CertainTeed Attic Cleaning & Rodent Proofing in Glendale: What to Know First
CertainTeed attic cleaning and rodent proofing in Glendale typically runs between $1,200 and $4,800 depending on attic size, contamination level, and how much exclusion work the roofline needs. Most jobs are completed in one to two days, and we quote a firm price before any work starts. We’re an independent CertainTeed service provider, not a manufacturer affiliate, which means we tell you the honest truth about what your attic needs, even when that answer is less work than you expected. This page is for Glendale homeowners with CertainTeed insulation products (usually InsulSafe SP or OPTIMA blow-in fiberglass) who’ve discovered rodents, droppings, or odor in the attic space. Call (747) 246-7237 and a live person answers, day or night.
How CertainTeed Products Fail – and How We Fix Them
- InsulSafe SP fiberglass gets tunneled and matted by rodents. Blown-in fiberglass is loose enough for rats and mice to burrow through, and Glendale’s roof rat population is relentless once they find a gap in an eave or vent. The insulation compresses as they nest, which craters its R-value in those spots even after the rodents are gone. We vacuum out the contaminated material, sanitize the decking, and blow fresh insulation to restore the full thermal barrier.
- OPTIMA blow-in fiberglass absorbs urine odor fast. CertainTeed’s OPTIMA system is a good product, but no blown fiberglass resists soaking in rat or squirrel urine. The smell penetrates the fibers and the accumulation of droppings creates a health hazard well beyond what air sealing can cover. We remove every inch of affected insulation, treat the decking with an enzyme-based decontamination spray, and then re-insulate.
- Staple-up batt lines like CertainTeed’s Sustainable Insulation get shredded for nesting material. In older Glendale homes with batt-facing CertainTeed products in the attic, rodents tear the kraft facing off to line their nests. Once the facing is gone, the batts sag and lose fit, which is why spot cleaning never really works. We strip the damaged batts, clean the joist bays, and reinstall properly sized new material.
- Rodents chew through CertainTeed vapor retarder and access points around ductwork. The gaps where plumbing stacks, bathroom fans, and HVAC lines pass through the attic floor are the most common entry points we find in Glendale. Rats don’t need much: a quarter-sized hole is plenty. We seal these with hardware cloth, copper mesh, and high-grade expanding foam, because the exclusion work matters just as much as the cleanup.
- CertainTeed SmartBatt with its foil-facing shows clear signs of animal activity. The reflective facing makes urine trails and gnawing marks easy to spot, which actually helps us map where the rodents are entering and traveling. We inspect the full attic floor and the under-side of the roofline before quoting, because finding the entry point is the only way the job sticks.
Our CertainTeed Attic Cleaning & Rodent Proofing Process
- 1
We answer the phone and schedule a walk-through. You’ll talk to a real person at (747) 246-7237 and we’ll come out to Glendale at a time that works, with no trip charge inside the service county.
- 2
We inspect the attic top to bottom. We map the CertainTeed product you have, identify entry points, check for electrical wire damage and HVAC duct leaks, and document what we find.
- 3
We give you a fixed, line-by-line price. No vague allowances, no surprise add-ons after we start. You’ll know exactly what the cleanup, sanitizing, exclusion, and re-insulation costs before we roll a single hose.
- 4
We remove and decontaminate. Commercial vacuums pull out the old CertainTeed insulation and droppings. Then we treat the decking and joist bays with an enzyme cleaner that neutralizes odor and bacteria.
- 5
We rodent-proof the attic. Every gap we found gets sealed with steel mesh, copper wool, and foam in the right combination for each opening. No exclusion work means the problem returns, so we don’t skip it.
- 6
We blow fresh insulation and leave the space better than we found it. You get new CertainTeed (or another brand if that suits the job better) blown in to the right R-value for Glendale’s climate. Every job carries the Done Right Promise: if it’s not done right, we make it right.
What CertainTeed Attic Cleaning & Rodent Proofing Costs in Glendale
Here’s the honest spread for the jobs we do most in Glendale. Every price includes the cleanup, the sanitizing, and the exclusion work, unless noted:
- Basic attic cleanout and spot exclusion (small single-story home, light contamination): $1,200 – $1,800
- Full attic cleanout with sanitizing and re-insulation (1,000-1,500 sq ft attic): $2,200 – $3,800
- Heavy contamination with full exclusion and new CertainTeed blow-in (1,500+ sq ft, multiple entry points): $3,800 – $4,800
- Rodent-proofing only (no cleanup or re-insulation needed): $850 – $1,600 based on roofline access and gap count
What moves the price: attic size, how deep the contamination goes, whether the old insulation is salvageable (it rarely is once rodents nest in it), and how many entry points need sealing. Every estimate is free, and we’ll give you a second opinion on any written quote at no charge. Call (747) 246-7237 for a firm number on your attic.
Why Glendale Homeowners Call Walt’s Insulation for CertainTeed Work
We’ve been doing this since 2000, and we’re not a franchise with a rotating cast of subcontractors. Walt Brenner runs the business, and the truck you’ll see in Glendale is ours. When we work on a CertainTeed attic, we know what we’re looking at, because we’ve cleaned and re-insulated hundreds of them across the San Fernando and San Gabriel valleys. If your CertainTeed product is still in good shape but the access points around a Reflectix radiant barrier install are compromised, we’ll tell you that too. The point is this: you get an honest assessment from a locally owned crew with a published address and license number, not a call center reading off a script. And a live person answers whenever you call, day or night. Do it right the first time or you’ll be doing it twice, and the second time costs more.
FAQs
Generally no, because we’re removing contaminated insulation that already failed due to animal activity, and restoring the attic to a proper condition. As an independent CertainTeed service provider, we’re not authorized to speak for the manufacturer, but in our experience, a clean attic with proper exclusion work extends the life of any insulation product. Call (747) 246-7237 and we’ll walk you through your specific situation.
In most cases, yes. We keep the schedule flexible for rodent issues because the damage compounds every day the animals stay. A live person answers at (747) 246-7237 and we’ll give you an honest arrival window.
Almost always, yes. Rodent urine and droppings soak into blown fiberglass, and trying to salvage it means living with the odor and the bacteria. We’ll show you what we find during the inspection and let you decide with real information.
Our exclusion work is covered under the Done Right Promise. If rodents get back in through a gap we sealed, we come back and make it right. We don’t hand you a warranty card and disappear, and we’ve been in business long enough that you can hold us to that.
Cleaning removes the insulation and droppings. Sanitizing treats the decking, joists, and any affected surfaces with an enzyme cleaner that breaks down the bacteria and neutralizes odor at the source. We do both on every rodent job, because cleaning alone leaves the attic smelling like a rat latrine on hot Glendale days.
