Airtight Construction, Inc. is a premier construction company and general contractor in the San Francisco Bay Area with extensive experience in a wide range of services, including commercial concrete, asphalt, above grade and below grade waterproofing, ADA compliance, structural repairs, excavation, siding and stucco repair and installation, commercial roofing, 24-hour emergency repair services and virtually all other construction contractor services.
We have worked for decades with owners and managers of occupied commercial buildings, industrial manufacturing plants, and residential dwellings throughout the SF Bay Area and beyond. Headquartered in Concord, California, our fully equipped and professionally staffed organization can meet any construction, renovation, or retrofit need. We can serve as a single point of contact for the most complex and time-constrained projects.
We are committed to the responsive delivery of flawless craftsmanship and the industry’s best customer service for our many San Francisco Bay Area and Northern California clients. We bring proven expertise and time-tested techniques to every job. While most companies rely on subcontractors for major parts of their work, we do everything in house. This allows us to maintain tight control over quality and scheduling of the work performed. Our cleanup crews work daily to keep the job-site clean, safe, and usable at all times.
