Guelph Projects

Built for Guelph homes — old and new

Guelph is famous for its 1800s limestone heritage homes — Old University especially — alongside 1990s Kortright Hills and 2000s Westminster Woods subdivisions. Limestone openings need different handling than brick. Common Guelph 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 Guelph permit assistance. Flexible financing is available, or you can request a free quote any time. See what Guelph-area homeowners say about working with us.

FAQ

Frequently Asked Questions

Yes. Guelph Building Services requires zoning sign-off in addition to the building permit when an opening size changes — common in Old University limestone homes. We prepare the zoning compliance notes alongside the structural details so the file clears review without a second round of comments.
Yes — limestone openings require careful measurement and sometimes custom flashing. We handle the masonry-adjacent details in-house.
Often — original builder-grade dual-pane has typically reached end of life. Triple-pane upgrades improve comfort and bills.
Yes. Downtown Guelph and Old University use sandstone and limestone surrounds with a deep reveal — we set the new units back to match the original glass plane so the stone shadow line and reveal proportions stay correct.
7–9 weeks for limestone heritage openings — custom flashings extend the shop build — and 6 weeks for stock subdivision retrofits in Westminster Woods or Kortright Hills.
