AfterWindows & Doors in Pomona, CA
Window installation in Pomona means working around two forces that most LA County contractors never confront: extreme inland heat and a housing stock dominated by pre-1960 steel casement and aluminum-frame windows that are no longer manufactured in standard sizes. That combination turns what looks like a simple swap into a measured, often custom, project. If you live in a citrus-era Craftsman near Lincoln Park or a 1950s tract home in the Wilkerson Tract, your replacement windows almost certainly need full-frame work, not pocket inserts. Call us at (509) 265-6387 for a written, line-item price before any work starts.
We’re Sightline Windows & Doors, and we don’t sell from a brochure. We measure first, hand you the survey, and the written quote you receive is the same document we invoice against. That’s the Haven Standard.
Why Pomona Homes Are Different
Pomona sits at the eastern mouth of the San Gabriel Valley, where summer highs run 103°F to 108°F and stay there for weeks. That sustained heat bakes window seals, dries out door weatherstripping, and warps vinyl frames faster than in coastal cities. Then the Santa Anas arrive, funnelling down the valley floor and pushing dust and pressure through every gap in a threshold or sash. Homes built during the 1910s through 1940s citrus boom often still have their original single-pane steel casement windows, which bow and corrode under the dry heat yet are not allowed to be casually swapped if the home sits within the Lincoln Park Historic District. The city’s design guidelines require replacement units to match the original profile and material character. If a homeowner doesn’t know that before the first cut, the project stalls at the permit counter.
A later wave of 1950s and 1960s tract construction added jalousie and louvered aluminum windows to the mix. Those units are almost impossible to make airtight without removing the frame entirely. In Pomona, a window job is frequently a full-frame replacement job, whether or not anyone planned for that on day one.
Our Main Pomona Services
Two services generate the majority of calls from Pomona homeowners. Both are covered in dedicated pages with full local pricing.
Door Installation in Pomona
Door installation in Pomona often involves ungluing a threshold that has warped after a decade of 100°F summers and then re-setting it so that Santa Ana winds don’t whistle through the gap. We measure slab, rough opening, and sill, then write a quote that includes shimming, sealing, and hardware. Many Pomona entry doors are non-standard sizes from the citrus era, which is why we inventory non-standard slabs and frame stock locally. See the full breakdown on our Door Installation in Pomona page.
Window Replacement in Pomona
Window replacement in Pomona turns on one question: is the existing frame steel or aluminum? Steel casements in the Lincoln Park Historic District require custom profiles and city review. Aluminum jalousies from the 1950s almost always require full-frame replacement. We document every step, from frame readings to final photo record. Read the full local guide at Window Replacement in Pomona.

BeforeAfterWindow Installation in Pomona
Window installation in Pomona typically costs between $550 and $1,850 per window, with most 3-bedroom homes landing between $9,000 and $22,000 for a full-house project. The local complication is the frame situation: citrus-era steel casements and 1950s jalousie aluminum units require full-frame removal, custom sizing, and often a permit consultation that never comes up in newer cities. Our Window Installation process starts with a measured survey you keep.
Single & Double Hung Windows
Signs you need it
Sashes that drop, rattle in wind, or refuse to stay open are common in Pomona’s older bungalows, where original counterweight systems have been painted shut for decades.
What it costs in Pomona
Single and double hung windows run $550 to $1,250 per opening on standard sizes, and $900 to $1,800 for full-frame replacement in pre-1940 homes.
How we do it
We remove the old sash and frame, measure the rough opening, check for square, install a new unit with interior stops, then seal and trim to the original profile where a historic roof line or district rule applies.
Casement Windows
Signs you need it
Crank mechanisms seized, bent stay arms, or visible bowing of the steel sash signal that a casement window has failed or is near failure.
What it costs in Pomona
Casement replacement runs $700 to $1,700 per window, with custom steel casement replacements for Lincoln Park Historic District homes starting around $1,200 and going up from there.
