Why Laurel Attic Insulation Is Lafayette’s Preferred Attic Insulation Company

Lafayette homeowners keep our schedule full for a simple reason: we show up when we say we will, and we put the price in writing before the blower hose comes off the truck. Chase Whitaker built Laurel Attic Insulation around a straightforward idea: insulation work shouldn’t require a leap of faith. Our technicians arrive in uniform at a live, trackable time, not a four-hour window. You’ll get before-and-after photos of your attic, a written guarantee on the work, and a digital invoice you can pay from your phone.

We’re part of the Relay Home Co. family, founded in 2003, and every job carries the Relay Visibility Guarantee. That means book a visit in a tap, watch your technician’s arrival on a map, and see photo proof of the finished attic before you sign off. When a Lafayette customer calls at 9pm with a question about their estimate, a live person answers. No voicemail queue, no callback roulette.

Lafayette’s hillside lots and canyon-adjacent neighborhoods aren’t like flat, suburban tracts. We’ve worked in attics off Moraga Road, up near the Lafayette Reservoir, and in the older sections of downtown where roof pitches vary block to block. That local repetition means our crews already know what they’re walking into before they pull up.

Blown In Insulation in Lafayette

Blown in insulation in Lafayette is the most practical choice for the majority of homes here, and here’s why: Lafayette’s hillside and canyon lots often have low, shallow attic spaces with limited clearance, which makes blown-in insulation the only workable option for many homes. Fiberglass batts need room to be fluffed and aligned; blown-in cellulose or fiberglass just needs a hose and a nozzle. We routinely use special hose-and-nozzle setups to reach the far eaves on low-pitch roofs where a person simply can’t crawl.

Cellulose for Canyon-Adjacent Homes

We run a lot of GreenFiber cellulose in Lafayette, particularly in the Reliez Valley and Happy Valley areas where squirrels and roof rats are a fact of life. Cellulose is treated with borates, which discourages pests from nesting. When we blow it to an R-49 target, it also deadens the sound of raccoons on the roof at 3am in a way batts never will.

Fiberglass for Budget-Conscious Top-Ups

If your attic already has some insulation but it’s settled, blown-in fiberglass from Owens Corning or Johns Manville is a cost-effective top-up. A typical 1,200-square-foot attic in Lafayette runs $1,000 to $1,800 for a full top-up to R-49. We’ll measure your existing depth, calculate the gap, and give you a written price before we start blowing.

Insulation Contractors in Lafayette

Insulation contractors in Lafayette aren’t all the same, and we say that from experience cleaning up after other crews. The biggest issue we see is compressed batts in low-clearance attics: an installer who can’t get his shoulders into the eaves will shove a batt in sideways, crush it, and leave you with R-11 where you paid for R-30. Our approach starts with an attic inspection, honest measurements of what’s actually up there, and an air-sealing plan before any insulation goes in.

What a Real Inspection Covers

Before we quote anything, we check the top plates, can lights, attic hatch, and knee walls. In Lafayette’s older homes, the attic hatch is often a hollow plywood square with zero weatherstripping, acting like an open chimney for conditioned air. Sealing that alone can drop a monthly bill noticeably. We document everything with photos so you can see exactly what we saw.

Removal Before Re-Insulation

Some Lafayette attics need the old stuff pulled out first. Rodent activity in canyon-adjacent neighborhoods contaminates and flattens insulation, and blowing new material over the top just buries the problem. We’ll tell you honestly if your existing insulation can stay or needs to go. No upsell, just what the attic shows us.

Trusted Brands We Service in Lafayette

We stock and install materials from Owens Corning, Rockwool, Johns Manville, Knauf, CertainTeed, Icynene, Demilec, and GreenFiber. That’s not a brag list; it means we match the material to your house instead of installing whatever is on the truck. For most Lafayette attics we recommend either GreenFiber cellulose or Owens Corning fiberglass, but if you want Rockwool’s fire resistance for a hillside lot near open space, we’ll price it straight up. We keep local inventory in the Bay Area dispatch network so Lafayette jobs don’t wait on a warehouse in Stockton.

Common Attic Insulation Problems We See in Lafayette Homes

• Compressed batts in low-clearance attics. Lafayette’s shallow roof pitches mean installers often can’t reach the far eaves, so batts get shoved and crushed. The result is R-value gaps you can’t see from the attic hatch.
• Rodent contamination near canyon open space. Homes along the Lafayette-Moraga border and near Briones Regional Park deal with squirrels and rats that shred batt insulation and leave droppings throughout the attic. This requires removal, not a top-up.
• Knee-wall bypasses in split-level and hillside homes. Many Lafayette contemporaries and split-levels have knee walls behind bedroom closets that were never insulated or sealed. Stack-effect air leakage pulls conditioned air right through those gaps, and new attic insulation alone won’t fix it.
• Attic hatch leakage on older ranches. The 1950s and 60s ranchers across Burton Valley and downtown Lafayette almost universally have unsealed attic hatches, often just a piece of drywall set over the opening. This single gap can negate 30% of the value of new insulation.
