Attic Insulation in Clovis - Same-Day Service, Done Right the First Time

Fast, Reliable Attic Insulation Across Clovis

Attic insulation in Clovis typically costs between $1,800 and $4,600 for a full removal-and-replacement on a 1,800 – 2,800 sq ft home, with top-ups and air-sealing running less. We get calls from Harlan Ranch, Loma Vista, and the streets around Old Town every week, usually because a concrete tile roof is holding attic heat past 10 p.m. and the AC won’t stop running. You’ll have a written price before any work starts, and a live person answers when you call (909) 768-6501. No voicemail trees, no next-business-day callbacks.

Why Thistledown Attic Insulation Is Clovis’s Preferred Attic Insulation Company

Thistledown Attic Insulation is an independently owned Cedarwell-family company, founded in 2003 and led by Neil Barron. Our crews work across Clovis daily, so we know what a Harlan Ranch concrete tile roof does to attic temperatures in August, and we know what tule fog mornings do to a 1990s track home in the central tracts. Background-checked, uniformed technicians show up on time, lay drop cloths from the front door to the attic hatch, and wear shoe covers on every visit.

We hold every job to the Cedarwell Care Promise: clean up like it’s our own home, ask before we move or touch anything, respect the family’s time and quiet hours, and explain the price before the work. The 365-Day Done Right Promise backs every install – if it isn’t done right, we make it right, no debate, no fine print. Families in Clovis call us because they want to know exactly who’s walking through the door and exactly what the attic will look like when we leave.

Scheduling coordinates from our Fresno, Central Valley office, with crews dispatched directly to Clovis neighborhoods. We carry Johns Manville, Knauf, and CertainTeed products on the truck, so most Clovis jobs don’t wait on a supply run.

Attic Mold Removal in Clovis

Attic mold removal in Clovis usually means addressing the specific moisture cycle created by our Valley climate: hot summer afternoons bake attic air past 150°F, then winter tule fog and below-freezing nights pull moisture into the roof deck. When a 1990s or 2000s tract home has compressed or missing insulation, the underside of the roof sheathing cycles between hot and cold daily, and condensation feeds mold in the dark. We start with a full attic inspection to find the moisture source – often a bathroom fan venting into the attic, a disconnected duct, or simply a deck that never dries because the insulation settled and trapped humidity. Mold removal in a Clovis attic typically runs $800 – $2,400 depending on the affected square footage and whether the sheathing needs treatment. After removal, we correct the ventilation and insulation so the mold doesn’t come back.

Mold Assessment and Source Correction

Before we touch any mold, we find why it’s there. In Clovis’s stucco tract homes, the most common culprits are bathroom exhaust fans that terminate in the attic rather than through the roof, and recessed can lights that leak conditioned air into the insulation. We fix the source, then treat the affected framing and sheathing. Removing mold without fixing the airflow means you’ll see it again next winter.

Attic Drying and Ventilation Repair

Clovis attics need to breathe across both seasons – hot dry summers and fog-wet winters. We install or repair attic baffles to keep airflow moving from the soffits to the ridge, and we check that existing vents aren’t blocked by blown-in insulation. A properly vented attic in Clovis should stay within a few degrees of outdoor air even on a 105°F day, and that’s the standard we leave behind.

Attic Insulation Removal in Clovis

Attic insulation removal in Clovis is a job we do regularly for homes built between roughly 1985 and 2010, when code-minimum R-19 or R-30 fiberglass batts were the standard and many builders simply laid them between joists without air-sealing first. Twenty to thirty years of Valley heat, rodent activity, and occasional roof leaks leaves that insulation compressed, dust-laden, and far below its original R-value. In Loma Vista, a 2004 two-story with a concrete tile roof was running its AC 11 hours a day at a 78°F setpoint despite two HVAC techs having cleared the equipment; our crew found the original R-19 batts compressed to roughly R-11, with 152°F attic air at 4 p.m. and still 128°F at 10 p.m. We removed the collapsed batts, air-sealed the top plates and can lights, and blew Owens Corning fiberglass to R-38 with a radiant barrier, cutting measured attic-to-room heat flux enough that the homeowner reported 6 – 7 hours of daily runtime the next August. Full removal in Clovis generally runs $1,200 – $2,800 depending on attic size and access, and it’s the right call whenever old insulation is compressed, contaminated, or no longer performing.

Full Vacuum Removal for Contaminated Attics

When insulation has been soaked by a roof leak, infested by rodents, or simply broken down into dust, blowing new material over it locks the problem in place. We use HEPA-filtered vacuum equipment to pull everything out down to the drywall, so we can see exactly what’s happening at the top plates and can lights. You’ll see a photo of the clean attic before we start installing new material.

Air-Sealing Before New Insulation Goes In

Removal creates the only chance to properly air-seal an attic in Clovis, and it matters more here than most places. Our dual-extreme climate means the same gaps that leak hot air into the house in August leak warm air out during tule fog nights in January. We seal top plates, wire penetrations, can light housings, and duct boots before a single batt or bag of blown-in fiberglass goes down. Skipping this step is why so many Clovis homeowners replace insulation but barely notice a change on the next utility bill.

Trusted Brands We Service in Clovis

We install and service insulation from Johns Manville, Knauf, and CertainTeed, choosing the right product for each Clovis attic rather than forcing one brand into every home. For pet-safe options where a choice exists, we’ll match the product to your household – because the dog will be home during the job, and so will the kids. Our trucks run from the Fresno office into Clovis daily, so we keep common materials stocked for same-week installs across the city. Whether it’s CertainTeed blown-in fiberglass for a Loma Vista two-story or Knauf batts for a tight central Clovis attic access, the product gets matched to the attic plane, the roof type, and the family living below it.

Common Attic Insulation Problems We See in Clovis Homes

• Concrete tile roofs re-radiating heat past midnight. Harlan Ranch and Loma Vista are full of tile roofs that hold heat for hours after sunset, so attic temperatures never drop overnight in summer. Compressed 1990s R-19 batts can’t recover, and the AC never stops.
• Track-home attic planes with settled, compressed batts. Most Clovis tract homes were built between 1990 and 2010 with code-minimum insulation. Twenty to thirty years of settling leaves the outer thirds of the attic effectively uninsulated, creating sharp temperature gradients and condensation points under the roof deck.
• Dual-extreme climate stress on the whole envelope. Our summers hit 110°F ambient and our winter tule fog brings below-freezing nights. An attic insulated only for summer heat still leaks warmth in January, so ducts and top plates that were air-sealed for cooling fail again as winter infiltration paths.
• Bathroom fans and can lights leaking into the attic. In Clovis’s stucco tract homes, the most common air leaks we find are bathroom exhaust fans venting straight into the attic and recessed lights with no seal. They dump moist air into the insulation all winter, and that’s where mold starts.
