Fast, Reliable Blown In Insulation Across Burlingame
Most blown-in insulation jobs in Burlingame run between $1,800 and $4,200 for a typical 1,200 – 1,800 square foot attic, depending on current depth, access, and whether we’re removing old material first. That’s the number we quote before a single tool comes off the truck, and it holds. If your attic feels drafty in the winter, hot in the summer, or you’ve noticed damp smells near the roofline, call Alden Attic Insulation at (254) 272-5876. We serve every Burlingame neighborhood, from the flats near Burlingame Avenue up to the hills west of El Camino Real, and we answer the phone with a live person 24/7.

Why Alden Attic Insulation Is Burlingame’s Preferred Blown In Insulation Company
Burlingame homeowners tend to ask the same three questions: Will you show up when you say you will? Will the price hold? Will you stand behind the work if something fails? Our answers are yes, yes, and yes, in writing, for 365 days. That’s the 365-Day Done Right Promise, and it’s not a sales line. It’s the operating standard that comes with being part of the Garrison Partners family, established 2002.
Every Alden technician who walks into a Burlingame home is background-checked and in uniform. You’ll know exactly who is in your attic, and they’ll arrive inside the scheduled window, not a vague four-hour range. We don’t subcontract the work out. The crew that shows up is the crew that answers to Bryce Holloway, and Bryce answers to you.
Local knowledge matters here more than most people realize. Burlingame’s housing stock runs from 1920s bungalows in Burlingame Park to 1960s ranchers in the Easton Addition, and each era has its own attic quirks. We’ve worked in enough of them to know what we’re looking at before we climb the ladder.
Blown In Insulation Contractors in Burlingame
Blown In Insulation Contractors in Burlingame handle the full job: removing old or failed insulation where needed, air sealing the attic floor, installing or repairing baffles from brands like Owens Corning or CertainTeed, and blowing new material to a uniform depth across every joist bay. In Burlingame specifically, the job often starts with a moisture assessment, because the marine air off San Francisco Bay pulls condensation into attics that aren’t ventilated properly. We check that first, before adding any new material.
What the job covers
A standard blown-in insulation job in Burlingame takes one day for most homes. The crew removes any damp or matted material, checks the soffit and ridge venting, air seals around can lights and plumbing penetrations, then blows cellulose or fiberglass to the R-value your attic needs. That’s usually R-38 to R-49 in Burlingame’s climate zone, which keeps the upstairs livable year-round without overspending on material you don’t need.
When Burlingame homeowners call us
Most calls start the same way: a bedroom that won’t hold heat in January, or an upstairs hallway that bakes all afternoon in July. Sometimes it’s a pest issue, sometimes it’s a remodeling project where the attic got opened up and the old insulation looked worse than expected. Whatever the trigger, we can usually get a crew to your Burlingame home within one to two business days, and same-day calls are common.
Cellulose Insulation in Burlingame
Cellulose Insulation in Burlingame is one of the most effective materials for older homes, but only when the attic is dry and ventilated. We install GreenFiber cellulose, a brand you can research yourself. It’s made from recycled paper treated with borate for fire and pest resistance, and when blown to the correct depth, it settles into every corner of the attic in a way batts never will. In a Burlingame attic with good airflow, cellulose holds its R-value for decades.
Why cellulose works for older bungalows
Burlingame’s 1920s and 1930s bungalows have irregular joist spacing, odd angles, and settled framing that makes batt insulation a poor fit. Cellulose fills those gaps completely. We blow it to a consistent depth across the entire attic floor, including around cross-bracing and electrical runs that would leave gaps with any other material.
Moisture and cellulose: what we check first
The honest caveat with cellulose in Burlingame: if your attic traps moisture, blown-in material will mat down and lose its R-value within a few seasons. The marine layer is real, and homes in the flats near Burlingame Park and the Easton Addition get condensation along the roof deck more often than hillside homes. Before we blow in a single bag, we check the venting. If soffit or ridge vents are missing or blocked, we address that first. Otherwise the new insulation is just absorbing water and failing quietly.
