Whether you're upgrading your attic, building a custom home, or enhancing your commercial space, SDI Insulation delivers tailored, high-performance solutions.

Residential Insulation for Walnut Creek Homes

Insulation is one of the most cost-effective ways to make your home more energy-efficient. At SDI Insulation, our in-house team of specialists will assess your property and recommend a combination of insulation materials and methods to reduce energy loss, control sound, and maintain consistent indoor temperatures.

Our Walnut Creek residential services include:

Spray Foam Insulation

Ideal for hard-to-reach areas and tight building envelopes, spray foam delivers exceptional R-value while sealing air leaks. Our insulation installers near me use advanced application techniques to ensure proper coverage, helping you improve home comfort and lower your heating and cooling costs.

Blown-In Insulation

For attics and older homes, blown-in insulation is a fast and effective solution. As trusted attic insulation contractors, we use either fiberglass or cellulose to fill gaps and create a dense thermal barrier, improving energy performance without major structural changes.

Batt Insulation

Batt insulation is one of the most popular solutions for walls, ceilings, and floors in residential construction and remodeling. Our house insulation contractors in Walnut Creek ensure accurate cuts and precise fitting to eliminate cold spots and gaps that often reduce insulation effectiveness.

Insulation Removal and Replacement

If your home has outdated or damaged insulation, it may be time for a replacement. We offer full-service insulation removal and can upgrade your space with energy-efficient products that comply with California's Title 24 building code requirements.

Soundproof Insulation

Whether you're dealing with road noise, loud neighbors, or want more privacy between rooms, our soundproofing insulation solutions will help you create a quieter, more peaceful home.
