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."

"He showed up and everything sounded great. Lots of promises and nothing followed through. I paid for a white vinyl fence. Apparently his supplier ordered wrong color and they wouldn’t reorder because the pricing went up. So he came asking for more money to fix their screw up. He tried to pawn off that brown vinyl fence and we refused. Here we are 3+yrs later and still no fence or money."

The average cost of a paver patio is around $3,800 for a standard, 280-square-foot patio, but prices commonly range from $2,400 up to $7,000, depending on the size, the type of paver you choose, and any add-ons you opt for. The design and shape of your patio can also increase labor costs if your patio installer needs to cut curves in pavers or spend time arranging them in a specific pattern. Some additional costs to consider include site preparation and excavation, as well as additional materials, like concrete, crushed gravel, and drainage equipment.
Concrete repair costs range anywhere from about $0.10 to $0.15 per linear foot to fill minor cracks, to about $6 to $14 per square foot to replace damaged concrete slabs. Repair costs vary widely depending on the size and type of work needed. For example, replacing 100 square feet of driveway will cost between $600 to $1,400, on average.
The average cost of stamped concrete is around $12 per square foot, but you might pay anywhere from $8 to $28 per square foot. The average 12-foot by 12-foot patio costs $1,730 on average. Your exact pricing will depend on the patio’s square footage, the condition of the area where you want to pour the concrete, the desired stamp pattern, concrete coloring, concrete grade, and local labor prices. Don’t forget to budget for extra costs like land preparation and additional concrete fortifications if necessary.
The average cost to enclose a patio to create a sunroom is around $5,000, and prices generally range from $3,000 up to $10,000. The price you pay will depend on the state of your patio and whether it needs repairs or additional structural support, the quality of the materials you choose, the size of your patio, and whether you plan to run utilities into and finish the sunroom. The price for a fully finished patio enclosure could run up to around $20,000, while you might pay just $2,500 for a screened-in porch.
In almost all cases, you will need permits if you plan on building a sunroom over your patio, but regulations and requirements will depend on your municipality. Permits to enclose your patio will usually cost between $300 and $1,000. Since navigating local building codes and zoning requirements is challenging—and the consequences of not following them can be extremely expensive—we strongly recommend hiring a sunroom builder to complete the work and pull the permits for you.
