Reflectix Insulation in San Francisco, CA | Aspen Attic Insulation
Reflectix insulation service in San Francisco typically costs $2.50 to $6.00 per square foot installed, depending on whether you need attic radiant barrier, crawl space work, or a full wall-cavity retrofit. We’re Aspen Attic Insulation, an independent contractor serving San Francisco with San Francisco Attic Insulation services using genuine Reflectix products and a written price before any work starts. The thing that separates our Reflectix work here: we understand how marine-layer dampness in neighborhoods like the Outer Sunset and Richmond changes how this foil performs, and we install accordingly. Call (864) 428-1615 for a free estimate.
Our team has installed Reflectix double reflective rolls, radiant barriers, and duct wraps across San Francisco’s Victorian flats, Edwardian row houses, and postwar Sunset district homes. Reflectix makes a low-profile foil and bubble-pack product that fits tight attic cavities and crawl spaces where fiberglass batts won’t cooperate. We stock it, we cut it, we tape it, and we stand behind the install for 365 days. Reflectix sales & service is a core part of what we do, but our real specialty is knowing when this product is the right call in San Francisco and when it isn’t.
Why San Francisco Residents Choose Us for Reflectix Service
Garrett Sloane built Aspen Attic Insulation on a simple rule: show up on time, tell the homeowner exactly what you found, and fix it right the first time. He learned the trade through the construction technology program at Los Angeles Trade-Technical College, then spent years in attics and crawl spaces before going out on his own. That experience matters here because San Francisco homes throw curveballs: balloon framing, knob-and-tube wiring, zero sheathing, and fog that never quite leaves.
We’re not authorized or sponsored by Reflectix, and we’ll tell you that plainly. What we are is experienced with their product line, and we choose it when the job calls for a vapor-open, low-profile radiant barrier that won’t chew up what little cavity space a 1905 Edwardian gives you. Every technician we send to your San Francisco home is background-checked, uniformed, and photo-badged. You get the tech’s name and photo before anyone knocks. If someone else shows up, the visit is free. That’s the Threshold Standard, and we’ve held to it since 2002.
You’ll know the price before we pull the hatch.
Common Reflectix Insulation Problems We Solve in San Francisco
- Foil delamination in fog-belt crawl spaces. In the Outer Sunset, marine-layer dampness sits on everything. We regularly find Reflectix where the foil layer has started peeling away from the bubble core because it was installed tight against a damp surface with no air gap. We pull the damaged runs, check what’s behind them, and reinstall with proper venting.
- Crushed bubble pack in Victorian wall cavities. San Francisco’s balloon-framed Victorians have odd stud bays, sometimes only 2.5 to 3.5 inches deep. When Reflectix gets stuffed or compressed into those gaps, the trapped-air pockets collapse and the radiant barrier loses most of its performance. We cut it to fit without compression, or we tell you honestly when a different product makes more sense.
- Moisture trapped against old stucco in the Sunset and Richmond. Postwar stucco boxes often lack sheathing. Reflectix installed directly against the stucco backside traps moisture, leading to mold on the foil face and rusted staples. We see this constantly in the avenues. The fix is an air gap and a vapor-open assembly, not just more tape.
- Clogged perforations in unvented attics near the fog belt. Perforated Reflectix gives vapor a way out, but in San Francisco attics where dust and fine marine particles accumulate, those perforations clog. Reflectivity drops, moisture lingers, and the foil starts looking dull and streaked. We inspect and either clean or replace the affected sections.
- Radiant barrier installed against the roof deck without baffles. This is the most common failure we see anywhere in San Francisco. Foil stapled directly to rafters traps moisture, rusts fasteners, and does nothing useful. We reinstall with a one-inch ventilated air gap and proper baffles so the barrier actually reflects heat instead of cooking the roof assembly.
Reflectix Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s what most insulation pages won’t tell you about San Francisco: the city’s persistent marine moisture changes how Reflectix has to go in. Out in the Outer Sunset, where fog hangs around well past noon, a solid radiant barrier installed tight against the roof deck will condense on the foil’s cool surface and drip water into whatever’s below. Insulation contractors who work dry inland heat don’t always plan for that. We do. Every Reflectix install we run in fog-adjacent San Francisco neighborhoods includes a ventilated air gap, vapor-open detailing, and a check for what’s already wet before anything new gets stapled up. The same product in Livermore or Walnut Creek can sometimes be installed tight without issue. In the Outer Sunset or the Richmond, that approach fails within a season or two.
