Sustainable Insulation for Attics and Homes

Your home is more than a place to rest your head – it’s the heart of your family. It’s where the days begin, where memories end, and where comfort should not be compromised.

If your home was built before 2016, you’re likely losing valuable heating and cooling through walls, attics, and crawl spaces. This can put added strain on your heating and cooling systems, lead to uneven temperatures, persistent drafts, cold spots—and ultimately, higher energy bills and maintenance costs.

Our retrofit insulation services are designed to upgrade your home – while preserving the charm, craftsmanship, and character that makes it yours. We focus on sustainable materials and methods that reduce your home’s environmental footprint, improve indoor air quality, and enhance your home’s long-term durability.

Attic

Insulating your attic helps reduce energy waste and maintain consistent temperatures throughout your home.

Air Sealing

Closed-cell spray foam is used to seal gaps around plumbing, wiring, framing, and other common leak points throughout your home. This process prevents energy loss and improves indoor comfort by keeping conditioned air in and outdoor air out.

rim joist insulation

The rim joist area is a frequent source of air leakage and moisture intrusion. We apply closed-cell spray foam to insulate and seal rim joists, improving your home’s thermal efficiency while also deterring pests, sealing out moisture, and enhancing indoor air quality.

duct systems

Leaky ductwork can waste your heated or cooled air before it ever reaches your living space. Professionally seal your home’s duct system to maximize airflow.

Wall insulation

Even small, uninsulated cracks and exposed areas within your walls can lead to significant heat loss, drafts, and inconsistent temperatures. We inject high-performance insulation directly into wall cavities, helping to lower energy bills and reduce heating and cooling costs.

top plate sealing

Top plate sealing helps prevent thermal bypass—a common issue where heat escapes around your attic’s insulation.

crawl space encapsulation

Crawl spaces are often responsible for unwanted moisture, radon gas, and temperature swings. Using closed-cell spray foam helps control mold growth, reduce humidity, and improve air quality throughout your home.

We prioritize sustainable, high-performance materials that are carefully selected to meet the specific needs of your home. Whether you’re aiming to reduce energy loss or improve indoor comfort, we tailor our insulation approach to align with your goals. Our retrofit solutions are never one-size-fits-all—every material is chosen with purpose, energy efficiency, and long-term performance and quality in mind.
