AfterFast, Reliable Windows & Doors Across Covina
Window and door replacement in Covina costs more than just the unit itself, because most homes here were built between 1945 and 1975, and the framing behind those original single-pane aluminum windows has spent decades fighting San Gabriel Valley clay soil. A straightforward dual-pane swap in Covina typically runs $4,500-$15,000, while full impact window installation lands between $8,000 and $25,000. We’re Barrett & Sons Construction, and we’ve been opening up Covina walls long enough to know what’s behind them before we quote the job. Call (877) 610-1318 for a free estimate.
Why Barrett & Sons Construction Is Covina’s Preferred Windows & Doors Company
Tom Barrett founded this company in 1998, and his sons run the crews that work Covina’s 91722, 91723, and 91724 neighborhoods every week. We’re not dispatching strangers from a call center. When you call, a live person answers, and if something’s wrong after the job, Tom’s name is on the contract, not a franchise logo. Our 90-Day Done Right Promise is written on every window and door job: if it’s not done right, one call brings us back. No fine print, no runaround.
Covina homeowners have seen the national outfit playbook before: a low phone quote, then a “revised” invoice once the wall is open. We do the opposite. Every scope, every allowance, every price change arrives as a written change order before work proceeds. That’s not a slogan; it’s how we’ve kept our reputation in Covina for over 29 years. Windows & Doors is one of our core trades, and we treat every Covina home like it’s on our own street.
Our Windows & Doors Services in Covina
Window Replacement
Most Covina ranch homes still wear their original single-pane aluminum frames from the Eisenhower and Nixon administrations. Those windows were never energy-efficient, and after 50-plus years of 100°F summers and seasonal clay movement, the frames twist and the sashes bind. We replace them with dual-pane units that actually close square and seal tight. Every replacement starts with an inspection of the rough-in framing, because Covina’s soil has usually moved things around.
Impact Windows & Doors
Impact-rated windows in Covina run $8,000-$25,000 depending on how many openings and the condition of the existing headers. These aren’t just for coastal hurricane zones. Covina’s inland heat cycles stress exterior caulk and stucco, and impact glass adds structural shear strength that older frames simply don’t have. For Covina homeowners planning to stay in the house another 20 years, this is the highest-value upgrade we install.
Sliding & Patio Doors
Original aluminum sliders on 1960s Covina homes seize in twisted frames as the slab beneath them shifts. We replace them with modern dual-pane sliders or French doors, re-squaring the opening first and installing load-bearing headers where the original framing has drifted out of level. If you’re thinking about converting a garage to an ADU, this is the moment to address the patio door: the permit trigger we’ll cover below applies.
Door Installation
Front doors and exterior doors on Covina’s stucco ranches often hide dry rot along the rough-in framing, especially on the west-facing walls that take the full afternoon heat. We don’t just hang a new door and call it done. We open the rough-in, confirm the header is bearing evenly, replace any damaged framing, then set the door with proper flashing and backer rod so water from the next wet season stays outside.

We install materials you can look up, not mystery brands off a van. For Covina window jobs we regularly work with Andersen and Marvin units, and for door hardware and waterproofing we rely on Schluter and GAF flashing systems. Because our crews work Covina weekly, we can get parts fast when something needs reordering, and we stand behind every brand we install under the same 90-Day Done Right Promise.
Common Windows & Doors Problems We See in Covina Homes
- Clay soil settlement shifts frames out of square. The montmorillonite clay under Covina’s slab-on-grade homes expands in winter and contracts in summer, and over 50 years that cycle racks window and door openings. Binding sashes and stress cracks at mitered corners in original aluminum frames are the telltale signs. We correct the framing before installing new units.
- Summer heat destroys exterior caulk and stucco. Covina regularly tops 100°F in July and August, 15-20 degrees hotter than the coast. That heat bakes the original caulk around window perimeters until it cracks, then winter rains find the gaps. By the time we open a wall, the damage is usually deeper than the caulk line.
- Weep holes clogged and abandoned. Original galvanized weep holes on 1960s Covina windows corrode and fill with debris over the decades. When they stop draining, water pools inside the frame and rots the wood buck behind the stucco. A simple window swap often uncovers this because the old unit hid it.
- Unpermitted replacements from prior owners. We see a lot of Covina homes where someone replaced windows in the 1990s without pulling permits. Those jobs typically lack proper shear and hold-down connections. When we open the wall for a new window, the permit triggers upgrades to rough-in framing and waterproofing that were never compliant. We handle that paperwork and the inspection, and we tell you about it before the hammer swings.
Pricing for Windows & Doors in Covina, CA
Covina’s window and door pricing reflects what’s actually behind the stucco. Here are the ranges we quote most often:
| Service | Covina Price Range |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
The spread depends on how many openings, whether the framing needs header reinforcement, and whether your existing rough-in is square or has shifted with the clay. That’s why we inspect before we quote. If you already have a written estimate from another company, bring it in: we offer a free second opinion, and there’s no trip charge inside the county.

FAQs - Windows & Doors in Covina
Because Covina’s 91722 east-side neighborhoods sit on expansive montmorillonite clay, and the seasonal expansion and contraction cycle has been shifting those 1960s slab foundations for five decades. Original headers that once bore evenly are now carrying load off-center, and when we remove the old window, the rough-in framing is often out of square and under-supported. We install a new engineered header and re-square the opening before the new unit goes in. Call (877) 610-1318 and we’ll tell you if your job needs this after the inspection.
Yes. Covina requires permits for window replacements when the opening size changes or when structural framing is modified, and that applies to most swaps on older homes where the rough-in needs re-squaring. We pull permits on every eligible job and we schedule the inspections. The permit inspector works for you, not for us, which is exactly why we want him on the job. A permitted replacement also protects your resale value if you sell the Covina house later.
You get a written change order before any additional work happens. We don’t touch the framing until you’ve seen the scope, the allowance, and the price in writing. On a 1963 single-story ranch in Covina’s 91722, we replaced a set of failing aluminum sliders that had seized in twisted frames, and after removing the stucco our crews found the rough-in had moved enough that the original header was no longer bearing evenly. We installed a new engineered header, re-squared the opening, then set a modern dual-pane slider with integrated flashing and backer rod, all documented for inspection sign-off before closing the wall. That’s the standard, not the exception.
Yes, and in fact they handle it better than the original single-pane aluminum they replace. Impact-rated dual-pane units use laminated glass and reinforced frames that resist heat-driven frame distortion and seal failure. Covina’s inland climate puts more thermal stress on window perimeters than coastal LA, and impact windows are built to handle that cycle without cracking caulk lines or warping sashes. They also add shear strength to the wall, which matters on Covina homes with clay-shifted framing.
Because the permit for the ADU will trigger code upgrades on any opening adjacent to the new living space. If your garage has an original aluminum slider from the 1960s, it lacks the shear and hold-down connections current code requires, and the inspector will flag it. Replacing the slider before or during the ADU conversion means one permit, one inspection, one set of change orders, instead of two separate jobs. It also gives the new ADU a properly sealed, code-compliant exterior opening from day one. Call (877) 610-1318 to talk through the sequence.
