Icynene Attic Cleaning & Rodent Proofing in Yorba Linda: What to Know First
We provide independent Icynene attic cleaning and rodent proofing in Yorba Linda, with most jobs completed in one to two days and a written price delivered before any work starts. As an independent Icynene service provider, we carry no manufacturer affiliation, which means we source parts based on what actually fixes your attic, not what moves a dealer’s inventory. Most Yorba Linda homeowners with Icynene open-cell or closed-cell foam systems call us after finding rodent droppings, compressed insulation, or the telltale ammonia smell that open-cell Icynene LD-C-50 seems to hold onto longer than denser foams. If your attic needs cleaning, sanitizing, and sealing against re-entry, call (909) 323-1675 for a free estimate with a written scope.
How Icynene Products Fail - and How We Fix Them
- Icynene LD-C-50 open-cell foam absorbs rodent urine and holds odor. The 0.5 lb/ft³ density that makes LD-C-50 excellent for air sealing also makes it a sponge for biological contamination. In Yorba Linda’s 140°F July attic peaks, that odor reactivates seasonally. We remove contaminated sections, HEPA-vacuum the substrate, and apply an enzymatic decontamination before deciding whether to re-foam or switch to a closed-cell replacement in affected bays.
- Icynene MD-C-200 closed-cell develops surface friability where rodents tunnel. The 2.0 lb/ft³ density resists compression but rodents will excavate nesting cavities at the foam-to-framing interface, creating voids that compromise both thermal and air barriers. We cut back to sound foam, treat the cavity, and reinstall with attention to the monolithic seal that MD-C-200 is specified for.
- Icynene Classic Max - the 0.5 lb open-cell staple - compresses under foot traffic during HVAC service. Yorba Linda’s tight lots often put air handlers in attic spaces that techs traverse quarterly. Compressed Classic Max loses R-value permanently; we remove and replace with new material, or recommend upgrading to MD-C-200 in high-traffic zones where the homeowner plans long-term occupancy.
- Icynene ProSeal Eco - the newer closed-cell line - shows poor adhesion to dusty OSB in older Yorba Linda tract homes. The Savi Ranch and eastside developments built 1985-1999 often have attic decks that have never been cleaned. We mechanically abrade and prime before any foam touch-up, because ProSeal Eco’s HFO blowing agent chemistry is less forgiving of substrate contamination than earlier MD formulations.
- All Icynene lines create a vapor barrier that traps moisture if the roof deck leaks. Homeowners discover this when a rodent-chewed vent boot or cracked tile lets water in, and the foam hides the damage until stains appear below. We inspect the roof deck systematically during attic cleaning, document with photos, and mark suspect areas for your roofer before we seal anything back up.
Our Icynene Attic Cleaning & Rodent Proofing Process
- 1
Call and schedule. A live person answers at (909) 323-1675, 24/7. We book a site visit, not a sales pitch.
- 2
Attic inspection with photo documentation. We identify your Icynene product line by density and color, map contamination zones, and find every rodent entry point. You get a Documented Photo Record before we leave that day.
- 3
Written price and scope. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No work starts without your signature on both.
- 4
Contamination removal and substrate treatment. HEPA vacuuming, enzymatic decontamination for biological waste, and mechanical prep for any foam repair. We bag and remove all contaminated material; Yorba Linda’s waste stream handles the disposal, not your driveway.
- 5
Rodent exclusion and foam restoration. We seal entry points with steel mesh and appropriate sealants, then repair or replace Icynene foam using OEM-spec material or quality aftermarket equivalent based on your system’s age and your preference. Seal the leaks first. Then insulate. The numbers will tell you whether it worked.
- 6
Final inspection and documentation. Second photo set, written completion record, and activation of the 365-Day Done Right Promise. If we touched air sealing, you get before-and-after blower-door numbers.
What Icynene Attic Cleaning & Rodent Proofing Costs in Yorba Linda
Most Icynene attic cleaning and rodent proofing jobs in Yorba Linda run between $2,400 and $5,800. The lower end covers a contained Classic Max open-cell cleanup with light rodent exclusion; the upper end involves extensive MD-C-200 closed-cell removal, full deck decontamination, and comprehensive sealing of a hillside home with complex roof geometry off Bastanchury Road.
What moves the price:
- Foam type and density - closed-cell removal takes longer and costs more per board foot to replace
- Contamination depth - surface soiling versus saturated substrate requiring removal to framing
- Accessibility - truss bays with limited headroom, steep pitches common in Yorba Linda’s eastern hills
- Extent of rodent damage to HVAC, wiring, or roof deck (we document and flag; repair by your electrician or roofer)

Why Yorba Linda Homeowners Call Topside Attic Insulation Yorba Linda for Icynene Work
We’ve cleaned and restored Icynene foams in Yorba Linda since 2016, from the flat-roofed condos near Imperial Highway to the steep attic spaces in the foothills where summer heat turns rodent waste into a persistent problem. Wes Okafor built this operation on blower-door depressurization testing - measuring how much conditioned air your house leaks per hour - because a clean attic with unsealed top plates is just a clean attic that still wastes energy. Our background-checked, uniformed technicians know the difference between LD-C-50 and MD-C-200 by sight and density, and we carry Reflectix and other multi-brand materials when Icynene replacement isn’t the right call. Every job closes with a Documented Photo Record and the 365-Day Done Right Promise: if it’s not done right, we make it right.
FAQs
No - proper cleaning and repair by a qualified contractor does not void Icynene’s material warranty, though damage caused by rodents or moisture is not covered by that warranty in the first place. We document our work so you have a record if warranty questions arise later. Call (909) 323-1675 if you’d like us to review your original installation paperwork.
We source both OEM Icynene material and quality aftermarket equivalents from our supplier network including Demilec and other approved vendors. For warranty-traceable jobs or color-matched repairs, we use OEM; for older systems where exact matching isn’t critical, we may recommend a compatible aftermarket that performs to the same density and R-value spec. We explain the trade-off and price both options in your written scope.
Repair is almost always cheaper when contamination is localized and the foam substrate is sound - typically 40-60% less than full removal and reinstallation. We recommend full removal only when the foam is saturated, extensively tunneled by rodents, or failing adhesion across broad areas. Your written estimate will show both paths if either is viable.
We schedule most inspections within 48 hours, and emergency calls for active rodent infestation or roof leak exposure get same-day or next-day priority. A live person answers (909) 323-1675 around the clock; you’ll speak to someone who can book the appointment, not a callback queue.
We warranty our exclusion work for 365 days under the Done Right Promise, and we document every sealed entry point with photos mapped to your attic diagram. If rodents re-enter through a point we sealed, we return and fix it at no charge. The best proof is the follow-up inspection we offer at 90 days - included, not extra.
