showing me updates, and then afterwards explaining in detail what was done, why it was done, and things for me to look for for in the future. I would highly recommend NV Waterproofing to others based on my experience with them. They did high quality work and were extremely professional."

"Fantastic! Dan (of RPD CORP/Archer Contractors) came out to consult with me about my leaky basement and cracked walls. Dan was knowledgeable, and his understanding of drainage and structural problems gave me comfort in knowing that I have the right group for the project. They installed a drainage system to control storm water, graded the land, and repaired my foundation. His crew came out within 1 week, on schedule, and completed my project in 3 days. They were professional, efficient and exercised care. It'��s been a year since the work was completed and the basement is 100% dry."

"Joey D, James, and Talib were hard workers who took care to protect the areas that were not impacted by their work. They cleaned up the work area very thoroughly. The work included removing dry wall and paneling from the exterior walls of the basement. They trenched around the exterior, installed 2 sumps and drainage channels, replaced 6 window wells, added new drain to the sump in the exterior stairwell, covered exterior walls with moisture barrier, and repaired the concrete. All work was completed in the 5 days scheduled. They communicated well and answered all my questions and concerns. Joey D, James, and Talib make a great team, are employees of JES, and will do a good job for you. They know what they are doing."

FAQs for basement drainage channels installation projects in Kensington, MD

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.
