"Was polite and professional but didn't have the tools needed to properly unclog my underground gutter drain which was clogged with roots. Tried a mechanical auger that he had but that was all he could do and only pulled thin roots which helped but didn't completely unclog the drain."

"Sterling was a great technician he worked extremely hard to clear my toilet drain. They really take pride in there work at this company and completely explained me the process and everything that was involved. I had roots clogging my toilet drain and Sterling was able to locate and remove the root issue and provide me with video evidence of just how clean the drain now is after the service. Very happy with the service provided."

"We received quotes from four companies - Drainage & Erosion Solutions' pricing was fair and the quality of their work & our experience with them seemed too good to be true. So much so that I've waited for nine months to post a review to be sure the drains they installed addressed the flooding issue. The project included installing five catch basin drains, over 70 feet of 4 inch drain pipe and another 70 feet of six inch drain pipes as well as replanting flower beds, regarding several areas, and installing river rock in two of the drainage beds. The drains have performed exceptionally well. What used to be a river forming on one side of our house, now quickly drains into five catch basin drains they installed. In addition, they were very concerned with aesthetics and made the drain areas look wonderful. They were prompt, professional, and a pleasure to work with. I would highly recommend them. Also, and perhaps most importantly, their recommended solution addressed the root cause of our flooding issues. Two of the other companies we received quotes from accepted that water would get into our crawlspace as a premise. Drainage and Erosion Solutions actually made sure that wouldn't happen in the future."

French Drains FAQs, answered by experts

Yes, frozen pipes can cause a toilet to stop working correctly. If the pipes are frozen, water cannot flow, which can lead to two main problems. First, the supply line to the toilet tank may be frozen, which prevents the tank from refilling with water after you flush. Second, the drain pipe itself can freeze, blocking water from flushing away. As a temporary solution for a non-refilling tank, you can manually add water, but this is not a long-term fix. To clear a frozen drain pipe, you can try pouring warm water into the toilet bowl or tank and then flushing, as the warm water may help thaw the ice blockage. Ultimately, the best course of action is to unfreeze the affected pipes to restore your toilet to full functionality.

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.

It’s sometimes difficult to distinguish a clog from a frozen drainpipe since ice technically causes a clog. If the temperature doesn’t tip you off, there are a few additional signs that your pipe is frozen. Look for condensation and frost around the pipes. Ice in pipes can cause a banging or clanking noise as opposed to a clog from a softer material.

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

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.
