TerraFirma Foundation Systems
TerraFirma Foundation Systems
Thousands of NW homeowners have trusted TerraFirma Foundation Systems to keep their homes safe, dry and stable since 2005. Nearly half of our business comes from referrals or repeat customers. We can help you too! TerraFirma is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

Bellos Construction
We pride our company on reliability, great communication, integrity, and quality work. We have 15 years of experience in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!
"We actually had Bellos Construction do considerably more than just a bathroom remodel. Additional work included installing flooring, installing insulation and drywall, demolition work, roofing repair, etc. Overall the experience was good. Jose is very responsive and helped me out quite a bit dealing with renovating and repairing an older house that was not properly taken care of by the previous owners/renters. The only real issue we had was confirming the materials that would be installed in the bathroom (i.e., fixtures, etc). There was some miscommunication there that probably was not helped by the fact we are out of state and trying to manage a construction project. One thing that stood out about Jose was his willingness to help out with things that didn't fall under his contractual obligations. For example, he helped me transport a water tank when he didn't need to do so. If we have a need for services that Bellos Construction offers, then we will definitely consider them in the future given our experiences with them."

Christie Architecture LLC
Thoughtful design for residential and small commercial projects in the Pacific Northwest.
"Lisa is a genius! With creativity and precision, she maximized every nook and cranny of our tiny 1906 cottage and brought it into the 21st century, while maintaining its original charm and character. Our "new" home is so much more functional now, and a delight to live and work in. Lisa took the lead on our projects (kitchen, bathroom, basement), but Adam is equally savvy. Both are fantastic listeners, brainstormers, collaborators, total professionals and all-around lovely human beings. We highly recommend Christie Architecture, and look forward to working with them again in the future!"

BAKER & SON CONSTRUCTION INC
BAKER & SON CONSTRUCTION INC
Baker & Son Construction has more than 45 years extensive experience in every aspect of building, developing, remodeling and reconstruction. We will get your job done on time and on budget. Our team has the highest standards and stand behind every detail in the construction process. Client trust, attention to detail and a commitment to excellence are our highest goals, and our customers have proved their trust over and over by giving us their return business and recommending us to their friends and family.
"The project was essentially a remodel of a circa 1950's beach cabin with a small addition. We chose Baker and Son on the recommendation of our neighbor who had used them to build a detached garage. Our plans were relatively simple at first: build the addition, expand the kitchen, build a new bathroom and create a new entry. As work was underway, it became clear through the advice of Baker and Son that our kitchen was too big and out of scale for the cabin. We ended up eliminating some walls and opening up the cabin in such a way that created one large room but still a separate kitchen, dining and living. It was a huge improvement to the original design. In addition to the interior work, Baker and Son completely overhauled the exterior which included new windows and siding. New structural headers were required because they didn't exist. Also, since the cabin is post and pier construction, they leveled and strengthen the existing structure. Work included new skirting as well. Their attention to detail was very impressive. They are masters at creative problem solving, patient, responsive and positive. They have a very strong sense of design. We were never pressured into quick decisions. The contract arrangement for our project was essentially time and material because formulating a bid on an old cabin remodel would involve too many unknowns. We agreed to a fair hourly rate and all material and subcontracted work we paid directly with no additional overhead or fee. This saved us money. Since we lived out of town, Baker and Son were so well connected with various vendors and subcontractors, it simplified making arrangements. Now that our project is complete, we are so excited about the end result! We would highly recommend using Baker and Son Construction for any project."
