AfterWindows & Doors Services in Pomona, CA
Window and door work in Pomona tends to come with a specific set of problems: warped wood sashes from summer heat, aluminum frames that bind after a Santa Ana wind event, fogged seals that never fully clear, and openings in older Craftsman homes that were built to dimensions no modern manufacturer stocks. TruePane Windows & Doors handles all of it. A live person answers our phone at (888) 635-0804 any hour, and the crews we send into Pomona neighborhoods know the housing stock here; they are not learning on your house. If you need window or door work done right, call us.

Why Pomona Homeowners Choose TruePane Windows & Doors
Dale Kessler started TruePane in 2008 with a rule that still governs every install: if the pane is not true, the job is not done. Since then, homeowners across Pomona, from the Craftsman-era streets around Lincoln Park to the post-war ranch tracts north of Holt Avenue, have called us for the same reason. They want a company that measures every opening twice, quotes manufacturer lines side by side on paper, and registers both warranty layers before the truck leaves the driveway. That is The Keystone Standard, and it is in writing on every job we do.
We are background-checked, uniformed, and insured. We hire locally and train apprentices into journeymen, because we plan to be answering the phone in Pomona thirty years from now. And when something is not right, the Done Right Promise applies: we make it right, no paperwork fights and no arguing.
Windows & Doors Services We Offer in Pomona
Window Installation
New construction or retrofit, standard sizes or the odd rough openings found throughout 91766, we install windows that sit square and seal tight. In Pomona’s older homes, custom sizing is often the difference between a window that lasts and one that leaks air from day one.
Learn more about our Window Installation in Pomona.
Door Installation
Entry doors, interior doors, and exterior door frames take real punishment in Pomona, especially during Santa Ana wind events that push dust and debris against every west-facing opening. We set doors so they close true and stay that way through the seasons.

Window Replacement
Single-pane wood sash windows from the 1930s and 1940s cannot keep up with Pomona Valley summer heat or winter cold snaps. We replace them with energy-efficient units sized correctly to the opening, including the non-standard frames common in pre-war bungalows.

Impact Windows & Doors
Pomona does not sit on the coast, but wind-driven debris during Santa Ana events is a real concern for homeowners here. Impact Windows & Doors in Pomona from manufacturers like PGT and CGI give you protection without sacrificing light or function.
Energy-Efficient Windows
With summer afternoons in the Pomona Valley regularly crossing 100°F, Energy-Efficient Windows in Pomona with low-E glass and proper frame insulation cut cooling costs measurably. We quote manufacturer lines side by side so you see the actual performance ratings before you spend a dollar.
Sliding & Patio Doors
Pomona’s diurnal temperature swings cause aluminum patio door tracks to expand, contract, and eventually rack out of alignment. We install and service Sliding & Patio Doors in Pomona that glide cleanly in July and still operate smoothly when January nights drop near freezing.
Glass Railing Systems
For decks, balconies, and stairwells, we fabricate and install Glass Railing Systems in Pomona that meet code and hold up to the sun exposure without hazing or yellowing.
Custom Windows & Doors
When an opening does not match any standard size, which happens constantly in Pomona’s 1920s and 1930s housing stock, we build to fit. Custom does not mean slow; it means correct.
Neighborhoods We Serve in Pomona
Our crews work throughout Pomona and the 91766 zip code. We are regularly in these neighborhoods:
- Lincoln Park and the Craftsman-era streets around it
- The ranch-style tracts north of Holt Avenue
- Westmont and the neighborhoods near Garey Avenue
- Phillips Ranch, including newer construction around the hills
- Downtown Pomona, where mixed commercial and residential buildings present their own set of window and entry door challenges
Most visits are scheduled within the same week, and we arrive when we say we will.
Why Pomona’s Climate & Housing Affect Windows & Doors
Pomona sits in the inland heat basin of the Pomona Valley, where summer afternoons routinely top 100°F and winter nights can dip near freezing. That thermal range is far more extreme than what coastal cities or even mid-San Gabriel Valley towns experience, and it puts steady stress on window seals, wood sashes, and aluminum frames. Seal failure, oxidation, and warping happen faster here than in Pasadena or Glendora. On top of the heat, Pomona is one of the worst air-quality pockets in the greater LA basin, as prevailing winds funnel smog and particulates eastward and trap them against the foothills. Good windows in Pomona are doing two jobs at once: keeping heat where it belongs and keeping the air inside your house cleaner.
Then there is the housing stock. Pomona has one of the older, more diverse inventories in the eastern San Gabriel Valley, with Craftsman bungalows and Spanish Colonial Revival homes from the 1920s and 1930s alongside post-war ranch tracts from the 1950s. In the older blocks around Lincoln Park, we routinely find window openings sized to pre-war lumber dimensions and non-metric sash standards. A modern replacement unit almost never drops straight in. That is exactly the kind of job where an experienced Pomona installer is worth the difference, because custom-sizing or site-built extensions are the norm, not the exception.

When the City of Pomona requires a permit for structural changes, we pull them and pass inspection before considering the job done. For straightforward replacements, permits are typically not required, but we will tell you up front either way.
No. We quote line by line, in writing, before any work begins. If we find hidden damage during the job, we stop and show you before doing anything else. The Done Right Promise covers our workmanship, and there are no surprise line items on the bill.
Most single window replacements and entry door installs are completed in one visit, usually the same day. Custom work on pre-war openings or multi-unit jobs takes longer, and we will give you a written timeline before we start.
Yes. We custom-size or build site extensions for the non-standard rough openings common in 1920s and 1930s Pomona houses. This is not a job for a shop used to code-uniform tract homes, and we have the experience to do it correctly. Call (888) 635-0804 to talk through your specific openings.

What Pomona Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A.
