Discuss aluminum capping for exterior trim with the existing material, condition, profile and finish clearly identified.
Formed aluminum capping covers suitable exterior trim with a shaped metal finish. Around windows, doors and roof edges, it can create a consistent appearance while reducing the amount of exposed trim that needs repainting.
The visible result depends on bends, corners and how the metal meets neighbouring surfaces. Colour and profile choices can either blend into the siding or give the opening a sharper outline.
Capping is a finish, not a repair for deteriorated wood. Soft or damaged trim and the source of moisture need attention before they are concealed by new metal.
Joints, drainage paths and adjoining finishes deserve as much attention as the broad visible face. A quote should identify the trim being covered and any repairs needed to support the new finish.
Choose a location page for property planning details, related services and an enquiry route. Confirm the property address, requested scope and availability directly before arranging work.
In our clients’ words
Siding & roofline
"Had all our windows and doors capped last fall. D&D's team custom-bent everything on site and the colour match to our siding is perfect. Not a single piece of painter's tape has touched this house since."
Siding & roofline
"I manage four rental properties and had D&D cap the fascia and window trim on all of them. The tenants noticed the difference immediately. No more calls about peeling paint at the roofline."
Siding & roofline
"Professional from estimate to cleanup. They found some rot behind one window frame and repaired it before capping — I would never have known otherwise. That's the kind of honesty you want on a job like this."
Resolve deteriorated trim and moisture concerns before covering, with any additional repairs agreed separately.
Confirm how the formed metal meets the opening, preserves intended drainage and finishes at corners.
Photograph each elevation and close details of corners or damaged trim from an accessible position.
Mention windows, doors or siding that may be changed soon so the work can be sequenced sensibly.
Review actual colour and profile samples alongside the surfaces that will remain.
Identify window, door and roof-edge sections involved.
Record visible damage and questions about underlying repairs.
Review material, formed profile, colour and adjoining surfaces.
Keep preparation, access and finishing responsibilities together.
No. It covers suitable trim but does not restore deteriorated material beneath it. Have suspect areas assessed and agree the repair scope before they are concealed by the new covering.
It can reduce exposed surfaces that need repainting, but the finished assembly still needs appropriate care and review of joints or damage. Keep the material and finish instructions rather than assuming a permanent maintenance-free result.
A local scope can be discussed. Compare the new colour and profile with nearby openings and identify whether removing existing covering may reveal repairs that are not visible in an initial photograph.
Mention planned window work at the enquiry stage. The replacement method and trim details can change what is covered, so coordinating the sequence helps avoid removing new capping to finish another project.
Water entry can involve the window, flashing, wall or trim junction. Capping should follow assessment of the cause; do not treat a new outer covering as proof that an unidentified leak is resolved.
Compare the exact openings, underlying repairs, formed profile, material, colour, corners and removal work. Clarify whether adjacent painting or cladding repairs are included rather than comparing only a total number of windows.
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.
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.
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.
