"We hire Geico Builder to handle our home renovation, including updates to the kitchen and bathroom, and the whole experience was fantastic. The team was professional, organized, and easy to communicate with from start to finish. They showed great attention to detail, stayed on schedule, and made sure everything turned out exactly how we envisioned it. Our kitchen looks stunning, the new bathroom layout is so much more functional, and the bedrooms feel brand new. It's rare to find contractors who combine quality work with honesty and reliability, but Geico Builders delivered on all fronts. Highly recommend them for any home remodeling project."

French Drains questions, answered by experts

A saturated leach field can be the result of many underlying issues, so the best way to treat the problem is to call in a professional septic company. Depending on what’s causing the saturation, the professional may pump out your tank if it’s full, add more bacteria to your tank, or recommend rerouting rainwater and runoff from your house away from the leach field using gutters, downspouts, and downspout extenders. They might also recommend planting certain plants over the area to soak up some of the excess water once the initial problem is fixed.

Pouring drain cleaner down a vent pipe isn’t recommended. First of all, unlike a clog in a sink or bath caused by such material as soap scum build-up, toothpaste, and hair, clogs in a vent pipe are likely the result of debris from trees or even an animal stuck in the pipe. Drain cleaners won’t be able to eat through this kind of material. The cleaner will only become clogged in the vent with the debris, causing even more problems.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.
