Garden City Homes. Masters-Level Work.
Older Home. New Standard.
A lot of St. Catharines housing predates modern code — the century homes of Old Glenridge and Western Hill, and the older streets through the downtown core and north end. That usually means narrow, original basement windows that fall short of today's bedroom egress requirements. Whether you're finishing a basement suite, adding a legal bedroom, or just bringing in more light and a safe exit, it has to be done right.
Egress Masters handles the full scope: precision concrete cutting, window well installation, and drainage stone work. We build to Ontario Building Code egress requirements and back every installation with a 3-year water-free warranty.
- Legal basement bedroom compliance — minimum 3.8 sq ft opening, maximum sill height met.
- Precision concrete cutting and block removal with no damage to surrounding foundation.
- Galvanized or custom window well, mechanically fastened and filled with drainage stone.
- $5M liability coverage, 3-year water-free warranty, and one crew who owns the job start to finish.
3-Year Warranty. Weeping Tile or Not.
Many St. Catharines homes sit on Niagara's heavy clay over a high water table, with original weeping tile that's failed, missing, or decades old. Most contractors walk away from the warranty conversation the moment drainage comes up. We don't.
Our mini dry well technique replaces the need for existing drainage infrastructure at the window well. We excavate to the footing, remove all native soil, and backfill the entire bowl with ¾" clear drainage stone. The result is a 4-foot-wide by 30-inch-deep primary well sitting on a 24-inch mini dry well that runs the full depth to the footing. Water entering the well disperses naturally into the stone — and it would need to rise 48 inches to reach your sill.
That's why our 3-year water-free warranty holds even when there's no weeping tile.
- Excavated to footing — native soil fully replaced with ¾" clear drainage stone.
- 4 ft wide × 30 in deep primary well sits above a 24 in mini dry well.
- Water must rise 48 inches inside the stone bowl to reach the window sill.
- 3-year water-free warranty applies with or without existing weeping tile.
Safer, Brighter, Basements.
Every service we offer in St. Catharines and Thorold is done by our own crew — no subcontracting, no handoffs. From the initial cut to the final stone grade, the Masters way means one team owns the job start to finish.
