"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"This team arrived for work in the morning, and was complete by lunch. Outside wall repairs on MidCentury Modern, and full assessment to bring house up to modern seismic codes. Great feedback to close out, plus a solid warranty. These folks specialize in crawl space homes and keeping them solid."

"Overall the job took the better part of a week and from our perspective was a success. Ryan worked with us in selecting
the right color for the stain. He carefully removed and replaced the numerous potted plants we had on the deck and left
the work area in a clean condition. The patio and balcony look great and our only regret is that we didn't do it earlier."

"We met with several companies before deciding to go with Palm Construction and we are very happy we chose them. Omri and his team were on time, professional and gave us a great price. They replaced our roof in less time than we even hoped! We are so impressed with the quality of work they did and for a good price! We highly recommend them!"