Trusted Brands We Service in Burlingame
We install and remove insulation using products from brands you can look up independently: Johns Manville, Knauf, Rockwool, and CertainTeed, along with GreenFiber cellulose and Owens Corning accessories. We stock the common sizes and accessory parts for Burlingame jobs, so we don’t have to stop mid-install and run to a supply house in San Mateo. If your attic needs baffles, ridge venting, or vapor management material, we’ve got it on the truck. That means a one-day install stays a one-day install.
Common Blown In Insulation Problems We See in Burlingame Homes
- Cellulose blown over old, damp batts. In the Bay-adjacent flats, particularly around Burlingame Park and the Easton Addition, we regularly find cellulose that was blown directly on top of wet fiberglass. The moisture wicks up, the cellulose mats down, and the R-value drops to nearly nothing within a few seasons. The fix is removal first, then ventilation, then new material.
- Condensation from blocked or missing attic venting. Burlingame’s marine layer pushes moisture into attics that lack proper soffit and ridge ventilation. That condensation compresses blown-in insulation against the roof deck and stains the sheathing. We address the airflow problem before we add insulation, because no material survives a perpetually damp attic.
- Knob-and-tube wiring and recessed can lights buried in insulation. Older Burlingame bungalows often still have knob-and-tube circuits or older recessed lights that get insulation blown directly against them. That’s a fire hazard and a code violation. On every job we inspect for these before we start blowing, and we install proper barriers or recommend the necessary electrical work first.
- Settled batts that look fine from the access hatch but are doing nothing. Fiberglass batts in a 100-year-old Burlingame attic can look presentable from the hatch while being completely compressed, dusty, and ineffective across the actual ceiling. We check the depth and condition in every corner of the attic, not just at the opening.

FAQs About Blown In Insulation in Burlingame
Will blown-in cellulose actually work in a damp Burlingame attic near the Bay?
Yes, but only if the attic ventilation is addressed first. Cellulose holds its R-value for decades in a dry, properly vented Burlingame attic. In a damp one, it mats down and fails within a few seasons. We inspect the soffit and ridge venting on every job and don’t blow new material into a moisture trap. Call (254) 272-5876 and we’ll tell you what your attic actually needs.
Can you get to a Burlingame blown-in insulation job the same day I call?
Yes, same-day service is common for Burlingame, especially for removal jobs where water damage or pest issues have made the attic unsafe. We schedule by exact window, not a half-day range, and the crew arrives in uniform. If it’s urgent, call (254) 272-5876 and a live person will give you a straight answer.
My Burlingame bungalow still has old fiberglass batts – do you remove them before blowing in cellulose?
We remove them if they’re damp, matted, compressed, or contaminated by pests or dust. In a 1920s Burlingame bungalow, old batts are almost always past their useful life, and blowing over them just creates a moisture sandwich. Removal is included in the written quote when we can see it’s needed, and the price doesn’t move after you approve it.
How do you handle knob-and-tube wiring or recessed lights before blowing in insulation in old Burlingame homes?
We inspect for knob-and-tube wiring and older recessed can lights on every Burlingame job before blowing. Insulation cannot be blown directly against active knob-and-tube, and non-IC-rated recessed lights need proper barriers. We flag these issues during the estimate, and if the necessary electrical work is already done, we proceed. If it’s not, we pause and tell you exactly what’s needed. Never guess on this one. Call (254) 272-5876 for a free inspection.
What R-value should I target for a Burlingame attic, and does the marine layer change that?
R-38 to R-49 is the right target for most Burlingame attics. The marine layer doesn’t change the target number, but it changes the preparation. A damp attic loses R-value regardless of what you blow in, so ventilation and vapor management matter as much as depth. We factor both into your written quote, and the guarantee covers the full system for 365 days. Call (254) 272-5876 for the exact number for your attic.
If your Burlingame attic is cold in winter, hot in summer, or smells musty after a wet spell, we’ll inspect it and give you a written price. No pressure, no price changes, no surprises. Call Alden Attic Insulation at (254) 272-5876.
