"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"Andrew and his Crew from Roseburg were wonderful. They were able to get into our crawl space and did an amazing job clearing it out, installing drainage, a layer of plastic and sump pump. They left the area so much cleaner than it was when they arrived and they explained everything to us clearly so we would know what to do. We recommend them highly and it was a pleasure to meet them."

"Jamison and his crew were absolutely awesome to work with. I would and already have recommended them! Once they started the job they worked until it was finished and cleaned up after. They poured 43 yards of concrete, with 50% of it colored and stamped for our driveway and patio. They were very meticulous around the screens and covered our home with plastic to ensure there was no splatter. They were also very meticulous with the underground drain system for our driveway. The kept us informed the whole way through so we knew what was happening and what to expect. Our slopped driveway turned out awesome and our patio is stunning!"

"I'm waiting to receive their proposal today, but when he came to see the project site yesterday, Dustin was professional, on time and very thorough in his assessment of the problem. I learned a lot about French drains."

Foundation Drain Installation FAQs, answered by experts

If the time has come to install a French drain in your yard, basement, or crawl space, there's a solid chance you've been battling water damage—or the threat of water damage—around these areas. Thankfully, proper drainage should allow you to redesign these areas of your home without the fear of being inundated during the next storm. If you've had to remove a portion of your lawn for an exterior French or curtain drain, consider reseeding your lawn to patch up the spot. You can also take this opportunity to enhance your foundation waterproofing methods or even start thinking about finishing your basement .

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.
