Refinishing hardwood floors yourself can save thousands on labor costs. Use NailIt to estimate the exact materials you'll need—sanding equipment, stains, sealers, and protective gear—so you know your total spend before you start.
Estimated DIY materials cost for total materials for 200–400 sq ft — you supply the labor. Prices vary by region and brand.
Across the full range this works out to $1.05–$6.25 per sq ft, depending on material grade and how much waste you plan for.
Here is the arithmetic, so you can redo it with your own numbers: a typical project here is 200–400 sq ft and runs $420–$1,250 in materials. Divide the middle of that cost range by the middle of the area range ($780 ÷ 300 sq ft) and you get $2.60 per sq ft. Measure your own space, multiply, and you have your materials budget.
Materials only — labour is not included. See what a contractor charges below.
This is an advanced project — be honest about your skills, tools, and time before going DIY. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $840–$4,375 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project most homeowners are better off getting quotes — see the gauge above. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.

Yes. For DIY refinishing, you'll rent a drum or orbital floor sander (typically $80–$150/day). This is a material cost, not labor. A hand-sanding-only approach is impractical for most floors.
Oil-based polyurethane is cheaper ($30–$50/gal), slower-drying, and has stronger odor. Water-based is eco-friendly, faster-drying, and more expensive ($50–$80/gal). Both work for DIY; choose based on budget and fume tolerance.
Yes, but it's advanced. Watch tutorials, test on a closet first, and allow extra time. Mistakes (over-sanding, uneven stain) are visible and costly to fix. Budget extra materials for practice and touch-ups.
