Insulation Company in Murrieta Hot Springs, CA
Blown in insulation is the fastest way to restore thermal performance in Murrieta Hot Springs homes where original fiberglass batts have settled, compressed, or were never adequate for the valley’s summer heat. Most of the tract houses here were built between the 1980s and 2000s, and their attics still hold R-11 or R-19 material that was code minimum at the time. We match loose fill fiberglass or cellulose to the existing thermal boundary, and you can reach Fontana Insulation at (866) 271-1602 for a free assessment of what’s actually up there.
Why Murrieta Hot Springs Homes Are Different
Murrieta Hot Springs sits in an inland valley where July and August temperatures routinely cross 100°F, and attic temperatures climb well past 150°F during the same stretch. The housing stock reflects two distinct building eras: the 1980s sections off Murrieta Hot Springs Road where original R-11 batts are often compressed under decades of dust, and the 2000s tracts where blown in insulation has settled below the top of the ceiling joists. Both conditions produce the same result: an air conditioner that runs constantly while upstairs rooms stay warm.
Winter adds a second demand. Mornings near freezing are common from December through February, which means the insulation needs to perform in both directions. The wood frame, two story tract construction typical of 92563 responds well to loose fill material because it can be blown to a uniform depth across irregular joist spacing and around recessed cans. Santa Ana winds in the fall also push dust and heat through any gaps in the attic floor, so air sealing goes hand in hand with the insulation work here.
One pattern we see consistently in Murrieta Hot Springs is that homeowners discover their insulation problem only when the first 100°F week of July arrives and the AC can’t keep up. By then the attic has been baking for weeks, and the existing material has already lost much of its effective R-value. The good news is that blown in insulation can often be installed in a single day, which means the fix doesn’t have to wait for cooler weather.
Our Main Murrieta Hot Springs Services
The two services Murrieta Hot Springs homeowners call about most are attic insulation and spray foam, each addressing a different problem in the local housing stock.
Attic Insulation in Murrieta Hot Springs
Attic work in Murrieta Hot Springs usually means bringing a 1980s or 2000s tract home up from builder grade to something that actually holds back 150°F attic air. We inspect what’s already up there, remove or top off settled material, and install to current R-value targets for our climate zone. The most common scenario is adding blown in fiberglass or cellulose over compressed original batts. For a full rundown on how attic jobs work here, see Attic Insulation in Murrieta Hot Springs.
Spray Foam Insulation in Murrieta Hot Springs
Spray foam earns its place in Murrieta Hot Springs homes where air movement is the real culprit: cantilevered floors over garages, knee walls in bonus rooms, and rim joists in crawlspaces. Closed cell foam also adds structural rigidity, which matters in two story wood frame construction. We install Icynene and Demilec open and closed cell products for homeowners who want air sealing as much as thermal resistance. Details are on Spray Foam Insulation in Murrieta Hot Springs.

Blown In Insulation in Murrieta Hot Springs
Blown in insulation in Murrieta Hot Springs is the standard answer for attics where original batts have settled, compressed, or never met the thermal demands of an inland valley summer. We install loose fill fiberglass and cellulose because both materials can be blown to a consistent depth over existing insulation, filling the gaps and low spots that batts leave behind. This approach works especially well in 1980s and 2000s tract homes where joist spacing is uneven and retrofit work has disturbed the original material. Fontana Insulation carries Knauf, CertainTeed, and GreenFiber products for Blown In Insulation work, so the material choice follows the home’s condition rather than what’s on the truck.
Loose Fill Insulation
Signs you need it
If your upstairs rooms run 8 to 10 degrees warmer than downstairs during summer, or you can see the tops of ceiling joists in the attic, the loose fill has settled below its rated depth.
What it costs in Murrieta Hot Springs
Loose fill insulation in Murrieta Hot Springs typically runs $1.50 to $3.50 per square foot installed, depending on material type, target R-value, and existing material condition.
How we do it
We air seal the attic floor penetrations first, then blow loose fill fiberglass or cellulose to a uniform depth that meets the R-value target for our climate zone.
Blown In Attic Insulation
Signs you need it
High cooling bills, hot ceilings, and attic temperatures above 150°F in July are the three most common indicators in Murrieta Hot Springs homes.
What it costs in Murrieta Hot Springs
Blown in attic insulation in Murrieta Hot Springs typically falls between $1,800 and $4,500 for a standard two story tract home, with the range driven by square footage and current R-value.
How we do it
We remove or top off the existing material, seal the attic floor, and blow the new insulation to full depth across the entire ceiling plane, including over the garage.
Blown In Cellulose Insulation
Signs you need it
Cellulose is the right call when you want recycled content and better sound dampening between floors, and the existing attic material has settled past its useful depth.
What it costs in Murrieta Hot Springs
Blown in cellulose runs $1.75 to $3.75 per square foot installed in Murrieta Hot Springs, which reflects GreenFiber material and the density needed to hit R-38 or R-49.
How we do it
We dense pack or loose blow GreenFiber cellulose to the specified depth, with special attention to the perimeter eaves where heat gain is greatest.
Blown In Fiberglass Insulation
Signs you need it
Blown in fiberglass suits Murrieta Hot Springs attics where the existing batts are fiberglass and you want to add material without changing the insulation type.
What it costs in Murrieta Hot Springs
Blown in fiberglass in Murrieta Hot Springs costs $1.50 to $3.25 per square foot installed, with Knauf and CertainTeed products both available for the job.
How we do it
We blow the fiberglass to the target depth, then level it with a conditioning rake so the final R-value is uniform wall to wall.
What Blown In Insulation Costs in Murrieta Hot Springs
| Item | Typical range in Murrieta Hot Springs |
|---|---|
| Blown in attic insulation (standard 1,800 sq ft attic) | $1,800 – $4,500 |
| Blown in fiberglass (per sq ft installed) | $1.50 – $3.25 |
| Blown in cellulose (per sq ft installed) | $1.75 – $3.75 |
Is blown in insulation worth it in Murrieta Hot Springs?
Yes, especially in homes built before 2005 with original R-11 or R-19 material. Bringing the attic to R-38 or R-49 directly reduces the AC load during 100°F summer days.
Can you blow insulation over old batts in Murrieta Hot Springs?
In most cases, yes. We blow loose fill directly over settled fiberglass batts after air sealing. The exception is when the old material is wet, pest damaged, or compressed to the point where removal makes more sense. Call (866) 271-1602 and we’ll tell you which applies.

What Murrieta Hot Springs Customers Say
"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Nadia Aziz"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
