The cost of painting the exterior of a house NZ depends on factors like house size, paint quality, and surface preparation. Typically, prices range from $4,000 to $10,000 for a standard home. While summer is the most popular season for painting, exterior painting in winter NZ can also be effective with the right conditions and professional painters. Winter painting requires careful planning, using weather-appropriate paints, and choosing dry, mild days. Hiring experienced contractors ensures a durable finish that withstands New Zealand's climate, no matter the season. A well-painted exterior not only protects but also adds value to your home.
