Mike F. Mike F. SW Albertson Road

Our home is on a slope in the woods, and over time we noted significant signs of settlement - cracks in drywall and ceiling, the deck sinking, settlement of walkways and front step, cracks in foundation. Josh from TerraFirma came out and did a very thorough (at no cost to us) evaluation of the property, identifying the issues relating to the soil and location, and probably how the site was prepped originally, as well as problems related to water drainage down our driveway and dumping into the soil next to the foundation. He recommended placing push-piers to support and lift the foundation along 3 sides of the house, and adjustable jacks in certain areas of the crawlspace to lift some of the floors that were sagging. He also recommended having trench drains placed across the driveway in two places to eliminate the water draining down to the house (to be performed by different contractor). The sunken slabs/steps/sidewalks would be addressed by polyurethane foam injection under the slabs (subcontractor to TerraFirma). We also decided to have our crawlspace encapsulated at the same time. This was actually our idea to ask about that. Josh was very professional and answered all questions, and at no time did he come across as high pressure or with a sales pitch. He simply presented us with possible solutions to the problems.

In early November, the work began, taking about 2 weeks. Drew, the installation foreman, and his crew were great. Very cheerful, professional and courteous, and hardworking, despite having to work in absolutely miserable conditions of cold and rain. Drew was always available to answer my questions and address any concerns, and went the extra mile to do little things to tie up loose ends in the project rather than leaving things for us to have to deal with afterward.

There was a problem early on when cracks developed in the foundation where at least half the piers were placed, owing to there not having been any rebar reinforcement of the foundation (rebar not required code until after about '98) when it had been poured. Drew indicated that this was not uncommon and that the piers would still do the job. However, many of the cracks were along one edge of the brackets or next to them, where shear along the cracks might be expected during lifting or support. There was also one pier that was very tilted/angled where it contacted the foundation, that mechanically appeared unsound in that position. I called for a time-out and contacted the engineer, Rob, and he and the production manager Keith came out to assess the situation. This resulted in Rob revising the plans to include some additional piers and bolting steel plates on either side of a number of the cracks that were in question, to mitigate the problem, before the foundation was lifted. So they were very responsive to the concerns I raised, and did what was necessary to address the issues. And I should also point out that we were NOT charged anything extra for the additional work performed - only the amount agreed upon in the original contract. There is a small part of me that wonders to what degree the cracks, etc would have been addressed had I not brought up the issue, but I'd like to give TerraFirma and the engineering company the benefit of the doubt and assume that the outcome would be the same (i.e., that the cracks would have been plated, etc). I was slightly disappointed that the cracks in the drywall and ceiling didn't seem to improve much or at all after the foundation was leveled, and I still have some minor concerns about support along one corner, but overall we're very pleased with the job. Drew grouted all the cracks, and repaired all the storm drain pipes, even including a pipe for the irrigation system that I had assumed I would have to fix myself. Another feature to point out that helped make our decision to forge ahead with the project was the 75 year transferable warranty, and the fact that anytime within the first 5 years, you can have TerraFirma come back out to reassess the leveling at no charge.

Another bright point was the concrete leveling job performed by Geoff - he and his asst were very accommodating in scheduling, and did a great job of lifting and leveling the sidewalks, slabs and step.

TerraFirma really does seem to be perfectly suited to doing this sort of work on residential homes with difficult/limited access to the foundation, and we certainly would recommend them to anyone with foundation issues. Next summer, we plan on replacing our old deck, which continues and will continue to sink for all the same reasons that the foundation had been sinking. But this time we will support the deck with helical piers, and we are planning to have TerraFirma place the piers.

I would have preferred a one total price for a single phase for the stabilization of my home. Not pillars inside and then later the outside repair. Cost was very high. More reasonable price would be preferred.

Monica K. Monica K.

I just want to say again how much we appreciated the work that was done here. The crew worked so hard and such long hours every day and were always friendly and respectful to me. The excavations were done carefully and the yard/foundation areas were completely cleaned up when the job was done. Any questions or concerns I had during this process were quickly answered and I was always shown what was happening as the work proceeded.

I wanted all the guys who worked here to know how much their time and efforts were appreciated. Thank them for me.

-Robin and Monica.

Very smoothly handled process. Messy, dirty work but we would never have known it from the care the crews took to keep the adjacent basement site clean and useable while they were mucking about in the crawl space!

5.0/5
Grant K. Grant K. SW Viewmont Drive

Our job had some unforeseen complications because of the way the foundation was constructed. The Terra Firma team has been good about coming back several times to address problem areas.

The only downside is that this foundation construction problem was noticed during the initial installation, but nothing was mentioned at the time and the install proceeded as planned. Very soon after, we had many water leaks appear because of that problem. We know it was an unusual circumstance, but it was a little concerning that it wasn't recognized as an issue during the installation and nothing was mentioned. Homeowners like us rely on your knowledge and problem-solving ability, so this was a bit of a misstep in our opinion. But, the company has been good about taking care of the problem since, so we still feel very positive about the experience.

Overall, everyone we have encountered either in person or over the phone has been great. It seems like a company that is well run and has it's act together.

David G. David G. NW Brooks Rd

There were two parts: the basement waterproofing and the porch lifting. A young, minimally experienced crew was sent for the waterproofing. The Waterguard system we were expecting couldn't be installed and a surface-mount DryTrak was substituted. The sump pump basket wouldn't fit and had to be cut down by hand. Despite good intentions a water pipe was broken and the basement was flooded. There had been no preparation for cleanup of such a complication - no towels, no mop. For the porch lifting a single young man was sent and appeared adequately experienced. That process was performed flawlessly and without a hitch.

Scott H. Scott H. Portland, OR

I was very pleased with Don, the representative who came to evaluate a crumbling exterior wall in the basement of our 1927 house. He was extremely knowledgeable and honest and diagnosed the problem, but concluded the repair was a fairly easy fix that Terrafirma did not do. He did not push or high pressure any expensive solutions, and I appreciated that. It was not about sales above all else but about helping determine the cause of the problem even if Terrafirma could not make a sale.

Allan, Luethe Allan, Luethe NW Skyline Blvd

You have an ace in Ryan Lahley. He is an outstanding young man. Treat him well! From the minute I contacted your company to the signing of the contract I was treated very well. I feel totally comfortable having TerraFirma take on my project. I like having the materials sent our ahead of time. The extra information was very helpful.

Job Stories From Hillsboro, OR

Proper Crawl Space Systems Restore Health and Value to You and Your Home

During times in the northwest when it just doesn't seem to stop raining (which is somewhere between 8 and 9 months of the year), do you every worry that your crawl space or basement is improperly waterproofed and water is seeping into your home? A little water won't hurt, but a lot can be detrimental to you, your family and your home's overall health.

Chris A. from Hillsboro, Oregon was experiencing some leakage in the crawl space and is concerned about the long term affects it might have. As this trend continues, you get standing water in the crawl space, which can lead to high levels of humidity and temperature. This will not only rot away at the wooden beams under your home, but can also lead to mold development which become airborne and breathed in by you and your family.

Chris did the right thing and didn't hesitate to call us for help. By installing an effective drainage system leading to a sump pump for removal and a new 10ml vapor barrier, Chris can now be worry free that he is keeping the family healthy and restoring the value and health to the home.