How we do it
We document the original sightline and reveal, source or fabricate a unit that matches the profile, then install with the same crank or lever hardware orientation the city requires.
What Window Installation Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Standard single or double hung window | $550 - $1,250 |
| Casement window (standard size) | $700 - $1,700 |
| Full-frame replacement in pre-1940 home | $900 - $1,850 per opening |
Are permits required for window replacement in Pomona?
Yes, in many cases. If the home is within the Lincoln Park Historic District, replacement windows must match the original profile and material character, and city review is required before installation. Non-historic homes still need structural and egress compliance. We handle the paperwork and inspections.
How long does full-frame window installation take in Pomona?
Most full-frame replacements take one to two days per window once custom units arrive. Historic district custom fabrication can add three to six weeks of lead time. Your written quote includes the schedule. Call (509) 265-6387 for specifics on your opening.
Impact Windows & Doors in Pomona
Impact windows in Pomona are less about hurricanes and more about airborne debris during Santa Ana wind events, plus year-round UV and break-in resistance. In a city where wood-framed bungalows sit close to neighbors and where wind-driven dust can turn a cracked pane into a failure, impact-rated glass is a practical choice. Our Impact Windows & Doors installs run from $950 to $2,800 per opening depending on frame and glass package.
Impact-Resistant Windows
Signs you need it
Panels that flex or vibrate visibly in high wind, or windows that are the only penetration point on a ground floor, are the main triggers Pomona homeowners give us.
What it costs in Pomona
Impact-resistant windows run $950 to $2,400 per window in standard sizes, with full-frame work in older Pomona homes adding $400 to $700 per opening.
How we do it
We measure the existing frame and sightline, specify an impact-rated laminate and frame combination, then install with upgraded anchors and sealant designed for sustained pressure differentials.
Horizontal Roller & Sliding Impact Windows
Signs you need it
Roller tracks that bind, glass that rattles against the frame, and visible air gaps at the meeting rail are the signs we see most on Pomona’s mid-century homes.
What it costs in Pomona
Horizontal roller impact windows run $1,000 to $2,800 per unit, with wider 3-panel configurations at the top of that range.
How we do it
We replace the entire track, rollers, and glass pack as one assembly, then re-shim the frame to remove the pressure gaps that Santa Ana winds exploit.
What Impact Windows & Doors Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Impact-resistant window (standard) | $950 - $2,400 |
| Horizontal roller impact window | $1,000 - $2,800 |
| Full-frame impact window in pre-1960 home | $1,350 - $2,800 |
Do impact windows help with Pomona’s heat, or just wind?
Impact windows in Pomona pair a laminated glass layer with a low-E coating on most configurations. That means the same unit that stops wind-borne debris also cuts solar heat gain. Call (509) 265-6387 and we’ll write out the U-factor and SHGC numbers for your specific exposure.
Will impact windows look out of place on a Craftsman home?
No. We can specify impact-rated glass inside a frame that matches the original wood or painted steel sightline. The visible profile stays close to period-correct; the glass does the work. Historic districts in Pomona can approve this combination, and we walk the variance path when one is required.
Energy-Efficient Windows in Pomona
Energy-efficient windows in Pomona pay for themselves faster than in almost any other LA County market because the cooling season is so long and so intense. A home with single-pane steel casements can lose 30% of its cooled air through the glass and frames, and in a summer that starts in May and ends in October that shows up on every SCE bill. Our Energy-Efficient Windows runs from $600 to $1,800 per opening depending on glass package.
Low-E & Argon Gas Glass
Signs you need it
Rooms that are 10 degrees hotter than the rest of the house by 3 p.m., or glass that is hot to the touch from the inside, are the two signs we hear about most.
What it costs in Pomona
Low-E with argon gas runs $600 to $1,400 per window in standard sizes, and $900 to $1,800 in full-frame replacements.
