Fast, Reliable Impact Windows & Doors Across Pomona
Impact windows and doors in Pomona, CA run between $85 and $150 per square foot installed, with most full-home retrofit projects landing in the $18,000 to $42,000 range depending on opening count and frame condition.

Our Impact Windows & Doors crew works Pomona’s older Craftsman blocks, the Garey Avenue corridor, and the ranch tracts north of Holt every week. Call (888) 635-0804 and we’ll scope the job properly, on paper, before you spend a dollar.
Why TruePane Windows & Doors Is Pomona’s Preferred Impact Windows & Doors Company
Dale Kessler founded TruePane in 2008 on a rule that still sits on the shop whiteboard: if the pane is not true, the job is not done. That’s not a slogan. It’s the standard our installers work to in every Pomona home, and it’s why we carry both manufacturer warranty layers registered in writing before the truck leaves your driveway.
Pomona’s housing stock is older and more varied than what you’ll find in Ontario or Chino. Pre-war Craftsman bungalows near Lincoln Park were framed to lumber dimensions that haven’t been standard since the late 1940s. That means a modern impact-rated sash rarely drops into an original opening without custom sizing, extension jambs, or both. Shops that cut their teeth on code-uniform tract stock struggle with this. We don’t. We’ve been through enough Pomona retrofits to know what’s behind the stucco before we open the wall.
Every tech who walks your property is background-checked and uniformed, and a live person answers our phone 24 hours a day. Our Pomona customers rate us on the work itself: clean flashing, square frames, operable sashes on the day we leave. We stand behind every install with the Done Right Promise. If it’s not right, we make it right. No paperwork fight, no “that’s not covered.”
If you’re reading this from Pomona, you’ve probably lived in your house for two decades, and you remember the contractor who fogged your last Andersen or left your patio door binding every July. We know that history shapes how you buy. So we quote manufacturer lines side by side on paper, measure every opening twice, and never spring a change order at the final walkthrough. Call (888) 635-0804. We answer.
Our Impact Windows & Doors Services in Pomona
Hurricane Impact Windows
A typical impact window replacement in Pomona runs $1,100 to $2,800 per opening installed, depending on size and whether we’re dealing with a pre-war rough opening or a uniform 1950s tract dimension. In the Craftsman-era blocks around Lincoln Park, those openings follow old lumber sizing, which means we’re custom-sizing the unit or building out extension jambs on almost every window. That’s the norm in this city, not the exception, and it’s why two identical-looking Pomona homes can carry very different bids. We measure every opening twice and show you exactly what you’re paying for before we order glass.
Impact-rated units for Pomona’s inland climate should carry real low-E coatings and argon fill. Your summer afternoons top 100°F, and Santa Ana events push hard through the eastern passes. A cheap impact window with no low-E will stop wind-blown debris but bake your living room. We spec glass that does both jobs.

Impact Sliding Glass Doors
Impact sliding glass doors in Pomona usually run $4,500 to $9,200 installed, with wider or multi-panel units going up from there. This is one of the sub-services we emphasize in this city because the older ranch homes along Garey Avenue almost always have original aluminum sliders that have racked out of square from decades of Santa Ana pressure. When that frame racks, the new impact-rated panel will bind and the weatherstripping will fail at the corner joints.
We don’t drop an impact slider into a racked opening and call it done. We square the rough opening, flash the full perimeter, and set fusion-welded frames from manufacturers like Milgard or ES Windows that hold their line through Pomona’s thermal swings. If your slider is on a detached ADU or workshop, we check the flashing detail under county setback rules and correct it before we set the door.

Impact Entry & French Doors
Impact entry doors in Pomona run $3,800 to $8,500, and French door pairs run $7,000 to $15,000 depending on width, glass cuts, and whether we’re rebuilding the threshold. Pre-war bungalows and Spanish Colonial Revival homes from the 1920s and 1930s often have non-standard door heights. The modern 80-inch slab doesn’t always fit without modifying the header detail, and that’s work we scope during the estimate visit, not after demo starts.
We recommend impact French doors with reinforced multi-point locking hardware on any Pomona home that catches full western exposure or sits in a wind-funnel path near the 10 or 57 corridors. Wind mitigation compliance matters to your homeowner’s insurance, and we document every install. Both warranty layers get registered in writing before we roll the truck out of your driveway.

