"My existing window well had pulled back from the homes foundation over the past 20 years, allowing water and sediment to enter the well. Sediment would plug the drain causing water to build up and create an aquarium in the window well. You pass waterproofing installed a new window well and securely fastened it to the cement foundation. They carefully removed the previous window well and took care not to brutalize the surrounding landscape. Completely satisfied with their work"

Customers say: Quality work

"He was very professional, removed the toilet, not only did he replace the wax ring, he caulked around the outside of the pvc pipe which made sense, that way if there was a leak again, it would be noticed in the bathroom and not on the ceiling of the finished lower level. He knew what he was doing, explained everything as he was working."

French Drains FAQs, answered by experts

Yes, many services include camera inspections to identify the cause of the blockage. Confirm with your provider.

No. You should dispose of all oil-based finishing products through a local hazardous waste program. Not only can oil-based finishes be hazardous for the environment if disposed of in the sink, but they can cause clogs in your pipes and stop up your drains. Most municipal garbage or waste disposal companies have a specific location or pick-up schedule for hazardous materials, so that’s your best bet to get rid of excess finishing products.

While there is no specific “best” method to clear hair out of a drain, several options work well. Using a combination of baking soda and vinegar to dissolve the hair clog is a great and easy way to help clear the drain. Drain snakes are also effective for more severe clog buildups. 

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

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.