How we do it
We spec the low-E coating and argon fill for the window’s orientation, then install with a full perimeter seal so the glass performance isn’t undone by air leakage.
UV-Blocking & Fade Protection
Signs you need it
Faded hardwood floors, bleached upholstery, or blinds that yellow within a few years all point to untreated UV exposure through the windows.
What it costs in Pomona
UV-blocking glass packages add $100 to $300 per window over standard low-E, putting most Pomona windows between $700 and $1,700.
How we do it
We identify which windows take direct afternoon sun, then specify a UV-blocking laminate or coating on those openings only, keeping the cost where the damage is.
What Energy-Efficient Windows Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Low-E argon gas window (standard) | $600 - $1,400 |
| UV-blocking glass package | $700 - $1,700 |
| Full-frame energy-efficient window | $900 - $1,800 |
Which energy package makes sense for Pomona’s climate?
A low-E coating tuned for solar heat gain, not winter heat retention, is the right call in Pomona. Look for an SHGC under 0.25 on west and south walls. We’ll write the exact numbers into your quote. Call (509) 265-6387 to schedule a measured survey.
Will energy-efficient windows stop the dust during Santa Anas?
They’ll help, but only if the frame and threshold are sealed as part of the install. Old frames leak around the edges even with good glass. Our full-frame approach deals with both. The written price includes the sealing, not just the glass swap.
Sliding & Patio Doors in Pomona
Sliding and patio door replacement in Pomona usually starts because a door no longer locks, no longer slides, or no longer keeps the wind out. On 1950s and 1960s tract homes, the original aluminum sliders were never airtight to begin with, and after sixty years of heat and Santa Ana pressure the gaps are visible through the threshold. Our Sliding & Patio Doors work runs $2,200 to $6,500 for typical replacement, with impact packages higher.
Sliding Glass Door Replacement
Signs you need it
A slider that takes two hands to move, lets dust in at the corners, or won’t latch is past service, and Pomona’s wind will keep finding any gap.
What it costs in Pomona
Sliding glass door replacement in Pomona runs $2,200 to $4,800 for a standard 6-foot unit, with wider or custom openings above $5,000.
How we do it
We remove the old frame, check the rough opening for square and water damage, then set the new track and panels level with the interior floor so the threshold is flush and sealed.
Impact Sliding Glass Doors
Signs you need it
Ground-floor sliders on rear yards or south-facing walls take the full force of Pomona’s valley winds, and if the glass flexes when you press it, it’s time.
What it costs in Pomona
Impact sliding glass doors run $3,800 to $6,500 for standard sizes, and more for 3-panel or oversized configurations.
How we do it
We specify a laminated impact glass pack and a reinforced frame, then install with wind-load anchors that hold under the pressure differentials we see in the Pomona Valley.
What Sliding & Patio Doors Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Standard sliding glass door | $2,200 - $4,800 |
| Impact sliding glass door | $3,800 - $6,500 |
| Custom or oversized 3-panel slider | $5,000 - $8,000 |
Why do patio doors in Pomona fail faster than doors on the coast?
The heat dries out the weatherstripping and track lubrication, then the Santa Anas force dust into the track and against the seals. A door that lasts 25 years in a coastal city can die in 12 here. Replacing the full frame, not just the panel, fixes that cycle. Call (509) 265-6387 for a written quote.
Can you install a new sliding door in a 1920s home without ruining the look?
Yes, on most rear elevations. The patio side of a Craftsman bungalow is rarely the street-facing elevation the city reviews. We match the new door’s color and sightline to the rest of the rear wall, and keep the work documented for the permit file.
Impact Garage Doors in Pomona
Impact garage doors in Pomona serve two purposes at once: they hold up to the wind loads that run through the valley during Santa Anas, and they turn the garage from the weakest wall of the house into a secured one. Most attached garages in Pomona are older wood or thin steel doors with no rating at all. Our Impact Garage Doors replacement runs $2,500 to $6,000, including wind-load code compliance.