Impact Garage Doors
Impact-rated garage doors in Pomona cost $2,800 to $6,400 installed, with taller or wider openings in older detached garages running higher due to reinforcement work. Garages built in the 1920s through 1950s often sit on slab foundations that have shifted, tweaking the side tracks. We set the tracks to true vertical and reinforce the header before hanging an impact door. Skipping that step means a door that shudders in every wind event and binds by your second Pomona summer.
Springs and cables on an impact garage door carry serious tension. If you hear a snap or the door hangs unevenly, call us. Don’t try to adjust that hardware yourself. We’ll send a tech who knows how to handle the tension safely.

Common Impact Windows & Doors Problems We See in Pomona Homes
- Fogged glass between panes. In Pomona’s temperature swings, a failed seal shows up fast. When outdoor temps swing from 102°F afternoons to 35°F winter nights, any weak seal lets moisture in and fogs the unit. If your glass is fogging, the seal is dead. The glass needs replacing, not the whole frame in most cases.
- Warped or racked pre-war sash. Craftsman-era wood windows around Lincoln Park warp under repeated Santa Ana pressure. The sash pulls out of square, the impact glazing seal fails within two summers, and the window starts rattling and leaking. We reinforce the frame before setting new glass.
- Oxidized aluminum frames on 1950s ranches. Pomona’s smog and inland air chemistry oxidizes old aluminum frames and hazes the metal. Casement and double-hung sashes bind long before the glass fails. The fix is a full frame replacement or a sash retrofit sized to your opening, not a lube job.
- Water intrusion around impact sliders on detached ADUs. Detached workshops and ADUs built under older county standards often lack proper flashing at the sliding-door jamb. Winter storms drive water into the wall cavity, and you don’t see it until the stucco stains. We flash the full perimeter and correct the drainage plane before the new door goes in.

FAQs - Impact Windows & Doors in Pomona
Homes on Pomona acreage that falls under county jurisdiction go through Los Angeles County building and safety for permitting, and the process accounts for septic and well setbacks, which can restrict how close a new impact slider can sit to an existing leach line or wellhead. A tract home inside city limits uses City of Pomona permits, which are tied to the city’s current residential code. We coordinate both. We’ve pulled permits for detached structures, additions, and whole-house retrofits in 91766, and we confirm which jurisdiction applies before we quote the job.
Yes. You can upgrade a detached workshop, ADU, or outbuilding independently of the main house, and many Pomona homeowners do this first because a detached structure’s old single-pane aluminum windows fail faster in the inland heat. The key is making sure the new impact units are flashed to modern standards and the rough openings are properly squared, especially if the building predates uniform county codes. We’ve done exactly this on 1950s ranch properties off Garey Avenue. Call (888) 635-0804 if you want a separate quote for just the outbuilding.
Fog between panes means the seal is dead and the insulated glass unit has failed, plain and simple. In Pomona, the 100°F summer afternoons followed by 35°F winter nights put maximum stress on seals. Once moisture is inside the unit, the insulating gas has leaked out, and the window’s thermal performance is gone. The fix is replacing the glass unit, not the whole frame, in most cases. Call us for an exact quote on glass replacement versus full frame replacement.
Yes. Pomona’s air quality and Santa Ana wind events mean exterior flashing takes more abuse than in coastal cities. Wind-driven dust and high-ozone inland air accelerate seal degradation and get behind weak flashing details. We use full-perimeter flashing on every impact window and door, and we inspect the drainage plane before the unit is set. It’s standard on our Pomona jobs, not an upgrade line item. If you’ve had water staining or drafty frames, call (888) 635-0804 and we’ll scope it during the free estimate.
Most 1950s Pomona ranch homes can carry impact-rated sash weight if the rough openings are solid and the headers are intact, but the only way to know is to open the wall and inspect the framing during the estimate. We check the header, the jamb plumb, and the condition of the rough opening before we quote. In older parts of the house that have shifted or water-damaged framing, you may need localized framing repair rather than a full replacement. We’ll tell you what’s actually needed, not what pads the bid. Call (888) 635-0804 for a free estimate and we’ll give you the honest answer.
Call TruePane Windows & Doors at (888) 635-0804 for a free estimate on impact windows and doors in Pomona. We’ll measure every opening, scope the full job on paper, and register both warranty layers in writing before the truck leaves your driveway. If the pane is not true, the job is not done. That’s the standard. In Pomona, we stand behind it.
