We will talk you out of it
If two windows have failed and eighteen are fine, we quote two. A company that opens every conversation at whole-home replacement is telling you about its business model, not about your windows.

Your McKinney Window Installers
Meet Don and Blake. Your McKinney window installers.
Don and Blake got into windows by climbing McKinney roofs. Hail season after hail season, they were up documenting impact damage — and kept noticing the same thing on the way down the ladder: the house that had a hail-damaged roof almost always had hail-damaged windows too.
Cracked panes. Seals bruised by impact that would fog out a year later. Dented cladding and shredded screens on the same elevation that took the worst of the storm. Almost none of it was in the claim, for a simple reason — the adjuster was on the roof, so the roof got scoped and the windows never did.
Owners measure, owners install
No commissioned salesperson handing your numbers to a crew you have not met. Same two people from the estimate through the final walkthrough.
Two warranties, both in writing
The manufacturer covers the glass. We cover the labour, separately and on paper. Only one of those depends on the company still being here — ours, and we are.
McKinney Window Services
What we do on McKinney windows.
Four jobs. A window company in McKinney, Texas should tell you honestly which one you actually need before quoting any of them — so that is what we do.
Full-home window replacement
Whole-house and multi-window replacement for McKinney homes that have reached the end of their original glass. Custom-measured to your openings, ordered after you approve the written scope, and installed by the owners.
Common on 1990s and 2000s builds across Stonebridge Ranch and the older Eldorado corridor, where builder-grade units are hitting the age where seals go one after another.
Foggy glass & single-window repair
Fog between the panes is a failed insulated glass unit, not a failed window. Where the frame and sash are sound we replace the glass unit alone, which is normally the cheaper outcome.
Also broken panes, failed hardware, sashes that will not latch, and units damaged by impact. One window is a job we will actually take.
Patio, entry & sliding doors
Sliders, French doors and entry doors are part of the same weather envelope and fail for the same reasons as the windows around them.
A slider that has gone hard to move is usually a track, roller or racking problem. We diagnose that before quoting a replacement door you may not need.
Hail & storm damage window claims
Window damage is routinely left off McKinney hail claims because the adjuster is scoping the roof. Cracked glass, dented cladding, torn screens and impact-bruised seals are all documentable.
We photograph windows at the same time we photograph the roof and meet the adjuster on site, so the whole envelope is in one claim instead of two.

Repair or Replace
We will help you determine which windows need replacing
Fog between the panes means one thing — the insulated glass unit’s seal has failed and the argon fill is gone. What it does not automatically mean is that you need a new window.
Replace the glass unit when…
- The frame is straight, sound, and free of rot or warping
- The sash still closes square and the weatherstrip seals
- Hardware — locks, balances, hinges — still operates properly
- One or two units have fogged, not a whole elevation
- The unit is a standard size a fabricator can match
This is the cheaper outcome and it is the one most McKinney homeowners are not offered, because it is a smaller ticket for the contractor.
Replace the whole window when…
- The frame is warped, rotted, or racked out of square
- The sash no longer seals evenly along its full length
- Hardware has failed and parts are no longer manufactured
- Several units on the same elevation have fogged together
- The window is single-pane, or has no Low-E coating at all
When four windows on the west elevation fog in the same eighteen months, that is the elevation telling you its glass reached end of life together.
Why Windows Fail Here
What actually kills a window in McKinney.
Windows rarely fail because the glass “wore out.” They fail at the seams, in an order that is fairly predictable once you have pulled enough of them out of North Texas houses. Here is what we inspect, and why each one matters in this specific climate.
Insulated glass unit
Two panes with an inert gas fill and a perimeter seal. A 40-degree overnight temperature swing expands and contracts that assembly every single day. Thermal cycling is what eventually breaks the seal — and once it breaks, the gas is gone and the window is just two sheets of glass with condensation between them.
West and south elevations
North Texas afternoon sun is brutal and it is not evenly distributed around your house. West-facing units take dramatically more UV and heat load than north-facing ones, which is why they fail years earlier and why they drive the most cooling cost. If you are replacing in phases, this is the elevation to start with.
Hail and wind-driven debris
Hail cracks glass outright, which is obvious. What is less obvious is a bruised seal that survives the storm and fogs out a year and a half later — long after the Texas one-year claim window has closed. That delay is exactly why window damage needs documenting on the day, not when it becomes visible.
Expansive clay soil
Collin County clay moves enough between wet and dry seasons to rack a rough opening out of square. When that happens the sash no longer meets the frame evenly along its full length, so it leaks air on one corner regardless of how good the window is. Replacing the unit without correcting the opening just repeats the problem.
Flashing and weep holes
Windows are designed to let a small amount of water in and drain it back out through weep holes at the sill. Blocked weeps and bad head flashing are behind a large share of the leaks blamed on “bad windows.” We check the drainage path on every unit, because a perfect window installed over bad flashing still leaks.
