Insulation Company in Fontana, CA
Woolsey Attic Insulation handles attic insulation and spray foam work throughout Fontana, CA. Most Fontana homes fall into one of two camps: pre-1980 tract builds with degraded fiberglass batts and compacted blown-in cellulose, or newer 2000s construction that met code minimums but still struggles with 100°F-plus summers. That mix means every job starts with a real look at what’s actually up there, not a guess. Call us at (831) 263-0387 and we’ll walk you through what your attic needs, in plain language, before any work is scheduled.
Why Fontana Homes Are Different
Fontana’s housing stock spans a wide range of eras, and that changes what we find in attics. Homes built from the 1950s through the 1990s dominate much of the city’s established neighborhoods. Many still have original fiberglass batts that have settled, compressed, or been torn apart by rodents over the years. We regularly open attic hatches in older Fontana homes and find blown-in cellulose that has compacted to half its original R-value, leaving the ceiling doing almost none of the work it should. Meanwhile, the newer developments from the 2000s and later, especially in the north end and areas south of the 10, were often built to code minimums. That’s legal, but it’s not comfortable in an Inland Empire attic that hits 140°F in August. Attic access hatches are another recurring issue across Fontana: many are uninsulated, acting like an open window between the conditioned house and the furnace-like attic above it. Add in Fontana’s dry heat, cool winters that dip toward frost on clear nights, and Santa Ana wind events, and the case for properly sealed, correctly rated insulation makes itself.
Our Main Fontana Services
Two services account for nearly every call we take from Fontana homeowners. Each one has its own page with full pricing, local conditions, and a breakdown of how the work runs. Here’s where to start.
Attic Insulation in Fontana
Attic insulation in Fontana usually means one of two things: replacing old, degraded fiberglass batts or blown-in insulation that has settled over decades, or topping up newer homes that were built to minimum code and now pay for it every summer. In Fontana’s older ranch and two-story stucco homes, attics with poor ventilation trap heat and bake whatever insulation remains. We inspect the existing material, measure current depth, and recommend either full removal and replacement or a targeted top-up, whichever fits the condition of the attic. For a full breakdown of what attic insulation costs and how the job runs in Fontana, visit Attic Insulation in Fontana.
Spray Foam Insulation in Fontana
Spray foam insulation, a two-part liquid that expands on contact and seals gaps airtight, works especially well in Fontana attics where air leakage drives up cooling costs through the long hot season. Open-cell and closed-cell options each have their place, depending on your roofline, attic ventilation setup, and budget. For many Fontana homes with unvented attics or attic access hatches leaking conditioned air, spray foam delivers the air-sealing performance that batt insulation alone cannot match.

What Fontana Customers Say
"Insulation job was done well. Scheduling took a little longer than I'd have liked, they were booked out a couple weeks. But once they came it was quick and the house is cozier."
- Felicia Grant"Our old insulation was flattened and basically useless. They removed it, cleaned up, and blew in new. Furnace isn't running constantly anymore and the first bill already showed it."
- Carl Yeung"Upstairs was always ten degrees hotter than downstairs in summer. They added attic insulation and the difference is night and day. Written price up front, no add ons at the end."
