The fog that rolls over the eastern hills every summer isn’t just a weather pattern. It’s the reason your 1930s Spanish Revival feels colder inside than the thermometer says it should. Drafty walls, settling insulation, and no vapor barrier mean moisture gets in and stays. We fix that by treating insulation as a moisture-management job first and a comfort upgrade second. That’s the only way to do it right in a coastal city like Burlingame.

Why Alden Insulation San Francisco Is Burlingame’s Preferred Blown In Insulation Company

Burlingame homeowners have a specific complaint we hear on nearly every first call: the house feels damp and drafty in rooms facing the Bay, while the walls upstairs stay cold even when the heat runs full blast. That’s not a heating problem. It’s an insulation failure, and it’s usually tied to how the house was built. Pre-war balloon framing, stucco exteriors with no drainage plane, attic hatches that were never sealed. We’ve mapped enough of these failures across Burlingame’s housing stock that we can tell you what you’re dealing with before we cut the first access hole.

Alden Insulation San Francisco operates as part of the Garrison Partners family, established in 2002. Every crew that serves Burlingame works under The Garrison Standard: written prices, written guarantees, background-checked uniformed technicians, and a live person answering the phone 24/7. Bryce Holloway leads our operation, and he’s the one who signs off on every written guarantee we issue in Burlingame. Not a form letter. A real guarantee tied to your address and valid for 365 days.

We show up inside the window we promise, not a half-day range. Our technicians wear uniforms with their name on the shirt. And if the line item on the invoice doesn’t match the estimate you approved, you don’t pay the difference. That’s the discipline Burlingame homeowners deserve after years of contractors who couldn’t be bothered.

Cellulose Insulation in Burlingame

Cellulose insulation in Burlingame is dense-packed into wall cavities and blown loose into attics, and it’s the right choice for about 70% of the pre-1980 homes we service here. The material is GreenFiber or Demilec cellulose, ground from recycled paper and treated with borate for fire and pest resistance. In a Burlingame context, cellulose gives you two things fiberglass can’t: it slows air movement through wall chases, and it manages moisture without trapping it against wood lath.

Dense-Pack for Balloon-Framed Walls

Last March, our crew dense-packed a 1926 Spanish Revival on Chapin Lane in the Easton Addition. The original walls were balloon-framed with zero insulation, and after drilling access holes we hit decades of settled dust and rodent trails, so we first vacuumed the cavities, then blew GreenFiber cellulose to 3.5 pcf, and sealed the holes to stop the damp fog air that had been condensing on the plaster. That’s a textbook Burlingame wall job: open chases from basement to attic, stucco on the outside, and moisture moving through the cavity every summer.

Cost of Cellulose in Burlingame

Dense-pack cellulose wall retrofits in Burlingame run $2.50 to $5.00 per square foot of wall area. Attic loose-fill runs $1.50 to $2.80 per square foot. The spread comes down to access, cavity depth, and whether we need to remove settled insulation first. A 1,500-square-foot Burlingame ranch with R-11 batts doesn’t cost the same as a 1920s Craftsman with no insulation at all.

Blown In Attic Insulation in Burlingame

Blown in attic insulation in Burlingame is one of the highest-return upgrades we do, because so many of the city’s 1940s through 1960s ranch homes came with R-11 batt insulation that has compressed, shifted, or been trampled by decades of trades work. Our crews blow loose-fill fiberglass from Owens Corning or Johns Manville, or GreenFiber cellulose, to R-38 or R-49 depending on your roofline and existing ventilation.

R-Value and Moisture Work Together

R-value only tells half the story in Burlingame. The fog we get from June through September means an attic with good R-value but no air sealing will still let damp ocean air circulate through the insulation blanket. We air-seal the attic floor before we blow. That means caulking top plates, sealing around can lights, and weather-stripping the attic hatch. A sealed attic with R-38 performs better than an unsealed attic with R-60, and it costs less to run.

What to Expect for a Burlingame Attic

A typical Burlingame attic job runs $2,800 to $5,600 for roughly 1,200 to 1,800 square feet, including air sealing and removal of any settled insulation that’s failed. If we need to pull old fiberglass or vacuum rodent debris from the joist bays first, that adds to the quote. We’ll give you the line items up front. The written price you approve is the invoice. No revisions at the door.

Trusted Brands We Service in Burlingame

We install and remove insulation using materials from brands that Burlingame homeowners can research independently before they sign anything. GreenFiber and Demilec cellulose are our most common wall retrofit products, while Owens Corning and Johns Manville supply the fiberglass we blow in attics. We don’t substitute off-brand materials to squeeze margin. If we quote GreenFiber, you get GreenFiber. We keep stock staged for Burlingame service calls, so most jobs don’t wait on a supplier. And because we work across the Bay Area, we can pull from regional inventory when a Burlingame job needs an extra load of material fast. Call (559) 245-9792 and ask us which product fits your house type. We’ll tell you straight.

Common Blown In Insulation Problems We See in Burlingame Homes

• Settling from moisture absorption in unvented stucco walls. Burlingame’s foggy weeks push damp air through stucco, and cellulose that wasn’t dense-packed properly can settle and leave cold bands in the middle of the wall. Condensation on interior plaster is a dead giveaway.
• Rodent-damaged wall cavities in pre-1940 balloon-framed homes. Open chases from basement to attic are highways for rodents. When we blow dense-pack into those cavities without sealing the chases first, cellulose escapes into the attic or crawl space. In Burlingame’s oldest stock, we inspect and seal every chase before we blow.
• Under-insulated 1950s ranch attics with only R-11 batt. The windy hills east of El Camino Real pull heat right out of a minimally insulated attic. Homeowners crank the thermostat, the air inside turns dry, and the heating bill keeps climbing. Blown-in at R-49 changes that.
• Attic hatches and can lights leaking conditioned air. Burlingame homes with original recessed lighting in the top floor ceiling leak warm air straight into the attic. We seal those penetrations before blowing insulation. Skip that step and you’re paying to insulate a roof that’s still breathing.
