This company really stands behind their work. During the winter season after we did our…read morewaterproofing project, we discovered there were a few areas of our deck that weren't draining properly. We were really impressed by how Rock Solid handled it. Last week, a year after the original project, they sent out a crew to resurface, reslope, retexture and recolor the deck. They really demonstrated a high level of accountability and integrity. Not all contractors would have done this. We're very pleased with our experience. We've had a chance to meet many of their team members. This time, Devin brought Hannah, Spencer and Brody. They were all really hard working, and demonstrated a very quality conscious attitude. Our experience was that they really want the customer to be happy. We were grateful for their efforts. There are many different ways that a company can handle a situation where something goes wrong. Rock Solid really hit the ball out of the park on this one. They were really great to work with. 5 Stars!

I contacted several waterproofing companies, all of whom sent out estimators. I found Mikael of Rock Solid to be very personable. He took all the Covid precautions and got a bid back to us within a few days. It was much better value than that of his competitors. The office called to schedule the work and it was done within two days. All the workers were pleasant and efficient, and the team leader even returned at the end of the second day to repair something his team had neglected to finish--much to my surprise, as I hadn't seen anything amiss. They left the work site very clean. The proof of their work is that during the heavy rains of the past few days, the basement is as dry as a bone! I would highly recommend this company if you have recurrent problems with basement leaks.

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!

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.
