Professional door capping (aluminum cladding) in Toronto & GTA. Eliminate painting, prevent rot, and give your doors a finished look. 29+ years.
Door capping wraps the exterior wood trim around your doors with durable aluminum cladding. The result is a maintenance-free, weather-resistant finish that eliminates painting and prevents rot.
We custom-bend aluminum on-site to precisely fit your door frames. Choose from a wide range of colours to match or complement your home's exterior. The finished product looks crisp and professional for decades.
Door capping is often done alongside window capping and siding projects, but can be a standalone service to refresh your entry without a full renovation.
We always inspect wood trim before capping. Capping over rotted wood just hides the problem temporarily. If rot is present, we'll recommend repair or replacement first.
Understanding the importance of proper maintenance and quality workmanship.
Never paint your door trim again. Aluminum maintains its colour for decades.
Wood trim is vulnerable to moisture. Aluminum capping creates a waterproof barrier.
Crisp, factory-finished look that enhances your home's curb appeal.
Sealed aluminum eliminates entry points for carpenter ants and other pests.

What aluminum door capping is, why wooden door frames break down, how custom-bent capping is installed and what to check before your frames are covered.
Door capping (sometimes called door wrapping or trim cladding) is a layer of aluminum that is custom-bent to fit over the exterior wood trim and brickmould around a door. It shields the wood from rain, snow and sun so it no longer needs painting, and gives the entrance a clean, crisp finish.
Because every door frame is slightly different, the aluminum is measured and bent on-site with a brake so it fits each piece of trim precisely.
Door frames are exposed to more water than most parts of a wall. Rain runs down the door, splashes up from the step and collects at the bottom corners of the frame. In winter, snow piles against the threshold and melts repeatedly. Over time paint cracks, water soaks into the end grain and the wood begins to rot, usually starting at the bottom of the side jambs.
Capping should never be used to hide rotten wood. If aluminum is installed over damaged trim, the rot continues underneath, unseen, and can spread into the framing and subfloor. Before any capping goes on, we check the trim and brickmould for soft spots and replace damaged sections with sound material.
This step is what separates capping that lasts for decades from capping that has to be torn off after a few years.
A well-executed capping job looks like it came from the factory. It relies on accurate measurements, careful bending and good sealing at the joints.
If your door frames are showing wear, your window frames are usually not far behind. Capping doors and windows together keeps the colour and finish consistent across the whole exterior and is more efficient than doing them separately.

Common questions about door capping services.
We offer a wide range of standard colours. Custom colours can be ordered for an additional cost and lead time.
We don't cap over damaged wood. If rot is present, we'll repair or replace the trim first. Capping over rot just delays the inevitable.
A typical door takes 1–2 hours. Most homes can have all doors capped in a single day.
Slightly. The aluminum adds about 1/16 inch of material, and the profile may differ slightly from your original wood trim. Most homeowners prefer the finished look.
Capping with properly sealed joints can help reduce air and water getting in around the exterior trim. Drafts through the door itself are usually a weatherstripping or door-fit issue, which we can point out during the visit.
Yes, but the rotted wood must be repaired or replaced first. Capping over rot traps moisture and allows the damage to keep spreading out of sight.
No. The aluminum has a baked-on finish, so the capped trim doesn't need painting. An occasional wash keeps it looking clean.
