Why TruePane Windows & Doors Is Millbrae’s Preferred Window Replacement Company
TruePane was founded in 2008 by Dale Kessler, a second-generation glazier who built the company around a rule that’s been on the whiteboard since day one: if the pane is not true, the job is not done. That means every opening is measured twice, every warranty layer is registered in writing before the truck leaves your driveway, and every job carries our Done Right Promise. We don’t argue over what “done” means. We fix it.
Millbrae homeowners call us because our Window Replacement crews have worked the streets off Broadway, along Magnolia, and up into the hills near Mills Estate for years. We know the aluminum sliders that pitted out on the 1950s ranchers. We know the Craftsman bungalows with wood sashes that bind every winter. Background-checked, uniformed technicians show up when we say, quote manufacturer lines side by side on paper, and register both warranty layers before leaving. No second appointment left hanging.
Scheduling for Millbrae is coordinated from our San Francisco Bay Area office, and our crews serve 94030 directly. The phone number is (888) 635-0804. A live person picks up. Always.
Our Window Replacement Services in Millbrae
Full Frame Replacement
When the frame itself is rotted, racked, or so corroded the sash no longer seats, an insert won’t solve anything. We remove the entire old unit down to the rough opening, inspect the king and jack studs, install a new frame, flash it properly, and trim it out. On Millbrae ranchers where SFO’s sound program replaced some openings but not others, full-frame work lets us match sightlines and glass packages across the house.

Insert Window Replacement
For frames that are square and structurally sound, an insert keeps the existing trim intact and drops a new energy-efficient unit into the old frame. This is the most common replacement in Millbrae’s 1945-1970 housing stock, and it’s the most cost-effective path when the frame hasn’t been compromised by salt air or settling. We install Andersen 100 Series inserts regularly in this market, and the difference in both noise and draft reduction is immediate.

Storm Window Replacement
Some Millbrae homes, particularly older bungalows on the hillside, still carry exterior storm windows from a long-gone era. When the storms themselves are fogged, bent, or missing hardware, we replace them while preserving the primary sash behind. It’s a lower-cost option for historic homes where the original windows are part of the character, and it buys real thermal and acoustic improvement without altering the facade.

Energy-Efficient Upgrade
Millbrae’s marine layer keeps things cool most of the year, but those old single-pane aluminum sliders still bleed heat in winter and turn the afternoon sun into a bake in August. We quote low-E and argon-filled packages, often alongside laminated STC-rated glass for homes under the flight path. Both layers of manufacturer warranty are registered in writing, with durations stated, before we pull away from the curb.

