Attic Cleaning Services in Clovis
Attic Cleaning Services in Clovis address what years of Central Valley dust, rodent activity, and old insulation have left behind. Before we blow in fresh insulation, the attic needs to be clear of debris, droppings, and anything else that compromises air quality or hides damage. In Clovis’s 1990s tract homes, we commonly find compressed fiberglass batts buried under dust and the occasional rodent nest near attic access points.
Most attic cleaning jobs in Clovis run $600 – $1,400, depending on attic size and how much material needs to come out. That includes Insulation Removal in Clovis, vacuuming, and basic sanitizing. If the attic has extensive rodent damage, the scope expands and we’ll tell you that in writing before starting.
When Cleaning Isn’t Optional
You need attic cleaning before adding new insulation if you can see visible mold, smell a musty odor in upstairs rooms, or know rodents have been in the attic. Putting fresh insulation over contaminated material doesn’t fix the problem. It traps it.
Air quality matters too. Compromised attic air can seep into living space through recessed lights and unsealed top plates, which is a common issue in Clovis homes built before air sealing became standard practice.
Cleaning Before Top-Up or Replacement
If you’re adding a blown-in top-up, the existing insulation should be inspected first. Clovis attics with compacted fiberglass often have hidden moisture issues that only show once material is pulled back. Cleaning gives us a clean surface to work with, and it’s the responsible order of operations.

Attic Mold Removal in Clovis
Attic Mold Removal in Clovis is common in homes where bathroom fans vent into the attic instead of through the roof, and in attics with poor baffle ventilation. The Valley’s foggy winters create condensation on the underside of roof sheathing, and that moisture feeds mold growth on rafters and decking. We see it frequently in Clovis homes built in the 1990s and early 2000s, especially where ridge venting was never added.
Attic mold remediation in Clovis typically runs $900 – $2,100, depending on the square footage affected and whether the source of moisture also needs correcting. The job includes removing contaminated insulation, treating affected framing, and addressing the ventilation or exhaust issue that caused the problem in the first place. Skip that last step and the mold comes back.
Ventilation Issues That Cause Mold
Baffles blocked by blown-in insulation are the single most common cause we find. When soffit vents are covered, air can’t move through the attic, and condensation settles in. Clovis homes with tile roofs complicate this because ridge vents often weren’t included in original construction.
Bathroom fans venting into the attic rather than outside are also a recurring issue in Clovis tract builds. Warm, moist air hits the cool underside of the roof deck and condenses. That’s a direct path to mold.
Mold Removal Before Insulation Upgrades
If mold is present, it must be treated before new insulation goes in. We install and remove insulation using products from CertainTeed, Knauf, and Rockwool, but no brand of insulation solves a mold problem. The source of moisture has to be corrected first, and we’ll include that in the written scope.
Common Attic Insulation Problems We See in Clovis Homes
- Compacted blown-in fiberglass: Over 15 – 20 years, blown-in fiberglass settles to roughly half its rated R-value. A Clovis attic rated R-38 at installation is often functioning at R-19 or less, which can’t hold up against 100°F+ summer days.
- Missing insulation above garages and bonus rooms: In Harlan Ranch and Loma Vista subdivisions, home inspectors routinely note missing or thin insulation above garages and bonus rooms. The result is upstairs bedrooms that run 10 – 15°F hotter than the rest of the house.
- Thermal bypass at top plates and recessed lights: Conditioned air leaks through unsealed gaps at wall top plates and around recessed light fixtures. In Clovis tract homes built to older energy codes, this is a primary driver of high cooling bills.
- Blocked soffit vents from prior insulation work: Attic baffles weren’t always installed correctly in 1990s Clovis builds. When blown-in insulation covers the soffit vents, attic temperatures climb and moisture builds up in winter.

FAQs About Attic Insulation in Clovis
Because the insulation above that room is either missing, compacted, or bypassed by air leaks. In Clovis homes with bonus rooms above garages, the garage ceiling and kneewalls often lack insulation entirely. We find this in Harlan Ranch and Loma Vista regularly. The fix is air sealing top plates, adding baffles, and blowing insulation to R-38 across the problem areas. Call (559) 666-2260 and we’ll inspect it.
Air sealing matters as much as insulation in Clovis. The diurnal temperature swing means conditioned air escapes through gaps at top plates and recessed lights, and hot attic air gets pulled into living spaces. Insulation without sealing is like wearing a coat that’s unzipped. Every job we quote includes a sealing assessment.
If your attic insulation looks flat and dense rather than fluffy, it’s compacted. If it’s below the top of your ceiling joists, it’s not hitting its rated R-value. Clovis homes built in the 1990s often started with R-30 to R-38, but 25 years of settling means many are functioning at half that. We measure it during a free estimate.
Yes, when cleaning includes restoring ventilation. Blocked soffit vents force attic temperatures up, and that heat radiates into your living space. Cleaning out compacted insulation and installing baffles restores airflow, which drops attic temps and helps your insulation do its job. Call us for an inspection, and we’ll tell you if cleaning is part of your fix or a separate issue.
Yes. If mold is present, adding insulation over it seals the problem in and can worsen air quality in your home.
