# Exterior Supply Co — Windows, Doors, Garage Doors & Siding Supplier in Hanover, ON

Exterior Supply Co is a Hanover-based building-envelope supplier and installer serving the Grey-Bruce-Wellington corridor. The shop stocks and installs vinyl and aluminum windows, entry doors, interior doors, garage doors, siding, awnings and screens — essentially the full exterior-envelope toolkit a homeowner needs for a full-home retrofit or a phased upgrade. The scope is meaningfully different from a general contracting firm, and this profile corrects the directory’s earlier “renovation company” label to reflect the supplier-installer reality.

## Services

- **Vinyl windows** — full replacement and new-construction windows across the standard residential sizes and configurations.
- **Entry & interior doors** — residential entry systems, patio doors, and interior door packages.
- **Garage doors** — insulated and non-insulated residential garage doors with hardware and opener supply.
- **Siding** — vinyl, aluminum, and composite siding supply and installation for full-home re-clads.
- **Awnings & screens** — retractable awnings, screen rooms and window screen replacement.

## Service Area

Hanover, Walkerton, Owen Sound, Collingwood, Kincardine, Port Elgin, Mount Forest, Guelph, Fergus, Elora, Listowel, Palmerston, Harriston, Grand Valley, and Arthur.

## Why it’s on home.renovation.reviews

Exterior Supply Co is the directory’s first Hanover / west Grey County materials-and-installation anchor and its first dedicated building-envelope supplier covering the inland Grey-Bruce-Wellington triangle. It slots alongside the Collingwood envelope bench (Van Dolder’s) and gives homeowners on the Hanover / Owen Sound / Guelph axis a vetted supply-and-install option for whole-home exterior retrofits.
