"Northern basements was able to fit us in quickly, pulled our crooked cement wall back in-place and sealed the wall to prevent future leaks.  The work was timely, communication was friendly and detailed, and price was as to be expected for the large amount of work that needed to be done.  We are very pleased with the whole process as well as the results.

"Kfgconcrete is an excellent company that strives to fully satisfy. This was the only company that truly listened to my desires and made sure to explain all possible options. Kevin was patient with all my questions (and I had a ton of them)! The end was everything and more than I was hoping for. While it was not the cheapest pricewise, the cost was worth it in the end, and you get what you pay for. You made my family very happy and proud of our walkway. Thank you!‎"

French Drains FAQs, answered by experts

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

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.

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

Once you’ve poured the baking soda and vinegar into a drain, you should wait about 10 minutes for the mixture to break down the clog. If you try the baking soda and vinegar method and it doesn't work, you can do it again or try the baking soda and salt trick.

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.
