What makes us different here isn’t a slogan. Burlingame’s housing stock from Easton Addition to Burlingame Park runs older, tighter, and wetter than most people expect. Marine-layer moisture, post-and-beam framing, and decades-old fiberglass batts interact with spray foam in ways you only learn by working these blocks for years. We have. Our Spray Foam Insulation team has cut its teeth on Burlingame basements, attics, and rim joists from the Caltrain corridor to the hills above El Camino Real.
Why Laurel Attic Insulation Is Burlingame’s Preferred Spray Foam Insulation Company
We’ve worked enough Burlingame homes to know exactly what’s behind your lath-and-plaster walls before we cut the first access panel. Homeowners on Oak Grove Avenue, in Ray Park, and around Washington Elementary reach out because they’ve heard from neighbors that we show up when we say we will. That reputation is built on the Relay Visibility Guarantee: live arrival tracking, before-and-after photos, and a written price before work starts. Every job. No exceptions.
Our founder, Chase Whitaker, built Laurel Attic Insulation in 2003 as part of the Relay Home Co. family with one rule: write everything down. Your price, your warranty, your job photos. If you’re in Burlingame and you’ve been burned by a contractor who ghosted you after a deposit, you’ll notice the difference in the first phone call. A live person answers, 24 hours a day, not a voicemail queue.
Spray Foam Attic Insulation in Burlingame
Spray Foam Attic Insulation in Burlingame typically involves removing old fiberglass batts or blown-in material, air-sealing top plates and penetrations, then applying open-cell or closed-cell foam to the attic envelope. Burlingame homeowners with post-and-beam ceilings in Easton Addition often have unvented roof assemblies where this approach is the only thing that stops conditioned air from leaking straight through the ceiling. In those homes, the difference after install is immediate: quieter rooms, fewer drafts, and a furnace that runs noticeably less.
Open-Cell for Burlingame’s Marine Climate
Open-cell spray foam expands to fill odd-shaped bays and post-and-beam pockets better than any batt. Its lower density also lets moisture migrate rather than trapping it against roof sheathing, which matters in Burlingame’s fog-heavy microclimate. We specify open-cell for most attic roof decks here because it accommodates the condensation cycles that come with marine-layer humidity.
Closed-Cell Where Space Is Tight
Closed-cell foam cures rigid and adds structural strength, which helps in Burlingame’s older homes where roof framing has settled over decades. It costs more per board foot but delivers roughly double the R-value per inch. For small attic cavities or rim joists in Burlingame Park bungalows, closed-cell often wins on both insulation value and moisture resistance.
Spray Foam Wall Insulation in Burlingame
Spray Foam Wall Insulation in Burlingame means opening wall cavities or injecting foam into existing enclosures to stop air movement and thermal bridging. Burlingame homes built before 1970 often have either zero wall insulation or settled fiberglass that’s doing almost nothing. We see it on Sanchez Avenue, in Lyon Hoag, and throughout the flats: walls that feel cold to the touch in January because the original cavity insulation has slumped to the bottom third of the stud bay.
Injection Foam for Finished Walls
Injection foam goes in through small holes drilled in drywall or plaster, expands in the cavity, and cures without tearing out your finished surfaces. It’s a smart fit for Burlingame homes where original built-ins or period trim make full wall demolition impractical.
New Builds and Remodels
If you’re adding a room off the back of an Easton Addition home or finishing a garage on Bellevue Avenue, open-cell spray foam in the new wall cavities gives you a continuous air barrier from day one. We coordinate with your general contractor on timing so our crew isn’t holding up framing or drywall.
Trusted Brands We Service in Burlingame
We’re not married to one manufacturer, and that matters when Burlingame’s building stock ranges from 1920s Tudors to 2010s infill. We specify Owens Corning for high-R-value attic applications, Icynene for its open-cell moisture behavior in fog-zone roof assemblies, and Rockwool where fire ratings or sound attenuation are part of the conversation. Because we stock foam from multiple brands, we can match product to your Burlingame home’s actual needs instead of pushing whatever’s already on the truck. That’s the only way to spec a Burlingame Park attic correctly.
