Windows & Doors Services in Covina, CA
If you own one of the post-war tract homes that fill Covina’s 91722 zip code, you already know the drill: original aluminum sliders that rattle in a Santa Ana wind, a patio door that binds every July, and a bathroom window that hasn’t sealed right since the Reagan administration. TruePane Windows & Doors handles installation, replacement, and repair work throughout Covina with crews who know these houses because they’ve worked on hundreds of them. When you call (888) 635-0804, a live person answers. We’ll schedule a time, show up in a marked truck, and measure every opening twice before we quote you a number you can hold us to. No call center, no voicemail tree, no waiting three days for a callback.

Why Covina Homeowners Choose TruePane Windows & Doors
Most of our Covina customers have lived in their homes for twenty, thirty, sometimes forty years. They remember the contractor who installed a window slightly out of square and disappeared when the fogged seal showed up two winters later. That’s the problem TruePane was built to solve. Dale Kessler founded this company on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. Every install in Covina is covered by our Done Right Promise, backed by The Keystone Standard: both manufacturer warranty layers registered in writing, with durations stated, before the truck leaves your driveway. We’ve worked on ranch homes north of Badillo Street, minimal-traditional tracts near Covina Park, and mid-century originals up toward Citrus Avenue. The houses change; the standard doesn’t.
Windows & Doors Services We Offer in Covina
Window Installation
New-construction or retrofit, we set windows level and plumb the first time. On Covina’s stucco ranch homes, that often means correcting rough openings that haven’t been touched since Eisenhower was in office.

Door Installation
A door that binds in August or lets drafts through in December isn’t doing its job. We install entry doors, French doors, and Sliding & Patio Doors in Covina built for the San Gabriel Valley’s heat and wind, not for a showroom in a mild climate.

Window Replacement
Swapping 1960s aluminum sliders for modern dual-pane units changes how a Covina house holds temperature. We quote manufacturer lines side by side on paper so you see exactly what you’re buying and what it costs.

Impact Windows & Doors
For Covina homeowners who want protection beyond standard glass, we install Impact Windows & Doors in Covina from manufacturers including PGT and CGI. These hold up under repeated pressure cycling and flying debris, not just a stray baseball from a neighbor’s kid.

Energy-Efficient Windows
When Covina hits 104°F in August, your windows are either working for you or against you. Energy-Efficient Windows in Covina with Low-E glass and insulated frames cut the load on your air conditioner and meet California Title 24 requirements that old single-pane units never did.

Sliding & Patio Doors
Fifty-year-old sliders with worn rollers and failed seals are a Covina signature. We replace them with doors that glide, seal, and lock properly, whether you want a standard patio slider or a multi-panel opening onto a backyard.

Glass Railing Systems
For decks, balconies, and pool enclosures, we fabricate and install Glass Railing Systems in Covina from manufacturers like ES Windows and ECO Window Systems. Built to code, built to stay clear and solid for decades.

Custom Windows & Doors
Odd rough opening? Arch top? Jalousie bathroom window you finally want gone? We manufacture and install custom units to spec. This is where a second-generation glazier’s training shows, especially on Covina homes where nothing is square anymore.

Pricing for Windows & Doors in Covina
Here’s what Covina homeowners should expect to budget, based on work we’ve done across 91722. These are honest ranges; your quote depends on opening count, glass package, and frame condition.
- Window replacement, per opening (standard size, dual-pane, retrofit): $650-$1,450
- New-construction window installation, per opening: $850-$1,900
- Exterior door replacement (entry, standard swing): $1,800-$4,200
- Sliding patio door replacement (standard 6-foot): $2,300-$5,000
- Stucco repair and rough-opening correction (per opening, when needed): $250-$700
- Glass railing system, per linear foot (tempered, code-compliant): $220-$380
On Covina’s older homes, expect line items for stucco patching and frame modification. A good contractor tells you that before the job starts, not after the drywall is open. We do written line-item quotes with no change orders unless you change the scope. Call (888) 635-0804 for a free estimate on your specific house.
Why Covina’s Climate & Housing Affect Windows & Doors
Covina sits in the inland San Gabriel Valley heat basin, where summer temperatures run 15 to 20 degrees hotter than Santa Monica and routinely break 100°F. That heat does things to windows and doors. Vinyl frames that survive fine in coastal climates get brittle here. Caulk cracks. Weatherstripping turns to chalk. Original aluminum frames, set directly into stucco with no proper flange or weep system, conduct heat straight into the house and allow moisture into the wall cavity over decades. When we pull those frames, we frequently find crumbling substrate behind the stucco that has to be repaired before a new unit can go in. That’s a Covina-specific problem, and it’s exactly why we don’t give a final price over the phone before seeing the opening. The estimate is free; the surprise is what you’re trying to avoid.

FAQs About Windows & Doors in Covina
Most Covina homes we quote fall between $650 and $1,450 per standard window for dual-pane retrofit replacement, with higher costs when stucco repair or rough-opening correction is required. Your price depends on the glass package, frame type, and the condition of the existing opening. Call (888) 635-0804 for an exact quote. Estimates are free.
Not unless you change the scope. We write fixed, line-item quotes, and the number on the paper is the number on the bill, with no change orders we haven’t discussed with you first. If we find hidden damage when we pull an old Covina frame, we stop work, show you what we found, and get your sign-off before anything else happens.
When the City of Covina requires a permit for a window or door replacement, we pull it. We’re familiar with the local building department’s expectations and with California Title 24 energy compliance for replacement fenestration. Anything we install meets code, and the inspection passes before we call the job done.
For a typical single-story ranch with eight to twelve openings, most jobs complete in one to two days on site. Larger projects or homes with significant stucco work and rough-opening corrections can run longer. We’ll tell you the schedule in writing before we start, and we’ll be there when we say.
Yes. We offer a permanent 5% discount for seniors and veterans, plus a free written repair estimate and a maintenance check for windows and doors. These apply to Covina work just like everywhere else we serve. Call (888) 635-0804 and mention what applies to you.

What Covina Customers Say
"Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T."Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P.
