Serving the Royal City

General Contractor in
Guelph, Ontario

We've spent over a decade renovating the Royal City — limestone-foundation century homes in Old University and the Junction, brick semis in Exhibition Park, mid-century side-splits out in the South End and Hanlon Creek, and modern infill near Stone Road and the U of G campus. Kitchen renos, basement underpinning, structural openings, full home renovations — we know how to work with Guelph's older housing stock without breaking the character that makes it special.

Built for Guelph homes

From limestone-foundation century homes to 1970s side-splits, we know the quirks of Royal City housing stock — knob-and-tube updates, plaster repair, basement underpinning, and modern open-concept conversions.

Recent Project Types in Guelph

A snapshot of the kind of work we take on across the Royal City — from century-home preservation to modern infill builds.

Century home opens in Old University

Knob-and-tube updates, plaster-to-drywall finishing, and load-bearing wall removals in the 1900–1920 brick homes that line Old University, Exhibition Park, and the streets near the General Hospital.

Limestone basement underpinning

Older Junction and downtown homes often have shorter basement ceilings on stone foundations. We dig deeper, pour new footings, and add livable square footage — alongside structural engineers when required.

U of G student rental finishes

Legal basement income suites near campus — proper egress windows, fire-rated assemblies, separate entrances, and city-approved layouts for landlords on streets like Gordon, Stone Road, and Edinburgh.
