"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."

"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."

"Rob came out to my home as I had leaks coming from unknown source. He has EXCELLENT COMMUNICATION, asked many questions over the phone to assess the problem possibility before he come out. Rob picked up the parts he thought he would need, checked all the possible problem areas and went right to work. The problems were solved in no time, and recommendations to replace were given. Rob is the owner and a very pleasant gentleman. I would call him again for help."

Foundation Drain Installation FAQs, answered by experts

Almost any kind of home can have a wine cellar or cabinet installed. You’ll need an area where a concrete floor can be put in, along with the necessary insulation, climate control, and ventilation systems. If you think of yourself as an aspiring sommelier, an underground wine cellar may be ideal, but it will cost significantly more. 

What you choose to install really depends on your budget and how many bottles you’re looking to store.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.

A sump pump's lifespan is typically 7 to 10 years, though the general range can be anywhere from 5 to 15 years. The specific type of pump is a major factor: pedestal sump pumps last an average of 20 to 25 years, whereas submersible sump pumps last between 5 and 15 years. While pedestal pumps are less expensive to service, they are also louder and more prone to clogging.

Several other factors influence longevity, including the pump's quality, usage frequency, and maintenance schedule. A high-quality pump that is well-maintained in a dry climate may last for two decades, while a lower-quality, poorly maintained pump in an area with a high water table or frequent flooding may fail in six years or less.

Regular maintenance, including annual inspections and tuneups from a professional, can significantly extend the pump's life. It is time to consider a replacement if your sump pump runs constantly, cycles frequently, shows visible rust or corrosion, or trips a circuit breaker. As a preventative measure, many homeowners replace their pumps every eight years. It's also worth noting that a manufacturer's warranty can indicate expected lifespan, and some home insurance policies may not cover water damage from a pump that is past its recommended replacement date.
