"We had a crack in our poured concrete foundation. We had estimates from other companies that involved waterproofing the entire lower level (it was already waterproofed) at very high prices without even addressing the crack. Eco-Seal Home Solutions addressed the problem we needed fixed, gave us a fair price, and completed the work in just a few hours. We will call them again if we have any other foundation cracks. Great work."

"Beck's did an amazing job with my plumbing! The technician, Dan, was awesome—professional, likable, and very knowledgeable. He took the time to explain exactly what was going on, and he fixed the problem very quickly. I would highly recommend this company!"

"my garage had a major flooding issue, they installed French drains around the perimeter and tied the line into a existing well i have on my property, they did a great job and cleaned up after themselves. Now I no longer have puddles making their way through my garage every time it rains, excellent work. i would do business with them again."

French Drains FAQs, answered by experts

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

Yes, you can use vinegar to unclog a dishwasher. To do so, combine 4 tablespoons of white vinegar with 4 tablespoons of baking soda and pour the mixture down your dishwasher’s drain. Let it sit for 15 minutes, then pour a cup of hot water down the drain to flush everything out. Finally, run a rinse cycle on your dishwasher to see if the clog is gone.

Yes, short hair can clog a drain. While you might be tempted to blame the long-haired people living with you for a clogged drain, hair—no matter the length—can combine with soap scum and leftover shampoo to create a perfect storm of sticky mess that can cause your drain to slow down. 

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

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.
