Trusted Door Replacement for West Covina Homeowners
Door replacement in West Covina typically runs $900 to $4,600 depending on the door type, material, and whether you’re upgrading to an impact-rated or decorative glass unit. Most front and patio door installations wrap up in one day, but full frame replacements can take two. Juniper Windows West Covina, led by Sean Mackey, has been installing exterior and interior doors in West Covina since 2001, and we show up with a written price, a live arrival time, and a 365-day warranty on parts and labor, the same standard we bring to our Door Replacement in Glendora. Call (350) 305-4609 to schedule your free estimate.
Door Frame Repair
Door Frame Repair in West Covina addresses rotted, warped, or misaligned frames that keep a door from latching, sealing, or closing properly. You need it when the frame is soft to the touch, separated at the corners, or visibly cracked around the hinges, and symptoms often show up first as drafts, squeaks, or a strike plate that no longer catches. Juniper Windows West Covina repairs or replaces door frames in the $350 to $1,200 range depending on whether we can splice in a section or need to pull the full jamb. In West Covina’s dry summers and wet winters, wood frames expand and contract enough to displace the door, and minor fixes now prevent a full replacement later.
Frame Rot and Moisture Damage
West Covina’s Santa Ana winds drive rain sideways, and bottom corners of exterior door frames absorb most of that moisture. We cut out the rotted section, treat the remaining wood, and install a primed filler block, then reseal the perimeter. The repair is invisible once the door is rehung.
Strike Plate and Hinge Reset
If the door no longer closes because the frame has shifted, the frame often is not the problem at all, it is the jamb fasteners. We reset the jamb, re-shim the hinges, and move the strike plate so the latch catches cleanly on the first try. This runs on the low end of the price range and usually takes under two hours.
Interior Door Replacement
Interior Door Replacement in West Covina swaps old hollow-core or damaged doors for solid-core, panel, barn, or French doors that change the feel and sound profile of a room. You need it when a door is cracked, delaminated, or too thin to block noise between bedrooms and living spaces. Juniper Windows West Covina installs interior doors for $175 to $700 per opening, including hardware and a written price before we start. We hang pre-hung units or re-slab existing frames depending on what the jamb can handle, and the 365-Day Done Right Promise covers the installation.
Solid-Core Upgrades
West Covina’s older ranch homes still have hollow-core slabs that pass sound through the house. A solid-core upgrade makes a real difference, it cuts noise between hallways and bedrooms, and feels weighted and substantial when it closes.
Barn and French Door Conversions
When the opening width allows, a barn door frees up floor and wall space in smaller rooms. French doors add light without a structural change, but they need a level floor and properly installed track or astragal to avoid rattling.
Interior Door Installation
Interior Door Installation in West Covina covers the full job, measuring, selecting the right slab or pre-hung unit, fitting hinges, routing hardware, and getting the reveal consistent around the frame. You need it whenever a new door is going into a new opening or replacing a door too worn to save. Juniper Windows West Covina charges $200 to $800 for interior door installation, including trim work and sealing, with a line-item quote before anything starts. We account for West Covina’s older, out-of-square walls so the door does not drag or swing open on its own.
Pre-Hung vs. Re-Slab
If the existing frame is square and solid, re-slabbing saves money and time. If the frame has moved or the rough opening is irregular, a pre-hung unit is the right call, and we carry both options for jobs across West Covina.
Hardware and Hinge Precision
A door that scrapes the floor or clicks against the jamb is nearly always a hinge mortise that was routed too shallow. We set hinge depth with a jig, not by eye, and test the swing three times before calling the room finished.
Door Installers
Door Installers at Juniper Windows West Covina handle exterior doors, patio sliders, interior slabs, and full frame replacements, and every installer is background-checked and uniformed. You need a pro when a door is more than a cosmetic swap: when the opening is irregular, the threshold has sunk, or the door in question weighs more than a standard interior unit. Door installer labor in West Covina runs $300 to $1,200 per opening depending on the door type and frame condition. Our team works with Therma-Tru and Mr-Glass products most often, and the crew leaves the job site swept and the old door hauled away.
Exterior Door Specialists
Exterior doors carry more load than interior doors, and they have to keep water out, not just close. We set thresholds on a slope, flash the pan, and run sealant along the bottom rail; when a front or rear door fails, the fix is rarely the door itself, it is what supports it.
Patio and Slider Installers
Sliders take a different skill set than a swing door, especially on concrete slabs that have settled over the years. We level the track, set the rollers, and adjust the interlock so the panel locks without binding, and a Mr-Glass or Therma-Tru slider we install gets tested for smooth travel with both hands on the handle.
