"Daniel was awesome to work with. He came out and provided a solid estimate in a timely fashion. We had an unexpected sprinkler line that was in the middle of our excavation area and he took care of that. He also provided the materials for a retaining wall that we hadn't initially planned for, and he added that to the project scope without issue. I will definitely reach out to Daniel if we have another project like this one."

French Drains FAQs, answered by experts

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.
