Premium Injection Foam Insulation
Fills the closed wall cavities of an existing home without tearing out drywall or siding.
Premium Injection Foam
What it is, and when it is the right call
Most homes built before the mid-1980s have wall cavities that are either empty or packed with fiberglass batts that have slumped, leaving gaps at the top of every stud bay. Injection foam solves that without a gut renovation. We open small access points, inject the foam, and it expands to fill the cavity completely, around wiring and plumbing, into the corners batts never reach.
What you get
Superior thermal performance
Injection foam delivers a higher R-value per inch than the loose fill or batts it replaces, and because it fills the cavity completely there are no bypasses for heat to move through. The wall performs at its rated value instead of its installed value, and in an older house those two numbers are usually far apart.
Effective air sealing
Air movement through walls carries far more energy than conduction does. The foam expands into every gap, seam and penetration in the cavity, so the wall stops acting like a filter. Drafts at outlets and baseboards on windy days are the symptom this fixes.
Installed without a renovation
Access points are small. They go through the siding or the interior wall depending on the construction, and they are patched when we finish. Most homes are done in a day. You keep your drywall, your trim and your paint.
Moisture resistance
The foam is vapor permeable, so the wall assembly can still dry. It does not absorb water and hold it against the framing the way wet cellulose can, and it will not become a food source for mold.
Quieter rooms
A filled cavity is a poor sound path. Road noise, neighbors and wind all drop noticeably, which is the benefit homeowners mention most often after the first week.

Injection Foam vs Spray Foam
Injection foam goes into finished walls without demolition. Spray foam needs open framing. A straight comparison of where each one belongs and what each one costs.

Frequently asked questions
Do you have to remove my drywall or siding?
No. We open small access points, inject the foam, and patch them when the work is finished. The interior of your home stays intact.
How long does injection foam take to install?
Most single-family homes are completed in one day. Larger or more complex homes may take two. You get the timeline in your written estimate before any work starts.
Can injection foam go into walls that already have insulation?
Usually yes. Older fiberglass and loose fill compress and settle, leaving voids the foam can fill. We inspect the cavity first and tell you what is actually in there before we quote the job.
Is injection foam safe once it is cured?
Yes. It cures in place and is inert once set. Our installers follow the manufacturer handling and ventilation requirements during installation.
