"Our house was built in the 1890's. The foundation is stone with multiple generations of mortar in various states of disrepair. Our original plan of interior foam insulation was disrupted by some dramatic seepage on the north side of the foundation. Northern Basements came to provide us with a few options for repair. The diagnostic visit was very informative and the estimates reasonable. We chose the exterior drain option and sent in our deposit. The team that completed the work was amazing in what they accomplished and their very professional demeanor. We also purchased a dehumidifier system from Northern Basements. One year later all systems have worked very well. The basement is dry and we have had no other issues.

"'what seemed like a simple clogged drain turned out to be more extensive and therefore very expensive, far more than the base quote. However, Carey worked hard to clear the pipes. It took 4 hours. The final bill was 4 times the original estimate; whether $1000.00 was the going rate I have no way to know. It was a lot of work and he solved the problem. He came promptly and stayed till it was done. He knew what he was doing and the work wasn't easy. I'd use his service again."

French Drains questions, answered by experts

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

If you drop jewelry down your sink, it can cause a clog, especially if it accumulates other debris on its way down. However, that is the least of your worries if you drop your favorite jewelry down your drain. If your gold band goes tumbling down the sink drain, don’t panic—refrain from running more water down the sink, and follow the steps above.

A professional drain cleaner is a plumber or specialized drain cleaner with the necessary tools to unclog drains and tiles to keep waste water flowing out to the septic tank or city sewer for processing. Keeping wastewater from backing up into your home helps keep you and your family safe from potential contamination and sickness. These pros can help resolve nearly any drain situation in a safe and efficient manner.

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.
