Kemptville has quietly become one of the most interesting places to build near Ottawa. Twenty-five minutes down the 416, North Grenville’s estate lots and golf-course streets are filling with custom homes whose owners chose the town precisely because they didn’t want a cookie-cutter build — and the same thinking applies to their walls. That’s where we come in.
Venetian plaster for Kemptville custom builds
A custom home deserves at least one surface that couldn’t have come off a production line. Venetian plaster — real lime and marble dust, burnished by hand — brings depth and a soft stone sheen to great-room feature walls, primary bedrooms and fireplace surrounds. On the tall ceilings common in Kemptville’s newer builds, it reads as architecture rather than decoration.
Limewash for warmth on big open-plan walls
Open-concept plans live and die by their largest wall. Limewash breaks up those expanses with a cloudy, hand-brushed movement that flat paint can’t imitate, in mineral pigments that shift gently through the day. It’s our most-requested finish for dining rooms, bedrooms and hallway runs out here.
Microcement for ensuites and walk-in showers
Kemptville ensuites trend large and spa-like, and microcement is the finish that completes them: one seamless, waterproof surface across shower walls, floors and even vanity tops, with no grout to scrub. It’s equally at home on a polished basement floor.
Not just the new builds
Kemptville’s older village core — the streets around Clothier and Prescott — holds a different kind of house: solid, modest, often mid-century or older, with good bones and dated surfaces. A single limewashed living-room wall or a plastered fireplace does a lot of modernizing here without erasing the character that made the house worth keeping. We quote these the same way: photos first, firm number, no pressure.
How it works from our Ottawa studio
We travel from our Ottawa studio at 2183 Carling Ave (inside the Alteriors showroom, 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 Kemptville 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. The 416 makes North Grenville one of our easiest runs — often under 30 minutes.
Frequently asked questions
Can you coordinate directly with our builder or designer?
Yes — a large share of our Kemptville work comes through builders and interior designers. We schedule around drywall, priming and trim stages, and we’re comfortable working from a designer’s spec or mood board.
How far in advance should we book for a new build?
Once drywall is up you generally have a few weeks of lead time, but booking 4–6 weeks ahead keeps you off the critical path. Send us the plan or photos and we’ll slot you in around your other trades.
What does a venetian plaster feature wall cost in Kemptville?
Most single feature walls land in the low four figures depending on size, finish and colour. Photo quotes are free and firm — text pictures of the wall with rough dimensions to 613-255-1512.
