"They installed a french drain and pump and installed water proofing on the walls.  Initially I thought some of the workers were not really the best, so I called and a manager came out and was very honest and acknowledged their faults and came out and fixed all the issues.  I was very impressed with this, he was very responsible.  They ended up doing a fantastic job in the end."

"Fast Estimate , had many estimates from other companies and Waterproofing One was the best price for Us , Joe was very confident and knowledgeable and gave Us good suggestions for our leaking basement, the crew that installed the French drain inside were great, install looks very professional. I figured we’d have a mess to clean up after the install understandably. But wow they did an incredible job cleaning up afterwards. Not a speck, they even spent time cleaning off the driveway and front lawn. We have been through one major rain storm since the install and not a drip of water. So far so good , we are getting an expected 3” in the next 24 hours and it’s a relief to know I don’t have to stress about rain storms anymore!"

"The job was to put a sump pump and French drain into a crawl space off my basement. It was completed in a timely fashion. They removed all material in the crawl space and also sprayed an anti mold solution. When I called company to ask questions Jason kindly explained the answer."

"All the work was done according to our contract and crew of four men stayed until everything was completed, about 6:30 pm. Installed interior French drains and sump pump. They worked together well and quietly, leaving work areas free of debris and dirt/dust at end of project."

"The crew was efficient and answered all our questions. The only reason I didn't give them a 5 rating in customer service is because the sales rep didn't communicate clearly enough with the work crew about no large equipment on our drain field."

French Drains FAQs, answered by experts

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.

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.

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.

Clogged pipes are one of the top signs your water heater is about to fail. Potential symptoms of excess sediment buildup include not enough hot water, leaks, unusual noises, low water pressure, and discoloration or odors in the water.

Baking soda and vinegar is a great solution for cleaning your sink drain; in fact, it’s our preferred method. Here’s how to unclog your drain with baking soda and vinegar: Pour in a half cup of baking soda, then 1 cup of white vinegar, and let the two bubble for 15 minutes. Then rinse out with boiling water. This method is much safer than using a chemical drain cleaner gel.
