Attic Insulation Upgrades for Redmond Homes

Attics play a major role in how well a home retains heat in winter and stays cool in summer. We frequently find attics with settled insulation, exposed framing, or air leaks around lighting and ductwork.

We specialize in:

• Removal of old or contaminated insulation
• Installation of new blown in or batt insulation
• Options for fiberglass, cellulose, or spray foam
• Sealing of common attic air leakage points

These upgrades can improve comfort throughout your home and reduce strain on heating and cooling systems.

Crawl Space Insulation, Moisture Protection, and Mold Solutions

Moisture is a common issue in crawl spaces across the Eastside, especially in homes with poor drainage or aging vapor barriers. When left untreated, moisture can lead to insulation failure, mold growth, odors, and air quality concerns that affect both the structure and the living areas above.

Common solutions include:

• Removal of damaged insulation and debris
• Installation of new crawl space insulation
• Vapor barrier installation or replacement
• Mold remediation and basic sanitizing
• Sealing of vents and gaps where appropriate
• Ventilation improvements when needed
• Recommendations for drainage or sump pump systems

A properly insulated and protected crawl space helps keep floors warmer, indoor air cleaner, and prevents recurring moisture problems.

Spray Foam Insulation Applications

Spray foam insulation is well suited for areas where air leakage is a concern or where traditional insulation does not perform as well. It expands to seal gaps and provides consistent coverage in difficult spaces

Common applications include:

• Rooflines and vaulted ceilings
• Rim joists and band joists
• Garage ceilings beneath living areas
• Home additions and remodels

We help determine whether spray foam or another insulation option is the best fit for your specific property.

Rodent Damage Cleanup and Prevention

Homes near greenbelts, parks, and wooded areas can be more vulnerable to rodent activity. Rodents often damage insulation and vapor barriers while contaminating crawl spaces and attics.

We offer:

• Removal of contaminated insulation and materials
• Cleaning and basic sanitizing of affected areas
• Identification and sealing of entry points
• Installation of new insulation after cleanup

Addressing both the damage and the access points helps prevent recurring problems and protects your investment.

Air Sealing and Energy Efficiency Improvements

Even well insulated homes can lose energy through small air leaks around ductwork, plumbing penetrations, and framing transitions. Professional air sealing helps reduce drafts and temperature swings, improves the effectiveness of insulation, lowers heating and cooling costs, and increases overall comfort throughout your home.

Air sealing is often combined with insulation upgrades for maximum results and long term energy savings.
