"The plumber they sent had to dig up the front lawn to find where the water line entered the house. He then replaced the grass and you couldn’t tell where he dug. He was the reason I gave them a 5 star rating. He worked till dark to complete the job. Most companies would have used 2 guys to do this work. Ask for Jeremy he is an excellent plumber."

"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 the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.

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

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.

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.
