New Leaf completed a thorough inspection (they were actually sent by the seller), provided a fair bid, and were gracious enough to offer a payment plan. When they came to do the work over the course of three days, they were hard working and cleaned up after themselves. One of my favorite things, though, was overhearing someone telling the group these encouraging things like "diamonds are made from pressure!" Just thought that a company that supported their people was a company everyone should support. Our HVAC contractor was also super impressed with them! Would 1000% hire again. I swear our house immediately got warmer because of the insulation!

Overall, the office communication, speed of delivery, pricing, and customer service was A1. Will be using them from now on.

After this unexpected remodel and damage was exposed we had a delay of several months to get on their schedule. When the project date arrived, they showed up on time, cleaned well after the demolition/addition of interior floors to allow drainage and a sump-pump. My original review (4 star due to not adjusting the cost when less product was used) they owned the mistake and recognized their communication gaps. I do appreciate that attention and feel more confident in the company. I look forward to many years of DRY basement/master bedroom living.

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!

Seth and his team evaluated our situation and knew what to do, based on their extensive experience with similar issues in Vancouver. The situation was caused by careless, even incompetent contractors who have been allowed to do this kind of thing all over Vancouver. In a little over two days, with the initial work done during heavy rain, they got rid of the leftover organic material, put back good soil, tamped it down into a gentle slope. Then they smoothed it all out and seeded the area and where they had to access through the front yard. Our grass has begun coming up but of course, with the winter it won't be in until spring. The cost was reasonable and fair and I would hire them again in a minute. I highly recommend Seth and his team if you have any excavation needs.

We had a full excavation of our basement perimeter to waterproof the exterior. Interior sump pump solutions didn't gel with me at all and I was glad to find a Portland company that didn't want to take the easy option. I really cannot say enough about Byron and his team. They didn't just meet my expectations. That went that little bit further. Good job team and thank you!!! If your looking to have Byron and his team conduct any form of work for you. Please do so with confidence.

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.

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.
