Capping and Trim in Brantford
Aluminum bent on site to wrap window and door trim, ending the repainting cycle and closing the gaps water uses.
Capping is the detail most people never think about and the one that decides whether a re-side looks finished. Brantford Siding Co forms and fits aluminum trim across Brantford and Brant County.
Formed on site, to the actual opening
Aluminum coil stock is run through a brake and folded to match the exact profile of the trim it is covering. That matters because the openings on an older house are not standard sizes. Frames have settled, sills have been rebuilt, and the trim on the front elevation may be a different depth from the trim on the side. Ordering pre-formed trim to a catalogue dimension means fighting the house. Bending it on site means the metal fits what is actually there.
It is a fabrication skill rather than a supply question, and it is the clearest visible difference between a professional exterior and a wrapped one. Crisp folds, tight corners, consistent reveals along the length of a run.
Why it is worth doing
The obvious reason is paint. Wood trim around windows and doors is the most exposed painted surface on the house, and it is the one that needs redoing most often. Capping it ends that cycle permanently.
The less obvious reason is water. Old trim develops gaps at joints and where it meets the cladding, and those gaps are a direct path into the wall. Correct capping laps each piece so water runs outward and downward, with a drip detail at the head of the opening that throws water clear of the frame below. A significant proportion of the window leaks we are called about are trim problems rather than window problems.
Where it must not be used
Capping over rot is the one thing we will not do. Aluminum over soft wood traps the moisture that caused the damage against the wood, out of sight, where it continues quietly. Where the trim underneath has gone, it comes off and gets replaced before anything is wrapped. It costs more that day and it is the only honest way to do it.

Capping and Trim Questions
What does capping actually mean?
Wrapping existing wood trim in aluminum sheet, folded on site to the exact profile of that trim. The wood stays where it is and does the structural work; the aluminum takes the weather. Done well, the finished opening looks like a clean painted surface that never needs painting again.
Can you cap over rotten trim?
No, and it is worth being firm about this. Capping over soft wood seals moisture in against material that is already failing, and it hides the damage from view while it gets worse. Where the trim is rotten it gets replaced first, then capped. Anyone willing to cap rot is doing you real harm.
Will capping stop my windows leaking?
It can help significantly, because a large share of window leaks are water tracking into gaps in old trim rather than through the window itself. Correct capping with proper laps and a drip detail at the head sheds that water outward. If the leak is through the window unit or the wall assembly, capping will not fix it, and we will tell you that.
Is it done at the same time as siding?
Almost always, because that is when the openings are accessible and the flashing details can be integrated with the new cladding rather than added afterwards. It can also be done on its own where the siding is fine and only the trim is tired.
