"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."

"Tru Integrity, LLC lives up to their name. My basement flooded twice this year due to sump pump failures so my husband and I knew it was time to make some major changes. We interviewed 3 companies, even big name companies and Wendell (the owner) was the only one that explained things and did a thorough assessment of our property to figure out how to fix our sloping and minor foundation issues and within our budget. His team arrived on site on time and worked a full day until the job was completed. Our basement was left cleaner than they found it. We added another sump pump due to the size of our basement and that drain well looks better than our original. This will allow any water that maybe overworking the main pump to be redirected and pumped out on the opposite side of the house. I'm happy with the look and everything is so quiet now."

"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."

"I had a great experience with Best Buy waterproofing. I contacted them for inspection due to water rising underneath my tile in the basement. They responded very quickly and had someone out for the inspection a day later. Ed completed my inspection and was very informative and communicative throughout the whole process. He didnâ t try to scare me into getting any services and was very patient with me. Any questions I had he was on it and available. When I made my final decision it was quick and a painless process. The crew cleaned up well and walked me through the work they had done. They installed a new drain and sump pump. Might I add they made my installation very esthetic by placing the line in the wall to hide the pipes when the dry wall is replaced. I will definitely recommend to friends and family!"

French Drains FAQs, answered by experts

The cost varies from $150 to $600, depending on the severity of the clog, pipe access, and required equipment.

A plumber can get to the bottom of your smelly drain and clean it with specialized jets, hoses, and drain-safe cleaning solutions. It is also smart to call in a plumber if you suspect your drain smell is coming from a stubborn clog or even a leaky pipe.

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

To keep window wells from filling up with water, you need to stay on top of maintenance. Remove debris as it fills up, and regularly loosen the gravel at the base if it’s become compacted. You can also reslope your yard to make sure water flows away from the window well (and your home’s foundation), and you can even install a window well cover to prevent debris from building up. Installing an actual drainpipe at the base of the well can also prevent window well drainage problems.
