New Home at Hunziker

Like the hermit crab out-grows its shell, TerraFirma needs a bigger space to call home. Our goals are not the only thing that have grown since 2013. Our skills, our ambitions and our employees have also grown, and we need a larger office space to accommodate. We found our new home on Hunziker St. Tigard, OR 97223. Come and see for yourself!

Roseburg, OR - February 18, 2014

We can announce, finally, that Terrafirma is moving our Portland office. After a long and seemingly endless search for the ideal location and size for our new building, the search has come to close, and the preparation for new settlement has started. Moving will begin March 1st, 2014 and should be totally complete by April 1st, 2014 due to a few slight modifications and adding some personal touches to give it that TerraFirma feel.

The new office is located at 7910 SW Hunziker St, Tigard, OR 97223. Feel encouraged to stop by, check out our new space and learn about TerraFirma, what we do and how we can help with any residential or commercial foundation stabilization, earthquake retrofit, basement waterproofing, crawl space encapsulation or slab leveling projects. We are more than happy to educate and help with all types of projects. Foundation Problems? We can fix em'. We are TerraFirma Foundation Systems.

2014 is off and running and we are running right along with it, and we're excited for what challenges may come our way this year. We have a great group of guys on all levels. You'll find nothing but professionalism and friendliness from every one of our 64 employees starting with our Customer Service Representative who will help schedule your free estimate, to our Service and follow up team to make sure you are 100% satisfied. Our mission is to continue to lead the industry and to WOW the customer every step of the way, I believe we do that, and we're only getting better.
