How we work through an Okotoks gapping problem
Measure the gaps, in season
Record where the gaps are, how wide, and whether they run through the whole floor or cluster near heat sources and exterior walls.
Read the room, not the floor
Put a hygrometer in the room and track relative humidity through the heating season. A single reading on one day tells you very little.
Decide what is seasonal
Gaps that close again by late summer are the floor breathing. Gaps that stay open all year are a different problem and get treated differently.
Act in the right season
Filling or refinishing is scheduled when the boards are at their widest, so the work is not undone by the next humid spell.
Okotoks hardwood planning ranges
Planning ranges in Canadian dollars, for budgeting only. These are not quotes and not offers.
Hardwood installation
$6-15 per sq ft
Planning range for a new hardwood floor. Species, board width, layout, subfloor condition and stair work all move the figure within and sometimes beyond this band.
Refinishing
$3-7 per sq ft
Planning range for sanding back and refinishing an existing floor with enough wear layer left to take it. Priced only after the floor has been seen.
Furniture handling
$200-600 flat
Planning range for moving and returning furniture where the rooms cannot be cleared before work starts.

Reading a gap in an Okotoks hardwood floor
Okotoks, with a recorded population of 33,482, sits south of Calgary in the foothills, in the same chinook belt as the city. Every winter that produces the same phone call: thin dark lines have opened between the boards of a hardwood floor that was fine in September.
In most cases nothing has failed. Heated indoor air in an Alberta winter is dry. Relative humidity inside a heated home here routinely falls under thirty per cent, below Health Canada's winter guidance of roughly thirty to thirty-five per cent, and well below the thirty-five to fifty-five per cent band the National Wood Flooring Association associates with dimensional stability. Wood gives up moisture to dry air and shrinks slightly across the width of each board. That shrinkage has to appear somewhere, and it appears at the joints.
What tells you which kind of gap you have is not the width. It is the calendar. A gap that narrows through spring and has largely closed by late summer is a floor doing what wood does. A gap that measures the same in August as it did in February is telling you something else: a fastening problem, a subfloor issue, or a floor that was installed too wet and has been shrinking ever since.
What actually moves the number back
If seasonal gapping bothers you, the useful lever is the room rather than the floor. Raising winter indoor humidity toward the low thirties reduces how far the boards shrink in the first place. A whole-home humidifier on the furnace does this most consistently; portable units help a single room.
There is a ceiling on it. In a cold climate, pushing indoor humidity too high moves the problem into the building envelope, where it shows up as condensation on windows and moisture in wall cavities. The goal is a stable, moderate humidity through the heating season, not the highest number the equipment can reach.
The other lever is decided before installation. Narrower boards divide the same total seasonal movement among more joints, so no single gap gets wide enough to notice. Engineered construction moves less across its width than solid wood of the same width. Neither choice eliminates the cycle, and neither should be sold as if it does.
When a gap becomes a repair
There is a point where seasonal explanation stops being useful. Boards that have cupped or crowned rather than simply parted, gaps with a height difference between the two sides, movement underfoot, or a joint you can feel with a fingernail all year; those are conditions to look at properly rather than wait out.
Filling is the intervention that most often goes wrong. Filler pressed into a joint at its widest, in the depth of winter, gets crushed when the board expands again, and worse, it can lock two boards together so the following season's movement opens a gap somewhere it was not before. Where filling is right at all, it belongs to year-round gaps and to the season when the boards are at their widest.
Okotoks hardwood and humidity questions
Why did gaps appear in my floor over the winter?
Because heated air in an Alberta winter is dry, and wood gives up moisture to it. Indoor relative humidity in a heated home here routinely falls under thirty per cent, which is below Health Canada's winter guidance of roughly thirty to thirty-five per cent and well below the thirty-five to fifty-five per cent band the National Wood Flooring Association associates with dimensional stability. The boards shrink slightly and the shrinkage shows up at the joints.
Will the gaps close again?
Seasonal gaps usually narrow through spring and summer as indoor humidity comes back up. That is the test we use. If a gap is still exactly as wide in August as it was in February, it is not seasonal movement and it needs to be looked at as a fastening, subfloor or installation question instead.
Should I fill the gaps?
Rarely, and never while they are at their widest. Filler forced into a joint in February gets crushed or pushed out when the board swells back in July, and it can bond adjacent boards together so the next season's movement lands somewhere worse. Persistent, year-round gaps are the ones worth filling.
Does a whole-home humidifier solve it?
It addresses the cause, which is more than any repair does. Bringing winter indoor humidity up toward the low thirties reduces how far the boards shrink. There is a limit: pushing humidity too high in a cold climate causes condensation on windows and in wall assemblies, so it is a balance rather than a target to maximise.
Can a gapped floor be refinished?
Refinishing changes the surface, not the width of the boards, so it does not close seasonal gaps. It is the right call when the finish is worn through, the floor is scratched or the colour is being changed, and it needs enough wear layer left above the tongue to take a sanding pass.
