Free estimate." url: "https://ecosremodeling.com/services/insulation/" --- # Insulation Installation ## What does insulation installation include? EcoStar Remodeling & Construction handles insulation installation for homes in the Bay Area, Los Angeles and our other California offices, in attics, walls, floors and crawl spaces, as a licensed general contractor (CSLB 1034806). A project covers an inspection of what is there now, removal of old or damaged insulation when needed, sealing of air gaps, and new fiberglass, blown-in or spray foam insulation, with the ventilation the attic needs. It starts with a free estimate, where we check the attic, the walls we can reach and the rooms that stay too hot or cold. [Request a free insulation estimate](https://ecosremodeling.com/free-quote/).

A licensed insulation contractor understands how to evaluate your home’s specific needs. The common materials are fiberglass batts, blown-in insulation and spray foam. Each option has its benefits, and choosing the right one depends on your home’s structure, budget, and efficiency goals. Installation matters as much as the material: gaps, compressed batts or uneven coverage cut its performance, and insulation work may fall under California’s Energy Code (Title 24, Part 6). Our work is backed by a 2-year workmanship warranty. ## How does insulation improve energy efficiency and comfort? - Insulation slows the flow of heat through the attic, walls and floors. In summer it keeps heat out so the air conditioning runs less; in cooler months it holds warmth in. This balance leads to lower energy consumption and more stable indoor temperatures throughout the year.In Los Angeles, where temperatures can fluctuate between hot summers and cooler evenings, proper insulation helps regulate indoor temperatures and reduce energy costs year-round. It also evens out hot and cold rooms, softens outside noise and, together with air sealing, keeps dust and drafts out.

Rooms that stay much hotter or colder than the rest of the house are another. If your home was built decades ago and hasn’t been updated, it’s likely that an insulation upgrade could significantly improve performance.Insulation that got wet from a roof leak or humidity loses its effect and can feed mold, so it should be replaced. A remodel, a new roof or an attic conversion is also a practical time to add insulation while the space is open. **How an insulation project runs:** a free estimate and attic inspection, a plan for the material and the areas to cover, a permit when your city requires one, removal, air sealing and installation, then a final walkthrough with you. ## Why choose EcoStar for insulation?

How Much Does Insulation Installation Cost? We can’t give you a specific number without seeing your home. The price depends on the area to cover, the material, whether old insulation has to be removed first, and how easy the attic and walls are to reach. We price each line in a free estimate. Which Insulation Works Best in an Attic? Blown-in insulation and fiberglass batts are common attic choices, and spray foam also seals air gaps. We recommend one after looking at your attic’s framing, ventilation and access. Can You Insulate Existing Walls? Often, yes. Closed walls can be filled with blown-in insulation through small holes that we patch afterward, and walls opened during a remodel can take batts or spray foam. Where Do You Install Insulation?
