"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."

"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"

"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!"

"Before any work could be done, the entire duct system had to be removed. TerraFirma worked seamlessly with my HVAC contractor. There were no issues with the duct system installation after the retrofit and encapsulation."

"I researched 4 companies to fully encapsulate a crawlspace damaged by flooding and rats. I also did a lot of research into possibly doing it myself so i knew what to look for. John's was the most expensive, but they were all in the same general ballpark. I was put off by some of the competitors marking insulation as "extra" and not including in their initial estimate. Insulation is required! John's costs a bit more but you get more too: John's insulated the entire floor with wrapped foam pads, dug a drain trench around the entire perimeter, jacked up every concrete pier to slide vapor barrier underneath the posts, and used proper mechanical fasteners on all of the wall insulation boards. Every nook and cranny was sealed with spray foam. The workers were amazing. They did not cut any corners. They nipped and tucked every tight little spot and never complained or made excuses. They built a plastic clean-tunnel every day and took it down down every afternoon. They did not leave behind trash. My crawlspace is clean enough to literally eat off the floor now. I would recommend John's if you want your job done correctly."

"After inspecting our foundation earlier, Q determined that we needed a sump pump (which we suspected). His quote was reasonable compared to others we had heard about, so we went ahead with it.
His team of three guys worked hard for two days digging drainage trenches and installing the pump in a couple of feet of standing water. We then had to wait about a week for the water to pump out and to dry out so a new vapor barrier and gravel could be added. This was done during a cold winter where it took longer for the area to thaw and dry out so the delay was kind of a bummer, but not at all Ethereal's fault.
When they returned, they were able to finish up in one day (so three days of work total) and cleaned up after themselves very well. The guys were pleasant and happy to answer questions during the work and Q was careful to follow up and check on the work. All in all a great group to work with as long as you're realistic about the work necessary and time involved."

"From estimate to hire there was great communication. The price was a bit higher than other estimates but I'm glad I chose this company. They painted the fascia boards on my two-story multi-level home and did a great job."

"Western Construction Systems came out and did exceptional work at my house! They went above and beyond my expectations! They were friendly, professional, and hard-working! They took care of all the issues that I had concerns with and then some! Their prices were fair, especially for the high quality of work that they did! I know I pestered them with questions, but they were patient every single time. Before I contacted them to have the work done, I had high anxiety about the drainage issues. When they were finished, I felt confident that there were no more issues. Peace of mind is priceless!"
