Window Well Installation in Vaughan, ON | OCM Excavation

OCM Excavation installs and upgrades window wells across Vaughan, with a heavy concentration of work in Maple, Kleinburg, Thornhill Woods, and Patterson where the original builder-grade galvanized wells installed during the subdivision boom are now reaching the point where homeowners want a premium upgrade. A window well is a curved steel or composite barrier that holds back soil from a basement window, allowing the window to sit safely below grade. Single-well projects in Vaughan run 1 to 3 days on site. Call 416-317-3090 for a free quote.

Why Vaughan window wells are getting replaced

The subdivisions that built out across Vaughan from the late 1980s through the 2000s used the cheapest functional galvanized well stock available at the time. They are still standing, but the gauge is thin, the bottoms are starting to rust, and the dimensions usually do not meet egress code for a basement bedroom conversion. Vaughan homeowners we work with typically reach out for one of three reasons:

Premium upgrade. Replacing builder-grade galvanized with a 50-plus year composite well so the well matches the quality of the rest of the home.
Foundation waterproofing. A rusted, leaf-clogged well holds water against the window frame and the foundation parging, which is one of the most common Vaughan basement leak sources.
Egress code compliance. The Ontario Building Code (9.7.1.3) requires every basement bedroom to have an egress window. A correctly sized well is what makes that legal.

Materials we install in Vaughan

Galvanized steel in 16 to 22 gauge is the most affordable like-for-like swap. Aluminized steel costs more but holds up longer against winter salt. Composite PVC and HDPE wells are our most-requested Vaughan upgrade — 50-plus year service life, no rust, low-profile aesthetic. Poured concrete wells are the right call when a window has been enlarged for egress and standard sizes do not fit. We walk through each option during the on-site quote so you can match the well to the rest of your Vaughan property.

Our installation process

We excavate around the window 24 to 36 inches deep and roughly 12 inches past the perimeter of the new well. On tight Thornhill Woods backyards with finished landscaping, we hand-dig and protect the surrounding plantings. On larger Kleinburg lots we run a Yanmar SV40 mini-excavator with a thumb attachment. Where Enbridge gas or Alectra hydro lines run close to the foundation, we switch to vacuum excavation to avoid strikes.

Once the hole is open, we lay 6 to 12 inches of clear drainage stone at the base, bolt or concrete the new well body to the foundation wall, tie the well drain into the existing weeping tile where one is functional, backfill with drainage stone, and finish grade the surrounding soil away from the house. A polycarbonate cover is offered as an add-on to keep leaves, snow, and pests out.

Typical project size and timeline

For Vaughan window well installation, budget $1,500 to $4,500 per window. A like-for-like galvanized swap on an accessible side yard sits at the lower end. A composite egress well with a new drainage tie-in for a basement bedroom conversion sits at the upper end. A single well takes 1 to 2 days. A full perimeter of 4 to 6 windows runs 4 to 7 days. Vaughan window well work often pairs with foundation waterproofing, basement underpinning, or a walk-up basement conversion.

Frequently asked questions

How much does window well installation cost in Vaughan?

Most Vaughan window well projects land between $1,500 and $4,500 per window. Galvanized like-for-like swaps sit at the lower end. Composite egress wells with a new drainage tie-in for a basement bedroom conversion sit at the upper end. Full-perimeter packages of 4 to 6 wells carry a per-window discount that we work out during the site quote.

Is a composite well worth the upgrade in a Maple or Kleinburg home?

For most Vaughan homeowners staying in the property long-term, yes. Composite PVC and HDPE wells carry a 50-plus year service life, do not rust, and have a cleaner low-profile look that matches premium landscaping. The upfront cost is higher than galvanized, but the lifetime cost is lower and there is no second replacement to schedule.

Do I need a permit in Vaughan?

A like-for-like window well replacement generally does not require a permit. If you are enlarging the window for egress or cutting a new opening in the foundation, that does trigger a building permit and a structural engineer review. We will tell you which category applies during the quote.

How long does the work take?

A single Vaughan window well installation is 1 to 2 days on site. Two to three wells run 2 to 4 days. A full perimeter of 4 to 6 windows is 4 to 7 days, depending on access, soil conditions, and whether we are tying into existing weeping tile.

What size do I need for an egress bedroom?

OBC 9.7.1.3 requires a minimum 36 by 24 inch clear floor area for an egress well, with enough projection from the wall to let the window swing fully open. Most Vaughan basement bedroom conversions use 48 by 30 to 60 by 36 inch wells.
