Types of Insulation We Retrofit

Our highly experienced team of expert insulation professionals is capable of retrofitting a wide variety of insulation materials, including:

Fiberglass Insulation

Cost-effective, resistant to moisture and non-combustible, fiberglass insulation provides excellent thermal and soundproofing properties perfect for attics, walls and crawl spaces where easy installation and affordability are key. Fiberglass insulation is excellent at minimizing heat transfer, lowering energy bills and improving indoor comfort by maintaining consistent temperatures.

Spray Foam Insulation

With its superior air-sealing properties, high R-value and resistance to mold and pests, spray foam insulation expands to fill gaps and cracks, creating a tight seal in walls, basements and hard-to-reach areas where maximum energy efficiency is needed. Spray foam insulation eliminates drafts, significantly reducing energy waste and enhancing overall comfort by keeping conditioned air inside.

Cellulose Insulation

Created from recycled materials and treated for fire resistance, cellulose insulation is an eco-friendly option that’s excellent at filling irregular spaces in attics and walls — especially in older homes with settling insulation. Cellulose insulation provides effective thermal insulation and soundproofing, reducing energy usage and creating a more peaceful, comfortable indoor environment.

Signs You Need to Replace Your Insulation

With its harsh winters and humid summers, Chicago places extra demand on insulation to ensure consistent indoor comfort and prevent energy waste. Properly functioning insulation is essential to keep your home warm during freezing winters and cool during sweltering summers, ensuring year-round comfort and efficiency.

Knowing when it’s time to replace the insulation in your home is vital to protecting its energy efficiency and thermal protection. Below are a few of the strongest indications that it’s time to consider retrofitting the insulation in your home:

  • Uneven indoor temperature: Cold or hot spots throughout your home may indicate inconsistent thermal protection.
  • High energy bills: Rising heating and cooling costs often result from ineffective insulation that’s no longer reducing energy loss.
  • Drafts and gaps: Feeling drafts near windows, doors, or walls can signal gaps in insulation or insufficient coverage.
  • Visible property damage: Signs like mold, mildew or water stains may indicate insulation has been compromised by moisture.
  • Cold interior surfaces: If walls, floors or ceilings are unusually cold to the touch during winter, insulation may need updating.
  • Increased pest infestations: Rodents or insects nesting in insulation can reduce its effectiveness and require immediate attention.
  • Home is older: Properties built before modern energy codes often have outdated or degraded insulation.
