Premium renovations, additions, and heritage restoration for Cambridge's finest areas — the Victorian streets of West Galt, the estate lots of Blair, and the countryside of North Dumfries. Engineering-led design-build since 2007.
Cambridge rewards a builder who understands old homes. West Galt's Victorian and century houses — many in the historic Dickson Hill area near the Grand River — need modernization that respects their architecture, not erases it. Blair and North Dumfries bring estate lots and rural properties where additions and custom work have room to breathe. Caliber's engineering-first process suits both: we treat structure, heritage detail, and modern systems with equal seriousness.
A recent Cambridge project added a full two-storey extension in Galt — new structure, board-and-batten exterior, high-performance windows, and a continuous-insulation envelope — the kind of substantial addition that transforms an older home without compromising it. Founded in 2007 by two engineering graduates and run by a team of nine, Caliber manages every project end to end under one accountable team.
Established and estate areas we serve in and around Cambridge include West Galt, East Galt, Blair, North Dumfries, Ayr, St. George, Preston Heights, and surrounding areas.

Yes — it's one of our specialties. West Galt's Victorian and century homes, including the historic Dickson Hill area, need modernization that respects their architecture. We balance heritage detail with modern structure, mechanical systems, and finishes, and our engineering background means structural changes in old homes are handled properly rather than improvised.
Yes. A recent Galt project added a full two-storey extension with new structure, a board-and-batten exterior, high-performance windows, and a continuous-insulation building envelope. Blair and North Dumfries estate lots offer room for substantial additions and custom work, and we manage the full scope from foundation through finish.
Yes. North Dumfries (including Ayr) and the Brant County village of St. George are within our service area — the rural and estate properties there are well suited to additions, custom kitchens, and whole-home renovations. We bring the same engineering-led process to country properties as we do to homes in the city.
Premium and heritage work in Cambridge varies widely by scope. A high-end custom kitchen typically runs $60,000 or more; a main-floor renovation with structural changes and an addition can range from $200,000 well into the $500,000s. Caliber provides a clear, all-in project price after design, and for projects with structural or regulatory unknowns — common in older West Galt homes — a paid feasibility study resolves the variables before you commit.