Common Spray Foam Insulation Problems We See in Burlingame Homes
– Compressed fiberglass in post-and-beam attics. Burlingame’s Easton Addition and Burlingame Park homes often have HVAC units or duct runs sitting directly on top of old batts. The compression destroys the R-value, leaving gaps that marine-layer air pushes right through. Removing and replacing with spray foam fixes the air seal permanently.
– Rodent and bird damage near the eaves. Burlingame’s mature street trees create a highway for squirrels and rats to access attics. Contaminated batts near eave vents are the most common reason we do insulation removal in this city before spraying foam. Skip the pest exclusion and the new foam’s air seal fails within a season.
– Condensation against unvented roof sheathing. Homes near the Caltrain corridor and Burlingame Avenue frequently have roof assemblies with no ridge vent and no soffit ventilation. Spraying closed-cell foam directly against sheathing in those conditions can trap moisture if details aren’t right. We inspect and spec open-cell or add ventilation before we spray.
– Knob-and-tube wiring entombed in insulation. Burlingame homes from the 1920s and 1930s still have knob-and-tube circuits in attic and wall cavities. Spraying foam directly over live, unprotected knob-and-tube wiring is unsafe, period. We verify the electrical before any foam touches a stud bay.

FAQs About Spray Foam Insulation in Burlingame
Can you do same-day spray foam insulation in Burlingame if my attic is losing heat?
Yes, we run same-day emergency calls to Burlingame for attics with active heat loss. We recently responded to a same-day call in the Easton Addition where a homeowner had attic fiberglass batts that had been compressed and rodent-contaminated near the eaves. After an inspection showed open cavities above the post-and-beam ceiling, our crew removed the old batts, air-sealed the top plates and can lights, and installed Icynene spray foam in the attic envelope. The homeowner noticed a quieter, more consistent indoor temperature by that evening, and we scheduled a follow-up moisture check for the following week. Call (361) 315-4177 before noon and we can usually get a crew out the same day.
My Burlingame home has old fiberglass batts – should I repair them or replace with spray foam?
Replace them. Repairing compressed or contaminated fiberglass almost never makes sense in Burlingame’s older homes. The post-and-beam assemblies in Easton Addition and Burlingame Park get compressed by ducts and HVAC equipment, leaving gaps that no amount of fluffing will fix. Spray foam creates a continuous air seal that batts cannot match, and in Burlingame’s marine-layer climate, that air seal is what keeps the fog-dampair from pulling heat out of your ceilings all spring. The cost difference between patching batts and a proper spray foam job is usually recovered in the first two winters.
Does Burlingame’s marine layer affect which spray foam you use?
Yes, it does. Burlingame sits in a fog belt where overnight humidity regularly hits 85 to 95 percent from June through September. That means roof sheathing in unvented assemblies runs with condensation for half the year. We lean toward open-cell foam for attic roof decks here because its vapor permeability lets moisture move through and dry rather than getting trapped against the wood. Closed-cell gets used selectively, usually in rim joists or walls where vapor drive is less of a concern.
How do you handle rodent damage before spraying foam in a Burlingame attic?
We remove the contaminated insulation first, then inspect for entry points and active nests. Burlingame’s tree canopy, especially around the older sections near Hillsborough, means roof rats and squirrels are constant attic pests. We won’t spray foam over droppings or damaged wiring. Once the attic is cleared, we air-seal the entry points and then apply the foam. We work with a Burlingame pest exclusion partner, and we’ll tell you right away if you need to coordinate that step.
Do you service older Burlingame homes with knob-and-tube wiring or unvented roof assemblies?
We do, and we handle both carefully. For knob-and-tube, we follow standard safe-install guidance: we won’t bury live knob-and-tube circuits under foam. We’ll recommend an electrician’s sign-off or a wiring upgrade before spraying those cavities. For unvented roof assemblies, which are common in Burlingame’s pre-1960 stock, we apply open-cell foam with proper gap details to allow drying. Burlingame’s older homes are the bulk of our work, and we’d rather walk you through the right sequence than spray something we’ll have to fix later.
