I want to express my greatest thanks for the excellent roofing, siding replacement, ADA hand rail, and concrete work you performed. Kaiser Permanente and PG&E were very pleased with your work. The planning and execution of the job was very evident and the workmanship cannot be matched. I have and will continue to recommend Airtight Construction.
