Fast, Reliable Attic Insulation Across Highgrove
If your Highgrove home still has the insulation it was built with, you’re paying for it every month. Attic insulation in Highgrove typically runs $1,200 – $2,800 for a standard single-story ranch, and the real cost of waiting is higher: Inland Empire summers push attic temperatures past 140°F, and that heat doesn’t stay in the attic. It radiates through your ceiling, makes your AC run constantly, and turns rooms on the west side of your house into ovens by 4 p.m. We’re North Tustin Insulation, an insulation-only contractor led by Allen Decker, and we work in Highgrove every week. Call (877) 265-5712 for a free estimate and we’ll tell you exactly what’s in your attic and what it should be.
Why North Tustin Insulation Is Highgrove’s Preferred Attic Insulation Company
We’re not a general contractor who does insulation on the side. Insulation is the entire job. That focus means we carry eight brands across fiberglass, cellulose, mineral wool, and spray foam – Owens Corning, CertainTeed, Rockwool, GreenFiber, Icynene, Demilec, Johns Manville, and Knauf – so the recommendation you get is based on what your Highgrove attic actually needs, not what happens to be on the truck that day.
Highgrove homeowners call us because their 1970s tract house has problems newer homes don’t. We know what a legacy foil radiant barrier looks like when it’s sagging. We know what R-11 batts look like after 50 years of getting crushed by stored Christmas decorations and ductwork. Allen Decker and our crew have walked through enough Highgrove attics off Columbia Avenue and Center Street to know the patterns before we even climb the ladder. That local experience shapes every estimate we give.
Attic Cleaning Services in Highgrove
Attic Cleaning Services in Highgrove start with what’s actually up there: decades of dust, rodent droppings, old insulation debris, and sometimes the remnants of a torn foil radiant barrier. Before any new insulation goes in, the attic floor needs to be clear enough to see what you’re working with. In a typical Highgrove ranch, that means removing old storage, vacuuming out dust and debris, and assessing the condition of whatever insulation is still in place. Cleaning alone typically runs $500 – $900 depending on attic size and how much debris needs to come out. If we’re cleaning as part of a full insulation upgrade, the cost folds into the larger job.
What Cleaning Unlocks
A clean attic exposes the problems you can’t see from the hatch. Cracked top plates. Gaps around can lights. Compressed batts that look fine from above but are doing nothing below. In Highgrove homes where original insulation has been walked on for 40 years, the compression alone can cut R-value by half. Cleaning isn’t prep work you can skip – it’s how you find out what the attic actually needs.
What We Remove
Old blown-in fiberglass that’s gone flat and dusty. Batts that have been shredded by rodents. Foil radiant barrier that’s torn and hanging. We bag it all, remove it through the attic access, and leave the space ready for whatever comes next. If you’ve got raccoon or rat sign up there, we’ll tell you before we seal it in.

Attic Mold Removal in Highgrove
Attic Mold Removal in Highgrove is a service we handle before insulation goes in – not after. Mold in a vented attic usually means something’s off with airflow: blocked soffit vents, bathroom fans exhausting into the attic instead of outside, or a roof leak that’s been slow-dripping for years. In Highgrove’s warm climate, mold doesn’t need much moisture to get started, especially in attics where old insulation is holding humidity against the wood. Mold removal in a Highgrove attic typically runs $800 – $2,500 depending on the affected square footage and whether the sheathing needs treatment or replacement. We inspect first, tell you what’s causing the moisture, then handle removal before we touch insulation.
When Mold Needs Addressing First
If you see dark staining on the underside of the roof deck or smell something musty when you open the attic access, do not just blow new insulation over it. Insulation won’t kill mold; it’ll trap it. In Highgrove’s older ranches, bathroom vents were sometimes terminated right into the attic space – a 1970s shortcut that’s still causing mold problems today. We fix the ventilation issue, treat the mold, and then insulate.