That’s the information gain here: Reflectix in San Francisco is a moisture-management problem first and a heat-reflection problem second. If you’re getting quotes and one contractor never mentions fog, venting, or vapor drive, that’s your sign to keep looking.
Reflectix Models & Products We Service in San Francisco
We work with the full Reflectix line that matters for San Francisco homes. That includes the Double Reflective Insulation Roll (the bubble pack most people picture), the Double Reflective Foil Insulation (single bubble, good for tight cavities), the Radiant Barrier in both perforated and non-perforated versions, and the Reflective Duct Insulation Wrap we use around duct runs in basements and crawl spaces. We stock genuine Reflectix rolls and factory tapes, not aftermarket foils. Aftermarket product uses thinner Mylar and fails faster in San Francisco’s salt-laden air, so we don’t install it. When a Reflectix job is water-damaged or delaminated, we replace only the affected runs unless the foil is acting as a vapor retarder in a wet crawl space. In that case, full replacement is the honest recommendation.
Reflectix Service Pricing in San Francisco
Expect to pay $2.50 to $6.00 per square foot installed for Reflectix work in San Francisco. A small crawl space job in the Outer Sunset might land around $900 to $1,400 total. A full attic radiant barrier with baffles and air-sealing in a Noe Valley Edwardian typically runs $2,000 to $4,200. Duct wrap in a Sunset stucco home usually falls between $600 and $1,200. What drives the cost: access (Victorians have tight attic hatches), whether old wiring needs inspection first, how much damaged material has to come out, and how much air-sealing we do alongside the foil. Every estimate is written, itemized, and delivered to you before any work begins. No post-job surprises. Call (864) 428-1615 and we’ll walk you through what your specific San Francisco home needs.

FAQs – Reflectix Insulation in San Francisco
Can Reflectix be used in a San Francisco Victorian without violating historic façade rules? Yes, because Reflectix goes inside wall cavities, attics, and crawl spaces, not on the exterior. San Francisco Planning’s Article 10 governs exterior alterations, and interior insulation work like Reflectix doesn’t trigger façade review. That’s why it’s a practical choice for Victorians and Edwardians where exterior insulation would never be approved. Call (864) 428-1615 and we’ll confirm your specific district’s requirements.
Does Reflectix work in a damp Outer Sunset crawlspace? Only when it’s installed with a ventilated air gap and the crawlspace itself has its moisture handled first. Reflective foil against a wet dirt floor just traps dampness and rusts. We check the vapor drive, address any standing moisture, then hang Reflectix so air can move behind it. Get an inspection before you buy product. Estimates are free at (864) 428-1615.
Why does Reflectix sometimes fail in San Francisco attics? The usual culprits are fog-belt moisture condensing on the foil’s cool surface, improper installation with no air gap, and perforations that clog with dust. In Bernal Heights, we opened an attic above a 1920s Edwardian and found Reflectix pressed flat against the roof deck, trapping fog-belt moisture and rusting the staples. We pulled the damaged runs, checked for knob-and-tube wiring, and reinstalled perforated Reflectix with a one-inch ventilated air gap and new baffles. The upstairs felt less drafty within two weeks.
Is Reflectix a replacement for traditional attic insulation in San Francisco? Not by itself. Reflectix is a radiant barrier, not a primary insulator. In San Francisco’s mild, damp climate, air sealing and radiant barrier work together, and our three core services, attic insulation, our Spray Foam Insulation in San Francisco, and blown-in insulation, cover the full picture. Reflectix handles radiant heat and acts as a vapor-open surface. You still need proper air sealing at the attic floor. Call (864) 428-1615 for a straight answer on what your attic actually needs.
Do you need a pre-inspection before installing Reflectix near old wiring in Noe Valley? Yes. In Noe Valley and Bernal Heights, we frequently find knob-and-tube wiring or abandoned gas lines inside exterior walls. Installing any foil without checking what’s behind the wall risks code violations and fire hazards. We inspect before anything goes in. It’s non-negotiable on our end.
