"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"Hire them! Paul came out his with his partner and gave me the lowest quote I could find to hydro jet my area drain in my concrete driveway! Not only that, they came first thing in the morning like I wanted them to, saw the problem, cleared the drains out, and the cleaned up after themselves. They are true professionals who don’t give up on a job and make sure you get the problem 100% fixed. I would definitely recommend them for any hydrojetting service you may need."

"Daniel responded to my request for a quote very quickly and then came out and diagnosed the problem same day. He was very respectful and even took his boots off as he came inside so that he didn’t tack any dirt into the house. He was able to fix the faucet, clean up, and get the water turned back on with in a couple of hours, all for a very reasonable price. Will definitely use his serviced again."

Drain Cleaning FAQs, answered by experts

Regrading your yard can often fix drainage problems. You can also try aerating the lawn to encourage better drainage or install a new drainage system to prevent water from pooling in certain areas.

The first rule of plumbing is nothing but water, toilet paper, number one, and number two go down the drain. 

To prevent clogs, get yourself:

  • A compast pail where you can clean plates, drain grease, and toss scraps and paper towels. 

  • Drain screens for the shower, tub, and bathroom sink to stop hair, jewelry, toys, etc. from going down the drain.

  • Trash cans for everything that shouldn’t go down the drain, like dental floss, hygiene products, and cat litter.

P.S.: If you do drop your priceless ring down the drain, take a deep breath, and then follow these steps to retrieve jewelry from your drain.

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.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.

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.
