Insulation Company in Sunnyslope, CA
Blown in insulation solves the single biggest problem facing Sunnyslope homeowners: attics that bake in 100°F+ summers and bleed heat all winter because the original insulation settled decades ago. Most homes in the 92509 ZIP were built between the 1950s and 1980s, and many still have the same thin, compressed material they had when they were first framed. Thermal Insulation Co has served Sunnyslope since 2012, bringing attics up to current standards with blown-in loose fill that fills every cavity without disturbing ceilings or walls.

Why Sunnyslope Homes Are Different
Sunnyslope sits in the Jurupa Valley, far enough inland that the ocean breeze rarely reaches it. Summer highs routinely push past 100°F, and attics here commonly hit 150°F by mid-afternoon. That heat soaks through the ceiling into living spaces, forcing air conditioners to run for hours just to hold a comfortable temperature. The housing stock compounds the problem. Most Sunnyslope homes are mid-century tract houses and single-story stucco builds from the 1950s through the 1980s. Their original attic insulation was often R-11 or R-19 fiberglass batts, now flattened by decades of foot traffic from plumbers and electricians, contaminated by roof leaks, or simply never adequate for this climate. Current Title 24 standards call for R-38 in most attics, a gap that shows up on every July electric bill. Technicians working in Sunnyslope focus on upgrading older attics, not insulating new construction, because that is where the homes are and where the energy loss is most severe.
Our Main Sunnyslope Services
Most Sunnyslope homeowners call us about two things: attic insulation that has stopped doing its job, and spray foam for hard-to-reach or hard-to-condition spaces. Both are covered below.
Attic Insulation in Sunnyslope
Sunnyslope attics are hot, tight, and often full of surprises: old wiring, vermiculite, roof patches, and settled batts that look thicker than they really perform. Our attic work starts with an inspection of what is already up there, then an air-sealing pass to close the gaps that let conditioned air escape. For most Sunnyslope homes, the fix is a full removal of degraded material and a fresh blow-in or batt install to R-38 or better. We match the material to the attic: blown-in for tight, irregular cavities, batts for open rectangular bays. Attic Insulation in Sunnyslope covers the full process, from inspection to cleanup.
Spray Foam Insulation in Sunnyslope
Some Sunnyslope homes have attics with ductwork running through them, or knee walls, or cathedral ceilings where batt and blown-in simply cannot reach. Spray foam is the answer there. Closed-cell foam adds structural strength and a full air seal, while open-cell foam is a more forgiving fit for some roof decks and wall cavities. The extreme heat here makes air sealing critical: the same gaps that let hot air in during summer let cooled air out all afternoon. For attics with HVAC equipment, foam can make a measurable difference in how long the system runs. Spray Foam Insulation in Sunnyslope explains when each foam type makes sense.

Blown In Insulation in Sunnyslope
Blown in insulation is the most common upgrade we install in Sunnyslope because it fits the attics here so well. Most homes in this part of the Jurupa Valley have attics with odd angles, low clearance, truss webs, and ductwork running everywhere, and blown-in loose fill flows around all of it to create a continuous thermal blanket. Whether it is cellulose or fiberglass, the material fills the gaps that batts leave open, and that matters in a climate where attic temperatures swing from 150°F in August to near freezing on winter nights. For more on our capabilities, see Blown In Insulation.
