Home painting is often seen as just a cosmetic upgrade, but in a city like Mumbai, it’s much more than that. While interior painting improves aesthetics, exterior painting protects the building from rain, humidity, and coastal salt damage, especially in areas like Colaba, Worli, Bandra, and Marine Drive.This blog compares interior vs exterior painting, explains which one should be prioritised, and how professional painting services can deliver long-term results with proper planning.
