"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."

"well... the work was done by Ecowater Northwest who is no longer. Reason for the review is that when I stopped hearing from Ecowater Northwest, I found out they were bought out by Culligan. Which is confusing because if you google Ecowater Northwest, you get Wolfer's Heating whose website claims they now own EcoWater Northwest. It seems Culligan got all the old customer files from Ecowater Northwest and Wolfer's got the rights to carry the Ecowater brand going forward. So I called Culligan last year and they found my file from Ecowater Northwest and they said they could support me for replacement filters for the systems that EcoWater Northwest had installed in my home. Great. For a while.
Fast forward to today.. I haven't heard from Culligan since July of this year. The way Ecowater Northwest operated, they would send notices to their customers when it was time to replace filters. I have 4 different filters in my systems and sure hope Culligan is tracking it. The Ecowater RO filters are proprietary and not allowed for sale on the internet - so you are locked in to a Ecowater dealer. Who is it.. Culligan? or Wolfer's? Who's going to continue the maintenance agreement of notifying legacy Ecowater Northwest customers that it's time to replace filters?

"They came out inspected the foundation and told me there were a couple of small cracks and it was caused by normal settling of the house over time. They said it did not need to be repaired. I asked about the cracks in my garage cement floor. They told me they could repair it for several thousand dollars. They it was normal for the floor to crack. They only recommend repairing it if the cracks rise an inch or two and become a safety hazard. Then he explained how I could make the repair myself. I am very appreciative of their honesty and offering a less costly solution. They did not have to do."

Foundation Drain Installation FAQs, answered by experts

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

Your sump pump will discharge water through a discharge line or pipe. The discharge line should be placed at least 10–20 feet from the foundation to avoid any issues.

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 .

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
