AfterTrusted Door Installation Nationwide
A new exterior door typically costs $900-$4,500 installed, depending on the door style, material, and how much structural work the opening needs. Most single door installations take one day from first screw to final sweep-up. Westlight Windows & Doors has handled our Door Installation in Los Angeles and across the United States since 2009, and every job starts with a written price before any work begins. Call (903) 354-7134 and a real person answers, 24/7.
We’re an independently owned and operated Kingswell location, which means we answer to our customers, not a distant corporate office. Owen Satterfield built this company on a simple idea: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. That’s the Kingswell Way, and it applies to every door we hang.
Key Takeaways
- Written pricing before any work starts, no door-step surprises
- Background-checked, uniformed technicians on every job
- 365-Day Done Right Promise: if it’s not right, we come back and fix it at no charge
- Eight manufacturer lines carried, including Therma-Tru, PGT, and CGI
- Live phone coverage 24/7, answered by a human, not a voicemail box
Front Door Replacement
Front Door Replacement is the single highest-impact upgrade most homeowners make to their house’s curb appeal and security, and most front door replacements run $1,200-$4,500 installed. A warped slab, rotted jamb, or outdated steel door that lets drafts through is a signal the opening needs more than paint. Westlight Windows & Doors replaces the entire unit, including the frame, threshold, and weatherstripping, so the new door closes square and seals tight.
Full-Frame vs. Slab-Only Replacement
When the jamb and threshold are solid, a slab-only swap saves money and keeps the existing frame. When rot or settling has thrown the frame out of square, a full-frame replacement is the only way to get a door that closes properly and seals against weather. Owen Satterfield’s crew will tell you which one your opening actually needs, not which one pads the invoice.
Material Choices That Suit Your Climate
Fiberglass doors handle hot, humid summers without warping and cold winters without sweating. Steel doors offer the most security per dollar. Wood doors look beautiful but demand regular maintenance. We’ll walk through the trade-offs in plain language, then put the recommendation in writing.
Door Replacement
Door Replacement covers any door in your home that’s failed, from a side entry that sticks every July to a back door that lets daylight show around the jamb, and individual door replacements generally span $800-$3,500 installed. The job is more than unscrewing hinges and hanging something new. It means measuring the rough opening, correcting any sag or rot, insulating around the frame, and setting the threshold so water runs away from the house. Westlight Windows & Doors pulls permits where required and passes inspections before calling the job done.
When Repair Isn’t Worth It
A cracked panel or loose hinge can often be fixed for under $300. But a door with a rotted sill, split stile, or failed seal between panes usually costs more to patch than replace. We’ll show you the damage, explain the numbers, and let you choose.
The Kingswell Guarantee on Every Replacement
Every Door Replacement job comes with a written price before work starts, a committed arrival window, a clean job site, and a written guarantee on the completed work. If the repair fails within the guarantee period, we return and correct it at no charge. That promise is handed to you in writing when the job is finished.
Sliding Glass Door Replacement
Sliding Glass Door Replacement usually costs $1,800-$5,000 installed, with the price driven by glass package, frame material, and whether the opening needs structural work. Old sliding doors are one of the biggest energy leaks in a house, with worn rollers, bent tracks, and failed weatherstripping letting conditioned air pour out year-round. Westlight Windows & Doors replaces the entire unit, including the track system, so the new door glides with one finger and locks down tight.
Impact-Rated Glass Options
For homes in hurricane zones or areas that see severe storms, we install impact-rated glass from PGT and CGI. These laminated panels resist windborne debris while still letting in the west light that gives our company its name. Owen Satterfield will explain what your local code requires and what it doesn’t.
Roller and Track Failure
The most common failure on sliding doors isn’t the glass, it’s the rollers underneath. When they wear flat, the door grinds, jumps the track, and eventually refuses to move at all. A replacement door with sealed stainless or nylon rollers fixes the root problem instead of masking it.
Storm Door Installation
Storm Door Installation adds a second line of defense against weather and insects, and a quality storm door installation typically runs $400-$1,200 installed. A storm door protects your main entry door from rain and sun, lets you open the primary door for cross-breeze without bugs coming in, and adds a layer of glass that cuts drafts in winter. Westlight Windows & Doors installs storm doors with interlocking weatherstripping and adjustable closers so the door closes softly every time.
Sizing and Fit
Storm doors come in standard widths, but few door openings are perfectly standard after years of settling. We measure the opening at three points top, middle, and bottom, then shave and shim as needed so the storm door seals against the trim without binding. A rushed install leaves gaps that defeat the whole purpose.
