Window Replacement in Provo & Utah County
Windows That Fit the Opening, Not the Catalogue
Utah is hard on windows. Afternoon sun at four thousand feet works on the seals, and a valley that can swing forty degrees between morning and evening makes every frame in the wall expand and contract, over and over, for years. Eventually a seal lets go, the glass fogs from the inside, and the window you cannot clean is the one telling you it is done.
Phoenix Exteriors installs Alpine vinyl windows — the 7000 Series, the 8000 Series, and the Montrose line. Every unit is built to the measurement of your opening rather than shimmed into a stock size, because a window that has to be packed out to fit is a window that will leak air somewhere.
We do both insert and full-frame installation, and we decide which after we have looked at the opening — not before. That distinction is most of what separates a window job that lasts from one that buries a problem behind new vinyl.
Insert or Full-Frame
The right answer depends on the condition of what is already in the wall. Here is how the two differ, so you can tell whether the recommendation you are given makes sense.
Insert Replacement
The new window fits inside your existing frame. Interior and exterior trim stay where they are, so there is no patching, painting, or disturbed drywall.
- Best when: the existing frame is solid and square.
- Upside: faster, cheaper, and far less disruptive.
- Trade-off: slightly smaller glass area, since the new frame sits inside the old one.
Full-Frame Replacement
Everything comes out to the rough opening. We inspect the framing and sill, address any rot, flash the opening properly, and set a new unit into a clean opening.
- Best when: there is rot, racking, or a history of leaks.
- Upside: problems get fixed rather than covered, and you keep full glass area.
- Trade-off: costs more, takes longer, and trim needs finishing.
An insert over a rotted frame looks finished on day one and fails quietly for years. If we find that, we will tell you — even though it is the more expensive conversation to have.
The Alpine Lines We Carry
Three vinyl lines at different price points. We bring samples of all three to the estimate so the differences are something you can see and handle rather than read off a brochure.
Alpine 7000 Series
One of the three Alpine vinyl lines we install. Welded vinyl frame with an insulated glass unit, built to the exact size of your opening rather than trimmed down from a stock size.
Alpine 8000 Series
A step across the Alpine lineup from the 7000. We will show you exactly what changes between the two — frame profile, glass package, and warranty — so the price difference is something you can see rather than take on faith.
Alpine Montrose
The third Alpine line we carry. Like the others, we bring a physical sample to the estimate so you can handle the frame, work the lock, and compare it against the rest before deciding.
Every Opening in the House
Whole-home replacements, a single problem window, or a fogged pane that does not need a new unit at all.
Double-Hung & Single-Hung
The most common replacement window in Utah County. Double-hung sashes both tilt in, which makes cleaning a second-story window something you can do from inside the house.
Sliders
Horizontal sliding windows for wide openings and basements. Fewer moving parts than a hung window and easy to operate over a counter or sink where reaching a crank is awkward.
Casement & Awning
Crank-out windows that seal against the frame as they close, so they tend to be the tightest style against wind. Awning units shed water while open, which is useful on a sheltered wall.
Picture & Fixed
Non-opening units for view walls and stairwells. No moving hardware means more glass and less frame, and nothing to wear out.
Bay & Bow
Projecting assemblies that add floor depth and light to a room. These need the head and seat framed and flashed correctly, which is where most bay window leaks start.
Egress & Basement
Basement bedroom windows sized to meet egress requirements. If you are finishing a basement, this is a code question before it is a window question, and we will tell you where you stand.
Glass Packages
Low-E coatings and argon fill on insulated units, which is what does the actual work of keeping heat out in July and in during January. We will walk through the options on each Alpine line.
Glass Unit Replacement
For fogged windows where the frame and sash are still sound, replacing just the failed insulated glass unit costs considerably less than a whole new window.
Storm & Impact Damage
Broken glass, damaged frames, and windows taken out by hail or debris. If it is going through insurance, we work with adjusters every week and can help document it.
When Windows Are Worth Replacing
Fogging Between the Panes
Condensation inside the glass means the seal has failed and the insulating gas is gone. You cannot clean it and it will not clear. This is the clearest signal a window is finished — or at least that the glass unit is.
Drafts You Can Feel
A noticeable cold edge near a closed window in January usually means the sash no longer seals, the frame has racked, or the unit was never packed and sealed properly when it went in.
