Owens Corning Spray Foam Insulation Nationwide

Owens Corning Spray Foam Insulation in West Hollywood: What to Know First

We provide independent Owens Corning spray foam insulation in West Hollywood, typically scheduling within 48 hours and completing most jobs in a single day. Most attic spray foam jobs in West Hollywood homes run between $2,800 and $5,400 depending on square footage, foam type, and whether the roof deck needs prep work. We give you a written price before anyone lifts a tool, and we seal every air leak before a single ounce of foam goes in.

How Owens Corning Products Fail - and How We Fix Them

• Owens Corning AttiCat blown-in settling above open-cell spray foam - The AttiCat PINK system is common in West Hollywood attics, but when it’s blown over improperly cured open-cell foam (especially in the humid weeks before Santa Ana season), the cellulose weight compresses the foam’s top layer and drops the effective R-value by 20-30%. We strip back the blown-in, verify the foam’s full cure with a moisture probe, then reinstall the AttiCat at proper depth per manufacturer spec.
• Foam-FR 25 thermal barrier delamination on garage ceilings - Owens Corning’s intumescent coating is required by California code on occupied-space separations, but in West Hollywood’s older garages with unvented soffits, summer heat buildup causes the coating to crack and separate from the foam substrate. We remove the failed barrier, recondition the foam surface, and reapply Foam-FR 25 with proper mil thickness verified by wet-film gauge.
• Closed-cell foam shrinkage at rim joists in hillside homes - West Hollywood’s canyon-adjacent properties (think areas north of Sunset with walk-out basements) often get closed-cell applied too thick in a single lift, exceeding Owens Corning’s pass-thickness limits. The foam pulls away from the sill plate and creates a thermal bypass. We cut back the failed material, install in 1-inch lifts per spec, and verify adhesion with a pull-test.
• ProPink L77 loose-fill contamination in spray foam cavities - When L77 is used as a hybrid system with spray foam in wall cavities, West Hollywood’s older lath-and-plaster walls shed dust that mixes with the loose-fill and settles at the cavity bottom. The top of the wall ends up underinsulated. We extract the contaminated fill with a reverse-flow vacuum, seal the back of the plaster with a vapor-smart primer, then reinstall.
• Cathedral ceiling foam gaps at rafter heels - Owens Corning’s recommended vented-unvented hybrid details are often skipped in West Hollywood’s 1960s-1980s pitched roofs, leaving a 4-6 inch dead zone at the eave where ice damming risk concentrates (yes, even here - we get freeze-thaw cycles in January). We remove the existing insulation, install proper baffles for continuous ventilation, then spray foam to full depth with no compression gaps.

Our Owens Corning Spray Foam Insulation Process

1. 1
   Call and schedule. A live person answers 24/7. We book a site visit, usually within 48 hours in West Hollywood.
2. 2
   Site assessment and blower-door test. We pressurize the house to 50 pascals - a blower-door test that shows, in one number, how much conditioned air your building envelope is losing. Wes Okafor and his crew have found homes off Santa Monica Boulevard leaking 5,000+ CFM50 because top plates were never sealed.
3. 3
   Written price and scope. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1: no work starts without it.
4. 4
   Air sealing first. Top plates, can lights, penetrations, and rim joists get sealed. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order.
5. 5
   Spray foam installation. We apply open-cell or closed-cell per the engineered scope, in proper lifts, with real-time thickness verification. OEM-specified products or quality equivalents - we source from Owens Corning, Johns Manville, Knauf, and others with no proprietary lock-in.
6. 6
   Post-job verification and documentation. We run a second blower-door test, photograph the completed work, and deliver your Documented Photo Record with before-and-after numbers. The 365-Day Done Right Promise applies from that moment.

Why West Hollywood Homeowners Call Topside Attic Insulation West Hollywood for Owens Corning Work

We’ve been inside more than a few bungalows off Santa Monica Boulevard, and we know what a 1940s attic looks like when nobody’s touched it since the Carter administration. Our crew doesn’t blow insulation over an unsealed attic floor - we air-seal first, document the blower-door change, and hand you a written record.

The 365-Day Done Right Promise covers all completed work. Our technicians are background-checked and uniformed. Calls get answered by a live person, 24/7. We also service Reflectix and other major brands, so if your project involves multiple material systems, we don’t hand you off.

As an independent Owens Corning service provider, we’re not affiliated with or authorized by Owens Corning - we work for you, not the manufacturer.