Hurricane-Rated Garage Doors
Signs you need it
A door that bows inward under wind pressure, a track that flexes, or a door that’s original to a 1960s home and never rated for anything beyond its own weight.
What it costs in Pomona
Hurricane-rated garage doors run $2,500 to $5,500 for a standard 2-car door, with higher wind-load ratings adding to the cost.
How we do it
We measure the opening and the existing track mounting, specify a reinforced door and heavier track system, then install anchors and a header reinforcing plate where the opening requires it.
Energy-Efficient Garage Doors
Signs you need it
An attached garage that stays 100°F inside into the evening, or a bedroom above the garage that never cools, is the typical Pomona situation.
What it costs in Pomona
Insulated energy-efficient garage doors run $2,200 to $4,200 depending on panel thickness and finish, installed.
How we do it
We replace the door with an insulated core and new perimeter seals, then adjust the opener and tracks so the door seats fully against the jamb.
What Impact Garage Doors Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Hurricane-rated garage door (2-car) | $2,500 - $5,500 |
| Energy-efficient insulated garage door | $2,200 - $4,200 |
| Wind-load code compliance and reinforcment | $400 - $1,000 |
Does Pomona require wind-load rated garage doors?
Pomona’s building code requires garage doors to meet specific wind-load standards, which most original doors from the 1960s do not. When we replace, we bring the opening into current compliance and document it for inspection. Call (509) 265-6387 to get a written scope for your door.
How long does impact garage door installation take?
Most replacements take one day, including track and opener re-setting. If the opening needs header reinforcement, add a second day. The timeline is part of the written quote before we start.
Custom & Geometric Windows in Pomona
Custom and geometric windows in Pomona usually come up in one of two places: a Lincoln Park Historic District home where the original arched or shaped opening must be matched, or a mid-century home where an original picture window has been boarded over or poorly replaced. Neither case works with stock sizing. Our Custom & Geometric Windows installations run from $1,200 to $4,500 per opening depending on shape, glass, and frame.
Geometric & Shaped Windows
Signs you need it
An opening that’s not a rectangle, and that has been filled with drywall or a too-small stock window, is the clearest sign you need a custom unit.
What it costs in Pomona
Geometric and shaped windows run $1,500 to $4,500 per unit, with the price set by the number of angles, degree of arc, and glass type.
How we do it
We measure the opening with a digital template, send the shape to the fabricator, and install the resulting unit with the same sightline and reveal as the original.
Arched & Curved Windows
Signs you need it
A sagging arch, water staining below the sill, or an original arched window that has already been removed are the three situations we see in Pomona.
What it costs in Pomona
Arched and curved windows run $1,200 to $4,000 per unit, with true radius curves at the top of the range.
How we do it
We build the template from the actual opening, spec the correct glass and frame material, then anchor the new unit into the existing arch framing.
What Custom & Geometric Windows Costs in Pomona
| Item | Typical range in Pomona |
|---|---|
| Geometric or shaped window | $1,500 - $4,500 |
| Arched or curved window | $1,200 - $4,000 |
| Oversized custom opening | $2,000 - $6,000 |
Can you match a 1920s arched window in Pomona’s historic district?
Yes. We take a digital template of the original opening and fabricate a new unit that matches the radius, frame thickness, and sightline. Then we document it for the city’s historic review. Call (509) 265-6387 to start with a measured survey.
How long does a custom geometric window take?
Fabrication typically runs three to six weeks after we take the template. Installation itself is usually one day. Your written quote includes the fabrication lead time so you can plan around it.

"Patio door had dropped and would not lock. They adjusted it rather than selling me a new one, and charged accordingly."
- Simone T."The survey measurements and the quote were the same piece of paper. Nothing changed on install day, which is not what happened with the two other companies we had out."
- Annette R."Replaced eight windows. They showed me the U-factor on the units they were actually fitting rather than the brochure numbers."