Door Contractors
Door Contractors in West Covina are the generalists among us, but Juniper Windows West Covina is not a generalist shop; doors and windows are all we install, and Sean Mackey has kept that focus since 2001. You need a door contractor when the project touches framing, waterproofing, or security hardware, whether that means a sidelight replacement, a wider rough opening, or a new entry system. Door contractor projects in West Covina run $500 to $4,600, and the biggest variables are whether the opening needs reframing and whether the door includes decorative or impact-rated glass. Every contract gets a written price and a photo-documented job file.
Full Entry System Replacements
A front door is not just a door; it is a system of jamb, threshold, weatherstripping, hinges, and hardware. We quote the complete entry system, not a door slab that gets set into a 40-year-old frame and expected to perform.
What the 365-Day Done Right Promise Covers
If anything about the installation fails in the first year, parts and labor are covered in writing. That includes alignment, sealing, hardware and latch operation, and the door’s swing, anywhere in the West Covina service area.
Brands We Service
We install and service Therma-Tru doors, the most trusted fiberglass entry door line in the country. Therma-Tru’s fiberglass skin does not dent, warp, or rot the way wood does, and we order their units pre-finished so the color sits in the material rather than on top of it. We regularly install Therma-Tru’s Classic-Craft and Pulse lines in West Covina, and our crew knows which door bottom and weatherstripping profiles spec correctly with each series.
Mr-Glass and PGT supply the sliding patio and impact-rated lines we install throughout the San Gabriel Valley, including Azusa Door Replacement projects. PGT impact-rated doors, built to resist wind-borne debris without shattering, are increasingly common in West Covina’s higher elevation pockets where Santa Ana wind gusts hit hardest. We also work with ViewLux and several other quality lines because the right door is never a compromise. Whether you have one of these brands or something else, we can source, install, and warranty the replacement.
Signs You Need a Pro Right Now
- The door sticks, drags, or won’t latch. This means the door or the frame has moved, and forcing it worsens the problem. A door that will not latch is also a door that will not seal, which raises your cooling bill all summer in West Covina.
- You can see daylight around the frame. That gap is not just cosmetic. It is an entry point for hot air, dust, and pests, and it signals a failed seal or a sagging threshold that needs immediate attention.
- The frame is soft when you press on it. Soft wood is rot. It will only spread, and once it reaches the subfloor or the wall studs, the repair cost jumps beyond what a simple door replacement would have been.
- The glass is cracked, foggy, or shaking in the frame. Dual-pane door glass that fogs has lost its seal. Impact or tempered glass that cracks needs to be swapped before the pane fails completely.
- The door is original to a pre-1990 West Covina house. Older doors are rarely energy-efficient and often lack modern multi-point locking. Replacing them now beats finding water damage or a failed lock at 10 p.m. on a Friday.
Our Process, Step by Step
- 1
Call or book online and speak with a live person. You reach us at (350) 305-4609, and a person answers, 24/7. We schedule a time, and you get a live arrival time via The Relay Standard, no four-hour windows.
- 2
On-site measurement and door condition review. Our installer measures the rough opening in three places, checks the floor for level, examines the existing frame for rot, and takes note of exposure, sun, wind, and security. This is the diagnostic step that tells us whether you need a slab, a pre-hung unit, or frame repair.
- 3
Written, line-item quote. You get a price in writing that includes the door, the labor, the hardware, the haul-away, and the tax. The number on that quote is the number on the invoice; we do not adjust at the door.
- 4
Installation, documented step by step. The crew arrives at the scheduled time, preps the opening, installs and levels the door or frame, sets the lockset, seals and tests. You get before-and-after photos of the job site through the Relay Visibility Guarantee.
- 5
Digital invoice and 365-Day Done Right Promise. You pay from a link, and your warranty is in writing for a full year, parts and labor. If anything is not done right, we come back and make it right, no charge, no argument.
How Much Does Door Replacement Cost in West Covina?
A typical front door replacement in West Covina runs $1,200 to $3,800 depending on the material, glass package, and whether the frame gets replaced with the slab. Interior door replacement is lower, usually $175 to $700 per door, and a full patio slider runs $1,500 to $4,600. The main price drivers are the door material (solid wood is more than fiberglass, which is more than hollow core), glass type (impact-rated and decorative glass add cost), hardware grade, and whether the rough opening needs reframing. Labor runs $300 to $1,200 per opening in West Covina. The best way to avoid overpaying is to get a written line-item quote that separates the door cost from the labor, and to confirm the warranty covers parts and labor for 365 days, not just the door. Our free estimate includes the measurement, the condition check, and the full price, no obligation. Call (350) 305-4609 to book one.
