"Sterling was a great technician he worked extremely hard to clear my toilet drain. They really take pride in there work at this company and completely explained me the process and everything that was involved. I had roots clogging my toilet drain and Sterling was able to locate and remove the root issue and provide me with video evidence of just how clean the drain now is after the service. Very happy with the service provided."

"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."

"Water started leaking into my finished basement this past winter. Dan, from Archer Contractors, came out a few times, free of charge, to troubleshoot. He patiently and methodically examined all the potential sources of water entry while keeping suggested repairs to a minimum. He discovered that the cause was a back yard drainage problem together with a failing internal foundation drainage system and drew up a price quote with detailed diagrams for a plan to remedy the situation. The crew started immediately, keeping within the scope of work and cost outlined in the price quote. They installed a back yard drainage system to control storm water and replaced the blocked portion of the foundation drainage system. They were very professional and quickly but carefully completed the work, leaving the site spotless. Since then the basement has remained dry during numerous heavy rain falls, even during the rapid snow melt with rain that occurred this past January. I would definitely recommend Archer Contractors for any yard drainage or basement waterproofing issues. Not only was the work done properly, but Dan was careful to suggest only necessary repairs to keep the cost to a minimum."

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"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!"

"Manuel Guzman (foreman) Brando Amaya and Jeffrey Amaya did an excellent job building a french drain and installing a sump pump in our basement. All of our questions were answered completely and politely. All 3 worked very hard and were true professionals. We would highly recommend them for any similar project."

French Drains FAQs, answered by experts

Water leaking through your basement floor is a good sign of a clogged drain, but another sign of a clogged basement floor drain can include unpleasant odors coming from the drain. Also, hearing gurgling noises when water drains from the basement or having other plumbing fixtures (like toilets or other drains) backing up is a good indicator.

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.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

If your washing machine drain is clogged, that isn’t a good sign. Unlike toilet drains or kitchen sink drains, there isn’t matter that is easily broken up with a plumbing snake, and more care is required. If you’re in an old house or have mineral-rich water, there could be a buildup inside the pipe. Either way, if the blockage isn’t obvious and doesn’t dislodge with a snake, you need to call a pro—otherwise, you risk damaging integral plumbing.

Never pour used motor oil down the drain. Doing so can have serious environmental consequences, including contaminating groundwater, endangering animals, and killing vegetation. It can also clog your pipes, causing backups in your plumbing or the wastewater treatment plant. In most places, pouring motor oil down the drain is illegal, whether you do it in your home or a storm drain.
