Reflectix Insulation in San Gabriel, CA | Laguna Hills Insulation
We provide independent Reflectix installation and repair across San Gabriel, CA, and the one thing that separates our work here is the pre-installation moisture check we run on 91775 crawl spaces before we touch an attic. San Gabriel’s shallow subfloor cavities hold water after rain, and that hidden dampness quietly ruins radiant barrier performance if nobody looks first. We’re the crew that looks. Call (866) 393-6041 for a free estimate, and we’ll walk your property the way it actually needs to be walked.
Almost every San Gabriel homeowner we meet has a 1940s – 1970s wood-frame house with a hot attic and no idea whether the foil they’re considering will hold up. We know Reflectix because we’ve installed and diagnosed it in hundreds of San Gabriel Valley homes, from flat stucco ranch houses to Spanish-revival bungalows near San Gabriel Mission. No manufacturer authorization is claimed or implied. What we offer is honest, material-grounded judgment, paired with genuine Reflectix products and compatible foil tapes. Our Reflectix sales & service work covers repair, replacement, and new installation, and we serve San Gabriel service area ZIP codes 91775, 91776, and 91778.
Why San Gabriel Residents Choose Us for Reflectix Service
Most insulation contractors in the San Gabriel Valley push whatever product line they stock. We carry eight manufacturer brands across fiberglass, mineral wool, spray foam, and reflective insulation, because we’d rather match the material to your house than force a sale. Reflectix is a specific tool, and it earns its place in certain San Gabriel attics, not all of them. The right material in the right place does the work. Everything else is just sales pitch.
Garrett Lund, our owner, grew up in Laguna Hills and learned building science at Saddleback College’s construction technology program. He’s spent over two decades figuring out how structures breathe, hold heat, and lose it, which is why our approach to Reflectix in San Gabriel starts with air sealing and ventilation before foil ever touches a rafter. When you call, you get someone who can explain R-value and radiant heat transfer without talking down to you.
Common Reflectix Insulation Problems We Solve in San Gabriel
- Foil delamination on roof-deck radiant barriers. San Gabriel’s low, trussed attic spaces trap heat, and when ventilation is inadequate, the adhesive layer on Reflectix bubble pack separates and bubbles. We see this constantly in post-war tract homes where the original gable vents were sealed during reroofs. The fix is removing the failed foil, adding baffles, and stapling new Reflectix with an air gap, not gluing it back.
- Condensation and moisture damage in shallow crawl spaces. The 91775 ZIP has bungalows with subfloor cavities barely tall enough to crouch in. After any rain, those spaces hold moisture that wicks into framing. Reflectix stapled against joists without a vapor barrier becomes a condensation trap. We check for dampness first, then decide whether the crawl space needs encapsulation before any reflective insulation goes in.
- Dust accumulation killing reflectivity. In San Gabriel’s dry summers, attics get dusty. Reflectix installed directly on the attic floor without an air gap collects that dust, and a dirty foil surface conducts heat instead of reflecting it. We clean and refasten where possible, and re-install with proper spacing where it isn’t.
- Tape failure at seams. Reflective foil tape in San Gabriel attics sees temperatures well over 120°F in July and August. Cheap tape lifts at the edges, seams separate, and the radiant barrier stops being a barrier. We use genuine Reflectix Insulation Tape and compatible high-temperature foil tapes, pressed and sealed properly on every seam.
- Improper installation from previous contractors. We regularly find Reflectix draped over attic insulation like a blanket, which defeats the entire reflective principle. Radiant barrier needs an air gap facing the heat source. We re-staple it to rafters or the roof deck, where it actually works.
Reflectix Service in San Gabriel: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Reflectix guide. The 91775 portion of San Gabriel is dense with 1950s bungalows sitting on shallow subfloor crawl spaces. After even a light rain, those cavities hold moisture that wicks into uninsulated floor framing and rises through the structure. A contractor who blows insulation or staples radiant barrier without checking below the house is solving the symptom, not the source. We learned this the hard way on a job near San Gabriel Mission, where a homeowner called us about peeling attic foil, and the real problem was a damp crawl space feeding humidity into the attic all summer. We now perform a moisture sniff test on every San Gabriel job before we recommend or install anything. It takes ten minutes. It changes the outcome.
