"We had Plantrex do a deck resurfaced. After it was in, there was a tenant caused deck fire. Plantrex did an outstanding job on both the original resurface and on the deck repair and restoration after the fire. Cleanup, everything was great."

"Focused on your Satisfaction"-For over 21 years, Communication and Professionalism have been our top priorities. Consistently working hard to make your remodeling project a pleasant experience.

"Overall a good experience. We hired ACS to take down and rebuild a brick pillar supporting our front porch. Gary's crew was excellent. Although they only spoke Spanish they were helpful and did a good job communicating as much as they could about what they were doing and/or had done. We're very happy with the end product. Gary stayed true to his quote and the contract price. The project was more involved than I expected, but they came through and completed it on budget. My only complaint is that Gary was hard to get a hold of at times."

We offer the experience of hundreds of retrofit installations, along with the highest quality products, valuable design and engineering, and stellar results.

"Matt and the Evergreen Seismic team were communicative, honest, and collaborative throughout our retrofit. When I reached out initially, he helped me learn about the retrofit process, and even encouraged me to consider doing it myself. I really appreciated that — it'd be so easy for a professional in his position to scare a client into getting the work done, but he did the opposite. He also gave us a competitive quote, and offered to match any other we got elsewhere. I ultimately decided to hire him, and was glad I did. He and his team got the work done in a timely and orderly fashion. Our foundation turned out to be a little unusual, which took more time than anticipated, but he walked us through what they were doing to accommodate the difference, and did not ask for an additional fee for the extra time spent. They handled all the city permitting and mailed us the paperwork to keep on file."
