Bay Area Siding Company installs replacement and new-construction windows for San Bruno homeowners, from the mid-century tracts on the hillsides to the older homes near downtown. We're a Larkspur-based siding and window contractor working the Peninsula, and we run the full job: measuring, glass and frame selection, permitting and the Title 24 energy paperwork, removal, flashing and air-sealing, and a final walkthrough. In a city that sits close to SFO, one decision tends to matter more here than almost anywhere else — how much aircraft noise the glass keeps out.

Signs it's time to replace

Much of San Bruno's single-family stock dates to the postwar decades, and a lot of it still has the original single-pane wood windows. They tend to tell on themselves:

• Drafts you can feel at the sash even when it's shut — the gap wind finds every gap.
• Fog or moisture trapped between the panes on a dual-pane unit, meaning a failed seal that can't be repaired.
• Sashes that stick, drop, or won't latch from swollen wood, paint, or worn balances.
• Outside noise that seems to walk right in — single-pane glass does almost nothing against jet noise.
• Rot or water staining at the sill, stool, or surround.

Two or more of these usually means replacement is the smarter long-term move than another round of repair.

What to look for in a San Bruno window

Three choices carry the most weight here:

• Sound control. This is the San Bruno difference. Because much of the city sits under SFO arrival and departure paths, glass makes a real quality-of-life difference. Window noise reduction is measured by Sound Transmission Class (STC), and every jump of about 10 points roughly halves perceived loudness. Single-pane windows sit low on that scale; a well-built dual-pane unit does much better, and packages using laminated glass or two panes of differing thickness climb higher still. If a quiet bedroom is the goal, tell us early so we can spec the glass to it.
• Energy performance. Look for dual-pane insulated glass with a Low-E coating. California's Title 24 energy code caps U-factor and SHGC for replacement windows, and the numbers shift by climate zone and code cycle — so rather than quote fixed figures, we confirm the values in effect at permit time and spec to them.
• Frame material and fit. Vinyl, fiberglass, aluminum-clad wood, and aluminum each balance cost, thermal performance, and looks differently. On San Bruno's ranch and mid-century homes, a clean profile that respects the original opening usually reads best. We do both retrofit (insert) installs, which keep the existing frame, and new-construction installs, which go back to the framing so flashing can be fully renewed — the right call where there's rot or past water intrusion.

What to expect: our process

1. Consultation — we look at the existing windows, the openings, and what you want out of the change (comfort, noise, efficiency).
2. Measure — exact field measurements for every opening.
3. Product and energy selection — glass package, frame, and finish chosen to meet current Title 24, with sound control dialed in where it matters.
4. Permit — San Bruno requires a building permit for window replacement, and the Title 24 energy documentation goes in with it.
5. Removal and prep — old units out, openings checked for rot and damage.
6. Install, flashing, and air-seal — set level and plumb, then flashed and sealed against wind-driven water and air.
7. Finish and walkthrough — trim, caulk, an operation check, and cleanup with you.

San Bruno-specific things to know

Permits and energy paperwork. Window replacement in San Bruno goes through the city's Community & Economic Development Department, Building Division, and a building permit is required. Because the city treats window replacement as an alteration under the Energy Code, Title 24 fenestration compliance documentation is part of the submittal. We prepare and handle it.

You're near SFO — and the county knows it. San Bruno lies within the San Francisco International Airport influence area under the airport's Comprehensive Land Use Plan, and the San Mateo County Airport Land Use Commission reviews development for noise and safety compatibility. For a homeowner, the practical takeaway is simpler: aircraft noise is a real, everyday factor here, and the window you choose is the single biggest lever you have over how much of it reaches your living space. Sound-rated glass is worth the conversation.

The gap climate. San Bruno catches the marine air and wind that pour through the coastal gap, so wind-driven rain and air infiltration are the enemies at the window opening. Getting the flashing and air-seal right is as important as the unit itself.

Fire-zone edge parcels. Most of San Bruno is not in a mapped fire zone, but the city has adopted the state's Fire Hazard Severity Zone map, and hillside and open-space-edge parcels can be designated. Where an opening in a designated-zone home is altered, Chapter 7A generally calls for multi-pane glazing with at least one tempered pane, among other requirements. It depends on your parcel and whether the work is a repair or an alteration, so we confirm it during scoping.

What affects the cost

Every job is different, so we don't quote online. The drivers are the number and size of openings, frame material and brand, retrofit versus new-construction, the glass package (a high-STC sound-control or laminated build costs more than base dual-pane), whether a fire-zone parcel requires tempered/multi-pane glazing, the condition of the existing framing (rot repair adds scope), and access on upper stories or hillside lots. We price it after measuring.

Frequently asked questions

Can new windows actually cut the airplane noise in San Bruno? Yes, meaningfully. Noise reduction is rated by STC, and moving from single-pane to a well-built dual-pane — or a laminated/acoustic package — can roughly halve or more the perceived loudness inside. It won't erase every jet, but it changes how a room feels. We spec the glass to your exposure.

Do I need a permit to replace windows in San Bruno? Yes. The city requires a building permit for window replacement, and Title 24 energy compliance documentation is part of the submittal. We handle both.

Which frame keeps the look of my mid-century San Bruno home? Several can. Vinyl, aluminum-clad wood, and aluminum all offer clean profiles that suit the era's openings; we match the profile to the home.

Retrofit or new-construction install — which is right? Retrofit is less invasive and keeps the existing frame; new-construction goes back to the framing and is the better choice where there's rot or water damage and you want the flashing fully renewed. We assess and recommend.
