Need a fair number before committing? Call (361) 315-4177 and you’ll get one, in writing, before any work starts.
Why Lafayette Homes Are Different
Lafayette sits in the Lamorinda hills, and that topography shapes the insulation work we do here more than almost anything else. Homes climb up Reliez Valley Road, St. Marys Road, and Happy Valley Road – and every rise in elevation changes how wind hits a roofline and how much sun a south-facing attic absorbs. We regularly see 1960s and 1970s ranchers with R-19 batts that have settled to half their rated depth, plus 1980s custom builds where cathedral ceilings leave very little attic cavity to work with.
Summers push into the 90s, and without a properly sealed and insulated attic, the upstairs rooms on the west side of a home can run 10 to 15 degrees warmer than the rest. Winter fog adds the opposite problem: moisture that works into fiberglass batts and reduces their effective R-value. Add in Lafayette’s tree cover and the wildlife that comes with it, and we frequently find contaminated insulation that needs removal before new material goes in.
Our Main Lafayette Services
Most Lafayette homeowners call us for one of three things: attic insulation that’s failing or underperforming, spray foam where air sealing is the real issue, and removal of old or pest-damaged material that shouldn’t stay in place. Each service has its own Lafayette page with full pricing detail.
Attic Insulation in Lafayette
Blown-in fiberglass and Rockwool are the two most common materials we install in Lafayette attics. The job typically involves clearing or topping up existing material to reach a consistent R-value, air sealing around penetrations like recessed lights and bath fans, and adding baffles so soffit vents keep breathing. In Lafayette’s 1960s-era ranchers, we often find attic access hatches that are completely uninsulated, leaking conditioned air year-round. Learn more on our dedicated Attic Insulation in Lafayette page.
Spray Foam Insulation in Lafayette
Spray foam makes sense in Lafayette homes where roof decks, rim joists, and crawl spaces need air sealing as much as insulation. The material expands to fill irregular cavities that fiberglass can’t, and it performs especially well in the cathedral-ceiling additions common in Lafayette’s hill neighborhoods. We stock open-cell and closed-cell options and let the job dictate which one fits, not the other way around. Full details are on our Spray Foam Insulation in Lafayette page.
Insulation Removal in Lafayette
Pest droppings, mold, old vermiculite, or material that’s simply disintegrated after forty years – removal is the step most Lafayette homeowners don’t plan for until we flag it. We vacuum out the old material, treat for odor and contaminants where needed, and leave a clean deck ready for new insulation. Rodent activity from Lafayette’s oak and walnut trees makes this a common job here. See pricing and process on our Insulation Removal in Lafayette page.

What pushes a Lafayette price upward? Access. Attics with low clearance, steep roof pitches, or narrow stairwells add labor time, and crawl spaces cut into a hillside often slow things down too. Whatever the number, you’ll see it in writing before we start – no door-step surprises, no re-quote after the first bag is opened. Call (361) 315-4177 for an exact quote on your home.