Measurement and squaring
A custom window is built to numbers written down at your house. Measure wrong and you get a unit that has to be shimmed into fitting, which loads the frame and starts the failure clock early. This is the least glamorous item on this list and the one that most determines whether your new windows last.
Reading a Window Quote
What To Look For In a Window Quote
Most window company quotes list a brand and a price. Neither of those tells you how the window will actually perform in a McKinney, Texas August.
You get two warranties. The manufacturer’s glass warranty and the installer’s labour warranty are separate documents covering separate failures. A seal failure is the manufacturer’s. A leak at the flashing is the installer’s. Ask for both in writing, and notice which one depends on the company still existing in eight years.
| Spec | What it measures | Why it matters here |
|---|---|---|
| U-factor | Heat transfer through the whole window. Lower is better. | Matters most on winter nights. Useful, but in Texas it is the second-most important number, not the first. |
| SHGC Solar Heat Gain Coefficient | How much solar heat passes through. Lower is better. | This is the one that matters most in McKinney. It governs how much of that west-facing afternoon sun turns into cooling load. |
| Low-E coating | A microscopically thin coating that reflects infrared. | Different coatings are tuned for different climates. A window optimised for a northern winter is the wrong window for a Collin County summer. |
| Argon fill | Inert gas between panes instead of air. | Improves insulation — and it is the thing that escapes when a seal fails, which is why a fogged unit also stops performing. |
Where We Work in McKinney
Common issues we see in McKinney neighborhoods.
McKinney, Texas is not one housing stock. A 1900s home downtown, a 1990s Stonebridge Ranch build and a 2020 Trinity Falls house have almost nothing in common at the window, and a window company that quotes them the same way is not really looking.
Historic Downtown McKinney
The one part of town where the paperwork outweighs the product decision. Homes in the “H” Historic Overlay District need a Certificate of Appropriateness before a permit issues, and window replacement is named in the city’s own packet. Plan the review calendar first, order glass second.
Stonebridge Ranch
One of McKinney’s largest master-planned communities, and a big share of it went up in a tight window in the 1990s and 2000s. That means original builder-grade glass reaching end of seal life across whole streets at once. Architectural review governs frame colour and grille pattern.
Craig Ranch
Newer construction with a mix of single-family, patio homes and higher-density product. Larger glass openings and more contemporary frame profiles, which makes matching the existing exterior appearance the constraint when replacing an elevation at a time.
Adriatica Village
Mediterranean-styled architecture where window shape and proportion are doing real work visually. Replacement here is as much an appearance decision as a performance one, and the architectural committee cares about both.
Eldorado & Virginia Parkway corridor
Established McKinney neighborhoods along the older east-west corridors, with a wide spread of build dates. Mature trees mean more debris and more shade variance — north elevations can be fine while the west side has failed entirely.
Trinity Falls & north McKinney
Newer homes where whole-house replacement is rarely the question. What we see instead is single-unit failures — an impact crack, a seal that went early, hardware that stopped latching — and warranty-adjacent conversations about whether it should have failed at all.
HOA note: most McKinney master-planned communities review exterior changes through an architectural committee, and on windows it is almost always frame colour and grille pattern that get flagged. We prepare and submit the packet the same way we do for roofing colour approvals — so the project is not sitting idle waiting on a committee after the glass has already been ordered. If you are in the Historic Overlay District, that review is a Certificate of Appropriateness and it is a legal requirement, not an HOA preference.
How It Works
How the window estimating process works.
No pressure and no same-day-discount theatre — the two things that make people dread calling a window company. If your windows do not need replacing yet, we say so and leave.
You call or book
Call (214) 325-7014 or submit the form. Most McKinney estimates are scheduled within 24 to 48 hours.
We measure and photograph
Every unit opened, checked for square, weep holes inspected, each failure photographed. HOA status confirmed for your address.
You get a written scope
Which windows need glass, which need replacing, which are fine. Itemised, in writing, with the specs listed — never a verbal number.
Approvals, then order
HOA packet submitted and approved first. Glass is ordered after that, never before — so nothing sits in a warehouse waiting on a committee.
FAQ
McKinney windows — frequently asked questions.
The questions we get on almost every McKinney window estimate. Tap any question to expand.
How do I choose a window company in McKinney, TX?
Check three things. First, a verifiable local street address — Texas does not license window contractors, so a real address you can drive to is the cheapest screening available. Second, ask who measures: measurement errors are the single most common cause of a failed window install, and the person measuring should be the person accountable for the result. Third, get the labour warranty in writing separately from the manufacturer’s glass warranty — they are two different things and only one of them depends on the company still existing. Fireman’s Roofing is at 7101 S Custer Rd in McKinney, and the owners run the measurement and the install.
Do I need a permit to replace windows in McKinney, TX?
