We have a 25m² unheated garage built in 1995 with concrete walls. They're dusty and stained, some minor cracks. We want fresh white paint before winter storage. No professional experience. Should we hire someone or tackle it ourselves — and what's a realistic budget for labour if we go pro?
✓ Accepted answer
Professional garage wall painting in Groningen typically runs €800–€1,400 for 25m² of concrete, depending on prep work. If walls need light cleaning and filling, add €200–€400. DIY is possible if you're comfortable: primer + paint (€100–€150 in materials), but concrete preps demands proper primer and often two coats. Hidden costs: equipment rental (roller frames, poles), dust control, and mistakes can be pricey to fix. Labour usually dominates the cost. Honestly, for a garage, many homeowners save money doing it themselves — but hire a pro if cracks are deep or you suspect moisture issues (common in unheated Dutch garages).
