"Mark told me he would be at my house at 10:30 and he was. He spent close to three hours to unclog the drain that backed up into my dishwasher. He took all the old plumbing from under the sink and replaced it with all new pipes and fittings. He tested everything to make sure there was no leaks before he left! Excellent job! I will recommend him to my family and friends."

"Aaron Lenker add Corbin Gillichbauer of Groundworks leveled concrete walks around my corner lot in Montoursville Pa. They arrived around noon time and were finished about 5 1/2 hours later. They did their work very professionally. They did an excellent job. I would rate their work 5 of 5 stars."

"Jon is professional and a man of his word. My wife and I had some leakage in our finished basement. After substantial research, I contacted several companies in the area. Jon and his crew at Eastern responded faster than every other company and offered us the best price for the least hassle. The crew works hard and fast. They were respectful of our home and property and cleaned up after themselves when they were done working. Our interior foundation drain is working great and can sleep in peace knowing that our basement is dry, even on the wettest nights.They stand by their work and even came out to install a false floor under our oil tank after we replaced it., at no additional fee. I would 100% recommend Jon and his crew for all of your waterproofing needs."

French Drains FAQs, answered by experts

If methods like hot water or a plunger don’t work on your clogged drain, you can snake your drain to dislodge the plug. This can be a messy process, taking some physical effort and additional time over the other drain-clearing options. You can purchase a drain snake at a hardware store and choose from handheld options or those attached to a drill. Just work slowly, and be ready to call a plumber if you’re unable to reach the clog from your drain or P-trap.

Common causes include hair buildup, soap residue, food particles, and foreign objects. Older pipes can also contribute by facilitating buildup more easily.

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

Drain pipes carry wastewater from sinks, toilets, showers, and other fixtures to the main sewer line. They’re typically located within the walls and floors and beneath a home’s foundation. Meanwhile, sewer pipes transport collected wastewater to a septic tank or a municipal sewer system.

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.
