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.

FAQ

Frequently Asked Questions

Many homes in Keswick and Sutton started as seasonal cottages along Lake Simcoe and were later converted for year-round living, which sometimes means irregular or settled window openings. We assess the existing frame condition as part of your quote to determine whether retrofit or brick-to-brick installation is the better fit.
Yes. We install across Keswick North and South, Simcoe Landing, Sutton, Jackson's Point, Pefferlaw and the surrounding Georgina waterfront and rural areas.
Yes — Lake Simcoe wind exposure and cold overnight lows make the comfort, condensation and energy-bill improvement clearly noticeable, especially on north and west elevations and waterfront cottages.
Yes. We file building permits with the Town of Georgina for new openings, lintels and egress windows, and coordinate with the Lake Simcoe Region Conservation Authority when a property is inside a regulated shoreline area.
Yes. Cottage-to-home conversions are one of the most common Keswick projects — full brick-to-brick or stud-to-stud installations with triple-pane glass and code-compliant egress in bedrooms.
Not entirely. Simcoe Landing is a newer subdivision with more consistent, modern construction, so retrofit installation is generally the better fit there. Older bungalows around The Queensway were often built with lower-grade original windows for the era, which is why full replacement — rather than a simple retrofit — tends to deliver a bigger improvement in comfort and energy performance on these older homes specifically.
Yes — 0% interest financing is available for 12 months on qualifying window and door projects. Ask for details when you request your free quote.
