The cost of painting the exterior of a house in NZ depends on various factors, including the size of the property, paint quality, and labor charges. While exterior painting is often done during warmer months, exterior painting in winter in NZ is becoming more common thanks to advanced paints designed for colder conditions. Painting in winter can sometimes save on costs, as painters may have more availability. However, it's crucial to hire professionals who understand how to handle the challenges of colder weather. A well-executed paint job in any season ensures your home remains protected and visually appealing.
