What window cladding does (and what it should look like when it's done right)
Window cladding—often called window capping—is a formed metal wrap installed over exterior wood trim around the window. The goal is straightforward: protect vulnerable trim from moisture and UV, reduce maintenance, and give the opening sharp, consistent lines.
Done properly, the cladding sits flat, follows the window's geometry, and sheds water away from the frame. Corners should be crisp, seams should be planned so they are tidy and logical, and there should be a clean transition to siding, stucco, or brick. In Calgary, that attention to detail matters because wind-driven rain and quick freeze-thaw cycles can punish any gap that traps water.
Calgary Window Installer focuses this service on the parts you can see and the parts that prevent problems: accurate measuring, correct bends on the brake, smart seam placement, proper drip edges, and careful sealing where it belongs. The end result should look like it was built with the house, not added later.

Weather-aware exterior protection
Calgary window cladding: built for sun, wind, and freeze-thaw
Exterior trim takes more abuse than most people realize. South- and west-facing windows get strong UV that bakes paint and dries out caulking. Wind can drive rain into tiny joints. Then temperatures swing and any trapped moisture expands when it freezes.
Good window cladding installations account for that reality. We form the metal to manage water, not just to cover wood. That means a positive slope where it belongs, edges that direct water away from the window assembly, and clean closures so water is less likely to sit behind the wrap.
If your home is in neighborhoods with a lot of older wood-trim details like Altadore or Bowness, cladding can be a practical way to keep the character of the trim profile while cutting down on scraping and repainting. In newer areas like Evanston or Mahogany, where openings are more uniform, consistent capping lines can sharpen the whole elevation and help match new windows to existing finishes.
For projects that also include replacing units, it is often best to plan cladding together with window installation so the exterior finish lands correctly at the frame and looks intentional.

Measured, formed, and finished
What's included in our window capping work
Brake-formed aluminum cladding
We form bends for head, jamb, and sill areas so the wrap sits tight and maintains straight lines across the opening.
Corner and seam detailing
We build corners to look clean and stay stable. Seams are placed intentionally so they are less noticeable and less exposed.
Terminations and sealing where needed
We seal at the correct transitions and avoid over-caulking that makes future work messy. The goal is water management and a tidy finish.
Color and finish matching
We help you choose a finish that suits your frames, soffit and fascia, or existing trims so the cladding looks like part of the exterior design.
Careful cleanup and final walkthrough
We check edges, corners, and caulk lines up close, then tidy the work area so you are not left with metal scraps or fasteners.
From inspection to final detail
How a window cladding project typically runs
Assess the openings and trim condition
We look for soft wood, failed paint, open joints, and tricky transitions such as brick mold, stucco returns, siding J-channel, or deep sills. If trim is deteriorated, we flag what needs repair before wrapping.
Confirm profiles, seams, and color
We align on the look: what stays visible, what gets wrapped, and where seams will land. This is also when we confirm the finish so it matches the exterior.
Form the metal and test fit
Pieces are bent to measured dimensions so they sit flat without oil-canning and keep consistent reveals. Any adjustments are made before final fastening and sealing.
Install, seal transitions, and inspect
We install the cladding, seal only where required at terminations, and do a close inspection of corners, drip edges, and lines. You get a clear view of the finished details.
Pricing follows the detail
How Much Does Window Cladding Cost in Calgary?
Most window cladding projects in Calgary typically range from about $250 to $900 per window, depending on window size, trim depth, and how complex the returns and sill details are. A straightforward cap on a standard opening is usually at the low end, while larger picture windows or bay-style details tend to price higher.
Your final price depends on access—ladders versus staged areas—trim condition and prep, the number of pieces and seams required, and color or finish matching. Exact pricing is confirmed after an on-site measure and condition check.

Protection with cleaner lines
Common reasons Calgary homeowners choose window cladding
Most people start looking for Calgary window cladding when trim becomes a repeat maintenance project. If you have been repainting the same sills and jambs every few seasons, capping can protect the substrate and keep the exterior looking sharp.

Cladding is not a fix for rotten wood, but once repairs are made, wrapping helps protect the repair from weather exposure.
Mismatched exterior finishes
Fresh window frames beside tired trim can make the whole elevation look uneven. Consistent capping helps tie the exterior together.
Caulk lines that keep cracking
Some joints move with temperature swings. Well-formed metal reduces reliance on oversized caulk beads to look finished.
Cleaner, straighter trim lines
This is especially noticeable around larger openings where slight waves or uneven paint buildup stand out. When comparing options, ask how corners, head drip edges, and terminations into siding or stucco will be handled.
Common questions
Window cladding and capping FAQs
Is window cladding the same thing as window capping in Calgary?
Yes, most homeowners and contractors use the terms interchangeably in Calgary: both refer to wrapping exterior window trim with formed metal, usually aluminum. The important part is the detailing, not the label, so confirm exactly what trim areas are being wrapped and how seams and corners will be finished.
Can you cap over existing wood trim, or does it need to be replaced first?
You can cap over existing wood trim if it is solid, dry, and properly fastened, but any soft or rotten wood should be repaired first. Cladding hides the wood, so you want the substrate stable before it is wrapped to avoid trapping problems behind the metal.
Will cladding change how my windows drain or affect leaks?
Window cladding should not interfere with drainage when it is formed and installed correctly, and it should never block weep paths or trap water at the head or sill. If you already have signs of a leak, the source needs to be identified first because capping alone is not a waterproofing repair.
What materials are used for window capping?
Most window capping uses brake-formed aluminum coil because it is workable, durable, and available in many finishes. The exact thickness, finish, and color availability can vary, so matching to existing trim or soffit and fascia is typically part of the planning.
How long does window cladding take?
Many homes can be completed in a day or two, but timing depends on the number of openings, access, and how many custom details each window needs. Larger openings, multiple elevations, or repair work on the underlying trim can extend the schedule.
How do I know if the cladding will look “bulky” around the window?
It comes down to how the metal is formed and how the returns are planned at the frame and wall surface. A careful measure and a clear plan for reveals and seam placement prevents oversized-looking wraps and keeps lines consistent across all windows.
