Our Insulation Services
Expert Insulation Contractor Services in Simi Valley CA
Reduce heat gain in summer and heat loss in winter with our high-quality attic insulation services. We assess your attic, seal air leaks, and install the appropriate insulation type—blown-in fiberglass, cellulose, or spray foam—to maximize energy savings and comfort.
Attic Insulation
Attics are one of the biggest sources of energy loss in a home. Our attic insulation services help regulate temperatures and prevent conditioned air from escaping. We assess existing insulation, remove old material if needed, and replace it with high-performance options designed to maintain comfort in every season.
Wall Insulation
Improve both thermal and sound insulation with our seamless wall insulation solutions. We install fiberglass batts, blown-in cellulose, or injection spray foam to fill gaps and cavities, delivering efficient insulation and added noise control.
Crawl Space Insulation
Keep your crawl space dry and energy-efficient with our crawl space services. We install insulation on foundation walls, air-seal, and apply vapor barriers to prevent moisture, mold, and heat loss.
Spray Foam Insulation
For superior air-sealing and insulation, we offer closed-cell and open-cell spray foam. This method creates an airtight barrier that reduces energy loss, dampens sound, and improves indoor air quality.
Garage & Rim Joist Insulation
Residential garages and rim joists are common sources of energy loss. We seal and insulate these areas to eliminate drafts, reduce humidity, and prevent pest infiltration.
Commercial Insulation
Commercial properties require custom insulation solutions that meet code requirements and deliver ROI. We handle full-scale commercial projects—from office building walls to warehouse attic systems—with precision and care.
At Silver Line Insulation, our mission is to create healthier, more energy-efficient living and working environments. We are dedicated to improving indoor comfort, reducing heating and cooling costs, and minimizing the environmental footprint of buildings in Simi Valley and beyond.
