FAQ

Frequently Asked Questions

It depends on your home's age and neighbourhood. Older homes along the Talbot Street, Sunset Drive and First Avenue corridors more often call for brick-to-brick, while newer Confederation and Orchard Park subdivisions are typically well-suited to retrofit. We confirm the right approach as part of your quote.
No. Southgate and Mitchell Hepburn are mid-century neighbourhoods, older than the newer subdivision growth seen in Confederation and Orchard Park. This difference in construction era affects whether retrofit or a more involved replacement approach is the better fit, which we confirm during your quote rather than assuming based on general neighbourhood age alone.
Yes — Elgin County snow loads and open-field wind exposure make triple-pane a noticeable upgrade for comfort and energy bills, especially on north and west elevations.
Yes, in many cases. These corridors hold early 1900s brick homes where original openings have often settled over time, making full brick-to-brick installation the typical recommendation, along with reinforced frames and triple-pane glass to handle Elgin County's open-field wind exposure on north and west-facing elevations specifically.
Yes — we handle masonry repair and brick matching where openings are enlarged or altered so the exterior stays consistent with the original brickwork.
Heritage-matched profiles for the older Talbot, Sunset and First Avenue corridor homes require individual shop templating to preserve the original brick openings' proportions, which adds production time compared to standard stock units used in newer Confederation and Orchard Park subdivisions.
