- Every job includes the Kingswell Guarantee: written price, arrival window, clean job site, written guarantee, free return visit if it fails within 365 days.

Why Woolsey Insulation Sacramento Is Loomis’s Preferred Attic Insulation Company
Glenn Hartley, who leads our Sacramento-based team, built Woolsey around a specific idea: write the price down before the crew shows up, then stand behind the work in writing. Loomis homeowners respond to that because a lot of them have been through the opposite, a contractor who quoted one number on the phone and another at the door. We schedule by appointment and hold it. If we say a crew arrives between 8 and 10 a.m., that’s when the truck pulls up, even on the long drives out toward Loomis Basin.
Our technicians are background-checked and uniformed, so you know exactly who’s walking onto your property. We work with eight insulation brands, including Owens Corning, Johns Manville, Knauf, and Rockwool, which means the material we recommend fits your attic and your heat load, not whatever’s left on the truck. For Loomis specifically, we plan for detached structures and non-standard openings that other crews rush past. The Attic Insulation work we do here is the same Kingswell standard we apply everywhere: written price, done in one trip, guaranteed for 365 days.
Blown In Insulation in Loomis
Blown In Insulation in Loomis typically costs $1,500 – $3,800 for a standard attic, with larger custom homes and detached workshops running toward the top of that range. Blown-in insulation, usually fiberglass or cellulose, is loose material blown through a hose into the attic cavity. It fills odd-shaped spaces around scissor trusses and vaulted ceiling framing far better than batts, which is why it’s the most common choice for the large custom homes and older ranch houses throughout Loomis.
Top-Up Work
Many Loomis homes have some insulation already, often R-19 or less in attics that should carry R-38 or R-49 for our summer heat. A top-up costs $900 – $2,200 and brings existing insulation up to current code without tearing anything out.
How We Avoid Rushed Jobs
We add travel and access time into every Loomis estimate. That means verifying the attic hatch seal actually gets checked, the far reaches of the attic over the garage get dense-packed, and the oversized door header gets sealed before we leave.
Insulation Contractors in Loomis
Insulation Contractors in Loomis range from general handymen to licensed specialists, and the gap in quality comes down to whether anyone actually checks the result. Woolsey’s crews are insulation-only: attic insulation and spray foam, nothing else. Our Loomis jobs follow The Kingswell Way: we say the price, show up in the window, leave the attic and driveway cleaner than we found them, put the guarantee in writing, and come back free if it fails within 365 days.
What a Proper Job Includes
Air sealing before insulation, baffles at the eaves to protect soffit vents, and verification of final depth across the entire attic, not just the spot nearest the hatch. On Loomis acreage properties, that also means checking the shared wall between any attached garage or workshop and the living space.
Independent, Not a Chain
We’re an independently owned and operated Kingswell company. That matters because the name on the invoice is the same name that answers if you call back in six months. No corporate call center, no franchise territory. Glenn Hartley’s team handles Loomis directly.
Trusted Brands We Service in Loomis
We install and service insulation from Johns Manville, Knauf, Rockwool, and CertainTeed, among others. The brand matters less than the R-value and the air sealing, but working with these manufacturers means we can match the right product to a Loomis attic’s specific problems: high summer heat gain, scissor truss cavities, detached workshops, or old ranch homes with uneven framing. If you know what’s in your attic and want the same material for a top-up, we can get it. If you don’t, we’ll tell you straight what works best for this climate. Dispatch and scheduling for Loomis are coordinated from our Sacramento office, and crews carry the materials needed for most jobs on the first visit.
Common Attic Insulation Problems We See in Loomis Homes
- Uninsulated attached workshops or oversized garages: Heat soaks through the shared wall or ceiling into living space. Air sealing the header and dense-packing the wall cavity stops most of it.
- Vaulted ceilings and scissor trusses: Uneven attic cavities get under-insulated when installers use the wrong technique. Blown-in fiberglass or cellulose fills the varied depths correctly.
- Long drives and gated entries: Rushed crews skip verifying attic hatches and eave baffles because they’re watching the clock. We schedule one trip but give it enough time to be done properly.
- Radiant barrier gaps: Many Loomis homeowners installed radiant barrier in the 2000s, but gaps at roof penetrations and hatch openings undermine it. Sealing those first is what makes the barrier actually work.
Pricing for Attic Insulation in Loomis, CA
A standard blown-in attic insulation job in Loomis on a 1,500 – 2,000 sq ft home typically runs $1,800 – $3,400.

FAQs About Attic Insulation in Loomis
We treat the shared wall as part of the attic insulation job, not an afterthought. That means air sealing the top plate, dense-packing the wall cavity if it’s open, and insulating the workshop ceiling properly so heat stops bleeding into your living space. Call (279) 972-8973 and describe the layout; we’ll tell you what’s needed and what it costs before we ever send a crew.
Yes, blown-in insulation handles scissor trusses and vaulted ceiling framing better than batts because the loose material fills irregular depths instead of leaving gaps. The key is the installer accounting for varied cavity depths, which is standard practice on our Loomis jobs. We verify final R-value across the whole attic, not just the easy spots.
Yes, we seal and insulate oversized garage door headers as part of the attic job. On Loomis properties with detached workshops or big attached garages, this is one of the highest-impact fixes we do, often cutting afternoon temperature swings in the adjoining room by 15°F or more. It’s included when we quote the job, not an add-on surprise.
Most Loomis custom homes take four to seven hours for a standard blown-in job including air sealing and baffle work. Detached workshops or homes with multiple attic zones can push to a full day. We plan for the entire job in one trip, so you’re not waiting on a second visit because someone forgot to check the hatch seal.
Radiant barrier helps most in Loomis’s 100°F-plus summers when your attic has a large roof surface and high heat gain, especially on custom homes with big roof planes. If your insulation is already R-38 or better, a radiant barrier can still cut cooling load by reflecting heat before it reaches the insulation. We’ll tell you straight whether it’s worth the cost for your specific roof before you spend anything. Call (279) 972-8973 for an honest answer and a written quote.
Out near a horse property off King Road, we insulated a 2,400 sq ft attic over a detached workshop that had been radiating heat into the adjacent living space. Our crew dense-packed Owens Corning blown-in insulation to R-38 and sealed the oversized rolling door header with foam, cutting the afternoon temperature swing in the attached home office by 18°F on a 104°F day. The owner wanted it done in one trip before a farrier arrived, so we finished by 2 p.m. and confirmed the workshop stayed comfortable without running a portable AC. That’s the kind of planning every Loomis job gets, because acreage properties don’t have time for a second trip.
Unlike nearby Roseville or Rocklin, many Loomis properties have detached workshops and oversized garage doors with long service drives. That changes how an insulation crew has to work. We plan equipment access, we budget time for gated entries, and we verify the sealing around large non-standard openings instead of treating them like standard garage doors. A crew that rushes those openings leaves gaps that undo half the benefit of the insulation. We don’t rush. We show up once, with the right plan and the right materials, and the job gets finished correctly before we pull out of the driveway.
