Health Risks

Indoor Air Quality

Unsealed cracks and holes in your home’s building envelope, along with deteriorated insulation, can allow outdoor pollutants such as allergens, dust, and bacteria to enter your living space. This increases the risk of developing respiratory irritation, allergic reactions, and other illnesses, especially for individuals with conditions like asthma.

Moisture and Mold

Damaged insulation due to water leaks, gaps, and poor air sealing significantly raises the risk of mold growth in your home. Hidden water damage may be present, especially after severe weather events. Improper installation, such as DIY attempts, can lead to trapped moisture beneath newly installed insulation, fostering the growth of mold, rot, and wood damage.

Deteriorated insulation material exposed to leaks and condensation contributes to increased humidity within your house. Excessive moisture creates an environment for bacteria, viruses, and mold growth, posing health risks. Additionally, damp or deteriorated wood can attract pests like carpenter ants, termites, and other foundation-damaging insects.

Higher Costs

Material Removal

Old insulation may contain dangerous materials like asbestos, commonly used until the 1980s. Asbestos particles are toxic and pose health risks such as mesothelioma. Disturbed old fiberglass insulation can also release irritating particles. If unsure about the insulation type, contacting professionals for evaluation is essential to mitigate health risks, potentially increasing the cost of removal and replacement.

Climate Control

Proper insulation and air sealing regulate temperature, reducing the rate of heat transfer and improving climate control. Damaged or improperly installed insulation is less effective against unwanted heat loss or gain, leading to increased reliance on HVAC systems. This results in higher energy costs, especially during extreme weather conditions.

HVAC Maintenance

Inadequate insulation and air sealing cause HVAC systems to overwork, constantly running to maintain desired temperatures. The system’s frequent operation leads to higher maintenance fees, repairs, and potentially premature replacement. 

The Importance of Removing Old Insulation and Replacing It with Spray Foam

Replacing old insulation with spray foam insulation offers numerous benefits. Spray foam, installed by a professional spray foam insulation contractor, creates an airtight seal, improving indoor air quality, preventing moisture and mold growth, reducing humidity, and ensuring energy efficiency.