Hardware That Holds Up
Cheap closers fail within a year. We use pneumatic closers and reinforced corners so the door doesn’t sag on its hinges. Every storm door installation includes the 365-Day Done Right Promise: if anything isn’t right within the guarantee period, we come back at no charge.
Sliding Glass Door Installation
Sliding Glass Door Installation for a new opening, such as a patio access where none existed before, typically ranges $2,200-$6,000 installed. This is a structural job that involves cutting into a load-bearing wall, adding a header, and properly flashing the new opening so water never finds its way inside. Westlight Windows & Doors handles the full scope, including the rough framing, door installation, interior trim, and exterior sealing. We also provide Door Installation in Huntington Park and surrounding areas.
New Openings and the Header
Any opening wider than a standard single door needs a properly sized header to carry the weight above it. Undersized headers lead to sagging floors, cracked drywall, and a sliding door that binds within months. We size the header to code and engineer the opening so the door stays square.
Flashing and Water Management
The difference between a sliding door that leaks in five years and one that stays dry for thirty is the flashing. We use peel-and-stick flashing around the rough opening and a sill pan under the threshold, then seal everything in stages so water sheds away from the house.
Door Repair
Door Repair covers the everyday failures that make a door hard to use: sticking, sagging, failed locksets, rotted thresholds, and misaligned strike plates, with most repairs running $150-$600. Not every problem means replacing the door. A door that rubs at the top corner usually needs a hinge adjustment or a jamb shim, not a new slab. Westlight Windows & Doors diagnoses the actual cause, quotes the fix in writing, and completes most repairs the same day.
Diagnosing the Root Cause
Sticking doors are almost never the door itself. They’re the frame, the hinges, the foundation settling, or humidity swelling the wood. Our technicians check all four before recommending anything. That’s the difference between a door that works for ten years and one that needs another service call next season.
Locks, Latches, and Strike Plates
A deadbolt that won’t throw is a security problem, not an annoyance. We realign strike plates, replace worn latches, and adjust the jamb so the lock engages fully every time. If you’re not sure whether your door needs repair or replacement, call (903) 354-7134 and one of our technicians will help you decide.
Exterior Door Installation
Exterior Door Installation covers any door that opens to the outside of the house, from the front entry to the side garage door, with most exterior door installations running $900-$4,500 installed. Exterior doors do double duty: they’re your first line of security and your last line against weather. A properly installed exterior door sits square in a level jamb, compresses its weatherstripping evenly, and swings free without rubbing. Westlight Windows & Doors has installed exterior doors for homeowners nationwide since 2009, and every job is backed by the Kingswell Guarantee. For a deeper look at the process, see The Complete Door Installation Guide for Los Angeles Homeowners.
Sealing Against the Elements
The most important part of an exterior door installation is the part you can’t see after it’s done. We insulate the gap between the jamb and the rough opening, install a sill pan under the threshold, and seal the exterior trim so water has no path to the framing. These are the details that separate a door that lasts fifteen years from one that rots in five.
Therma-Tru and Proven Entry Systems
We carry Therma-Tru entry doors, which are engineered as complete systems rather than a slab hung in a generic frame. That means the sill, weatherstrip, and frame are all designed to work together. We also install PGT and CGI impact-rated exterior doors where storm protection matters.
French Door Installation
French Door Installation brings a wide opening of light and glass into a home, and most French door installations range $1,800-$5,500 installed. French doors are usually installed in pairs that meet in the middle, with one door active and one fixed, or both active. They’re a common choice for patios, dining rooms, and home offices. Westlight Windows & Doors installs French doors with a true astragal, real lockset alignment, and weatherstripping that makes the seam between the doors as weathertight as the sides.
Getting Two Doors to Seal as One
The hardest part of French door installation is the seam where the two doors meet. If the astragal doesn’t line up perfectly with the strike, cold air and water find their way in. We hang French doors so both panels are plumb, then adjust the astragal and lockset until the seam closes dead tight.
Inswing vs. Outswing
Traditional French doors swing inward, which works well for patios and decks. Outswing French doors seal tighter against wind-driven rain and free up floor space inside. We’ll explain which orientation fits your house and your climate, then put the plan and price in writing before any work begins.
Brands We Service
Westlight Windows & Doors works with eight manufacturer lines so the right product is matched to the job rather than the job forced to fit one brand. We install Therma-Tru entry doors regularly, which means we know their frame systems and hinge hardware inside and out. We also work extensively with PGT and CGI impact-rated doors for homes that need storm protection. ECO Window Systems gives us a strong energy-efficient glass line for sliding and French doors, and we carry ES Windows and CWS for a range of sliding glass door configurations.
