"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."

"Todd made a trip to my home to assess my needs We discussed types and brands of fixtures and he recommended those with which he has had the best outcomes in service and reliability. He purchased the faucets and a couple days later came to install them. He was pleasant to have in my home, worked in a very professional way, gave good advice for future projects, and cleaned up. I valued his professional work ethic and advice on future projects. I will definitely call him when I need more work done."

"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

First, find the cleanout pipe in your yard. Unscrew the cap—you may need a wrench to do so. Then, get a drain snake. You can use a non-motorized one, but a motorized snake will make the job a little easier. Feed the snake through the pipe until it reaches the clog. Spin the snake continuously, but don’t try to feed it through the pipe anymore. Keep spinning until you feel it break the clog apart.

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.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.

Coke and other sodas do clean a clogged drain, so this is one of those urban myths that has some truth behind it. Coke and similar sodas are caustic and will provide some cleaning power to your drains. However, the power of soda pales in comparison to dedicated cleaners or even baking soda.

There are several signs that can indicate your leach lines are broken, failing, or in need of repair, including puddles of water or a marshy consistency to the ground above or around the pipes, slow drainage or plumbing backups inside your home, and noticeable odors or gurgling sounds coming from your leach field. Keeping your septic system properly maintained, including having your septic tank pumped at regular intervals, can help ensure your leach lines stay in good working order for a long time.
