We live in West Linn and every house in our neighborhood has issues with water in their crawl space from springs.

very professional and reliable from the office person to the estimator and to the lead man,…read moreSchyler. All were very good and the job was completed and on time.

Living in a 30-year-old home for the past two decades we've had several phases of upgrades, but one…read morething has always been absent from a 10x10 slab on our back porch: a hot tub. So, this summer, we decided to move forward with the plan to be "soakin' for the holidays" three months away. The only thing standing in the way of that dream: the slab and its neighbor had sunk a few extra degrees, roughly three inches, at the far edge. We were going to need to shore up and permanently stabilize this slab if our hopes of the (3-ton when filled) tub were going to materialize. I made a quick call to Terra Firma and they had an estimator out within a few days. The pricing was reasonable and had the standard 50% up front 50% when complete-type contract. Casey arrived spot-on at 8:00am yesterday morning and began doing his magic (the process involves boring 1/2" holes through the slab, then using high pressure and heat to inject a molten expanding foam under the slab.) The foam is rated to support about 5 tons (10,000 pounds) per pound of foam material, and....100 pounds later that whole slab is back to following the prescribed slope perfectly, raising almost three inches on the sunken side. He did a great job and was a great rep for the company, explaining what little was left to explain. He kept me up on the status of the (4-hour) job as he went along--because our slabs had previously cracked, he had to gently lift it up in small sections so as to not have the sections separate further. Perfect job. 24 hours later and the patched holes have dried to almost-invisible (see photos). Unless you know what you're looking for, you can't even really see that repairs were made. Now I just need to fill in the pre-existing cracks with concrete patching caulk and we're ready to schedule the hot tub delivery! Yippee! Thanks Terra Firma!

While the price did go up once the contractors arrived and did their own inspection (this was…read moreduring an active Portland flood period so leakage was far more noticeable than when sales person inspected), Avori and his team where wonderful! Avori was very proactive in addressing the severeness of our crawlspace leak. The Portland flooding and our non-functioning French drain made it really bad, allowing water to literally flood into our crawlspace! Avori and his team worked through the water and mud, installing new posts and beams, redirecting the water to a newly installed sump pump. The job took much longer than originally anticipated but was done well and our foundation is now much more stable. I really would have given five stars if the original quote caught everything but it wasn't flooding when the sales guy, John, came out so he didn't see the extent of our foundation issues. Avori was able to keep the increase to a minimum and we really appreciated all he did for us.

I hired John's Waterproofing to waterproof a corner of our basement…read more In this corner there was the only bathroom of our basement apartment that we rent out. John's told us that the toilet would always be available and the that the rest of bathroom would be put back together within a week. They never were able to get the toilet functional. John's plumber had some problem that didn't allow him to drive. Thus, the apprentice did all the driving. A combination of life issues between the plumber, the apprentice and poor scheduling and planning on the part of the John's made it so that the toilet was still not working after almost two months. I finally have John's one last attempt to install the toilet telling them "If you can't get the toilet working by Monday evening, I'll have to hire someone else to install it". Once again, a scheduling issue kept them from being able to install the toilet. I called another plumber that night and had a functional toilet by noon the next day. The new plumber was then able to finish the rest of the work the John's was supposed to do by the end of the next day. Even worse, it turns out that John's prior attempts at work had dumped concrete into our watermain. It cost extra work to clean that mess out. I strongly urge you to stay away from John's Waterproofing.

I haven't used Better Basements and Waterproofing yet, however, that's because they were honest…read moreduring the inspection and told me I didn't need to use them! I had a sketchy company do work on my crawlspace a few years ago and they've since fallen off the face of the earth. I was nervous to have a new company come out and 1) find something wrong and 2) try to sell me on things I didn't need. Michael H. with Better Basements and Waterproofing was honest - what was done by the former company wasn't up to his standards, however, it's fine for now and we can probably wait a few years before having any work done again. He also said we could use Better Basements and Waterproofing for sump pump maintenance (since we can't use the original company), however, he reassured me there isn't a binding yearly contract and I can just call if I'm interested (no need to agree this moment). I appreciated how honest and thorough he was in his inspection and in his explanations of everything. I've had a lot of companies over the years try to sell me on things I don't actually need. Michael didn't, and because of that, I actually will probably use Better Basements and Waterproofing in the future if I do need work done.

The company responded quickly and efficiently to my request to address the vibration caused by the…read moresump pump at my property. The technician provided a thorough assessment report with several options for me to consider, which I really appreciated. On the day of construction, the team completed the work quietly and professionally. I'm very glad to have found them and look forward to working with them as my long-term crawl space service provider.
