I'm looking for a reliable handyman to paint a wooden staircase inside my house. The stairs are currently unfinished and need a smooth, even finish with two coats of primer and topcoat. I prefer a semi-gloss or satin finish in a neutral colour. Work should include light sanding, masking of adjacent areas, and cleanup after painting. I’d like the job to be carried out on a weekday morning, with materials provided or discussed beforehand. Please mention any preparation steps you recommend and an estimated completion time.
