Yorkton's housing mix runs from older character homes with wood siding to newer vinyl builds. The prep before a repaint is different for each, and it is the step that decides whether the coating lasts or fails after one winter. Here is what we do before any paint goes on the siding.

Power wash and let it dry

Siding holds dust, pollen, and chalk from the old finish. We power wash to clean it, then let it dry fully. Coating over dirt and chalk is the most common reason a siding repaint fails early, and it is entirely preventable. On wood siding, we use a pressure that cleans without driving water into the grain.

Scrape and prime bare wood

On older Yorkton homes with wood siding, loose and failing paint gets scraped back to sound edges. Bare wood gets primed for adhesion before any finish goes on. Skipping the priming is how you get a coat that peels in sheets after a freeze-thaw cycle.

Caulk the gaps

Gaps at windows, doors, and trim let water behind the siding. We caulk and seal those before coating, because water intrusion is what rots wood and lifts paint from underneath.

Vinyl goes faster but still needs prep

Newer vinyl siding in Yorkton needs cleaning but not scraping. The coating has to be compatible with vinyl, and we do not paint vinyl darker than the original colour, because dark vinyl absorbs heat and can warp. The prep is lighter, but it is not zero.