It depends on scope. Like-for-like replacement in an existing opening is treated differently from work that changes the opening size or alters structure, which involves a header and does require review. The City of McKinney’s Building Inspections division is the authority on your specific job. Separately, if your home is in the Historic Overlay District, a Certificate of Appropriateness is required before any permit can be issued. We confirm both before we order glass.
Do I need a Certificate of Appropriateness to replace windows in McKinney’s historic district?
Yes. The City of McKinney’s Certificate of Appropriateness application packet lists replacing windows explicitly among the changes subject to city regulation, and states that a Certificate of Appropriateness is required before a permit can be issued for properties in the historic districts. Many applications are approved at staff level when the work conforms to the Secretary of the Interior’s Standards. If yours goes to the Historic Preservation Advisory Board, the completed application must be received at least two weeks before the scheduled board meeting. Staff aims to return initial comments within 10 business days.
Can foggy windows be repaired, or do they need replacing?
Fog between the panes means the insulated glass unit’s seal has failed and the inert gas fill is gone. The frame is usually fine. If the frame and sashes are sound and the unit is a standard size, replacing just the glass unit is often the cheaper fix. If the frame is warped, the sash no longer seals, hardware has failed, or several units in the same elevation have fogged at once, replacement is normally the better economics. We tell you which situation you are in before quoting either one.
Does homeowners insurance cover hail-damaged windows in McKinney?
Often, yes, when hail or wind-driven debris is the cause of loss. The problem is that window damage is regularly left out of the scope on hail claims because the adjuster is focused on the roof. Cracked glass, dented cladding, damaged screens, and impact-broken seals are all documentable. Texas gives homeowners one year from the date of loss to file. We document windows at the same time we document the roof, so nothing gets left off the claim.
How long does window replacement take in McKinney?
The install itself is usually one to two days for a typical McKinney home. The longer part is manufacturing: custom-sized units are built to your measurements after you approve the order, which is normally several weeks. Historic Overlay District homes add the Certificate of Appropriateness review before anything can be ordered. We give you the real calendar at the estimate rather than an install date we cannot hold.
What makes windows fail in the North Texas climate?
Four things, in roughly this order. Thermal cycling — a 40-degree overnight swing expands and contracts the glass unit daily until the seal gives out. UV load on west and south elevations, which degrades seals and vinyl faster on those sides of the house than on the north. Hail, which cracks glass outright and bruises seals invisibly. And expansive clay soil, which moves the structure enough to rack an opening out of square so the sash no longer seals evenly.
Which windows should I replace first if I can’t do the whole house?
Start with the west-facing elevation. It takes the hardest afternoon sun in North Texas, so those units fail first and they drive the most cooling load. After that, prioritise any window with a failed seal, any that no longer latches or seals shut, and any with visible frame damage. Doing an elevation at a time is a legitimate approach — matching the exterior appearance is the constraint to plan around.
Do you replace patio and entry doors too?
Yes. Patio sliders, French doors, and entry doors are part of the same weather envelope and frequently fail for the same reasons as the windows around them. A slider that has become hard to move is usually a track, roller, or racking problem rather than a door problem, and it is worth diagnosing before replacing.
What should I look for on a window quote?
Four numbers and two warranties. U-factor, which measures heat transfer — lower is better. Solar Heat Gain Coefficient, which measures how much solar heat gets through — lower matters more in Texas than almost anywhere. Whether the glass has a Low-E coating. Whether the cavity is argon-filled. Then the manufacturer’s glass warranty and, separately and in writing, the installer’s labour warranty. A quote that lists a brand name and a price but none of these four numbers is not a quote you can compare against another one.
Are you licensed and insured to install windows in McKinney?
We carry general liability and workers’ compensation and are BBB A-rated. Texas does not issue a state licence for window contractors — the same is true for roofing — so insurance certificates and a verifiable local address are what there actually is to check. We hand every McKinney homeowner certificates before work starts, unprompted.
Do you handle HOA approval for window replacement?
Yes. Many McKinney master-planned communities, including Stonebridge Ranch and Craig Ranch, review exterior changes through an architectural committee, and frame colour and grille pattern are the details that typically get flagged. We prepare and submit the packet the same way we do for roofing colour approvals so the project is not waiting on a committee vote after the glass has already been ordered.
Why is a roofing company doing windows?
Because it is the same building envelope and, on storm claims, the same conversation. Fireman’s Roofing & General Contractor has worked McKinney exteriors since 2020, and the most common thing we found on hail inspections was window damage nobody had documented. Windows are a deliberate extension of the general contracting side of the business, run by the same two owners out of the same McKinney address.
Is the window estimate really free?
Yes — free, with no obligation. We measure, photograph the condition of each unit, and give you a written itemised scope. If your windows do not need replacing yet, we say so and leave. If only two of them do, we quote two.
