This page is for West Covina homeowners who already have Icynene in their walls or attic and suspect something’s off, or who are weighing Icynene against other spray foam brands. You’ll find straight answers on what these systems cost here, how they fail, and what a real fix looks like.

How Icynene Products Fail - and How We Fix Them

Icynene made its name with Classic open-cell foam, then expanded into closed-cell lines like ProSeal and MD-C-200. Each has its own weak spots in the West Covina climate, and we’ve pulled enough of it out of attics to know the failure patterns cold.

• Classic and Classic Max open-cell shrinkage. Open-cell Icynene can pull away from stud bays over time, especially in older West Covina homes where the framing flexes with our hot summers and cool winters. The foam detaches from the sheathing and you lose the air seal. We cut back the failed section, re-insulate with fresh open-cell, and re-dress the area to match.
• ProSeal closed-cell over-application. Closed-cell Icynene expands aggressively. When an installer puts it on too thick in one pass, it can distort wall cavities or even bow drywall. We’ve seen this in homes near the Eastland Center corridor where quick flips got cheap foam jobs. The fix is cutting back the excess, checking framing alignment, and re-applying in proper lifts.
• Rim joist foam that never cured right. Spray foam in rim joists needs the substrate temperature within the manufacturer’s window. In unheated crawl spaces in West Covina, winter mornings can put the rim joist below spec, and the foam cures crumbly instead of solid. We test the existing foam, remove anything that didn’t cure, and re-spray when conditions are right.
• Garage ceiling foam with poor adhesion. Icynene on painted or dusty garage ceilings can lose its mechanical bond within a few years. We wire-brush the surface, check for moisture, and re-apply with the correct primer or surface prep the original installer skipped.
• Odor complaints from improper mix. Several Icynene lines use a two-part A/B chemical system. If the installer’s equipment runs the wrong ratio or temperature, the foam can off-gas for weeks or months. We identify the misfire, remove the bad section, and re-spray with calibrated equipment.

One thing we often tell homeowners: Icynene hasn’t made the Classic line under that name for years. If your house has “Classic” foam from the early 2000s, it may be underperforming simply because open-cell foam settles and loses R-value with age. That’s worth a look before you pour money into a new HVAC system.

Our Icynene Spray Foam Insulation Process

Here’s how a typical Icynene job goes with our crew, from first call to final walkthrough:

1. 1
   Call and schedule. You call (626) 612-1532. A live person answers, even at 2 a.m. We ask a few questions about your house and set a visit time that works.
2. 2
   Onsite inspection. A background-checked, uniformed tech walks the attic, walls, or crawl space, checks the existing foam (if any), looks for air leaks, and takes moisture readings where it matters.
3. 3
   Straight recommendation. We tell you what’s wrong, what needs replacing, and whether open-cell or closed-cell foam makes sense for that specific space. If something doesn’t need fixing, we say so.
4. 4
   Prep and application. We mask off the work area, prep the substrate properly, and apply the foam in correct lifts using calibrated equipment. Clean lines, correct depth, no shortcuts.
5. 5
   Inspection and cleanup. We check thickness, adhesion, and coverage, then clean up so you’d never know we were there except for the improved comfort.
6. 6
   Done Right Promise. Every job is covered by our lifetime workmanship guarantee. If it’s not done right, we make it right. No runaround.

What Icynene Spray Foam Insulation Costs in West Covina

Here’s what Icynene work typically runs in West Covina, as of 2026:

• Open-cell spray foam (attic or wall): $1.50 to $2.50 per board foot, installed.
• Closed-cell spray foam (rim joists, roof deck, or crawl space): $2.50 to $3.50 per board foot, installed.
• Rim joist foam package (typical 2,000 sq ft house): $2,400 to $4,800.
• Spray foam roof deck (standard attic, West Covina ranch-style): $7,000 to $14,000.
• Garage ceiling foam (single car, detached): $900 to $1,800.
• Partial removal and re-spray of failed foam: $2,500 to $7,500, depending on access and depth.

What moves the price: access (cramped attics add labor), condition of existing insulation, closed-cell versus open-cell, and depth requirements. Closed-cell runs more per board foot but delivers roughly double the R-value per inch. We give upfront pricing before any work starts, and you get a free second opinion on any written estimate you’ve received from someone else. Call (626) 612-1532 for an exact number.
