"Our house is almost 130 years old, so we needed to have some foundation stabilization done. The company was a pleasure to do business with. From our initial consultation and beyond, every contact was courteous and knowledgeable. On the first day of the project, after removing the dirt to see the foundation, it was discovered that the existing foundation was not sufficient to support using the helical piers according to the building inspector. The dirt was all replaced and it was arranged to come back out and give me a quote for a different process using smart jacks. Due to circumstances at my local building department, the new job had to be postponed until a new permit could be obtained. Once that was done I was rescheduled and the job was completed in a day and a half. When the building inspector came to sign off on the permit, he raved at what a great job they had done. I would definitely recommend them to anyone who asked."

"I contacted Foundations First NorthWest and a couple of other contractors when an inspection revealed some foundation settling and crawl space damage. I chose Foundations First to make the repairs because they included more work, and at a lower price, than their competitors. I can't say enough about how professional everyone at Foundations First NorthWest was, from the first meeting with the sales rep to the constant communication with office staff throughout the project. Every step was completed without a hitch -- getting permits, engineering, the repair work and county inspections. The work crews worked quickly and efficiently on both the installation of stabilizing foundation piers, and also on the crawl space repairs. And they left the work areas in a very clean condition. I highly recommend Foundations First!"

"I recently hired TerraFirma to raise my house several inches and level out my basement floor. Working with TerraFirma Foundations was a great experience, from start to finish. Everyone involved in the project was very friendly and professional. I was kept in the loop, as to what was happening, every step of the way. I would definitely recommend this group to anyone needing help with their foundation."

"Spot on! Wife was extremely happy that the crew came in and performed all work in the time estimate given. Very clean and professional. Expensive, but I had insulation that needed replacement, prior rodent infestation, and drainage issues. All now clean!"

"First visit: Ryan came to see what work would be needed. Gave recommendation for water heater as well as 'booster' to provide more hot water. Did not go into crawl space under house to investigate bathtub plumbing needs. Explained steps we needed to take to prepare bathroom and floor for installation. (Total visit: almost an hour.) Second visit: Ryan performed jobs 2 and 3 easily and efficiently. Replaced earthquake straps on water heater; they had not been installed properly 10 years ago. Finally entered crawl space and realized he would need a second person to do plumbing bathtub hookup from below and above floor at same time. Arranged for a 3rd visit with an apprentice a week later. Third visit: Ryan and helper cut waste line and installed branch line to new tub location, plus install new water supply lines for tub as well as hook up tub to new branch line. Worked efficiently and thoroughly. [NOT MP Plumbing's fault: hose bib had hidden damage which began leaking a few days later; Seth called and explained function and design of hose bib, but when he was informed that it was still dripping at end of explanation, he immediately said something was wrong and he'd be by in 20 minutes. Arrived quickly (forth visit), removed part and discovered mis-manufactured part. Replaced immediately, and made note that it was too soon to have been our fault so there would be no charge for the part or the visit.] Ryan, Seth and apprentice were all very friendly; they took the time to make sure we understood what they would be doing (and in some instances why). They worked well and efficiently and were very careful and considerate of our space. Easy to talk to and we never felt they were talking down to us; when they used in-house 'lingo', they made sure we knew what was meant. Overall a very pleasant experience. While we had been told on the phone when we made the initial appointment that the first visit was a chargeable service call, Ryan discounted that first visit as he had not discovered the need for a second person and thus he had to come for the third visit with the apprentice. We felt that we were treated exceedingly fairly in those circumstances. Total cost includes water heater, booster and plumbing fittings."
