About This Service
Wall insulation is one of the most effective ways to improve year-round comfort and reduce your energy bills, especially in homes built before modern codes.
We use dense-pack cellulose or blown-in fiberglass to fill cavities behind siding or drywall. This method reduces drafts, noise, and heat loss, all without disrupting your home’s finish.
The result: a more efficient, peaceful, and consistently comfortable living space.
Frequently Asked Questions
Are there rebates available?
Yes, many homes qualify for wall insulation incentives from utility programs like PEPCO, BGE, or SMECO. We’ll help you access every opportunity.
How do you add insulation to existing walls?
We use dense pack cellulose or blown-in fiberglass, installed through small holes drilled in drywall or siding. This method fills cavities without tearing down walls.
Why insulate my walls?
Wall insulation helps regulate indoor temperature, reduces noise, eliminates drafts, and lowers energy bills by limiting heat transfer.
Will this damage my home’s interior?
No, our process is non-invasive. We drill small access points, install insulation, and patch everything cleanly when finished.
