"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

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.

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

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. 

Clogged pipes are one of the top signs your water heater is about to fail. Potential symptoms of excess sediment buildup include not enough hot water, leaks, unusual noises, low water pressure, and discoloration or odors in the water.

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.
