No call center, no callback form.
If you’re reading this because a window is fogged, seized, or leaking in a Pacifica home, you’re dealing with something every coastal homeowner here eventually faces. The marine layer never really leaves, and neither does the salt. It gets into the frames, the hardware, the seals. We’ll walk you through what’s actually wrong and what it takes to fix it right.
Why TruePane Windows & Doors Is Pacifica’s Preferred Window Replacement Company
We’ve been working on the coast long enough to know Pacifica is not San Bruno or Millbrae. It’s not even Daly City. Out here on the open Pacific, the wind carries salt spray straight into your window frames. Standard aluminum that survives fine ten blocks inland gets pitted and seized within a few years on Crespi Drive or along Esplanade. Our crews live with this reality. When we quote a window replacement in Pacifica, we’re already thinking about marine-grade hardware, coastal flashing, and what the rough opening is going to look like once we pull the trim.
TruePane was founded in 2008 by Dale Kessler, a second-generation glazier whose family has been setting glass for more than years. Dale’s rule is simple: if the pane is not true, the job is not done. We’re not a franchise playbook. We hire local, train apprentices into journeymen, and plan to be in town thirty years from now. The live person who answers the phone at our San Francisco Bay Area office in the middle of the night is the same kind of person who’ll show up at your door in a uniform, measure every opening twice, and register both manufacturer warranty layers before the truck leaves your driveway.
Every Pacifica job is covered by our Done Right Promise and The Keystone Standard. That means both manufacturer warranty layers registered in writing, durations stated, and workmanship guaranteed for 90 days. No paperwork fights. No arguing. We stand behind it.
Our Window Replacement Services in Pacifica
We don’t treat every window the same, and we don’t treat every Pacifica street the same. A 1958 beach cottage a block off the water needs different material choices than a 1970s tract house up toward the hills. These are the services our Pacifica customers ask for most.
Full Frame Replacement
Most original windows in Pacifica’s 1950s-1970s homes are single-pane aluminum that’s been fighting salt air for fifty or sixty years. A full-frame replacement removes the entire window down to the rough opening, which lets us inspect what’s happening behind the wall. In Pacific Manor, we opened a 1962 cottage on Crespi Drive and found the original sashes so salt-pitted they’d seized in their jambs. Behind the trim, the rough openings were soft from years of wind-driven rain. We fixed the framing, flashed the openings to coastal standards, and installed fusion-welded vinyl double-hungs with low-E glass and argon fill. The old insulated glass units we pulled out tested as total seal failures. After three decades of salt air, every one was dead. Full-frame replacement is the only way to catch those problems before they rot the structure.

Insert Window Replacement
When the existing frames are still square and solid, an insert replacement fits a new window inside the old frame. It’s less invasive and typically 30 to 40 percent cheaper than a full-frame job. In Pacifica, inserts work well on houses set back from the bluffs where the salt load is lighter. But if the old frame has visible corrosion or the sash doesn’t operate smoothly, an insert won’t fix it. We’ll tell you straight which way to go, and we’ll show you both numbers on paper before you decide.

Storm Window Replacement
Pacific storms don’t announce themselves and they don’t aim politely. Along beachfront and bluff-facing streets, wind-driven rain penetrates windows that weren’t bedded and flashed to coastal exposure standards. We replace storm windows with units built for exactly this environment, and we pay close attention to how each one is sealed against the rough opening. Standard weatherstripping degrades in roughly half the expected time within a few blocks of the water, so we specify materials that hold up.

Energy-Efficient Upgrade
Pacifica is one of the foggiest cities in California, and the marine layer sits overhead nearly year-round. Homes stay cool and damp well into what should be summer. Replacing old single-pane aluminum with low-E double-glazed units changes the feel of the house immediately. Rooms hold warmth, windows stop sweating, and the furnace doesn’t run as hard. We quote manufacturer lines side by side on paper so you see exactly what each upgrade costs and which one fits your house.

Trusted Brands We Service in Pacifica
We’re authorized installers for more than a dozen manufacturer lines, including. For Pacifica’s coastal exposure, we also work regularly with PGT and CGI for impact-rated glass, and ES Windows for higher-end custom work. We order directly from these manufacturers and register both warranty layers before our crew leaves your driveway. If you’ve had a contractor hand you a stack of paperwork and disappear, we’re the opposite. The warranty is in your hands, written, with durations stated, before we load the tools back on the truck.
Common Window Replacement Problems We See in Pacifica Homes
- Salt-air corrosion that seizes sashes shut. Within a few blocks of the coast, aluminum window frames can corrode to the point where they won’t open or close without a fight. Once the sash binds, the window is done. We replace it with materials built for salt exposure, typically fiberglass or vinyl with stainless hardware.
- Wind-driven rain getting behind the flashing. Pacifica’s coastal storms push water sideways, not down. A window that leaks only during storms usually wasn’t bedded and flashed to coastal standards. We pull back the trim, repair the rough opening if it’s soft, and reflash before the new unit goes in.
- Fogged glass that’s actually a failed seal. Persistent marine-layer condensation hides failed insulated glass units for years. Homeowners assume the fog is normal humidity. It’s not. When the argon is gone and the glass has lost its insulation value, the fix is a new unit, not a new dehumidifier.
- Rotted sills and framing from decades of damp air. The marine layer never burns off in Pacifica like it does inland. That constant moisture finds its way into wood sills and rough openings, and by the time you see the rot from inside, the framing behind the drywall is often worse. We write framing repair allowances into every quote so there are no surprises when the wall comes open.

FAQs - Window Replacement in Pacifica
Pacifica sits directly on the open Pacific coast with almost no geographic buffer, which makes the salt-air exposure here far more aggressive than anything a few miles inland. Salt-laden wind off the ocean attacks aluminum frames and hardware, and wind-driven rain finds every weakness in flashing and weatherstripping. In Daly City or San Francisco, a window might last thirty years. In Pacifica, the same window facing the bluffs is doing well to make fifteen. That’s not a quality issue. It’s geography. Call (888) 635-0804 and we’ll take a look at what you’re up against.
Condensation sits on the surface of the glass and wipes away with a cloth. A failed seal shows up as fog or haze between the glass panes that you can’t reach. Pacifica’s year-round marine layer makes this confusing because surface condensation is constant here. But if the fog is inside the unit, the seal is gone, the argon has escaped, and the window has lost most of its insulating value. The fix is a new insulated glass unit or a full replacement, depending on the frame condition.
Fiberglass and vinyl outlast aluminum in Pacifica’s coastal environment, period. Aluminum pits and corrodes within a few blocks of the water, and once the sashes start binding, the window is done. Vinyl is the most practical choice for most Pacifica homes, and fiberglass is the premium option when you want maximum strength and the longest service life. Wood requires constant maintenance in this climate. We quote both vinyl and fiberglass lines side by side so you can see the numbers and decide.
Because when we open up a 1950s or 1960s Pacifica home, we rarely find clean, dry framing behind the old window. Wind-driven rain, persistent marine-layer moisture, and decades of failed seals add up. We write allowances into the contract before we start so you’re not surprised if we find rot, and if the framing is fine, you pay less, not more. If something unexpected does come up, we price it in writing and get your approval before we touch it. No surprise line items. A square deal, in writing.
Yes, in many cases. When we pull a permit for window replacement on an older home, the inspector may flag egress requirements, tempered-glass requirements near doors and low sills, or structural anchoring upgrades that weren’t required when the house was built. It’s not a money grab. It’s the current code applying to work being done today. We pull permits, schedule inspections, and make sure the job passes before we call it done. Call (888) 635-0804 and we’ll walk you through what a permit will mean for your specific house.
