Fast, Reliable Spray Foam Insulation Across Hemet
Spray foam insulation in Hemet typically costs $1,800 – $4,600 for a closed-cell attic application on a standard 1,500 sq ft ranch, and we usually have a crew on-site within 24 – 48 hours of your call. Those numbers matter if you’re sitting in a Hemet house that won’t cool below 80°F in July. We’re Laurel Attic Insulation, part of the Relay Home Co. family, and we work on Hemet attics every week, from older tracts near Florida Avenue to newer builds off Sanderson. Call (361) 315-4177 and we’ll give you a written price before anything starts, not a vague estimate.
Why Laurel Attic Insulation Is Hemet’s Preferred Spray Foam Insulation Company
Hemet homeowners keep calling us because we show up when we say we will and we put prices in writing. Our techs know the difference between a 1970s ranch off Kirby Street and a 2000s two-story near the Hemet Valley Mall, and they treat each one differently. We also carry materials from Owens Corning, Johns Manville, and Rockwool, so the foam going into your attic isn’t whatever happened to be on the truck that morning. Every job includes the Relay Visibility Guarantee: a live arrival time, before-and-after photos sent to your phone, and a written price before work starts.
We were called to a 1978 ranch house near the intersection of Florida Avenue and Kirby Street in Hemet where the homeowner complained the back bedrooms never cooled below 80°F even with a new 4-ton AC. Our tech found R-13 batts slumped off the rafters in the west-facing attic, with daylight visible through the deck seams. We removed the failed batts and applied 2 inches of closed-cell spray foam (Icynene) to the roof deck and gable ends, then flashed the top plates; the homeowner reported a 12°F drop in the back bedrooms the first afternoon. That’s the kind of result we can repeat in hundreds of Hemet homes.
Chase Whitaker leads our crew, and he’s the one who answers when a Hemet customer asks why the west side of the house is always 10 degrees hotter. The 365-Day Done Right Promise backs every job in writing: if it isn’t right within a year, we make it right, and a second visit is free if the repair fails.
Closed Cell Spray Foam Insulation in Hemet
Closed Cell Spray Foam Insulation is the one we recommend for most Hemet roof decks because it adds structural strength and stops the dust and air infiltration that the Elsinore gap winds push through your attic seams. Hemet sits in a high-wind, low-humidity zone east of that gap, and west-facing roof planes take the brunt of afternoon sun and Santa Ana-style winds. Closed-cell foam at 2 inches gives you about R-14 and acts as an air barrier, which no batt can do. A typical closed-cell attic job in Hemet runs $2,800 – $4,600 depending on square footage and whether we’re doing gable ends, top plates, or the full roof deck.
West-Facing Roof Decks
The west wall of your attic is the one that gets hammered every afternoon. Closed-cell foam on that deck plane stops the wind-driven heat and dust that open-cell can’t handle when it’s applied too thin. We see this pattern constantly in Hemet’s older neighborhoods near McSweeny Farms and east of Cawston Avenue.
Rim Joists and Top Plates
Air leaks through top plates and rim joists are the hidden reason Hemet homes stay hot even after attic insulation is replaced. Closed-cell foam seals those gaps permanently, which is why we flash them on every closed-cell job here.
Open Cell Spray Foam in Hemet
Open Cell Spray Foam is the quieter, more affordable option for interior walls and ceilings in Hemet homes where dust and noise from outside are the bigger problems. It expands aggressively and fills every cavity, which makes it a strong choice for second-story bedrooms over garages or bonus rooms near Menifee Road. A typical open-cell application in Hemet runs $1,800 – $3,200. One caveat specific to Hemet: open-cell foam can shrink at deck seams on west-facing roof planes if it isn’t applied thick enough, so we usually steer those jobs toward closed-cell instead.
Garage Ceilings
Hemet garages attached to living space leak hot air upward into bedrooms. Open-cell foam on the garage ceiling slows that transfer and quiets the room below the attic at the same time. It’s a two-for-one fix we do often in the newer tracts east of Sanderson.
Interior Sound Control
If you live near the railroad corridor or the 74, open-cell foam in interior walls takes the edge off traffic and train noise while insulating at the same time. Hemet homeowners close to the Esplanade shopping area ask for this often.
Trusted Brands We Service in Hemet
We stock and install materials from Owens Corning, Johns Manville, and Rockwool, which means the foam going into your Hemet attic is professional-grade and matched to your specific roof deck, not just whatever fits the truck route that day.

If you already have a brand preference, say so when you call (361) 315-4177 and we’ll tell you honestly whether it’s the right fit for your attic’s orientation and age.
Common Spray Foam Insulation Problems We See in Hemet Homes
- Sagging batts in 1960s – 80s tract homes. Hemet’s summer attic cycles hit 140 – 150°F repeatedly, and after 10 – 15 years the fiberglass batts lose contact with the rafters. The insulation is still there, but it’s doing almost nothing, and the convection loop makes the house feel hotter than the thermostat says.
- Shrinking open-cell foam on west-facing decks. Wind-driven heat and dust from the Elsinore gap can dry out thin open-cell foam at the deck seams. If it wasn’t applied thick enough, the foam pulls back from the wood and air leaks return within a few years.
- Dust intrusion through unsealed top plates and can lights. This is a big one in Hemet’s older neighborhoods. You can replace all the attic insulation and still feel dusty, hot air coming through the ceiling because nobody sealed the gaps around light fixtures and wall plates first.
- Daylight visible through deck seams on older roof decks. In the 1970s ranches off Kirby and Florida, the roof decking often has visible gaps between boards. No batt can fix that. Closed-cell foam bridges those seams and acts as an air barrier, which is why it’s the right call in most of these houses.

FAQs About Spray Foam Insulation in Hemet
Hemet sits in an inland valley where summer attics regularly reach 140 – 150°F. That heat cycling, year after year, makes fiberglass batts sag and lose contact with the rafters, which is why spray foam’s air-sealing outperforms batts in this specific climate. If your batts are more than 10 years old, they’re probably already failing. Call (361) 315-4177 and we’ll do a free attic inspection and tell you honestly what’s still working.
Closed-cell, in almost every case. West-facing roof planes in Hemet take the afternoon sun and Santa Ana-style winds, which can shrink open-cell foam at the deck seams if it isn’t applied thick enough. Closed-cell adds an air barrier and structural strength; it costs more upfront but lasts far longer on the side of the house that does the most work.
We can usually have a technician at your Hemet home within 24 – 48 hours, and for emergency failures like a collapsed attic floor section or a major air leak, same-day dispatch is often possible. Our dispatch runs from the Inland Empire office, so Hemet is a regular part of our service area, not a far-flung add-on. Call (361) 315-4177 and we’ll lock in a time.
No, and we’d never do that. You can’t get proper adhesion over old batts. We remove the failed insulation first, inspect the deck seams and top plates, then apply the spray foam directly to the clean surface. On a 1970s Hemet ranch, that usually means pulling out R-11 or R-13 batts and applying closed-cell foam to the roof deck for a real air seal.
Yes. Homeowners we’ve served in Hemet report 10 – 15°F drops in room temperature after closed-cell foam is applied to the attic, which means the AC runs fewer hours and the west-facing bedrooms finally cool down. Every house is different, but the air-sealing alone usually cuts cooling costs 15 – 25% in Hemet’s summer climate. Call (361) 315-4177 for an honest assessment of your house.
