Fast, Reliable Impact Windows & Doors Across Napa
Impact windows and doors in Napa are not a luxury add-on. They’re the difference between a house that rides out the next earthquake and windstorm intact, and one that loses a wall of glass to flying debris or seismic racking. Our Impact Windows & Doors team has spent years working on homes across Napa’s older west-side neighborhoods, where the 2014 South Napa Earthquake left door frames and window openings out of square in ways that still show up on service calls today. If you need a straight answer about impact-rated glass, code compliance, or why your French doors stopped latching, call (888) 635-0804 and you’ll get a live person, not a menu.
Why TruePane Windows & Doors Is Napa’s Preferred Impact Windows & Doors Company
We were founded in 2008 by Dale Kessler, a second-generation glazier, on a rule that governs every job: if the pane is not true, the job is not done. That rule matters especially in Napa, where the 2014 quake moved rough openings in thousands of homes and left a legacy of doors that drag and windows that bind. A crew that doesn’t understand seismic racking will shim a new unit and call it good. We won’t.
Our Napa customers call us because we show up when we say, in uniform, with tools calibrated and materials matched to the job. We quote manufacturer lines side by side on paper, so you can see exactly what you’re buying before you commit. Both warranty layers get registered in writing before the truck leaves your driveway. That’s The Keystone Standard, and it’s backed by our Done Right Promise: if it’s not done right, we make it right. No paperwork fights, no fine print that covers neither.
Dale Kessler still personally reviews every estimate that goes out to a Napa address. That’s not a marketing claim. It’s how we’ve operated since 2008 of combined glazing craft in the Bay Area.
Our Impact Windows & Doors Services in Napa
Hurricane Impact Windows
Most people in Napa think of earthquakes before hurricanes, but the same impact-rated glass that meets Miami-Dade wind standards also holds its integrity when a quake torques a frame. We install impact windows from PGT, CGI, and Ply Gem, sized and squared to the opening they’re going into, not the opening that was there in 2013. On a 1960s ranch near Alameda Street, our crew saw an impact-rated double-hung that would not latch. The rough opening had racked during the 2014 quake and the prior installer had shimmed it on the sash side but never corrected the toe-to-header diagonal. We pulled the unit, resquared the jamb with structural shims and flashing tape, and reset a Simonton fusion-welded frame with argon-fill low-E glass. The window now seats dead-level and seals the way the label intended.

Impact Sliding Glass Doors
Sliding glass doors take the worst of Napa’s diurnal temperature swings, especially on south and west elevations where afternoon sun bakes the track and frame. Impact-rated sliders need precise installation because any pre-existing rack in the opening gets multiplied across a six or eight foot span. We set the track dead-level, square the jambs, and bed the frame so the panel travels smooth from day one. In Napa’s newer east side and wine estate corridors, where wide picture sliders open onto patios, we also handle the architectural glass upgrades that preserve sightlines without giving up impact protection.

Impact Entry & French Doors
French door pairs are the single most common failure we see in Napa’s older homes. The 2014 quake racked the rough opening; the astragal no longer seats, the multi-point lock strips, and the doors drag on the threshold. Installing a new impact-rated pair without resquaring the jamb first is a temporary fix at best. We resquare the entire opening, set the frame with structural anchors, and hang doors that close with one finger and lock with one motion. Impact-rated entry doors from PGT and CGI give you the forced-entry protection and the code compliance paperwork to match.

Impact Garage Doors
Garage doors are the largest opening in most Napa homes and the first thing wind pressure finds. We install and retrofit impact-rated garage doors that meet current wind load requirements, and we coordinate the track and opener work so the door operates like it should. Many Napa homes built before 1980 have undersized headers over the garage opening; we flag that during the estimate, not after the door is ordered.

Hurricane Shutters & Protection
For some Napa homes, especially the Victorian and Craftsman properties near downtown, full impact window replacement isn’t the right call. Hurricane shutters and panel systems offer protection without changing the architectural character of the home. We source and install shutter systems from CWS, sized to the specific window openings and finished to hold paint and hardware without rusting in Napa’s fog-and-sun cycles.

Wind Mitigation & Code Compliance
Napa’s building code requirements for wind-rated openings have tightened since 2014, and insurance carriers now ask for documentation that windows and doors meet current standards. We handle the wind mitigation inspections, the paperwork, and the install. If your insurer wants a specific form signed or a specific test result on file, we take care of it. Our team knows the Napa permit counter and what inspectors here actually check when they walk a project.

