Aluminum Capping & Trim Installation in Kitchener-Waterloo
D&D Exterior Finishing wraps exterior trim in custom-bent aluminum capping throughout Waterloo Region. Capping eliminates the need to ever paint window frames, door surrounds, or fascia again — while creating a weatherproof barrier that protects the wood underneath from Ontario's harsh climate.
Why Aluminum Capping Is the Smart Choice for Ontario Homes
Exterior wood trim requires painting every 3–5 years in Waterloo Region. Peeling paint leads to moisture infiltration, rot, and ultimately costly repairs. Aluminum capping wraps your existing wood trim permanently in a colour-baked, UV-resistant metal shell — forming a watertight seal that never needs painting and won't rot, crack, or fade. The upfront investment pays for itself in eliminated maintenance costs within just a few paint cycles.
Types of Capping We Install
Window brickmould, casings, and sills are wrapped in custom-bent aluminum coil stock that fits exactly to your trim profile. Window capping eliminates the most maintenance-intensive trim on the home and seals the joint between window frame and siding against water infiltration.
Entry door surrounds, brick moulds, and door frames are wrapped in aluminum to protect against the heavy moisture exposure they receive from rain and snowmelt. Door capping is especially valuable for north-facing and west-facing entries that receive the brunt of Ontario weather.
Decorative corner boards, band boards, belly boards, and architectural trim elements can all be wrapped in aluminum capping — bringing the entire exterior trim package under permanent protection for a unified, clean appearance that holds its colour for decades.
Wrapping existing fascia boards in aluminum capping is the most cost-effective way to stop fascia rot and eliminate roofline maintenance. We custom-bend fascia caps to fit your exact board width, wrap all returns and corners cleanly, and coordinate colour with your soffit and eavestrough.
Our Capping Installation Process
- Measure & Colour Selection — We measure each trim component and take note of your existing or desired colour scheme. All aluminum coil stock is sourced in your chosen colour — no painting ever required.
- Substrate Inspection & Repair — Before capping, we inspect the underlying wood for rot or moisture damage. Any compromised wood is repaired or replaced to give the aluminum cap a solid, long-lasting base.
- Custom Bending on Site — Aluminum coil stock is custom-bent on site using a brake press to match your exact trim profiles — including sill returns, corner wraps, and decorative details. No gaps, no filler strips.
- Installation & Sealing — Caps are secured and all joints, corners, and edges are sealed with colour-matched caulk. The completed work is inspected with you to confirm a tight, professional finish on every surface.
Why Waterloo Region Homeowners Trust Us
- ✓ Custom-Bent On Site — We don't use pre-formed generic pieces. Every cap is bent to fit your trim exactly — no gaps, no visible seams, no corner pieces that don't line up.
- ✓ Rot Repaired Before Capping — We never cap over damaged wood. Any rot is repaired first so the capping performs as intended for decades.
