Owens Corning Attic Cleaning & Rodent Proofing in Menlo Park: What to Know First
As an independent Owens Corning service provider, we handle attic cleaning and rodent proofing for Owens Corning insulation systems in Menlo Park, typically completing jobs in one to two days with a written price locked before any work starts. Most Menlo Park homeowners with Owens Corning AttiCat blown-in fiberglass or ProCat loose-fill systems call us after finding rodent droppings, compressed insulation, or evidence of nesting in attics that haven’t been accessed in years. We don’t quote over vague descriptions - we inspect, photograph, and deliver a flat written price on site. Call (510) 876-4113 to schedule. Same-week appointments are usually available.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Fiberglass Blown-In settles around duct penetrations. The loose-fill consistency that makes AttiCat easy to install also means it shifts when rodents burrow, creating bare thermal bridges around HVAC boots and electrical penetrations. We remove the contaminated material, seal the penetrations with fire-rated caulk and metal flashing, then reinstall fresh Owens Corning ProCat or an equivalent R-38 blown fill.
- ProCat Loose-Fill compresses under rodent runways. Owens Corning’s higher-density professional product still packs down to R-19 or lower in paths where roof rats travel repeatedly between nesting and food sources, common in Menlo Park’s older ranch homes near the Allied Arts Guild area. We extract the compacted strips, sanitize the decking beneath, install exclusion barriers, and restore full R-38 depth with new material.
- Owens Corning Foamular Rigid Board edges become rodent chew zones. The pink XPS board used for attic hatches and knee-wall applications has a crisp edge profile that rats and mice target for gnawing access. We cut replacement hatches from 1/2-inch plywood with continuous metal flashing edges - a detail that eliminates the chewable foam exposure entirely.
- Ecotouch PINK Fiberglass Batt frays and loses R-value when urine-saturated. The formaldehyde-free binder breaks down under sustained rodent contamination, causing the batts to separate and fall from joist bays. We bag and remove the degraded material, apply enzyme-based decontamination to the substrate, and reinstall either fresh batts or switch to blown-in depending on the attic geometry.
- VentSure ridge vent intakes clog with nesting debris. Owens Corning’s continuous ridge vent system, common on Menlo Park homes built 2005-2018, draws attic air through a narrow slot that roof rats pack with insulation fragments and droppings. We clear the channels, screen the terminations with 1/4-inch galvanized hardware cloth, and verify airflow with a smoke pencil before closing up.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
- 1
Inspection with photo documentation. We enter through the attic hatch, photograph all contamination zones, and identify every penetration, duct boot, and vent termination that needs attention.
- 2
Blower-door baseline test. Wes Okafor starts each job with a blower-door test - a pressurization measurement that quantifies exactly how much conditioned air the house is leaking before a single bag opens. This gives us a CFM50 number that guides the air-sealing scope.
- 3
Written price and scope. We deliver a flat price, written warranty, and photo-based scope before any work begins. No exceptions.
- 4
Extraction and decontamination. Contaminated Owens Corning material is bagged and removed. We apply enzyme treatment to decking and joists, then seal all air leaks with fire-rated caulk, metal flashing, and expanding foam where appropriate.
- 5
Exclusion installation. Rodent proofing includes 1/4-inch hardware cloth over vents, metal kick plates at eave intersections, and sealed penetration points. We verify with another blower-door test and hand you the pre- and post-installation report showing actual ACH50 numbers.
- 6
Reinsulation and final documentation. Fresh Owens Corning or equivalent insulation is installed to spec depth. You receive a Documented Photo Record and the 365-Day Done Right Promise in writing.
Before
AfterWhat Owens Corning Attic Cleaning & Rodent Proofing Costs in Menlo Park
Most attic cleaning and rodent proofing jobs on Owens Corning systems in Menlo Park run between $2,800 and $6,500, with reinsulation adding $1.50 to $3.20 per square foot depending on product and depth. Here’s what moves the number:
| Scenario | Typical Range |
|---|---|
| Partial cleanout, spot rodent proofing, no reinsulation | $2,800 - $4,200 |
| Full cleanout, decontamination, comprehensive exclusion, reinsulation to R-38 | $4,800 - $6,500 |
| Knob-and-tube wiring present (requires electrician coordination) | Add $800 - $1,500 |
| Attic hatch replacement with metal-edged detail | $350 - $600 |
Homes near Menlo Park’s older neighborhoods - the 94025 zip around downtown and the Allied Arts Guild area - often need more extensive air sealing due to original construction gaps. We don’t guess; we inspect and write the price on site. Call (510) 876-4113 for a free estimate.

FAQs
No - Owens Corning’s product warranty covers manufacturing defects, not installation or maintenance work performed by independent contractors. We use Owens Corning-specified installation depths and densities, and we document our work so any future warranty claim on the material itself remains clean. If you have concerns about a specific product registration, call us at (510) 876-4113 and we’ll review it with you.
For blown-in fiberglass, we typically reinstall Owens Corning ProCat or AttiCat to maintain consistent thermal performance and avoid density mismatches that can create convection currents. For batt replacement in knee walls or odd angles, Johns Manville or Knauf equivalents perform identically if matched for R-value and faced/unfaced configuration. We explain the choice in your written scope before ordering.
If contamination is localized to 30% or less of the attic footprint and the remaining Owens Corning material tests at 90% or better of original R-value, restoration with spot reinsulation is usually the better value. Above that threshold, or when urine saturation has reached the drywall ceiling below, full removal and replacement is more cost-effective long-term. We assess this during inspection and put both options in writing.
Most jobs take one to two working days once started. We can usually inspect within 48 hours and schedule work within a week. Emergency situations - active rodent entry with visible ceiling staining - get prioritized. Call (510) 876-4113 and a live person will find the next available slot.
Exclusion work eliminates attic entry when every penetration larger than 1/4 inch is sealed, which is our standard. We also identify exterior grade issues - overhanging branches, unsecured crawl space vents - that contribute to recurrence. The 365-Day Done Right Promise covers our exclusion work; if rodents re-enter through a point we sealed, we return at no charge.
Seal the leaks first. The insulation has nowhere useful to go until you do. Call (510) 876-4113 today to schedule your free estimate. We’ll inspect your Owens Corning attic system, deliver a written price before any work starts, and show you the blower-door numbers that prove the result.
