Flooring choice gets discussed as an aesthetic decision and it is mostly a technical one. The two questions that actually determine what you can install are what is underneath and how much moisture the space sees. Get those right and most materials will perform; get them wrong and no material will.
The subfloor is where flooring projects succeed or fail. Deflection, flatness and moisture content all have to be within the tolerance the finish material requires, and every manufacturer warranty depends on it.
Match the material to the substrate
Over a basement or crawlspace with a wood subfloor and no moisture issue, solid hardwood is viable and will last generations. It needs three to seven days of acclimation on site and correct expansion gaps at the perimeter.
Over a concrete slab, solid hardwood is a poor choice. Engineered wood, luxury vinyl plank or tile are the sound options, with a vapour barrier in all cases. Moisture moves up through slabs continuously even when they appear dry.
Below grade, luxury vinyl plank is the practical default. It is fully waterproof, dimensionally stable, and tolerates the humidity swing of a basement. Tile is the other good option. Solid wood should not go below grade at all.
In wet rooms, tile or luxury vinyl. Nothing with a wood core, including engineered wood and most laminate.
What moves the price
- Subfloor condition. Levelling, deflection correction and moisture remediation are all additional to the flooring itself and all are sometimes necessary.
- Material. Luxury vinyl $6 to $12 installed, engineered wood $9 to $18, solid hardwood $12 to $25 with finishing, tile $14 to $30.
- Removal and disposal. Removing tile set in a mortar bed, common in older homes here, is substantially more work than removing a floating floor.
- Transitions and trim. Reducers, thresholds, stair nosings and shoe moulding are priced separately and are where an installation looks finished or unfinished.
Mistakes we see most often
- Installing solid hardwood without acclimating it on site. In this climate that produces gapping in January and cupping in August.
- Laying anything over a slab without a vapour barrier.
- Skipping subfloor flattening before large format tile, which will lippage visibly.
- Running flooring tight to the wall with no expansion gap. Wood and vinyl both move, and a floor with nowhere to go will buckle.
What this means in the Capital Region
The Capital Region humidity swing is the thing to design around. Indoor relative humidity here can run above 60 percent in August and below 25 percent in January with the heating on. Solid wood responds to that by moving, and the only ways to manage it are correct acclimation, correct expansion gaps, and ideally some humidity control in winter.
For basements, which are extremely common in housing here, luxury vinyl plank is the answer in the great majority of cases. It removes the moisture and movement questions entirely, and modern products look considerably better than their reputation suggests.

Frequently asked questions
What flooring is best over a concrete slab?
Engineered wood, luxury vinyl plank or tile, always with a vapour barrier. Solid hardwood over a slab is a poor choice because slabs move moisture continuously.
How long does flooring need to acclimate?
Solid hardwood needs three to seven days in the space it will be installed in, at normal living conditions. Skipping it is the single most common cause of gapping and cupping in this climate.
Can I install flooring over existing tile?
Sometimes, if the tile is sound, well bonded and the added height does not foul doors or appliance openings. Removing it is usually the better answer, particularly if it is set in a mortar bed.
Is luxury vinyl plank any good?
Yes, and it has improved enormously. It is fully waterproof, dimensionally stable, and the right answer for basements, mudrooms and busy family spaces. Quality varies considerably, and wear layer thickness is the number that matters.
