"I took a chance with CSZ construction because Home Advisor reviewers were so positive-- and I am glad I did. Cesar, the owner, is a very competent professional who did most of the work himself. He weatherproofed my balcony door, fixed a window and replaced the water line of my refrigerator. His prices are very competitive and he will be my go-to repairman from now on."

"Jim and his crew worked on our house over a three week time period. They were always prompt and notified us of any change in the schedule due to weather. Opening the roof revealed extensive water damage which significantly added to the cost but Jim provided photos documenting the structural conditions and explained the rebuilding process and the materials needed. We are also pleased with the replacement windows and the finish work on both the interior and exterior. Jim's crew were exceptional. They worked non-stop and always left a clean work site."
