Work with a Professional Insulation Company You Can Trust

Installing insulation is one of the most effective and affordable ways to reduce energy loss and take control of rising energy costs. In many homes—especially those over 20 years old—existing insulation has deteriorated or no longer meets modern efficiency standards. Outdated materials allow valuable heated and cooled air to escape, forcing your HVAC system to work harder than necessary. At Northwest Weatherization, our professional service helps homeowners stop wasting money, improve indoor air, and enjoy a more comfortable living space year-round.

Poor insulation isn’t just inconvenient—it’s expensive. Homes that lack proper insulation often struggle with uneven temperatures, higher utility bills, and reduced HVAC efficiency. Our insulation solutions are designed to seal gaps, stabilize indoor temperatures, and extend the life of your heating and cooling system, all while lowering long-term energy costs.

Complete Home Insulation Solutions for Maximum Efficiency

Wall Insulation

Walls are one of the biggest sources of heat loss in any home. We install high-performance spray-in wall insulation that restricts airflow and fully encapsulates wiring and piping. This material does not settle over time, resists mold growth, and delivers a higher R-value than traditional options. Proper wall insulation can reduce heat loss by up to 66%, significantly improving comfort and energy efficiency.

Floor & Crawl Space Insulation

Uninsulated floors and crawl spaces allow cold air and moisture to move freely into your home. Our team uses the right combination of insulation and vapor barriers based on each area’s unique conditions. From sub-floors and access hatches to exposed piping, we select materials that deliver the greatest performance while improving indoor air quality and overall comfort.

Air Sealing & Duct Sealing

Air sealing is essential for homes with ducted HVAC systems. Leaky ductwork allows unfiltered air—often containing dust, allergens, and contaminants—to enter your home. Unlike some insulation companies, we prioritize sealing ductwork to improve indoor air, protect your HVAC system, and boost overall HVAC efficiency. Stopping air leaks helps your system work smarter, not harder.

Frequently Asked Questions About Home Insulation

How does insulation help lower energy costs?

Proper insulation reduces heat loss in winter and heat gain in summer, allowing your HVAC system to operate more efficiently and lowering monthly energy bills.

Can insulation improve indoor air quality?

Yes. Insulation combined with air sealing helps prevent outdoor pollutants, allergens, and moisture from entering your home, resulting in cleaner indoor air.

Why is air sealing important for HVAC efficiency?

Air leaks force your HVAC system to work harder to maintain temperature. Sealing gaps and ductwork improves airflow, reduces strain on the system, and increases HVAC efficiency.

How do I know if my home needs new insulation?

Common signs include high energy bills, uneven temperatures, drafts, and an older home with original insulation materials.
