What each material actually is
Cellular PVC trim is solid board stock cut and fastened around windows, doors, and corners. It replaces the wood trim board itself. Aluminum capping is thin coil bent on site and wrapped over existing wood trim when the wood underneath is still sound.
Anodized aluminum is a step up from standard painted coil: black and bronze finishes are baked into the metal and hold color longer than white capping that chalks out after years in NJ sun.
- PVC: board stock, no rot, factory or paintable finish
- Aluminum capping: coil wrap over sound wood
- Anodized: black or bronze accent refresh
- Both bent and cut on site, not catalog one-piece units
When PVC trim is the better call
Choose PVC when wood is rotted, when you want true board stock at openings, or when curb appeal on the front elevation matters for resale. PVC also makes sense on full siding tear-offs when sheathing is open and flashing can be rebuilt correctly.

- Rotted sills, corners, or rake boards
- Bay and box window surrounds
- Front elevation priority streets
- Full replacement with open walls
When aluminum capping or anodized coil fits
Aluminum capping fits when wood is solid and budget is tighter, or when you need the whole house wrapped in one visit. Anodized black or bronze coil is the popular refresh when siding field is sound but white cap looks dated.
Many homeowners put PVC or anodized accents on the front and standard aluminum on back and sides. NJ Vinyl Siding documents that split in writing so there is no confusion on order day.
- Sound wood, faded cap only
- Full perimeter budget plan
- Black or bronze accent at windows
- Back and sides not seen from street
Retrofit over existing siding
Neither PVC nor aluminum requires a siding tear-off. NJ Vinyl Siding ties new trim into existing J-channel and flashing on vinyl, Ascend, Hardie, and older aluminum-sided homes across Bergen and Passaic counties.
We check for hidden rot before capping. Trapping water behind new metal over punky wood is a shortcut we do not take.
- Works over vinyl, Hardie, Ascend, and aluminum field
- J-channel and flashing integration
- Rot repair before cap or PVC goes on
- Trim-only jobs common on sound siding

Common questions
PVC vs aluminum FAQ
PVC trim costs more upfront but eliminates rot and repainting at openings. Aluminum capping is the right call when wood is sound and budget is tight. NJ Vinyl Siding shows both options with written pricing so you decide with real numbers, not guesses.