We recently installed a Reflectix radiant barrier in a 1955 Spanish-revival bungalow near San Gabriel Mission. The attic had no existing insulation, and the roof deck was baking. We sealed air gaps, added baffles for ventilation, and stapled Reflectix foil to the rafters with a proper air gap. Attic temperatures dropped by about 20°F, and the homeowner noticed the second floor was cooler within a day. That’s the sequence that works: air seal, ventilate, then reflect.
Reflectix Models & Products We Service in San Gabriel
Our San Gabriel crews work with the full Reflectix lineup. That includes Reflectix Double Reflective Insulation Roll, the bubble pack variant used on attic rafters and ducting; Reflectix Reflective Foil Insulation, the single-bubble product suited for lighter applications; Reflectix Radiant Barrier Attic Foil, the reinforced product we recommend for roof-deck applications; and Reflectix Insulation Tape, the foil tape we use on every seam. We match the original product type and thickness when repairing existing installations, and we stock these lines locally for fast San Gabriel turnaround. When Reflectix is degraded beyond repair, we’ll tell you straight, and we’ll recommend either new Reflectix or a hybrid approach, like radiant barrier paired with blown-in fiberglass or cellulose from our broader Reflectix sales & service work.
Reflectix Service Pricing in San Gabriel
Reflectix installation in San Gabriel generally runs between $1.50 and $3.00 per square foot for materials and labor, depending on whether we’re working on rafters, a roof deck, or a crawl space. A typical 1,200-square-foot attic radiant barrier job lands in the $1,800 to $3,600 range. Repair work, like resealing tape seams or refastening sagging foil, usually starts around $250 and goes up based on how much failed material needs removal. What drives the cost in San Gabriel specifically is attic access, the condition of existing insulation, and whether we find moisture that needs addressing first.
Every estimate is free, and it includes the crawl space check. Call (866) 393-6041 and we’ll give you an exact number for your house, not a ballpark from a brochure.

FAQs – Reflectix Insulation in San Gabriel
Does Reflectix radiant barrier work well in San Gabriel’s hot, dry climate?
Yes, Reflectix performs well in San Gabriel’s hot, dry summers, provided it’s installed with an air gap facing the heat source and paired with adequate attic ventilation. The valley sees summer heat spikes well above downtown L.A., and a properly stapled radiant barrier on the roof deck or rafters reduces attic temperatures by 15 to 25°F. Without ventilation, however, the foil traps heat and fails. Call (866) 393-6041 and we’ll assess your attic before recommending anything.
Can I install Reflectix over existing attic insulation?
No, and this is a common mistake we see in San Gabriel attics. Laying Reflectix over blown-in insulation or batts eliminates the air gap that makes reflective insulation work, turning it into a conductive layer that holds heat. Reflectix goes on rafters, the roof deck, or knee walls, not on top of loose fill. We can tell you in five minutes whether your attic is a candidate.
What should I do if my Reflectix foil is peeling or bubbling?
Peeling or bubbling foil means the adhesive layer has failed, usually from trapped heat in a low, trussed attic with poor ventilation. Do not try to glue it back. The failed section needs to be removed, the ventilation corrected, and new Reflectix stapled in with an air gap. We handle this regularly in San Gabriel’s post-war tracts, and we can usually complete the repair same day. For an exact price, call (866) 393-6041.
Do you check crawl spaces before installing Reflectix in the attic?
Always, in San Gabriel’s 91775 ZIP especially. The shallow crawl spaces under many 1950s bungalows hold moisture after rain, and that moisture rises into the attic and undermines any radiant barrier we install. We check for dampness, recommend a vapor barrier if needed, and only then proceed with attic work. It’s a ten-minute step that saves you from a failed installation.
Is Reflectix a good choice for crawl space insulation in San Gabriel?
Reflectix can work in dry crawl spaces, but San Gabriel’s shallow subfloor cavities are often damp after rain, and reflective foil installed without a vapor barrier becomes a condensation trap. For most 91775 homes, we recommend a proper crawl space vapor barrier and, in some cases, closed-cell spray foam on the rim joists. We’ll tell you honestly whether Reflectix fits your crawl space or whether another material is the right call. Estimates are free, so call (866) 393-6041 and we’ll take a look.
