Your Home faces Water Damage

1. 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. Flooding is a serious concern.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. When heavy rains hit your region in Oregon, your basement is most likely to be the area that suffers the most from with water seepage problems. As an entire floor of extra space in your home, your basement is likely the largest single space in your home. If you allow this entire floor of space to be wet, moldy, humid, smelly, and unhealthy, you surrender this space as unusable

    Customer Testimonial

              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.

    Matt B. of Redmond, OR

    Customer Testimonial

              We used John's Waterproofing to waterproof our basement. They put in a drainage channel around the perimeter of the basement and they put in a sump pump with a battery backup. They put in an air dehumidifier and put up whitewall sheeting on the walls. It was excellent. They did most of it in one day. They were very professional and very clean. They made sure that nothing was damaged. They broke up a lot of the concrete so there was a lot of dust and they made sure they ventilated the basement. They didn't get any dust in the house. They took a lot of time to show me how to operate the sump pump and the dehumidifier. We don’t know if it was a lot or a little to pay.

    Robin D. of Trout Lake , WA

    Customer Testimonial

              Kevin designed a great waterproofing system and we are very happy with the results. Typically when it would rain hard for 2 to 3 days at a time, water starts to seep through the bottom of our daylight basement walls. There are some cracks in the foundation and when it rains really hard, the water sometimes seeps up through those as well. I am confident in the products and the design to keep my basement dry all the time.

    Stephanie K. of Welches, OR

    Customer Testimonial

              I had researched french drains due to a problem area in our driveway that was compromising our garages, garage doors, and cuasing an infestation of mosquitoes. My research led me to your companies website and information. I was thrilled that you offered free estimates, so I promptly phoned. Patrick arrived and I pointed out the puddle in the driveway and he quickly stated that your company no longer did french drains. I told him I was very disappointed for that was the main reason for the appointment. We proceeded to the basement, where I let him know my husband was going to install a sump pump and we spoke in length about your company's services and our prior dilemmas due to recent water damage. Patrick was gracious and so personable as well as so confident in your companies services that I started thinking that maybe we could hire your company to install a sump pump instead of a home spun job. Patrick sold your company so completely that I wrangled my husband into the notion that a professional team sounded like the direction we should go. Patrick also said maybe you could also do the french drain as a courtesy (paid of course) since you would be doing the sump pump anyway. Patrick left me with lots of brochures and high hopes as well as the promise to come back with another professional to look at our french drain situation etc. The day of the install the friendly team arrived and went over the approach of the job at hand. The work was underway and I realized that the placement of the french drain seemed off. Everyone once again graciously talked with me and unfortunately the scratch in the concrete of 25ft had been laid and I was assured that the low spot had been addressed. I had a knot in my stomach and after interrupting the progress two or three times, I decided they were the professionals and they were solving our problem, so let them work. The reason for my lengthly letter is to let you kow how much I appreciate your efforts and company as a team. We had several issues come up in which fell on the shoulders of your company. I want to again let you know how professional and hard workinig I saw your company consistently be, even when approached on the spot and after a hard couple of days. I would recommend our company to anyone with great pride. Your ability to remain professional with out excuses and with a problem-solving attitude and quality of people and workmanship is I am sure what has made you successful. I hope my project would not stop you from creative solutions for another family in the future. My husband and I have been in the design/build business for our whole careers and feel confident in our observation of this situation as a success. Please accept my respectful appreciation of your company and specifically; Patrick, Levi, Chad, Kyle, Greg and the front desk for taking my call!

    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.
