Concrete & Masonry

Concrete shows up in almost every exterior project here — patio slabs, walkways, driveway aprons, stoops and steps, and the footings under anything that is being added. It is the trade a remodel literally stands on, and the part where shortcuts stay visible for decades. The climate is the reason: concrete that freezes while it is still curing, or that sits saturated going into winter, fails in ways that cannot be patched, which is why pour dates here are a scheduling decision rather than a convenience.

Concrete cracks; the craft is deciding where. Control joints exist to give a slab's inevitable movement a straight, intentional place to happen instead of a wandering one, and in a climate that can swing fifty degrees in a day the joint layout is not decoration. A patio drawn with its joints — spaced to the slab's thickness, aligned to the geometry of the space — behaves for decades. One poured without them writes its own map.

Drainage is designed before finish is discussed. Every slab near the house slopes away from it, snowmelt against a foundation is the condition that matters most here, and where a new patio meets an existing yard the water has to be given somewhere better to go than the neighbour's wall or your own foundation. Flat-looking is a finish; flat is a defect. Exterior concrete here also has to survive freeze-thaw and de-icing salt, which makes air entrainment, correct finishing and jointing the difference between a slab that lasts decades and one that spalls in five winters.

Older masonry here ages in familiar ways, and almost all of it traces back to water and frost. Stoops and steps separate from the house and tilt because whatever they bear on was never below frost. Mortar in an old foundation or chimney goes soft and sandy at the joints. Slab surfaces spall and flake where de-icing salt and freeze-thaw have worked on them together. Retaining walls lean where drainage behind them was never provided, so the soil they hold freezes and pushes. Repair versus rebuild is a condition call made honestly — a lean that traces to the footing does not stay repaired — and new walls beyond modest heights bring engineering and permits, which is a feature of doing them once.

Finish is chosen against use and against the sun. Broom finish is the honest default outdoors — it grips wet and hides service life; smoother and decorative finishes trade maintenance and glare-heat for looks, and pavers answer a different question, trading a monolithic slab for a surface that can be opened and relaid. Each has a right place, and the design conversation is about which this project is.
