Why It Matters
Hot attics, gaps around building materials, and uneven insulation can make indoor spaces harder to cool. However, the best approach depends on your building and how it handles heat and airflow.
Helps Control Air Leaks
In suitable areas, spray foam and other air sealing measures can reduce unwanted air movement. Results depend on the product, location, and installation.
Supports Energy Efficiency
Good insulation helps limit heat transfer. As a result, a properly designed upgrade may reduce energy waste, although savings differ by property.
Matches the Building
Some closed-cell spray foam products can add rigidity in approved applications. Still, structural benefits must not replace an engineered design.
Requires Moisture Planning
Every building needs an appropriate moisture strategy. Therefore, we review product suitability and ventilation needs rather than promising a mold-proof barrier.
Works With Your Cooling System
Reducing unwanted heat flow can help support more stable temperatures. Your HVAC system, ductwork, and other building features also affect comfort.
Designed for Long-Term Performance
Material performance and service life depend on the product, conditions, and correct installation. We discuss suitable choices before work begins.

2/9/26: Tightseal’s techs were wonderful. Two guys showed up within the allotted time, set down the plastic to protect the protect, and were done in under an hour. They swept up the small amount of insulation that escaped the plastic AND they swept up the little pieces that escaped their truck.
I was less happy w/ the communication timeline from the sales guy, but not enough to lessen the rating. The crux of my disappointment was that it took 16 days & 3 e-mails/texts to get the pictures the techs took. The tech did ask if I wanted to see the pictures before they left, but I expected they would be sent w/ the invoice (they weren’t). Lesson? If you want the pictures quickly, get it from the techs. 🙂
Anyhoo, after 20 yrs of settling, our attic insulation was only at 8″ (high R20 rating). We finally decided to get it upgraded to current recommendations (18″, approx. R60). Through the experience, I learned the R-rating isn’t about better materials (as I thought), it’s all about the depth of the insulation.
The a/c company who quoted us for the upgrade chose Tightseal, and 3 mos later, when we finally decided to spend the money, we were able to get an appointment quickly. The guys were cool with me taking pictures while they worked, both were friendly, and as I said, in and out quickly. The one up in the attic even offered to sweep up the salt from the bag we used to prop open the door. 🙂
I would recommend Tightseal. Now … we wait & see how it impacts our energy bill now that the scorching, brutal, AZ summer heat is upon us. LOL!

Really happy with the insulation work. They took their time, didn’t cut corners, and cleaned up after themselves. Solid quality all around.

Tight Seal recently sprayed the exterior walls, ceiling, and garage of my new build home, and they did an outstanding job. The team on-site was professional, pleasant to work with, and took great care in their work. They were meticulous about taping off areas to prevent overspray and did a thorough cleanup afterward. I highly recommend Tight Seal for anyone looking for quality insulation work!
