Victoria hardwood: which species is under your floor, and whether it can be refinished

Victoria hardwood is usually one of two woods: old-growth Douglas fir in the character homes built before about 1950, or oak in the post-war and newer builds. Which one you have decides the whole job, because fir is roughly half as hard as oak and leaves far less wood to sand away. We refinish both across Greater Victoria, and identifying the species is the first thing that happens on a quote visit.

Species is not trivia. It sets how many times a floor can be sanded in its life, how evenly it takes stain, how much dust the job makes, and whether the honest answer is a light recoat instead of a full sand-back.

Fir or oak, and why the gap between them is large

Douglas fir boards tend to be narrow, long, and clear, with tight straight grain running almost dead parallel down the board, and they age to a warm orange amber under old finish. Oak shows an open flecked grain with visible pores and takes stain far more evenly. There is a quick field test: press a coin edge into an inconspicuous spot. If it dents under light thumb pressure, you are almost certainly standing on fir.

The Janka test measures how much force it takes to press a steel ball halfway into a board, and it is the number that tells you how much abuse a floor tolerates. Douglas fir rates 620 lb (Wood Database). Red oak rates 1,220 lb (Wood Database), close to twice the resistance to the same dent.

That gap explains most of what goes wrong on older floors around the region. Fir dents under furniture legs and dog claws that oak shrugs off, and it sands fast, so an aggressive pass with a drum sander can cut through the wear layer before the operator hears the machine change note. The same grit sequence that is routine on oak is too coarse to start with on fir.

Humidity moves these floors more than foot traffic does

Wood takes on and gives off moisture with the air around it, so one floor can lie flat in one season, cup at the edges in the next, and open thin gaps between the boards later. Health Canada's guidance for homes is to hold indoor relative humidity between 30% and 50% (Health Canada). Floors that swing well outside that band are the ones that cup, and a damp crawlspace under an older house will do it from below without anything ever being spilled on top.

This matters before a refinish, not after. Sanding and coating a floor while it is cupped locks the cupping in, and once the boards dry out and flatten, the fresh finish sits on a floor with new edge gaps. The moisture source gets dealt with first, the floor gets time to settle, then it gets sanded.

What sanding a floor actually puts in the air

Sanding is the part of refinishing that fills a house with fine dust, and that dust is a real exposure rather than a nuisance. The International Agency for Research on Cancer classifies wood dust as a Group 1 human carcinogen (CCOHS). Hardwoods such as oak generally produce more dust than softwoods worked in similar conditions, and dry wood produces more than damp.

Practically, that is the argument for real dust containment and for staying out of the house while the sanding runs, whether the work is ours or your own. If you are renting a drum sander for the weekend, a shop vacuum and an open window are not containment, and the dust will settle into every connected room for days afterward.

Matching the fix to the floor you have

• Dull and lightly scratched, with sound wood underneath and even colour: a recoat is enough. On fir it is often the better call anyway, because it spends none of the wood you have left.
• Bare wood in the traffic paths, dark stains, or gouges into the timber: the floor needs a full sand-back and refinish, with a stain choice made on test patches of your own boards.
• A handful of damaged boards, a burst pipe, or a pet-stained corner: board repair or water-damage restoration brings the floor back to one surface before any finish goes down.

A fir floor that has already been sanded once or twice may not have enough timber left above the tongue for another pass, and that is a measurement question rather than a guess. We check board thickness and the remaining wear layer before recommending a sand-back on any older floor. Homeowners in Victoria and the surrounding communities can book a free in-home look.

Frequently Asked Questions

How do I tell whether my floor is fir or oak? Look at the grain and the colour. Fir runs tight, straight, and orange amber; oak is open and flecked with visible pores. Fir also dents far more easily, which is the fastest field test in an inconspicuous corner.

Can old-growth Douglas fir be refinished? Usually yes, and it comes up beautifully. It needs a lighter hand than oak, a finer grit to start, and an operator who knows the wood sands quickly.

How many times can a hardwood floor be refinished? That depends on the timber left above the tongue, not on the age of the house. A floor that has been through two sand-backs already may only have room for a screen and recoat.

Do gaps between the boards mean the floor is ruined? No. Seasonal gaps open and close with indoor humidity. Filling them at the widest point of the year is usually a mistake, because the boards swell again and squeeze the filler back out.

Is refinishing worth it compared with replacing the floor? On old-growth fir it usually is. That grade of timber is not available new, so replacement means losing a board you cannot buy back.
