"The workers were hard working. Did a great job. The only concern we had was the lack of attention to the workers: no porta potty and no machinery to help carry the heavy concrete. Still waiting for the $250 gift card reward, lol!"

"We received three estimates on this work, and SD Water Damage/Restoration was almost 5K less than the two others, who were also on Angie's List. The workers arrived on time (or slightly early) for the estimate meeting and on work days. The woodwork was outstanding, and the workmen even made small repairs at no cost on several drawers. Our impression of Mr. Bennett, who did the actual woodwork, was that he was a craftsman of the highest quality and took pride in his work on every level. If we had it to do again, we would have draped off the living room, as the sanding required extensive cleaning afterward. We would recommend this company for honesty, integrity and value to anyone."

French Drains FAQs, answered by experts

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.

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

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.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.