Windows That Fight You
Sashes that stick, will not stay up, or need a shoulder to close. Beyond the daily annoyance, a window that is painful to open is a window that stays shut in a fire.
Utah Sun on West Walls
High-altitude afternoon sun is hard on seals and hard on the room behind the glass. Modern Low-E coatings cut the heat gain without turning the window into a mirror.
Road and Neighborhood Noise
Insulated glass and a frame that actually seals make a real difference on a busy street. It is rarely the reason someone calls, and often the change they notice first.
Selling the House
Fogged and painted-shut windows read as deferred maintenance to a buyer, and they price it that way. New windows are visible from the curb and from every room inside.
Our Window Replacement Process
- 01
Free On-Site Estimate
We measure every opening, check the frames and sills for rot or movement, and talk through which openings genuinely need replacing. You get a written, itemized estimate. No high-pressure close — take the time you need.
- 02
Line & Style Selection
Samples of the 7000 Series, 8000 Series, and Montrose come to the house so you can compare them in your own light, against your own trim. We go through styles, glass packages, and grid options at the same time.
- 03
Insert or Full-Frame Call
Based on what we found at the estimate, we recommend insert or full-frame for each opening and explain why. Sometimes it is different answers in different walls of the same house.
- 04
Custom Manufacture
Units are built to your measurements. This is the wait in the project — nothing is happening at the house while the order is in production, and we will tell you what to expect.
- 05
Installation
Old units out, openings checked and flashed, new windows set level, square, and properly insulated and sealed at the perimeter. Full-frame openings get any rot addressed before the new unit goes anywhere near them.
- 06
Cleanup & Walk-Through
Old windows and packaging hauled away, glass swept, and a walk-through with you at every opening. We open and close each one with you so nothing gets discovered after we have left.
Window FAQ
How much does window replacement cost in Utah?
- Vinyl replacement windows in Utah generally run $450 to $1,100 per window installed, depending on size, style, and glass package. Full-frame installation typically adds $150 to $400 per opening over an insert. A whole-home project of 10 to 15 windows commonly lands between $7,000 and $18,000. Those are market ranges, not a price list — we measure every opening and give you a free, written, itemized estimate before you commit to anything.
What brand of windows do you install?
- We install Alpine vinyl windows — the 7000 Series, the 8000 Series, and the Montrose line. We bring samples of all three to the estimate so you can compare the frame, the glass package, and the warranty side by side, in your own light, and decide for yourself whether the step up is worth it.
What is the difference between insert and full-frame replacement?
- An insert fits a new window inside your existing frame, so the interior and exterior trim stay put. It is faster, cheaper, and cleaner. Full-frame takes the window out to the rough opening so the frame, sill, and flashing can be inspected and rebuilt. If the existing frame is sound, an insert is the right call. If it is rotted, out of square, or leaking, an insert just hides the problem.
How do I know which one my house needs?
- We tell you after we look, not before. Soft or spongy wood at the sill, visible rot, a frame that has racked out of square, or staining on the wall below the window all point to full-frame. If the frame is solid and you mainly want better glass and smoother operation, an insert does the job for less money. We recommend based on what we find, not on what is easier to install.
My windows are fogged between the panes. Can that be repaired?
- Fogging means the seal on the insulated glass unit has failed and moisture is now inside the pane, where you cannot clean it. In some cases the glass unit alone can be replaced while keeping the existing frame and sash, which costs considerably less than a new window. Whether that is worth doing depends on the age and condition of the rest of the unit. We will tell you honestly when a repair makes sense and when it is money spent twice.
How long does a window job take?
- Most whole-home insert projects are done in one to two working days. Full-frame replacement takes longer because each opening is stripped, inspected, and re-flashed, and any rot has to be addressed before the new unit goes in. We confirm the schedule before we start and tell you if anything changes mid-project.
Will new windows actually lower my energy bills?
- They help, though anyone promising a specific dollar figure is guessing. The honest version: replacing single-pane or failed double-pane windows with modern insulated glass makes the biggest difference, especially on west and south-facing walls that take Utah’s afternoon sun. If your windows are already decent double-pane units, new ones will improve comfort and drafts more than they will change the bill.
Do you offer financing?
- Yes. We work with several lenders to offer financing for window and full exterior projects. Ask during your estimate and we will walk through the available programs.
