"I had a flood for the first time in the crawlspace and basement. I called Regional Foundation & Crawlspace Repair to come out. They wanted 27K for crawlspace encapsulation, that was too much and I could do most the work myself. I instead paid them $5,000.00 to bury a geodrain and install a triple safe sump pump system. This is the job they did, they installed the sump pumps at the 3rd to lowest point in the crawlspace and this geodrain goes back and forth from uphill to downhill. The lowest point still allows water to flood downstairs. They also cracked a chunk of my foundation at the point of sump pumps egress. Outside they just threw rocks on ground were the water comes out and can get back into the ground to reenter the crawlspace. They got 1 star because the people were nice, their job was not. Update as of 4/23/2024 they contacted me and said they wanted to make sure everything was good. A Girl and guy came out and noticed a couple things I didn't and said they would fix it that their company does not do work like that. They dug up all the previous geodrain and moved it to walls, tried to level out the drain and changed the location of the pumps and the drain outside. She had a really good work ethic and never took a break. The guy was on the other side of house and think he did good too. Everything they did looked professional and looks like they fixed everything. They had to come back today to finish the work today, but had three of them. It all looks good and they tested everything. They apologized about the old work and were not sure went wrong, but I don't have a negative view of the company now and am satisfied with the work they did. Just nocking one star for the under trained individuals that came the first time, the second crew was great!"

"Couldn't identify project accurately from dropdowns: fixed my crawlspace and installed a dehumidifier. The team did an excellent job and finished in about 1/2 day. I can highly recommend the company AND the team (Shane English - foreman, Luke Bolinger, and Riley Lane). Happy Customer!"

French Drains FAQs, answered by experts

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

Clean regularly with non-abrasive cleaners, avoid pouring grease down the drain, and check for leaks under the sink.

The cost to clean a sewer line is about $370, ranging from about $190 to $550 on average. The specific cleaning method and the problem's severity will impact the project's overall cost. Some of the most common sewer line cleaning methods include:

  • Snaking or rodding: $100–$250

  • Hydrojetting: $350–$600

  • Chemical treatments: $600–$1,000

  • Repair or replacement: $1,000–$7,500

Boiling water helps unclog a drain, but usually only with a harder abrasive such as baking soda or vinegar. On its own, it isn’t the most effective tool. In addition, you shouldn’t use boiling water if you have PVC pipes, as it can soften or melt them. Use a plunger or enlist the help of a pro if you have plastic pipes.

Avoid flushing non-degradable items, schedule regular inspections, and address minor clogs promptly.
