"Great.! DB’s Plumbing sent Trevor out to fix the problem and he was great. The price was right and he got the drain going fast. He was knowledgeable offered solutions to my other plumbing issues I have at the house. He also gave me a quote for another job I needed done, so I will use them again that’s for sure."

""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

Owners John and Susie Townsend grew up and still live in Nokesville, Virginia. All of our customers are family and friends. For 10 years, we have worked only off of referrals. As our small business grows, we are doing very little advertising in an effort to keep our cost down and pass the savings to our customers.

"My experience with this company was great. I was able to tell them my issues and they gave me several options. Ultimately we went for the full French Drain system. Everything was done on time and the estimates were very fair. Warranty on the work is great. I would call them again if needed."

"Dave and his team did a wonderful job with a new trench and drain system. He tied in 5 new downspouts to the new drain and re-attached and cleaned out a few more downspouts ensuring my home will remain dry during the wet weather. The job was done on time at a fair cost. Excellent communication and overall job well done."

"Our 25+ year-old French drain system in our 100-year-old basement was showing signs of failure, so we contacted several companies to get advice on what to do. Jason of AA Action was very professional and helpful when he performed his initial inspection of our basement, and had very good ideas on what needed to be done. The price he quoted for the work was also, based on what we had read, reasonable. We ended up going with another company recommended by Angi, but only because it brought up a couple of options that we had not thought of, and we felt comfortable with them doing the extra work. We were not at all unhappy with AA Action's suggestions or pricing - it's just that the other company's additional ideas made sense for our circumstances."

"A superior company. They follow through on their commitments. They have long time employees with great experience. BWN waterproofed our leaky basement about 10 years ago. No problems for almost a decade. After a recent weekend downpour we had water along one of the basement western storm-facing walls. We called and opened a service ticket with Gary. They called back in a little over a day and scheduled a repair at our convenience. Joe, a long time employee, very courteous, professional, and respectful, arrived on the job. He had reviewed our prior project and knew the property well. And it was a window well drain that had clogged. Luckily, it was easily unclogged and the problem was completely solved. We have always been pleased with the work and response of this locally owned business."

"Great experience. The previous reviews were spot-on. This business is all Lazaro - you deal with Lazaro from the beginning and Lazaro is there every day throughout the job. He is personable, patient, explains everything clearly, is prompt, responsive, reasonably priced, sensitive to budget, creative coming up with solutions for unique situations, and flexible on scheduling and on changes that may come up during the job. I could tell he was the one when I first met him; he measured everything and listened carefully to my concerns and suggestions. This is entirely unlike the other highly-rated Angie's List big business from which I requested an estimate, who sent a young marketing guy out who provided a fancy folder, did not really listen (just kept saying "yeah, we can do that, and we'll throw in some other things at no additional cost"), took no measurements and provided an outrageous quote. I've attached a before and after picture. My driveway pavers were spreading apart due to poor drainage due to tire pressure over time. In addition to reinforcing the substructure and sloping the driveway correctly away from the house, Lazaro came up with solutions including beautiful gravel side drains and reinforcing the previously spread-apart area with a concrete border hidden under the gravel. He also reset our fence post that had been rising due to the poor drainage and installed a downspout drain under the reset driveway with a pop-up drain on the other side instead of having the downspout pour directly onto the pavers, which also may have led to our previous problems. And he was creative in redistributing our oil-stained pavers in a random pattern so they wouldn't be as noticeable. Great job."

French Drains FAQs, answered by experts

Yes, short hair can clog a drain. While you might be tempted to blame the long-haired people living with you for a clogged drain, hair—no matter the length—can combine with soap scum and leftover shampoo to create a perfect storm of sticky mess that can cause your drain to slow down. 

A clogged sewer line is not typically covered by homeowner’s insurance, though some sewer line issues are covered. For instance, damage related to a fallen tree is usually covered. Though sewer line replacement is not covered in a standard insurance policy, some companies offer add-ons for this purpose. Read the fine print before spending your own money.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

Professionals use snakes, hydrojetting, or chemical cleaners to clear blockages effectively without damaging pipes.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.
