CertainTeed Attic Cleaning & Rodent Proofing in Tustin: What to Know First
We provide independent CertainTeed attic cleaning and rodent proofing in Tustin, with most jobs completed in one to two days and a written price delivered before any work starts. As an independent CertainTeed service provider, we are not affiliated with or authorized by CertainTeed Corporation. Our typical turnaround for a standard attic cleanout, sanitizing, and rodent exclusion runs 1-2 business days; larger restorations with insulation replacement may stretch to 3-4 days. We do not quote over the phone without seeing the space, but we do publish what these jobs actually cost in Tustin below. This page is for homeowners in Tustin Legacy, Old Town Tustin, and the surrounding zip codes who have CertainTeed insulation or building envelope products in their attic and need cleanup, decontamination, or rodent sealing that respects the original material specs.

How CertainTeed Products Fail - and How We Fix Them
- CertainTeed Optima blown-in fiberglass settles unevenly in Tustin’s dry, hot attic cycles. The material sheds density where rodents have tunneled, creating bare spots at the eaves that read cold on a thermal camera. We remove the compromised batts, sanitize the substrate, and reinstall to the original R-value spec - usually R-38 for Tustin’s Climate Zone 8 - after sealing every penetration.
- CertainTeed InsulSafe SP loses loft when contaminated by rodent urine. The sodium borate fire retardant reacts with organic waste, forming hard clumps that no longer trap air. We bag and remove the SP, HEPA-vacuum the decking, apply an enzymatic decontaminant, and replace with fresh material or an alternative if the homeowner prefers.
- CertainTeed SpeedyR rigid foam board gaps at the perimeter after rodent gnawing. Mice follow the thermal bridge at the foam-to-wood junction; once through, they nest behind the board. We pull the damaged sections, rodent-proof the gap with 26-gauge galvanized flashing, then refoam or switch to a different R-value strategy depending on the roof pitch.
- CertainTeed MemBrain vapor retarder tears where rodents traverse the attic floor. The smart retarder is designed to vary permeance with humidity, but a 3-inch rip defeats the purpose and traps moisture against the drywall in Tustin’s spring marine layer. We replace the MemBrain in affected bays only, documenting the repair with photos for the homeowner’s file.
- CertainTeed TrueComfort batts compress at the top plates where squirrels have nested. The Kraft facing delaminates from the fiberglass, dropping the effective R-value by 30-40% in that bay. We remove the nest, sanitize, air-seal the top plate with acoustical sealant, and reinstall fresh batts to full thickness.
Our CertainTeed Attic Cleaning & Rodent Proofing Process
- 1
Inspection and blower-door baseline. We pressurize the house to 50 pascals and record the CFM50 reading. In Tustin Legacy homes built 2015-2020, we typically see 3,500-5,000 CFM50 before any work; the number tells us how much conditioned air is escaping through attic bypasses.
- 2
Written scope and price. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
- 3
Rodent exclusion and air sealing. We seal top plates, can lights, plumbing penetrations, and chimney chases with fire-rated foam, steel wool, and galvanized flashing. Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can.
- 4
Contaminated material removal and sanitizing. CertainTeed products are bagged by type - we separate Optima, InsulSafe, batts - for proper disposal. The decking gets HEPA-vacuumed and treated with enzyme decontaminant.
- 5
Reinstallation and blower-door verification. New insulation goes in to code. We run the blower door again and publish the before-and-after numbers so you can verify the air-sealing result.
- 6
Documented Photo Record delivery. You receive thermal images, the written R-value report, and the CFM50 comparison before the crew leaves.
Before
AfterWhat CertainTeed Attic Cleaning & Rodent Proofing Costs in Tustin
Most attic cleanout and rodent-proofing jobs in a Tustin home this size run between $2,800 and $5,400. Here’s what moves that number:
- Attic cleanout and HEPA vacuum only: $1,200-$2,100
- Cleanout + sanitizing/decontamination: $2,800-$4,200
- Full cleanout, sanitizing, rodent exclusion, and insulation replacement to R-38: $4,500-$7,800
- SpeedyR or rigid foam repair/replacement: add $800-$1,600
- MemBrain vapor retarder replacement (partial): add $400-$900
Factors that push the price: multiple rodent entry points requiring roofline work, compressed or urine-damaged insulation requiring full removal rather than spot treatment, and homes with finished attic floors that limit access. We also service Reflectix radiant barrier systems if your attic has a hybrid install. Call (657) 286-7673 for an exact quote - estimates are free, and we offer a Free Second Opinion on any written estimate you’ve already received.
Why Tustin Homeowners Call Topside Attic Insulation Tustin for CertainTeed Work
We’ve logged a lot of time in Tustin Legacy, where the post-redevelopment housing stock made blower-door testing a baseline step rather than an afterthought. Wes Okafor and our crew have handled CertainTeed products since the Optima line first showed up in local builds, and we know the difference between a batt that can be salvaged and one that needs to come out. Our 365-Day Done Right Promise applies to all completed work, and our materials come from multiple suppliers - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and others - so we’re not locked into pushing one product. Calls are answered by a live person, 24/7. Background-checked, uniformed technicians. A written price before any work starts, always.
FAQs
CertainTeed’s product warranty covers manufacturing defects regardless of who installs or services the material, but workmanship warranties from the original contractor are separate and may not transfer. As an independent CertainTeed service provider, we provide our own 365-Day Done Right Promise on labor. Call (657) 286-7673 to review what coverage applies to your specific install.
We source CertainTeed products through standard distribution channels; for some repairs, we use quality aftermarket materials that meet or exceed the original spec, and we note the substitution in your written scope. If OEM is required for a specific warranty claim you’re pursuing, tell us upfront and we’ll source accordingly.
Spot repair is cheaper only if the contamination is limited to less than 20% of the attic floor and the remaining insulation still meets its labeled R-value. In our experience, rodent urine saturates deeper than it appears, and compressed Optima or InsulSafe SP rarely recovers full loft. We test with a depth gauge and thermal camera, then show you the numbers. Call (657) 286-7673 for an assessment.
We typically schedule estimates within 24-48 hours for Tustin addresses, with work starting 1-3 days after you approve the written scope. Emergency rodent exclusion - where active entry is causing ongoing damage - can sometimes be addressed same-day. Call (657) 286-7673 to check current availability.
Yes. Many Tustin attics have layered insulation from multiple eras or contractors. We identify each material during inspection, separate for disposal by type, and specify replacement products in the written scope. We also service Reflectix radiant barrier if that’s part of your assembly.
