A California craftsman-style home at golden hour in a Central California neighborhood — Burlingame, California service area

Insulation Installation in Burlingame, CA

101 Exterminators handles insulation installation in Burlingame after a removal or in an under-insulated attic, working to California Title 24 standards under SPCB Lic. #9119 since 2005. Burlingame's median house was built in 1957 and its oldest neighborhoods predate 1940, so most attics here were framed long before any energy code existed. We confirm the attic is rodent-free and air-sealed first, then insulate.

Burlingame Attics Were Framed Before Any Energy Code Existed

Most Burlingame houses were built to no insulation standard at all. About 29 percent of the stock predates 1940 and the median build year is 1957 — decades ahead of California Title 24 setting minimum R-values — so what is up there is whatever a previous owner added and however it has settled since. A mild marine climate hides that under-performance well. Highs run 70 to 73°F and winter lows sit at 44 to 46°F, so nothing forces the issue the way inland heat does. The house is just cold in the morning and expensive in a quiet way.

Insulation and pest work belong together here for a specific reason. A vented Burlingame attic that leaks air at recessed lights and top plates pushes warm, humid interior air into the roof assembly, and warm damp fill is what makes an attic attractive to roof rats and the insects that follow them. Borate-treated cellulose adds inherent pest resistance to the same material doing the thermal work, and the air sealing that has to happen first closes the same small gaps a mouse would use.

The raised-foundation houses need the other half of the assembly. Under-floor batt in the joist bays of a pre-1940 Easton Addition or Burlingame Park house makes a real difference in a city where the ground stays damp and the floor sits over open air — but only if the vapor barrier is in place and the sub-area is dry first. Wet fiberglass insulates nothing and holds moisture against the joists. The order of operations decides whether the work is worth doing at all.

How We Work in Burlingame

We measure what is there before adding anything. In a Burlingame attic that means depth and condition of the existing material, moisture staining from old roof leaks, and whether the rodent entries along rafter tails and vents are genuinely closed. We air seal at recessed lights, plumbing penetrations, top plates and the attic hatch, then blow cellulose or fiberglass to the target R-value, or install batt in crawl space joist bays. We work to Title 24 and can provide documentation when a permit requires it.

Burlingame Climate

Burlingame has a mild Peninsula climate — warmer than Daly City, partially sheltered from marine fog by the San Francisco Peninsula geography. Summer temperatures regularly reach the mid-70s°F, supporting drywood termite swarm activity from May through October. Annual rainfall of 19–21 inches.

Housing Stock

Burlingame Park, the Easton Addition, and the residential neighborhoods around downtown have significant pre-1940 Craftsman and Colonial Revival housing stock with original wood framing. These properties have the highest drywood termite risk in the city. Post-WWII development in Burlingame Hills and the Alcazar area represents newer construction with lower but non-zero termite risk. Broadway corridor commercial buildings include older structures with termite histories.

Why Local Expertise Matters

Burlingame's pre-1940 Craftsman and Colonial Revival homes require the same specialist approach as Oakland and Berkeley's historic neighborhoods. We understand the termite vulnerability of original old-growth framing, the treatment options appropriate for historic structures, and the WDO reporting standards expected in Burlingame's high-value real estate transactions.

Our Insulation Install Process in Burlingame

Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Burlingame.

01

Existing Conditions Assessment

We measure current insulation depth, note any areas requiring air sealing before installation, and confirm that the attic is rodent-free before new insulation goes in.

02

Air Sealing (As Needed)

Gaps around recessed lights, plumbing penetrations, HVAC ductwork, and top plates are sealed before insulation is blown in to maximize thermal performance.

03

Insulation Installation

Machine-blown cellulose or fiberglass is distributed to uniform depth and density across the attic floor or specified area. Depth gauges are placed and photographed for documentation.

04

R-Value Confirmation

Installed depth is documented and final R-value confirmed. For permit applications, we provide the necessary documentation of materials and installation specs.

Insulation Install You Can Count On in Burlingame

Title 24 Compliance

We install to California energy standards with documentation for permit and utility rebate purposes.

Pest-Resistant Options

Borate-treated cellulose provides both thermal performance and inherent pest resistance — termites and cockroaches avoid borate-treated materials.

Insulation Installation FAQs for Burlingame

What R-value should a Burlingame attic have?

California Title 24 sets the minimum for the climate zone, and most attic retrofits on the Peninsula land in the R-38 to R-60 range depending on the assembly. Coverage matters as much as the number: fill that stops short at the eaves, gets compressed under stored boxes, or sits over unsealed penetrations does not deliver what the label promises. We measure existing depth and give you the practical target for your attic instead of a generic figure.

Is insulation worth doing in Burlingame when the weather here is this mild?

Yes, though the payoff shows up as comfort and even temperature more than as a dramatic change in heating. Burlingame runs 44 to 46°F on winter nights and 70 to 73°F on summer afternoons, so an under-insulated house here does not fail spectacularly — it runs cold in the morning, holds heat unevenly and loses whatever the furnace makes straight through the ceiling. On raised-foundation houses the cold floor is usually the bigger complaint than the attic.

Can insulation itself be made rodent- or insect-resistant in a Burlingame attic?

Borate-treated cellulose carries inherent resistance to insects, which is worth having in a city with this much termite pressure, but no insulation product keeps rodents out by itself. Rats and mice tunnel through any loose fill. What stops them is exclusion at the rafter tails, vents and roof-to-wall transitions before the material goes in. We treat those as one job — seal the envelope, then insulate — because the other order wastes the insulation.
