Perth is Eastern Ontario’s showpiece of heritage stone — a town founded in 1816 whose limestone mansions, stone cottages and Tay River storefronts have been kept with rare care. Owning one of these homes means choosing materials the walls were built to live with, and that is exactly what lime-based finishes are.
Limewash: the finish Perth’s walls were built for
Before acrylic paint existed, stone and plaster walls were finished with lime. Limewash is breathable — it lets old solid-masonry and lath-and-plaster walls release moisture rather than sealing it in, which is why conservation-minded owners specify it. The soft, chalky movement it leaves behind looks like it has always been there, because in houses like these, it more or less has.
Venetian plaster for formal heritage rooms
Perth’s stone homes carry formal rooms unusually well, and venetian plaster suits them — a burnished lime finish with the depth of polished stone, appropriate to 19th-century proportions, applied by hand the way it always was. Dining rooms, entry halls and drawing-room fireplace walls are where we’re most often asked to work.
Microcement, discreetly modern
Where owners add modern bathrooms or kitchens to old houses, microcement keeps the intervention quiet: a seamless, waterproof, stone-like surface that doesn’t argue with the original fabric the way bright tile can.
Inns, B&Bs and boutique storefronts
Perth’s hospitality trade lives on atmosphere, and its stone inns, B&Bs and Foster Street storefronts are exactly where limewash and polished plaster earn their keep commercially — durable, photogenic surfaces that guests remember and post. We schedule commercial work around your occupancy, including split stages and off-season slots.
How it works from our Ottawa studio
We travel from our Ottawa showroom at 2183 Carling Ave (inside Alteriors, visits by appointment) to projects across the region. Most quotes start with photos or a short video of your space — free, with no site visit needed. For larger Perth projects we come out for an on-site consultation and bring physical sample boards so you can judge colour and texture on your own walls, in your own light. We’re regularly out along Highway 7 — Perth is about an hour from the studio, and photo quotes cost you nothing.
Frequently asked questions
Is limewash safe for a designated heritage home?
Lime finishes are generally the recommended approach for heritage masonry precisely because they’re breathable and reversible in a way modern films are not. For designated properties we’re happy to describe materials and method in whatever detail your heritage consultant or committee needs.
Can you match an existing historic plaster texture or colour?
Usually, yes. We make up sample boards in graded colours and textures and refine against your existing walls on site before committing to the full surface.
Do you repair old plaster before finishing?
We handle the surface preparation that decorative work requires — minor patching, consolidation and priming. Major structural plaster restoration we’ll flag honestly during the consultation so it’s done right before we finish over it.
