"I hired Flatirons Plumbing to install a hose bib in my garage. This required them to run a pipe from the adjacent bathroom sink, through the drywall, into the garage. Flatirons was the second quote I got for this job. The competing quote was about 50% less, but the other plumber wanted to rip out a large section of drywall to find a pipe. I would have been responsible for replacing all that drywall afterwards, at unknown expense. Flatirons was able to drill a hole in the wall, with no other drywall damage. I docked one star for professionalism, because they tracked mud on my floor and did not clean it up."

"Had them replace a drain pipe in my foundation. They were timely and efficient. Price was very good as I have been through this nightmare before. Really appreciated Keith and Nico! When Keith arrived, I instantly knew I had the right guy advising me on this. Nico did a great job doing the job. Thank you both."

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"I had a clogged kitchen drain on a weekend, a challenging time to find a reasonably priced plumbing company. After several unsuccessful calls, I made an appointment with an expensive service for the same day. I received a call back later in the day from Jason at Afford-a Router. He answered my questions and made an appointment for the same day. He arrived at the house, reviewed and resolved the problem in twenty minutes. He was professional, answered my questions, and the charge was very reasonable, considering it was a weekend. I highly recommend their services and will use them again."

"Eagle did a great job at a reasonable price. I got several quotes that were way out of the ballpark (I knew this from my time remodeling homes) but Blue Thunder was right in a decent price range. Everything was done with the new kitchen sink install to a great level of quality. It looks much better than it did before and I will definitely use them on my next project."

Drain Pipe Installation FAQs, answered by experts

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.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

You may have a clogged gutter. Downspouts can also clog if your gutter collects too much debris. Hire a professional gutter cleaner, and if you still have problems, install a gutter guard (which prevents debris from entering your gutter system) and a downspout extension (which helps drain water further away from your foundation, so it doesn't pool near your house). Follow these tips to keep your gutter downspouts clean.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.
