Old floors, older houses, and what's underneath them
Close to a third of Hamilton's homes were built in 1960 or before, and roughly one in six predate 1946, concentrated in neighbourhoods like Durand, Beasley, and Landsdale in the lower city. That history means original strip hardwood is often still there, hidden under carpet laid decades later, and sanding and refinishing it is usually the stronger answer for both cost and the house itself. It also means diagonal board subfloors show up more often here than in newer municipalities, and those boards move seasonally in a way plywood does not.
Flatness is the measurement that decides whether a subfloor is ready, and it is not the same thing as level. A sloping century-home floor can be perfectly flat locally; a level one can still fail a straightedge check. The bigger the tile or the wider the plank, the less it can flex over a dip or a hump, which is why a board subfloor that suited the original strip oak sometimes needs levelling before a large modern tile goes down.
Acclimatisation is not about waiting a set number of days with the boxes sitting in the room. It is about the house running at its normal indoor temperature and humidity, wet trades finished and dry, and the flooring reaching a matching moisture content that we confirm with a meter. Several engineered and resilient products need almost no wait, and a few manufacturers say directly not to open the boxes early.
Hamilton is more particular than most cities about basement water: waterproofing or dampproofing a foundation wall, replacing weeping tile, and adding a sump pump or backwater valve all require their own building permit here. That is a useful thing to know before flooring goes into a basement, because a properly fixed water problem is a very different substrate than one that has just been carpeted over. Either way, a slab with no vapour barrier underneath keeps releasing moisture, which rules out solid hardwood and makes carpet a genuine mould risk without a vapour retarder first. See our flooring options, pair the job with a basement renovation, or browse what else we build across our Hamilton service area.
We cover flooring in Oakville and floor installation in St. Catharines as well.
The amalgamated communities each bring their own version of this. Century deflection in the old village above the brow is the subject of flooring in Ancaster, and out in the former Flamborough township the recurring problem is moisture from unserviced basements, covered on hardwood flooring in Waterdown.
