Fast, Reliable Blown In Insulation Across Clovis
Blown in insulation in Clovis typically runs $2,100 – $5,400 for an average single-family attic, depending on square footage and the R-value you’re targeting. Most jobs finish in a single day. If your upstairs rooms run hot or your cooling bills climb every July, the problem is usually a thin, settled attic blanket, not your AC unit. Alden Insulation Fresno serves Clovis homeowners with written pricing, background-checked crews, and a 365-day guarantee on every job. Call (559) 666-2260 for a free estimate.
We know Clovis attics. We’ve worked in Harlan Ranch, Loma Vista, the Old Town grid, and the acreage properties east of McCall. The homes here have a specific failure pattern we’ll get into below, and it’s one most insulation companies never mention.
Why Alden Insulation Fresno Is Clovis’s Preferred Blown In Insulation Company
Alden Insulation Fresno operates under The Garrison Standard, part of the Garrison Partners family since 2002. That means every Clovis job gets a written price before any equipment comes off the truck, and a written 365-Day Done Right Promise when the work is complete. If the insulation fails within that year, we return at no charge. No fine print, no phone tag.
Our crews arrive inside the scheduled window. Not a four-hour range. The technician at your door is background-checked, uniformed, and knows Clovis housing stock well enough to spot trouble before the blower hose goes up. You’ll know exactly who’s walking into your home, and the number you approve is the number on the invoice.
When a Clovis homeowner calls about a hot bonus room or a garage that’s baking, we don’t send a salesman with a binder. We send someone who can diagnose the R-value, explain thermal bypass in plain language, and tell you whether Blown In Insulation will actually solve the problem or whether you need air sealing first. That discipline is why homeowners across Clovis keep our number.
Blown In Insulation Contractors in Clovis
Blown In Insulation Contractors in Clovis handle two jobs most homeowners overlook: topping up settled attic coverage and dense-packing closed cavities like garage ceilings and bonus room floors. The work involves feeding loose fiberglass or cellulose through a calibrated blower hose to hit a specified R-value, usually R-38 to R-49 for Clovis attics under tile roofs. Pricing for attic top-up work in Clovis runs $1,800 – $3,600; dense-packing a garage ceiling above a finished bonus room runs $2,400 – $4,800 depending on access and square footage.
Attic Top-Up Over Settled Batts
Most 1990s and early 2000s Clovis tract homes were built with R-19 to R-30 fiberglass batts. After 20 years of Central Valley heat, those batts have compressed and pulled away from top plates. We blow loose-fill directly over the existing layer after air sealing the gaps at the wall line. It’s the most cost-effective upgrade you can make to a Clovis home.
Garage Ceiling and Bonus Room Dense-Pack
If your bonus room sits above the garage and runs 10 – 15°F hotter than the rest of the house, the garage ceiling is almost certainly uninsulated or thinly insulated. We dense-pack the cavity to R-38, which stops the heat transfer from the garage slab and door. This is the single highest-impact fix we perform in Clovis subdivisions.
Cellulose Insulation in Clovis
Cellulose Insulation in Clovis is a strong option for homeowners who want a denser, air-resistant attic blanket. Cellulose is made from recycled paper treated with borate for fire and pest resistance, and it performs better than fiberglass at blocking airflow through small gaps and around framing. We install GreenFiber cellulose blown to R-38 or R-49, with most Clovis attics costing $2,300 – $5,200 depending on depth and whether we remove old material first.
Cellulose for the Diurnal Swing
Clovis summers bring 100°F afternoons and 60°F nights. That daily swing pushes air through every seam in your attic floor. Cellulose’s higher density slows that air movement more effectively than fiberglass batts, which is why we recommend it for older Clovis homes where top plates and recessed light housings are already leaking.
Over Existing Batts or Clean Start
If your existing attic insulation is dry and uncontaminated, we can blow cellulose directly over it. If rodents, roof leaks, or decades of dust have compromised the old material, we remove it first and start clean. Either way, the written price includes the full scope before any work starts.
Trusted Brands We Service in Clovis
We install and remove insulation using products from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. For most Clovis attic jobs we recommend Owens Corning AttiCat fiberglass or GreenFiber cellulose, depending on your home’s construction and existing insulation. You can look up any of these brands before we arrive. We don’t push proprietary products or mystery material. You’ll know exactly what’s going into your attic and why.
Common Blown In Insulation Problems We See in Clovis Homes
- Exposed top plates in 1990s-era attics. The original batts have pulled back from the wall line, leaving a continuous gap that lets conditioned air escape into the attic. We air seal and blow over these gaps on nearly every Clovis tract home we touch.
- Missing insulation above garages and bonus rooms. In Harlan Ranch and Loma Vista especially, builders often skipped garage ceiling insulation entirely. Upstairs bedrooms above those garages run 10 – 15°F hotter, and the fix is a direct dense-pack.
- Uninsulated detached workshops on acreage properties. Homes east of Fowler Avenue and out toward the Clovis foothills often have detached shops with oversized roll-up doors. The roof assembly is usually uninsulated, which turns the shop into an oven by noon and drags down whole-property comfort.
- Thermal bypass at recessed lights and ceiling penetrations. Older Clovis homes weren’t air sealed at the time of construction. Recessed can lights act as small chimneys, pulling attic heat down into the living space. Sealing and covering these is standard on every job we quote.
Pricing for Blown In Insulation in Clovis, CA
Attic top-up work in Clovis runs $1,800 – $3,600 for most homes up to 2,000 square feet. Full attic insulation from a clean deck runs $2,400 – $5,400. Garage ceiling dense-pack above a finished bonus room runs $2,400 – $4,800. Cellulose runs slightly higher than fiberglass because the material is denser and requires more pounds per square foot to hit the same R-value. What moves the price is attic access, depth of existing insulation, and whether removal is required first. The price we quote in writing is the price you pay. Call (559) 666-2260 for a specific number.

FAQs About Blown In Insulation in Clovis
The garage ceiling below that bonus room is almost certainly uninsulated or under-insulated, so heat from the garage slab and the sun-baked garage door radiates straight up through the floor cavity. We fix this by dense-packing the garage ceiling to R-38, which typically drops the bonus room temperature by 8 – 12°F within a day. Call (559) 666-2260 and ask for a garage ceiling inspection.
Yes. We air seal the top plates and any ceiling penetrations first, then blow new fiberglass or cellulose directly over the existing batts to reach R-38 or R-49. This is the most cost-effective insulation upgrade for 1990s Clovis homes. The existing batts do not need to be removed unless they’re wet, moldy, or rodent-contaminated.
Yes, but only if the roof assembly above the shop is insulated and air sealed. An uninsulated roof deck radiates heat downward all day, and the roll-up door adds another layer of heat gain. We insulate the shop’s roof or ceiling to R-38 and air seal the eaves. The door itself may still need weatherstripping, but the attic work removes the largest heat source. Call (559) 666-2260 for a quote.
The daily 30 – 40°F swing between Clovis afternoons and nights causes air in the attic to expand and contract constantly, which pulls dust and moisture through gaps in the insulation blanket. Over 15 or 20 years this degrades loose-fill coverage and creates thermal bypass at top plates and recessed lights. The fix is air sealing first, then adding fresh blown-in material to hit current R-value targets.
Yes. Most Clovis tract homes have concrete tile roofs, and the tiles are brittle. Our crews access the attic from inside the home or through existing attic hatches rather than walking the roof surface. We don’t lift or break tiles to run the blower hose. This protects your roof warranty and keeps the job clean.
