His crew was very polite and did an excellent job explaining the work that was being done. I would highly recommend Mike and his company to get the job done right."

"Out of the three basement waterproofing experts we called to offer solutions after getting a lot of water in the basement of our 1925 home, Joe at The Real Seal was the only one who seemed to take serious time in investigating the cause. He even came back a second time after we got more water in another spot to see what could be causing it and what a cost-effective solution might be. On top of that, the price was right! We never ever felt pressured into committing to the work, and they seemed confident in their skills to get the job done. Our partial interior drain tile job was finished in two days. While we can't yet vouch for the drain tile's efficacy since we haven't gotten a large spring rain yet and we're still in the process of refinishing our basement after it was demoed for this work, we expect we'll have a dry basement!"

"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"

"The estimator (Kaz) was prompt, informative, and responsive to my many queries before I signed a contract. The project manager and workers were all very prompt, professional, and courteous. They were respectful of our property and that of our neighbors, taking off their shoes when inside and cleaning up their work. I asked them to run an additional line from one of my downspouts, which was done without incident. We also worked together to problem solve an issue related to the sump discharge line. On day 1, they cut our buried cable line because it was marked incorrectly. However, the foreman called the company and it was resolved/fixed within a few hours (it has taken more than a day in the past when I’ve called!). I was quite surprised at how they cleaned up after excavating for the 6 inch drainage pipes. They estimated 5 days to complete the work and finished in 3 days. While I was not excited to spend that much to fix the problem, we knew we needed to address the improper drainage. Additionally, while I feel that I know what needed to be done and probably could have done so myself for less money, it would have taken me 3 months, not 3 days with my schedule. Overall, I’ve been pleased with the work and may have them come back and address an additional drainage issue in our yard in the future."

French Drains FAQs, answered by experts

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

It takes hair about two years to dissolve on its own in the drain without the use of any tool or help. Fortunately, using a drain snake, plunger, or any of the actions mentioned above to dissolve the hair will help get rid of the clog in as little as 15 minutes. 

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.
