"Jeff came and was very informative on the overall process and probably the best information I have received to date from anyone. He was very thorough and went thru the process he was performing step by step in a way I could understand. Looked at other causes to see if drain was clogged as week and cleaned up all the dirty areas. Would definitely recommend him to all neighbors and family. Great job Jeff. Thanks"

Customers say: Terrific value

"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

French Drains FAQs, answered by experts

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

The best drain cleaners are biodegradable ones or a mixture of baking soda and vinegar. Strong, caustic chemicals may seem appealing with promises of unclogging your drain quickly, but liquid drain cleaners can cause damage to your pipes over time. Consider making your own drain cleaner with baking soda and vinegar.

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

You should not attempt to snake your sewer yourself. Accessing and snaking your sewer requires heavy-duty equipment, and while renting is possible, misusing it can damage your sewer main and leave you with very expensive repair costs, not to mention potential environmental issues and severe water damage. Accessing your sewer also exposes you to hazardous sewer gasses, and failing to seal the sewer properly after work can be very dangerous. It’s always best to hire a professional sewer cleaner near you to handle this type of work.

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.
