These seals stop heat from escaping in winter and keep cool air inside during summer, helping maintain consistent indoor temperatures. By reducing the workload on your HVAC system, weather stripping and foam gaskets can lower energy bills and improve comfort year-round.
They also help keep dust, pollen, and noise out, creating a quieter, cleaner, and more comfortable living environment while boosting your home’s energy performance.
Beyond Air Sealing Services & Home Efficiency, our company offers additional services for homes and businesses
Spray foam insulation plays a major role in creating an airtight, energy-efficient home. It expands quickly to fill cracks and gaps around wiring, plumbing, and framing areas where traditional insulation often misses. By forming a tight seal, spray foam blocks air leaks that cause drafts and heat loss.
This airtight barrier improves overall insulation performance, helping your HVAC system work more efficiently. It keeps warm air inside during winter and cool air in during summer, maintaining steady indoor temperatures year-round.
Air sealing contributes to a healthier indoor environment by reducing the influx of pollutants, allergens, and humid air. Combined with proper ventilation, air sealing ensures that natural airflow helps prevent indoor air quality issues and moisture buildup.Our air sealing services are available throughout Northwest
Air sealing is one of the most cost-effective ways to save energy and improve your home’s energy efficiency in any existing home. Homeowners can significantly reduce heat loss and improve heating and cooling performance by identifying and addressing air leaks throughout the building envelope. At Anderson Heating, Air & Insulation, we prioritize targeted air sealing measures that increase comfort and deliver long-term energy savings.
The average home can leak air through dozens of small openings, which can significantly affect indoor air quality and comfort. These include gaps in exterior doors, window frames, electrical outlets, and even switch plates. Uncontrolled air leakage allows cold air and outside air to enter while heated or cooled air escapes, forcing HVAC systems to work harder and increasing energy costs. Our team helps you seal these leaks effectively to maintain consistent indoor temperatures.
Key problem areas in the building envelope include places such as rim joists, attic entrance hatches, crawl spaces, basements, and the attic foundation. These areas often have dirty spots that indicate air movement. By sealing cracks, open seams, and other gaps, Anderson Heating, Air & Insulation improves air tightness and reduces air leakage significantly.
Spray foam is one of the most versatile air-sealing techniques we use. It expands to fill gaps around electrical wiring, plumbing penetrations, and framing. Ideal for filling cracks and large voids, spray foam reduces air leaks and adds insulation value, making your home more power efficient and helping to save energy throughout the year.
A blower door test is a diagnostic tool we use to detect where homes leak air. This test helps us identify the exact locations of air infiltration and develop an effective air sealing strategy. Whether you’re working on new construction or improving a current home, this test ensures that all significant air leaks are addressed.
Air tightness is crucial to maximizing the performance of insulation and HVAC systems. Without proper sealing, insulation cannot function efficiently, leading to heat loss and inconsistent temperatures. At Anderson Heating, Air & Insulation, we focus on improving the air tightness of your home to ensure better indoor comfort and lower energy bills.
Uncontrolled airflow through cracks and gaps allows humid air to enter wall cavities and attics, which can lead to moisture problems and mold and mildew growth. Air sealing stops this movement, protecting your home from costly moisture issues. In turn, this helps maintain a healthier indoor environment.
Sealing the basement is crucial for improving energy efficiency, as it is often a major source of air leaks. Crawl spaces, basements, and rim joists are often overlooked in air sealing tasks. These areas can leak air, increasing drafts and cold spots. We dramatically reduce heat loss and improve energy efficiency by sealing cracks in these regions with spray foam or metal and foil tape.
The attic floor and access hatches are notorious for leaking air. Warm air naturally rises, and if these areas are not properly sealed, energy loss is inevitable. We install bubble gaskets, weather stripping, and insulation around attic access hatches to stop air leakage and improve comfort.
Exterior doors and window frames are common areas where air leaks occur. Installing high-quality weather stripping and bubble gaskets is a simple yet effective way to seal air leaks and prevent cold air from entering your home. These air sealing measures help maintain comfortable indoor conditions year-round.
Tiny gaps around electrical outlets, switch plates, and wiring allow significant air leakage over time. We install bubble gaskets behind outlet covers and use caulk or spray foam to seal wiring penetrations. These small adjustments make a huge impact on the overall energy efficiency of your home.
When you seal air leaks, you reduce the workload on your hvac system, allowing your heating and cooling systems operate more efficiently. Less energy is needed to maintain a comfortable temperature, reducing wear and tear on your HVAC units. This can lead to longer equipment life, fewer repairs, and noticeable energy savings.
Fireplace flues and chimneys often have loose seams that leak air and allow moisture to enter. Using fire-resistant materials such as sheet metal, furnace cement, or specialized caulks, we seal these problem areas safely and effectively, keeping your home warm and fuel-efficient.
Spray foam isn’t always the answer in areas exposed to high temperatures or irregular shapes. We use sheet metal and foil tape to cover large or awkward gaps, especially around mechanical penetrations and ductwork. These materials offer long-lasting, secure seals that withstand temperature changes and moisture.
Seal gaps around outlets and wiring using caulk, foam, or outlet gaskets to stop drafts, improve efficiency, and maintain indoor comfort.
Air leaks around doors, windows, and outlets let outside air in and conditioned air out, making HVAC systems work harder and raising energy costs.
Air sealing blocks humid air from entering walls and crawl spaces, reducing condensation, mold, and mildew while keeping your home clean and healthy.
Air sealing reduces drafts and leaks, helping HVAC systems run efficiently, use less energy, last longer, and lower monthly utility bills.
Warm air rises and escapes through unsealed attic areas. Adding gaskets, insulation, and weatherstripping prevents heat loss and boosts efficiency.
Common air leaks occur in rim joists, attics, crawl spaces, and basements. Sealing these gaps improves comfort, efficiency, and temperature control year-round.
