"Half of my project was installing and burying a drainage line to pull water away from my home. Brandon, Sergio, and Terrence did an exceptional job! From the moment they arrived, until completion, they were very courteous and willing to explain any and all questions I had. They even installed and buried an additional drain line from my gutter downspout next to the drain line they were installing and connected it to the yardwell along with their drain line. I would definitely recommend Mount Valley based on the work and character of each of these guys. They reflect good on this company!"

French Drains FAQs, answered by experts

In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

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.

Most blockages can be cleared in 1-3 hours, but severe issues may take longer.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.
