Sam, his brother and his team were such a relief to a very stressful situation when I discovered…read moresome minor basement flooding issues during the winter 2022 rainstorm after moving into our new home. We quickly met with several waterproofing teams and got several quotes before we moved forward with Sam. Sam and his team were the only contractors that felt genuine, that felt confident about understanding what was going on in our basement and the only contractor that wasn't trying to sell us on the most expensive solution, but only working with us to find the right solution for the best value. Sam was always communicative, prompt, great at explaining the work and his team did a quick & thorough job. Would highly recommend New Vista to anyone in the Vancouver/Portland area needing waterproofing work done!

We were so thrilled to get Samuel and Christian and their team to help us in redoing our property drainage. They are like surgeons the way they trenched our new drainage paths and secured all of the new pipe fittings leading up to a new drywell. It poured rain for two days straight and they still had smiles on their face the entire time. They were so respectful of our existing plants, were incredibly tidy in a process that could otherwise be pretty muddy and messy, and a joy to have at our home. Their work was truly excellent and would highly recommend New Vista Construction. I'm almost excited for more May rain!

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!

Work completed before estimated completion date. On the 1 outdoor area, there was a retention stone wall, along with some other items requiring extra work to get to where they needed. After the work was done, it was all put back together and meticulously cleaned - you cannot tell that any work was done there; absolutely perfect! It was not easy to do what they did at that particular location. Value: Even though foundation repair/work is a costly service/installation; you certainly get what you pay for with Ram Jack West. I received more value than what I paid. You see, their value started 4 years ago, in 2022. I had them come out, define and price the job and signed a contract and paid 1/2 upfront. Within a couple weeks after signing I became critically ill, in the ICU and Hospital for 2 months. As a result I lost my job among other things and have a permanent disability. I reached out to Ram Jack West and they, very graciously, supported me by refunding my money immediately - especially at my greatest time of need. This is well above and beyond exceptional for a business and that is a huge factor as to why I called them back, in 2026, after I had stabalized, and got some money together. They re-bid the job, I expanded what I wanted to have done and they accomodated my requests. They helped me work out financing and walked me through the processes very thoroughly. The result was a delight from start to finish and all of it ended up being done well ahead of schedule. Truly class act! Thank you so much!
