Most attic cleanouts and rodent exclusion jobs in Mountain View run between $2,800 and $6,500 depending on contamination level, access difficulty, and whether insulation replacement is needed.

How CertainTeed Products Fail - and How We Fix Them
- CertainTeed InsulSafe SP blown-in fiberglass compacts unevenly in Mountain View’s variable attic temperatures. The loose-fill product settles into valleys between joists, creating thermal bypasses where rodents travel and nest. We remove the compacted material entirely, sanitize the deck, and reinstall to consistent depth with proper baffling at eaves.
- CertainTeed SpeedyR roll batts degrade fastest near roof penetrations where rodents enter. The kraft-faced batts tear at plumbing vent stacks and electrical service masts, the exact gaps mice use. We strip damaged sections, seal penetrations with fire-rated foam and steel mesh, then replace with unfaced batts or blown-in to eliminate the paper food source.
- CertainTeed Optima open-blow system in bonus-room kneewalls collapses when disturbed by rodent activity. The non-combustible loose fill lacks the density to spring back after compression. We find this often in Rex Manor and Old Mountain View split-levels where roof rats have tunneled through. Our fix: remove, air-seal the kneewall sheathing, then reinstall with stabilized cellulose that resists nesting.
- CertainTeed MemBrain smart vapor retarder becomes a contamination trap when rodents deposit waste above it. The variable-permeance film is installed tight to the attic floor in some Mountain View builds from the 2015-2019 window, and rodent urine pools on its surface rather than passing through. We remove the compromised membrane, HEPA-vacuum the subfloor, and reinstall only after full exclusion is verified.
- CertainTeed TrueComfort blown-in cellulose, while generally rodent-resistant, wicks moisture where roof leaks follow gnawed entry points. The borate treatment deters insects but not determined roof rats. We map water staining during cleanout, replace damaged sections, and coordinate with roofers on active leaks before reinsulating.
Our CertainTeed Attic Cleaning & Rodent Proofing Process
- 1
Attic inspection with photo documentation. We identify your CertainTeed product line, measure existing depth, map rodent pathways, and note contamination zones. You receive the photo record before we leave.
- 2
Written price and scope. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No work starts without it.
- 3
Contaminant removal and HEPA filtration. We extract soiled CertainTeed insulation using sealed containment, negative air pressure, and HEPA filtration. All waste is bagged and removed from site.
- 4
Sanitization and structural repair. The attic deck, joists, and ductwork receive enzymatic treatment. We sister chewed wires, replace gnawed flex duct, and seal all penetrations at the attic floor with fire-rated materials.
- 5
Rodent exclusion with steel and concrete. Entry points are sealed with 1/4-inch hardware cloth, copper mesh, and concrete where roof lines meet stucco. We warranty the exclusion for one year.
- 6
Reinsulation and blower-door verification. New insulation is installed to specified depth. On applicable jobs, we run before-and-after blower-door tests to document air-sealing improvement.
What CertainTeed Attic Cleaning & Rodent Proofing Costs in Mountain View

|---|---|
| Light cleanout, no insulation replacement, basic exclusion | $2,800 - $3,900 |
| Moderate contamination, partial CertainTeed removal, full exclusion | $4,200 - $5,800 |

Price moves with attic square footage, pitch (steeper = more labor), number of entry points found, and whether HVAC ducts require replacement. We also service Reflectix radiant barrier systems where rodent damage has compromised the reflective surface. Call (669) 259-0406 for your written price - estimates are free.

FAQs
No, professional cleaning and rodent proofing by an independent service provider does not void CertainTeed’s product warranty, which covers manufacturing defects only, not damage from pests or environmental conditions. We document our work with photos to support any future warranty claims you may need to file. Call (669) 259-0406 if you’d like us to review your installation paperwork.
You can switch brands without issue - CertainTeed warranties cover the original installation period, not subsequent modifications by independent contractors. We often recommend blown-in cellulose or stabilized fiberglass from Johns Manville or Knauf for replacement after rodent damage, depending on your attic’s moisture profile and framing configuration. We’ll explain the trade-offs in your written scope.
If you see scattered droppings limited to one corner and the insulation structure is intact, cleaning with spot replacement usually suffices. If contamination covers more than 30% of the attic floor, insulation is compressed into tunnels, or odor penetrates the living space, full restoration is the honest recommendation. We tell you which category you’re in during the initial inspection, with photos.
Most Mountain View appointments are scheduled within 3-5 business days, with emergency exclusions available sooner if active rodent entry is confirmed. Same-week starts are common in spring when roof rat activity peaks in the Rex Manor and Monta Loma areas. Call (669) 259-0406 to check current availability.
Spot repair is cheaper only when damage is localized to less than 15% of coverage and the remaining insulation meets current depth standards. In Mountain View’s climate, partially disturbed blown-in fiberglass rarely blends well with new material, creating thermal irregularities. We price both approaches in your written estimate so you can see the five-year cost difference.
