Keswick Projects

Built for Keswick homes — old and new

Keswick is the largest community in the Town of Georgina, sitting on the south shore of Lake Simcoe with everything from 1960s bungalows around The Queensway to newer Simcoe Landing subdivisions and year-round waterfront cottages in Sutton and Jackson's Point. Lake Simcoe wind and winter cold snaps are the drivers here — most projects specify triple-pane glass with argon fill and warm-edge spacers, tight-sealing casement windows for waterfront elevations, and full brick-to-brick installations on older cottages that have been converted to year-round homes. Every install is completed by Trust Build in-house crews, backed by a lifetime transferable product warranty and 25-year labour warranty, with 0% financing available for 12 months. Common Keswick projects include casement window, tilt & turn, and bay window replacements, along with steel and fiberglass entry doors, sliding patio doors, full masonry work, code-compliant egress windows, and Keswick permit assistance. Flexible financing is available, or you can request a free quote any time. See what Keswick-area homeowners say about working with us.
