TerraFirma was able to schedule everything to my convenience. from the appointment to installation, we were never pressed for time and felt like we were going out of our way to be available. They made sure to be available for us. They are Portland's household name for foundations. We turned our rather large sized basement into a bonus room for guests, the kids, etc. It is what I would consider a daylight basement and we are so excited that we now get to take advantage of this large space. It nearly doubled our square footage.
