Windows & Doors in West Covina - Written Price Before Anything Is Ordered

Fast, Reliable Windows & Doors Across West Covina

Window replacement in West Covina runs $4,500-$15,000 for a typical ranch home, and impact window installation runs $8,000-$25,000 depending on how many openings you’re covering and whether we’re reframing the rough openings. Those numbers reflect what it actually costs to do the job right on 1950s and 1960s tract homes here, where single-pane aluminum frames are failing in lockstep and the clay soil underneath never quite stops moving. If you’re in the 91790, 91791, 91792, or 91793 zip codes and your windows are original to the house, you’re probably already feeling it: rooms that bake by 3 p.m., sashes that stick, stucco cracks spidering out from the window corners. Our Windows & Doors crews work West Covina weekly, and Tom Barrett’s sons run every job. Call (877) 610-1318 and we’ll walk the house with you and put a written scope in your hands before anything gets ordered.

Why Barrett & Sons Construction Is West Covina’s Preferred Windows & Doors Company

We started Barrett & Sons in 1998 as an owner-operated outfit, and that hasn’t changed. Tom Barrett’s name, address, and license number are published for anyone to look up before signing, and the crew members who show up at your door in West Covina carry the Barrett name, not a subcontractor’s badge. We answer our own phone, 24/7. When a homeowner near the South Hills neighborhood calls about a binding patio slider, they talk to a person who knows what a 1962 tract home rough opening looks like.

We’ve pulled permits and passed inspections with the West Covina Building & Safety Division enough times to know how their plan review flows, and we coordinate that with whatever else your house is cycling through: panel upgrades, re-pipes, seismic retrofits. That matters because most of the homes in this city are hitting all of those at once. You don’t want three contractors stepping on each other’s inspection dates. We handle the scheduling, the permit closeout, and the written change orders. Every price change arrives on paper before a single nail moves. That’s the 90-Day Done Right Promise working behind the scenes, and it’s written on every contract.

Our Windows & Doors Services in West Covina

Window Replacement

Most homes in West Covina’s original tracts were built with single-pane aluminum windows that are now 60 to 70 years old. The frames pit, the glass conducts heat like a griddle, and the uninsulated wall cavities around them leak air all day. We replace these with dual-pane low-E units sized to the actual rough opening, which on these older ranches is rarely a standard off-the-shelf dimension. We measure every opening, reframe where the framing has settled or cracked, and flash the sill so slab-on-grade moisture can’t wick into the subfloor. Full-home window replacement in West Covina typically lands between $4,500 and $15,000.

Door Installation

Entry doors on West Covina ranches take a beating from the inland heat. South-facing and west-facing doors warp, paint fails early, and the original thresholds often sit directly on a slab that’s moved seasonally for decades. We install pre-hung exterior doors with proper sill pans and backer rod, adjust interior doors that bind from slab heave, and reframe jambs when the old ones have sagged out of square. If your front door scrapes the floor every summer and frees up every winter, that’s the clay soil talking. We fix the opening, not just the door.

Impact Windows & Doors

The northern edge of West Covina, up near the San Gabriel foothills, sits in elevated Santa Ana wind and wildfire ember corridors. Homeowners along those streets are increasingly putting impact-rated windows and doors on their replacement lists, not because a hurricane is coming, but because embers find their way through failed frames and wind-driven debris cracks glass. Impact window installation runs $8,000-$25,000 depending on opening count and whether we’re reframing. We carry impact sliding glass doors and impact-rated entry units that meet the same Class A-level thinking we apply to roofs in the ember zones.

Sliding & Patio Doors

Ranch homes in West Covina almost always have a slider off the family room or dining area, and after sixty years, the rollers wear flat, the track fills with decades of San Gabriel Valley dust, and the panel binds. We replace track assemblies or the full unit, and when the rough opening has moved from slab heave, we address that before the new door goes in. A new slider in a West Covina home needs to open and close with two fingers, not a shoulder. If it doesn’t, we’re not done.

Trusted Brands We Service in West Covina

We install Andersen and Marvin windows because they’re brands you can look up, not mystery units off a van. When we quote a job in West Covina, we name the exact window line, the glass package, and the hardware, and we stock common replacement parts locally so a failed sash balance or a worn roller doesn’t leave you waiting on a warehouse in another state. If you have existing Andersen or Marvin windows that need service rather than replacement, we handle that too. Same crew, same standard, same written scope.

Common Windows & Doors Problems We See in West Covina Homes

• Clay-soil slab heave cracking window corners. The alluvial soils under West Covina expand and contract with seasonal moisture, and that movement telegraphs through stucco as diagonal cracks at window corners. Install a new window without addressing the rough opening and the sash binds within a year, then the sealant fails within one wet season.
• Single-pane aluminum frames turning rooms into ovens. West Covina sits deep in the inland San Gabriel Valley, and summer highs routinely push past 100°F, 15 to 20 degrees hotter than the coastal LA basin. Original single-pane windows let that heat pour through south-facing openings, fading flooring and cracking drywall a few feet inside the glass.
• Poorly flashed replacements rotting the subfloor. On slab-on-grade ranches, a window replacement that doesn’t get proper sill flashing lets moisture wick into the framing at the sill. By the time a homeowner notices a soft spot near the baseboard, the subfloor is already compromised. We cut out and replace rot before installing, which is why our quotes include the words “rot repair if discovered” in the scope.
• Binding interior doors from foundation movement. When the slab under a 1960s ranch heaves, interior doors start rubbing their jambs. Homeowners often chase the problem with door adjustments when the real issue is the window openings on the same wall losing their square. We look at the whole wall, not just the door.
