Spray Foam Insulation in West Covina, CA

Top quality job by top quality workers. Highly recommend

We hired Air Tight Insulation to address serious energy loss in our West Covina home, and the experience was outstanding. Their team used a blower door test to scientifically pinpoint where our home was leaking air. The sealing work they performed was incredibly meticulous—around windows, doors, attic hatches, and all penetrations. The crew was professional, clean, and thorough. Our home now feels solid, quiet, and maintains a perfect temperature. This is true building science expertise.

The name says it all. We had an older home with constant drafts and dust. Air Tight Insulation of West Covina identified that our attic and crawlspace were essentially open to the outside. Their comprehensive air sealing process has been transformative. Not only is the house dramatically more comfortable and energy-efficient, but the indoor air quality has improved with less outside dust and pollen getting in. The crew was respectful, knowledgeable, and left everything spotless. Exceptional results.

These guys are the best at what they do. They provide a great service, professional install, cleanliness and great attitude. Kevin and Josh are great to work with and are willing to help you with anything you need. I've used them on big warehouse jobs (500,000sf +) & smaller warehouse spaces (250,000sf & below) installing scrim foil. They also offer insulation installs for any type of application needed (walls, ceilings, roof deck, etc.). Doesn't matter if the job is big or small, you will get the same great service either way! You give these guys a set of plans and they will know exactly what you need. If plans aren't available they will be more than happy to walk a job-site / space with you. I highly recommend this company for any scrim foil & insulation needs.

Good
