Why Alden Insulation San Francisco Is Burlingame’s Preferred Attic Insulation Company
Burlingame homeowners have a specific frustration: contractors who no-show, revise the quote at the door, or leave pink fiberglass dust across the upstairs hallway. Alden runs differently because we’re held to The Garrison Standard. That’s not a slogan. It means a written price before work starts, a written 365-day guarantee on every job, and a crew that cleans up after itself. We’ve been part of the Garrison Partners family since 2002, and the same discipline applies whether we’re topping up a 1960s ranch in Ray Park or doing a full insulation removal in a 1920s stucco home off Chula Vista Avenue.
Our Attic Insulation team knows Burlingame’s housing stock the way a local knows which streets flood in January. Pre-1980s homes here carry specific problems: compressed R-11 batts, rodent-damaged material, blocked soffit vents, and attic floors with no air sealing whatsoever. We don’t send a generalist. We send technicians who have opened dozens of Burlingame attics and know what they’ll find before the ladder goes up.
Insulation Contractors in Burlingame
Insulation Contractors in Burlingame do the work most homeowners will never see: crawling across joists in a dark attic, pulling out old batts, sealing air leaks, and blowing in material to a specified R-value. A proper job in Burlingame costs $1,450 to $3,200 for most homes. The variables are square footage, access difficulty, and whether you need removal before the new material goes in. We don’t quote over the phone. We measure, inspect, then hand you a written number.
Full Removal and Replacement
When insulation is rodent-damaged, water-stained, or compressed to half its original R-value, topping up won’t fix it. We remove the old material, sanitize the attic floor, air-seal penetrations, and install fresh blown-in or batt insulation. This is the heavy-duty version of the job, and it’s the right call for many pre-1980 Burlingame homes.
Top-Up Over Existing Insulation
If your existing insulation is dry, uncontaminated, and just undersized, a top-up brings you from R-11 or R-19 up to R-38 or R-49. That’s the most cost-effective path for 1940s and 50s ranch homes in Burlingame where the original batts are still in decent shape.
Attic Ventilation in Burlingame
Attic Ventilation in Burlingame isn’t optional, not with the marine layer rolling in most summer mornings and cool, damp air settling against roof sheathing. Without proper airflow, humidity gets trapped in the attic and condenses on the underside of the roof deck. Insulation loses effectiveness when it’s damp. Mold follows. A ventilation upgrade with baffles and a correctly sized fan can run $475 to $1,100, depending on attic size and whether we’re adding soffit vents, a ridge vent, or a powered unit.
Baffles and Soffit Intake Prep
Before any blown-in insulation goes in, we install baffles at the soffit line so the material doesn’t block airflow. In Burlingame’s pre-1980s homes, soffits are often clogged with old paint, bird nests, or decades of grime. We clear them so the ventilation system actually works.
Powered and Solar Attic Fans
For attics that bake in the afternoon sun east of El Camino Real, a solar-powered attic fan pulls hot air out without adding to the electric bill. It’s a clean solution for Burlingame’s older homes where running new wiring would be invasive. Install typically runs $520 to $950 with the unit included.
Trusted Brands We Service in Burlingame
We install and remove insulation using products from eight industry-respected brands, so homeowners can research exactly what’s going into their attic before they sign. For blown-in work on Burlingame’s older homes, we often use Owens Corning fiberglass and GreenFiber cellulose. For spray foam on specific projects like rim joist sealing or cathedral ceilings, we work with Icynene and Demilec. We stock these materials locally for fast turnaround on Burlingame jobs, which means we’re not waiting on a shipment when your attic is already opened up and the clock is running.
Common Attic Insulation Problems We See in Burlingame Homes
- Compressed R-11 batts in 1940s-60s ranch homes. What started as R-11 batt insulation in a Burlingame ranch settles and compresses under decades of dust and foot traffic. We regularly measure it at R-8 or lower, which leaves cold spots across the attic floor that invite condensation in the fog season.
- Rodent-damaged insulation in Easton Addition homes. The 1920s stucco houses built with balloon framing have open wall cavities that doubled as rodent highways for a century. When we open these attics, we often find droppings, nesting material, and shredded insulation that has to be removed and replaced, not topped up.
- Unsealed attic floors that pull moist air from the crawlspace. Balloon-framed homes in Burlingame channel damp, salty air from the crawlspace straight up through wall cavities into the attic. Insulation laid over those open cavities loses its effectiveness, and rust on metal fasteners is the telltale sign.
- Inadequate ventilation that traps marine-layer humidity. Even homes with adequate R-value struggle with mold on the underside of roof sheathing if the attic can’t breathe. Burlingame’s summer fog delivers moisture every night, and a sealed-up attic holds it like a sponge.

FAQs About Attic Insulation in Burlingame
Yes, in most cases. R-11 batts from that era have typically compressed to R-8 or lower, and they’re often holding dust, rodent droppings, or moisture. Adding new blown-in material over degraded batts won’t give you the R-value you’re paying for, and it traps contaminants in place. We’ll inspect before we quote and tell you honestly whether removal is necessary. Call (559) 245-9792 to schedule an inspection.
No, attic insulation alone won’t stop the drafts in a balloon-framed Easton Addition home, but it makes a measurable difference. The open wall cavities channel cold, damp air from the crawlspace into the attic, so without wall work you’ll still feel air movement near baseboards and floors. Our crew can air-seal the attic floor, which cuts a significant portion of that stack effect, and then install dense-pack cellulose into the wall cavities if you want to tackle the full problem. The first step is an attic inspection to see exactly what you’re dealing with.
It’s the primary defense. Burlingame’s summer fog delivers moisture into attics every night, and without soffit-to-ridge airflow, that moisture condenses on the roof sheathing and soaks into the insulation. Proper ventilation with baffles and adequate exhaust drops the relative humidity in the attic, which keeps the insulation dry and performing at its rated R-value. We inspect ventilation as part of every insulation job, because in Burlingame the two can’t be separated.
Modern blown-in fiberglass and cellulose are installed at a density engineered to resist settling, and in Burlingame’s climate they’ll hold their R-value for decades. The settling you see in older Burlingame attics came from 1950s-era installation methods and low initial R-values, not from the material itself. We install to manufacturer specs and the 365-Day Done Right Promise covers the work for a full year. If it fails in that time, we come back at no charge.
Yes, and we do it regularly. We remove the contaminated material, sanitize the attic floor, seal entry points where we can, and then install new insulation to code. This is a full-day job on most Burlingame homes and it’s the only correct way to deal with rodent-damaged material. Call (559) 245-9792 for a free estimate on the full removal and replacement scope.
If your attic has been ignored for thirty years, it’s not a weekend project. It’s a one-trip job for a crew that knows Burlingame’s houses and stands behind the work in writing.
