"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

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

If the drain pump on your washing machine is continuously draining, it could be that the control board is damaged and requires repair, or there’s a clogged or kinked drain hose. If you can’t locate the problem, you’ll want to have a plumber or appliance repair expert come take a look.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.
