Can scratched hardwood floors be repaired without full sanding in NB?

Yes, many scratches on hardwood floors can be repaired without a full sand-and-refinish, but the repair method depends entirely on the depth of the damage — whether the scratch is in the finish layer only, into the stain, or deep into the wood grain itself.

Surface scratches that affect only the polyurethane or finish layer are the easiest to address. These appear as fine white or light lines that are visible in certain lighting but do not catch your fingernail when you run it across them. For these, a hardwood floor polish or refresher product (such as Bona Hardwood Floor Polish or Rejuvenate) fills the micro-scratches and restores the sheen. This is a straightforward DIY project — clean the floor thoroughly, apply the product with a flat mop, and let it dry. The results are temporary (3-6 months) but effective for maintaining appearance between professional refinishing cycles.

For scratches that have penetrated through the finish into the stain layer — showing as lines of lighter or darker wood — touch-up markers and stain pens are the go-to repair. Minwax, Varathane, and Old Masters all make colour-matched wood stain markers that you apply directly into the scratch, wipe away the excess, and seal with a thin coat of matching polyurethane. Getting the colour match right takes patience and testing on an inconspicuous area first.

Deeper scratches and gouges that penetrate into the wood grain require wood filler. Choose a colour-matched wood filler (not generic wood putty, which does not take stain), press it into the gouge with a putty knife, let it dry, sand flush with 220-grit sandpaper, and apply matching stain and polyurethane. This works well for isolated damage but is noticeable on close inspection in most cases.

For homes in New Brunswick where scratches are widespread across a room — common in entryways and kitchens after a harsh winter of tracked-in grit and road salt — a screen and recoat is the most effective repair short of full refinishing. A floor professional lightly abrades the entire finish surface with a floor buffer and screening pad, then applies a fresh coat of polyurethane. This hides minor surface scratches, evens out the sheen, and adds a new protective layer. In NB, expect to pay $2-$3 per square foot for this service — significantly less than the $3-$6 per square foot for a full sand-and-refinish.

New Brunswick's Maritime climate adds a complication: winter drying shrinks hardwood planks, opening gaps where grit and debris settle between boards. When the wood expands again in summer, that trapped debris acts like sandpaper on the finish. Preventing scratches is far more effective than repairing them. Keep indoor humidity between 35-55% year-round, use felt pads under all furniture legs (check and replace them every 6 months), place quality doormats at every exterior entrance to catch salt and grit, and avoid walking on hardwood in outdoor boots during winter.

For isolated scratches, DIY repair is perfectly reasonable and costs under $30 in materials. For widespread finish wear or deep scratches across large areas, hire a professional flooring contractor — a screen and recoat is a cost-effective middle ground that restores the floor's appearance without the dust, disruption, and expense of a full refinish.