Mr-Glass rounds out our line for value-focused exterior doors that still meet our installation standards. Whether you have a specific brand in mind or want us to recommend the right product for your opening, we can help. Call (903) 354-7134 and a real person will talk through your options, 24 hours a day.
Signs You Need a Pro Right Now
- Daylight around the door edges. If you can see light through the gap around a closed exterior door, the weatherstripping has failed and you’re paying to heat or cool the outdoors. A door that doesn’t seal is a door that needs professional attention before the next utility bill.
- The door sticks or drags every season. Wood and fiberglass expand and contract with humidity, but a door that only opens with a shoulder shove has a frame problem. Forcing it open will damage the hinges and the jamb over time.
- Water stains on the floor near the threshold. Water running under a door rots the subfloor and the sill plate, and the repair bill grows every time it rains. This is a flashing or threshold failure that needs a proper fix, not a bead of caulk.
- The deadbolt doesn’t fully throw. A deadbolt that only goes halfway into the strike plate leaves your home vulnerable and signals that the door or frame has shifted. This is a security concern first and a mechanical problem second.
- Fog between double-pane glass. When the seal between panes fails, moisture gets trapped inside and the glass loses its insulating value. The door still opens, but it’s no longer doing its energy job, and the fog will never clear on its own.
Our Process, Step by Step
- 1
Measure and diagnose. We measure the rough opening at multiple points, check for rot and settling, and assess the existing frame. You get a clear explanation of what you have and what it needs.
- 2
Written price before any work. We put the scope and price in writing before a single screw turns. The Kingswell Guarantee means no revised invoices and no door-step surprises. You know exactly what you’re paying and what you’re getting.
- 3
Order and schedule a committed window. We tell you when the door will arrive and when we’ll be there. We show up in the window we gave, not a vague “sometime next week.”
- 4
Remove, install, and seal. Our background-checked, uniformed technicians remove the old door, correct any framing issues, install the new door, insulate, flash, and seal. We work clean and leave protection where it should be.
- 5
Clean up and walk through. We leave the job site cleaner than we found it and walk you through the finished work. You receive your written guarantee on the spot, and the 365-Day Done Right Promise goes into effect that same day.
How Much Does Door Installation Cost?
Door installation costs vary by door type, material, and opening condition. A storm door installation runs $400-$1,200. A standard exterior door replacement runs $900-$3,500. Sliding glass door replacement runs $1,800-$5,000. French door installation runs $1,800-$5,500. A full front door replacement with a premium fiberglass or steel door and new frame typically lands between $1,200 and $4,500.
Several factors move the price. Structural work around the opening adds cost. Glass packages make a difference, with impact-rated glass from PGT or CGI priced above standard insulated glass. Hardware quality matters too, and a high-security lockset adds line items you should see and approve before work starts.
The best way to avoid overpaying is to get a written price from a contractor who guarantees it. Our free estimate includes the full scope: door, frame, hardware, flashing, insulation, trim, and cleanup. You’ll see every line item before you commit to anything. Call (903) 354-7134 to schedule your free estimate, and you’ll have your written price before any work begins.

Frequently Asked Questions About Door Installation
Door installation is the process of fitting a new door into an opening so it hangs square, swings freely, seals tightly, and locks securely. It includes measuring the rough opening, correcting any framing or rot, installing the door and hardware, insulating, and weather-sealing. At Westlight Windows & Doors, every installation includes a written price and a written guarantee before any work begins.
Most single door installations take one day from start to finish, including removal, any light framing correction, installation, sealing, and cleanup. Sliding glass door and French door installations may take a day and a half when the opening needs structural work or when we’re creating a new opening from scratch. You’ll receive a committed arrival window and a realistic timeline before the job starts.
Most door installations range from $400 for a storm door to $5,500 for a premium French door or sliding glass door, depending on material, glass package, and structural work. You’ll receive a written line-item quote before any work begins, so the final price matches the price you approved. Call (903) 354-7134 for a free estimate and exact numbers for your project.

Clear a path from the entrance to the work area and move furniture, rugs, and wall hangings at least six feet from the door. If you have pets, plan to keep them in a separate room during the installation. Our technicians bring drop cloths and leave the site cleaner than they found it, but a cleared work area helps the job go smoothly. We’ll walk you through any other preparation when you schedule.
