Job Stories From Columbia County, OR
Four Steps to Moisture Management and Air Conditioning Deer Island, OR

    For home owners that want to get the most out of their home including healthier air, lower energy costs and more comfortable living conditions, there is one place to start looking, in the crawl space. Home owner Tim J. of Deer Island, OR had the same thought that many Oregon and Washington home owners do with home efficiency. After being recommended by his friends and neighbors, Tim called TerraFirma and scheduled a free estimate.

    The four steps to crawl space encapsulation are simple but effective. Stop ground water seepage. Un-couple the earth from the house. Condition the air. Block the vents/encapsulate the area. Two things to remember when making your final decision are, is my installer the highest qualified for the project and do these products provide and durable, long lasting solution? Remember, some solutions are better than others.

Office Space Crawl Space Repair Rainier, OR

    Mold and moisture problems are not limited to just your home. Commercial units, civic buildings and office spaces are just as vulnerable to these issues. In Rainier, OR, just along the Columbia River border, two side by side office spaces were experiencing similar moisture and mold issues. Sheryl T. owns both units and works out of one of them. Sheryl's main goal is to eliminate water seepage and clean the air circulating through the office space. After seeing a commercial on tv, Sheryl called TerraFirma for a free inspection.

    Under these units, the basement area and the crawl space area are continuous. It also changes from a cement slab to dirt floor. It is very important that we keep the waterproofing system continuous as well in order to ensure we collect all water and safely remove it from the area. Waterguard was installed around the perimeter of the area along with Cleanspace wall liner. These two systems, working in unison, provide the proper water protection needed to keep the area dry all the time. Through the installation of a TripleSafe sump pump, all water is safely removed from the space. By managing moisture levels, mold was kept at bay and healthier air is now circulating through the units.

    With two simple systems we achieved both of Sheryl's goals which she won't have to worry about again.
