"Joe and his crew were professional, prompt, courteous and patient throughout the whole process. Communication was excellent. Petra the designer was very helpful in choosing a palette. They were attentive to all the details and wanted to ensure I was satisfied. Joe went the extra mile and coordinated with the contractor that did the seismic work that I had completed at the same time. There are likely lower priced siding contractors out there but the quality, integrity and ease with which it was to work with Joe and his crew was definitely worth it and the work was done right the first time! I absolutely would hire him again. Anne"

"Purchased a 1906 home in North Portland with an uneven foundation that had been patched for 60 years, but needed serious stabilization work. I contacted multiple foundation contractors in the greater-Portland area and Ram Jack was the only team that provided a full worse-case estimate that included everything that I may need to permanently stabilize the home's foundation. Other contractors' estimates were higher, omitted some of the features of Ram Jack's estimate, and involved greater excavation work around the home. While I was collecting estimates, I had multiple contractors check the levels on the house and could see the home was continuing to sink as much as half and inch in some areas within only a few months, so I knew I had to do something soon as the hotter summers are causing significant erosion to the clay soil in north portland. After paying the 50% down payment, I was quickly in touch with multiple project managers and structural engineers who were able to answer my questions as the work plan developed. I work from home and have two cats, so I was a bit worried about the noise and needing to leave at certain times during the work. Ramjack devised a plan of installing 12 helical piers from the basement and 2 outside for a small crawl space area as well as replacing most of the piers in the basement that had water damage. During the excavation and pier installation, I didn't have to leave my house at all, my cats were fine, none of the utilities ever needed to be turned off and none of the neighbors said they heard more than the hum of the generator outside; insane professionalism. The work team kept me informed at every step of the excavation and pier installation and was able to recover an inch of lift with only a few drywall cracks that I patched in a day. I could have gone further, but wanted to avoid any potential damage to the sewer pipes and stay within my budget. During the lifting, I was standing with the lead construction manager who kept me informed of every risk as we lifted the house bit by bit. During the excavation my basement looked insane with mounds of dirt everywhere, but the construction team cleaned everything flawlessly; all I had to do was a quick mop and the basement was good as new again. Overall had a great experience with RamJack; the 20 years in business shows, most everyone I dealt with had been working with them for years; the construction manager had been doing pier installation for 15 years. The work was expensive, but cheaper than the other local contractors, and certainly way cheaper than replacing the entire basement foundation. Ramjack was even able to take a few grand off the intitial worse-case estimate for solutions not needed. Glad I was able to repair my 120 year old home; here's to another 100 years. Big thanks to Pancho and Stephen, as well as the structural engineers and project managers; I'm very happy with the work."

"We recently expanded a deck, added a patio cover, and are putting a hot tub underneath this second floor deck. There was a concrete patio below the existing deck and we wanted to match that, w/ reinforcement for a hot tub. We got a couple bids for the job. Danny was the estimator that came out for Forest and he seemed knowledgeable and was punctual and professional. It was not the cheapest bid, but the company is much more well established than a couple others we consulted so I put more trust in their work. Rigo is the guy we needed to work with on scheduling etc. for concrete work. This was a little rocky at first, but that had a lot to do with us needing to postpone the start till our deck was done, but then also work around a vacation we'd be taking, and make sure the concrete had enough time to cure before our hot tub is dropped. Despite a slight language barrier, we worked it out and even managed to get it done ahead of when we originally scheduled it. Punctuality is impressive with these guys. For 3 days they were waiting outside our house to start at 7:30am precisely. They had to remove a portion of fence and work around some foliage for access. They ended up encountering an unexpected drainage tube of some kind while digging and made sure to create an access point for us if it's ever needed in the future. The concrete looks great and matches our old patio so well, it's hard to tell they weren't poured together. Danny and I (and later Rigo) discussed treating the old concrete to help the matching. At the end of the work they did a great job of cleaning up the area and returning everything to normal. Rigo also helped us by showing us how to remove the fence portion for when our hot tub is delivered and left the top cap off because he said we'd really struggle to get it off if they put it back. I'm happy with the work, communication, and cleanup and trust if there are any problems I will be able to get them resolved. If we have further landscape needs in the future I will def be calling Forest for a bid."

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."

Foundation Repair questions, answered by experts

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

Periodic sealing and cleaning to maintain appearance and integrity.

Concrete spalling can be fairly serious, especially if left untreated or in a public area. It can be a tripping hazard and, if not resolved, can lead to structural instability.
