"Once and done waterproofing helped me out with a small annoying leak Iâ  ve had around a pipe. The owner called me right away, came out the next day for an estimate, and fixed the leak the day after. His crew is friendly and courteous and hard working. Explained every step they weâ  re doing. Did such a great job, I had the bury some drain pipes and install a rain water reservoir. Very reasonable pricing and veteranâ  s discount."

"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!"

"$9,500 I was quoted for my concrete driveway and porch to be removed and a new concrete driveway and pad poured. I needed a culvert installed under the foot of my driveway for rain water drainage, it was agreed that a 4" pipe would work. When the crew came out to do the work, the demolition part went very smoothly but when it came to the drain I was told I needed an 8" pipe. The trench was dug for it including digging an 8" deep by 1 foot around hole in my nabors parking pad. Than I was told the grading was wrong. I told him water wasn't draining because the trench he dug for the 8" pipe he suggested was below the rest of the drain lines and the water will not flow untill it was leveled back out. He argued with me about it for about 3 hours wile the concrete was starting to be poured. After his own workers and I told him the 8" pipe would not work, we went back to the originally quoted 4" pipe and everything drained fine. After the concrete was completed the work looked great."

French Drains FAQs, answered by experts

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.

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

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.