Common Impact Windows & Doors Problems We See in Napa Homes
- Post-quake racking that never got fixed. A 2014 South Napa Earthquake rack event shifted the rough opening; the prior owner hired someone who shimmed the visible gap and moved on. The new impact window or door then sits in an opening that’s out of square, so latches fail and seals tear within a few seasons.
- IGU seal failure on west-facing glass. Napa Valley’s extreme temperature swings, days near 100°F and nights in the 50s, expand and contract insulating glass units aggressively. Fog appears between the panes within five to seven seasons on exposed elevations. Impact glass with a failed seal loses both its energy performance and its structural rating integrity.
- Wood sills and frames that check, split, and cup. Napa’s dry summer heat pulls moisture out of wood frames faster than coastal cities just 30 miles southwest. Older double-hungs and picture windows develop warped jambs, and sashes bind even when no quake damage is present.
- French door pairs out of square. The rough opening shifts during a seismic event; the doors start to drag, the astragal won’t seat, and the multi-point lock strips within a season or two. Replacing the door without resquaring the jamb means the new door starts failing immediately.
Pricing for Impact Windows & Doors in Napa, CA
Impact window installation in Napa typically runs $90 to $180 per square foot of glass, depending on the manufacturer line, the frame material, and whether we’re resquaring the opening. A standard impact entry door starts around $2,800 to $4,500 installed. Impact sliding glass doors run $3,500 to $7,000 for most Napa homes, and wider architectural sliders on wine country properties can reach $9,000 or more. Impact French door pairs typically land between $4,500 and $8,500, and the price goes up when the rough opening needs structural resquaring, which it often does in Napa’s older housing stock. Impact garage doors start around $3,200 for a double-wide. Every estimate we produce is a fixed written line-item quote. The price we agree on is the price you pay.

Planning a High-End Impact Window Project? Read This First
On Napa’s wine estate homes and newer east side construction, impact windows and doors often go in as part of a larger architectural project. Custom millwork, cabinetry, designer hardware, and specialty finishes are part of the job, and we coordinate directly with your architect, designer, and general contractor. The long-lead items are not labor. They’re the manufacturer order queues and the custom glass packages. A custom impact-rated picture window in a wine country home might carry a 10 to 14 week lead time from the factory before it ships. A standard impact slider might be 3 to 5 weeks. We tell you the honest lead time up front, fix the price in writing before we order anything, and then hold to that price even if the manufacturer raises their rates mid-queue.
This page is the only Napa-specific impact windows and doors guide that treats post-2014 seismic racking as the primary installation variable, not a side note, because in Napa, the rough opening is rarely square until someone makes it square.

FAQs - Impact Windows & Doors in Napa
Yes, often they do. The glass can be perfectly intact while the sash, frame, or jamb has been torqued out of square by the 2014 quake. When that happens, the weather seals and latching hardware no longer seat correctly, and the window’s wind rating is compromised. The unit may look fine but fail under the next wind or seismic load. We inspect the opening, not just the glass. Call (888) 635-0804 and we’ll tell you what’s actually wrong.
Napa Valley’s diurnal temperature swings are far more extreme than Marin’s coastal climate. Summer afternoons in the upper 90s followed by nights in the low 50s put aggressive expansion-contraction cycles on insulating glass seals. The seals fail, argon escapes, and moisture gets pulled between the panes. West-facing windows in particular show this within five to seven seasons in Napa. A failed seal also degrades the impact glass’s structural rating, so the fix is a replacement, not a wipe-down. Call (888) 635-0804 for a free inspection.
Racking from the 2014 Napa earthquake shows up as a door that drags unevenly, won’t latch at the top but latches at the bottom, or has a visible gap at one corner of the frame. Normal settlement tends to be gradual and uniform. Racking is sudden and uneven. In Napa’s older west-side neighborhoods, most sticking doors we see are racking, not settling. The fix is resquaring the rough opening before installing or re-hanging the door. Call (888) 635-0804 and we’ll check it.
Yes. We coordinate with your millworker and install the impact-rated unit first, then set the custom trim and casing around it. The warranty on the window itself remains intact as long as the unit is installed to the manufacturer’s written spec, which we do on every job. The millwork is your custom work, and we document the installation so the manufacturer’s field inspector sees a clean pass. This is standard practice for us on Napa’s older Craftsman and Victorian homes near downtown.
Lead times, full stop. Custom impact glass packages and specialty frame profiles can run 10 to 14 weeks from the factory. Our labor schedule is typically flexible within a week or two once the product lands. We give you the real lead time in writing before you commit, and we order the product as soon as the deposit clears. If a manufacturer delays, we tell you immediately. What we don’t do is promise a date we can’t hold. Call (888) 635-0804 and we’ll walk you through the timeline for your specific project.
If you’re in Napa and need impact windows or doors, or just want a straight answer from someone who knows what the 2014 quake did to this town’s rough openings, call (888) 635-0804. We’ll answer live, schedule a free estimate, and show up when we say. A square deal, in writing, done right.