The Highgrove Ventilation Problem
Highgrove homes with gable vents but no soffit vents can run hot and humid at the same time. That combination is perfect for mold. When we handle Attic Mold Removal here, we look at the entire ventilation picture: soffit intake, gable or ridge exhaust, and whether anything’s blocking the airflow path. Adding insulation to a poorly vented attic just moves the moisture problem around.
Trusted Brands We Service in Highgrove
We install and upgrade Owens Corning fiberglass, GreenFiber cellulose, Icynene spray foam, and Demilec spray foam in Highgrove attics, plus the full lineup from CertainTeed, Rockwool, Johns Manville, and Knauf. Carrying multiple brands matters here because Highgrove’s housing stock isn’t uniform. A 1970s ranch with a sagging foil barrier needs a different approach than a 2015 infill house with an insulated roofline. We stock materials in the Inland Empire and schedule Highgrove jobs without making you wait on a slow supply chain. When you call (877) 265-5712, Allen Decker will tell you which brand actually fits your attic – not which one we’re trying to move this month.
Common Attic Insulation Problems We See in Highgrove Homes
- Legacy foil radiant barriers from 1970s tract builds. Those shiny sheets stapled to the rafters were meant to reflect radiant heat, but after 50 years they sag, tear, and collect a layer of dust that kills their reflective ability. The heat gain returns even after you add new insulation, because the barrier above it is no longer doing its job.
- Original R-11 batts that have given up. Builders in Riverside County put the minimum in, and the minimum back then was thin. After decades of being walked on, compressed by boxes, and settled by gravity, those batts are doing a fraction of what they did when new. Summer attic heat drives straight through the thin spots.
- Unsealed top plates and can lights. Insulation only works if air can’t flow around it. The seams along wall top plates and the gaps around recessed lighting cans act like open windows from the attic into your living space. Highgrove homes with original construction are full of these bypasses.
- Crushed and settled blown-in insulation. Even if a previous owner topped up the attic at some point, blown-in fiberglass or cellulose loses loft and R-value as it settles over time. In Highgrove’s dry climate, the material isn’t wet – it just gets flat and tired.

FAQs About Attic Insulation in Highgrove
Yes, but only after we evaluate its condition. If the foil is still tight and reasonably clean, we can work around it and add insulation on the attic floor without touching the barrier. If it’s torn, sagging, or dust-caked, it’s doing nothing for you and we’ll recommend removing or replacing it before you spend money on new insulation. The radiant barrier and the floor insulation work together in Highgrove’s climate – you need both functioning to actually cut attic heat gain. Call (877) 265-5712 and we’ll look at what’s stapled to your rafters.
Highgrove attics routinely hit 130°F to 150°F on summer afternoons, and the heat builds fast once the sun clears the eastern hills. That’s why we schedule attic work for early morning starts in the warm months – by 10 a.m. the space can already be dangerously hot for a crew to work in safely. We complete the most physically demanding attic work before the heat peaks, which also protects the materials. Spray foam and adhesives perform differently in extreme heat, so an early start gives you a better install.
If your original R-11 batts are dry, intact, and not compressed beyond recognition, a top-up can get you to a proper R-value for Highgrove’s climate. But in most 1970s-era Highgrove homes we open up, the batts are so compressed and degraded that topping them up means piling new insulation on a broken base. We’ll tell you honestly which path makes sense after we inspect. The answer changes house to house, and we won’t sell you a full replacement if a top-up does the job.
Yes – we do attic mold removal as part of the full insulation job. We won’t blow new insulation over active mold or over the moisture source that caused it. In Highgrove homes, the culprit is usually bathroom exhaust venting into the attic or inadequate soffit ventilation. We correct the airflow, treat the mold, and only then install the new insulation. It’s the only order that makes sense.
We install Owens Corning fiberglass, GreenFiber cellulose, Icynene spray foam, Demilec spray foam, and products from CertainTeed, Rockwool, Johns Manville, and Knauf. We match the brand to your attic’s needs – a tight attic with awkward access might call for blown-in GreenFiber, while an attic with ductwork running through it might call for Owens Corning batts. You get a real recommendation, not a brand pitch. Call (877) 265-5712 and Allen Decker will walk you through the options.
