"I called Star Plumbing on a Tuesday to fix a clogged drain in my kitchen sink and bathroom shower. They gave me an appointment for later that same day. They were professional and knowledgeable. They talked me through the work and recommended solutions to keep the problem from repeating. I have experience with several big name plumbing companies over the last 20 some years and Star Plumbing gets my vote as the best I have ever worked with. And, you can't beat their prices!! In fact, I called them the very next day to fix a plumbing problem at my office."

"David & his team with Arcelio did an outstanding job! We needed it done on short notice & they rose to the occasion. And just before a weekend of heavy rains. So our basement went from waterfalls of leaks to dry as a bone, despite the heavy flooding outside. They took lots of pictures of the process so we could see all the work they did underground. They were reasonably priced & did the job done with good attention to detail & pleasing aesthetics with the river stone. We love that they guarantee their work. We're very grateful to have chosen Drainage & Erosion Solutions. We kept seeing their signs & trucks in the Del Ray, Alexandria neighborhood over the years & we can see why others chose them, also."

"Suma responded to our request to snake our basement floor drain. Upon inspection we were quoted a price for the job which we felt was reasonable. The technician completed snaking the drain and then tested it thoroughly to be certain it was clear. Very professional."

French Drains FAQs, answered by experts

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

To keep window wells from filling up with water, you need to stay on top of maintenance. Remove debris as it fills up, and regularly loosen the gravel at the base if it’s become compacted. You can also reslope your yard to make sure water flows away from the window well (and your home’s foundation), and you can even install a window well cover to prevent debris from building up. Installing an actual drainpipe at the base of the well can also prevent window well drainage problems.
