Choosing a Trusted Waterproofing Company for Your Oregon Basement

Wet basements are not fun! Flooded basements are a homeowner’s nightmare. If you are suffering from constant worry about the health and safety of your basement, it’s time for a change. If you’ve tried DIY efforts to fix pooling water, cracks in your foundation, leaky basement windows, or high humidity, it’s time to find an experienced, professional waterproofer you can trust. A wet basement wastes valuable living space, damages building materials and stored possessions, pollutes the indoor air, risks the health of those living in the home, and puts your investment in your home at risk. That adds up to considerable risk.

Look for expertise, training, and experience

When you choose a basement contractor in the Basement Systems network, you get a local company trained, experienced, and dedicated to the best waterproofing practices. Each contractor listed here is an expert in the diagnosis of sub-grade moisture problems as well as the design and installation of proper drainage, moisture and humidity control, and basement materials. Say good-bye to your wet basement with the best basement waterproofing in your neighborhood!

Why Do Oregon Basements Get Wet?

Flooded basement: Oregon experiences extensive variation in precipitation. The deserts of eastern Oregon get as little as 8 inches annually, while Oregon's population centers, which lie mostly in the western part of the state, are generally moist and mild, with about 200 inches annually. With this amount of precipitation, flooding is a serious concern for Oregon homeowners.

Other reasons for wet basements: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

    Customer Testimonial

              John's Waterproofing came out and encapsulated my crawlspace two years ago. When I decided it was time to finish my basement, they were the only company I called. Throughout the process the crew has been very respectful, clean and thorough. They made sure that my entire basement was sealed off and covered in plastic so that they did not get dirt or mud anywhere in my basement during the process. Manuel answered my questions when I had them and did not mind when I popped my head in to check on their progress. I was very happy with the work they did. Now the space fits with the rest of my finished basement.

              We are currently doing our own independent research to make sure this is the best option for our house. I'm feel great about how Casey explained things to me, I just like to do a little of my own research on the side for piece of mind. Casey gave us more than enough information during his visit so we now have a great understanding of where the project rooted from and the next steps would be. Casey was extremely professional and clearly knowledgeable in the field. The long term guarantee is the most comforting thing for me and my family as we now know homes are constantly shifting and changing. Thank you TerraFirma for everything.

    Customer Review

    By Amy Williams
    Bend, OR

    I wanted to take a moment to let you know what a fabulous crew you sent to our home. We had crawl space trenching and sump pump installation done at our house on August 5-6. Wesley and his crew of three guys did the work. I was very impressive by the crew. They were very professional, polite, and pleasant to have around. The work they did was difficult, as our house has rock under it in some places. Regardless, they did a thorough job, hammering through the rock in several locations. Wesley suggested a pump discharge location that was visually much better than the one I had in mind, even though it required extra work and pipe. Finally the clean-up the crew did was very thorough. They wiped down door handles, swept, and cleaned up every stray rock. One crew member even asked if I could use any extra rock in my landscaping and filled in one area beautifully. You never know what you are going to get when you have work done at your home. I am very glad that we chose TerraFirma and will definitely recommend you, should anyone I know need your services. Sincerely, Amy Williams.

    Customer Review

    By George B.
    Bend, OR

    Jake presented a good plan, which avoided problems that certainly would have occurred with the plan presented by your competition. I took careful notice of the reviews on Angie's List, and call some of the references, which were supportive. Finally, I chose Johns as a company that had been in business for some time and had extensive experience installing the basement waterproofing system. The guarantee was an extremely important factor in my decision, and John's track record suggests that it will remain in business and stand by the guarantee should problems occur. This was the best part of the project. Delfino and his crew (Francisco, Aaron, Ceasar) worked incredibly hard, were polite and considerate, and provided what appears to be a good installation. I give them my strongest recommendation. How they managed to hand carry 6 yards of broken concrete up out of that basement in the time they did is beyond me. John's employees spoke highly of the company, and the benefits offered. It sounds like a well run business. Please note that the system was installed in Central Oregon at our second home on the Deschutes River, where we are dealing with a high water table issue in summer. As of this writing, the water table is nearing its summer level, the sump pumps are working, and the basement/crawl space is dry.