Common Window Replacement Problems We See in Millbrae Homes
- Patchwork glass from SFO sound program grants. Millbrae homes often have three different window generations: original aluminum in the back, SFO laminated glass up front, and a mid-2000s retrofit in the kitchen. Matching sightlines, frame depths, and STC ratings across those openings is a local art, not a generic install.
- Pitted and corroded aluminum frames. Salt-laden bay air, even on sheltered streets, eats 1950s and 60s extrusions. We see sashes that bind mid-track, seals that fail early, and weep holes clogged solid. In Millbrae, corrosion is a when, not an if.
- Fogged insulated glass from failed seals. Early dual-pane units, especially on windows that were never part of the SFO retrofit program, lose their argon and fog internally. We replace the glass pack and shell when the frame is sound, or quote the full replacement when it isn’t.
- Craftsman-era wood sashes on the hillside. Fog, damp, and seasonal swelling cause wood double-hungs west of El Camino Real to stick, crack glazing compound, and lose weatherstripping. We restore what’s worth saving and replace what isn’t.
The Millbrae Window Challenge: SFO, Salt Air, and a Patchwork of Glass
Millbrae sits directly under SFO’s primary flight paths, and the FAA-funded Residential Sound Insulation Program has targeted Millbrae homes for acoustic-grade upgrades for decades. That’s a good thing for homeowners who got grant-funded laminated glass. It’s a complicated thing for anyone replacing windows today. Because the program ran in multiple grant cycles over many years, the average 1960s ranch in Millbrae can have original single-pane aluminum sliders in the back bedrooms, SFO-program laminated units in the front rooms, and a mid-2000s insert in the kitchen. Three generations. Three frame depths. Three glass packages. A straightforward “replace my windows” job turns into a matching and detailing problem that a generic window company from San Mateo or Redwood City simply doesn’t see often enough to get right.
We just finished a job off Murchison Drive on a 1964 ranch that had exactly this. The front elevation had SFO-program laminated glass from an early grant cycle. The back bedrooms still had original single-pane aluminum sliders that rattled on every departure. The owners wanted the noise gone and the look unified. Our crew pulled the old frames, installed Andersen 100 Series casement and picture windows with argon fill and low-E glass, and re-flashed every opening. Interior noise dropped a measurable 8 to 10 decibels. Sightlines matched. The warranty paperwork was registered in writing before we left. That’s a Millbrae job, through and through.
Pricing for Window Replacement in Millbrae, CA
A typical insert window replacement in Millbrae runs $850-$1,700 per opening for a standard-sized unit with low-E and argon. Full-frame replacement runs $1,400-$3,200 per opening, and that spread accounts for frame material, glass package, and whether the opening needs reframing or shimming. STC-rated laminated glass for homes directly under the flight path adds $250-$600 per opening over standard dual-pane. Energy-efficient upgrades, including low-E and argon packages, add $150-$400 per window depending on glass spec. Historic wood window restoration on hillside bungalows typically starts at $900 per sash and goes up based on the condition of the frame and trim. We give written line-item quotes before work starts.

FAQs - Window Replacement in Millbrae
If your windows are single-pane and your home is within the SFO noise contour, you may still qualify for a future grant cycle through the San Francisco International Airport’s Residential Sound Insulation Program, which is administered separately from any window company. The easiest check is to look at the glass: single-pane windows have one layer, no spacer bar between panes, and typically rattle or transmit conversation-level noise from outside. We can identify original units during a free estimate and tell you which openings would benefit from STC-rated laminated glass, whether or not you’re pursuing the program. Call (888) 635-0804 and we’ll take a look.
Yes. We quote laminated glass packages with STC ratings from 34 to 42, depending on the glass composition and frame type, and we match them to existing SFO-program units already in the house. That means we can bring your back bedrooms up to the same acoustic standard as your front rooms without ripping out the grant-funded windows that are still working. The key is measuring the existing units precisely and ordering glass that matches both the thickness and the air space. We do this on nearly every Millbrae job where the sound program touched part of the house. Call (888) 635-0804 for specifics on your home.
Salt-laden marine air from the bay accelerates oxidation on bare and painted aluminum extrusions, especially on 1950s and 1960s frames that were never anodized or powder-coated to modern standards. Millbrae’s persistent marine layer, even when the sun is out elsewhere, keeps surfaces damp long enough for chloride to eat into the metal. The result is pitting, swelling at the corners, seized sashes, and failed seals. Replacement with properly coated frames, or full-frame vinyl or fiberglass, eliminates the cycle. Call (888) 635-0804 and we’ll tell you what you’re dealing with.
Often, yes. Swollen wood sashes from seasonal fog and damp are a common Millbrae hillside issue, but if the wood isn’t rotted and the joinery is intact, we can plane, re-glaze, and replace the weatherstripping to get them operating smoothly. Where the frame has twisted beyond repair or the sills have rotted from trapped moisture, restoration stops making financial sense and we’ll tell you so. We restore what’s worth restoring and replace what isn’t. Estimates are free.
Fog between panes means the insulated glass unit’s seal has failed and the inert gas has escaped, leaving moisture inside the air space. It’s common in Millbrae homes with early dual-pane windows that were never part of the SFO retrofit program, and the constant temperature swings from bay fog to afternoon sun accelerate seal fatigue. The fix is replacing the glass pack, or the entire sash if the frame has also degraded. Call (888) 635-0804 and we’ll tell you what needs to happen for your specific windows.
