How much does floor sanding cost?
There's no honest per-square-metre answer because every floor is different. Condition, timber species, number of coats, coating type, access, stairs -- all change the price. Get at least two quotes from local contractors. If one is way cheaper than the rest, ask why. Don't just go with the cheapest. Find someone you're comfortable with, read their reviews, check their previous work, and shop local.
Is it cheaper to sand or replace timber floors?
Sanding is almost always cheaper. A full sand and three coats on an existing floor costs a fraction of ripping it up and laying new timber. The only time replacement makes sense is when the boards are structurally gone -- rotten, split through, or so thin from previous sands that there's nothing left to work with.
How much does stair sanding cost?
Stairs cost more per step than floors cost per square metre. Every tread and riser is a separate surface, the edges are exposed, and it's slow, fiddly work. Get a specific quote for stairs -- don't let someone roll it into the floor price without breaking it out.
Why is water-based finish more expensive than solvent?
The product costs more, the application needs more care, and the contractor needs better equipment (dust extraction especially). But it lasts longer, doesn't yellow, dries faster so the job finishes sooner, and you don't have to leave the house for three days. The upfront cost difference usually pays for itself.
Does floor sanding add value to a house?
Yes. A properly finished timber floor is one of the first things buyers notice. It's one of the cheapest renovations relative to the value it adds. Even a maintenance recoat before selling can make a big difference.
