FAQ Q: What types of windows are best suited for homes in Honolulu? A: In Honolulu, impact-resistant and energy-efficient windows are highly recommended due to hurricane exposure and intense sunlight. Low-E glass coatings help reduce solar heat gain, keeping homes cooler without relying heavily on air conditioning. Q: How often should windows be inspected in Hawaii's coastal climate? A: Coastal homes in Hawaii should have windows inspected annually for salt corrosion, seal deterioration, and frame damage. The combination of salt air and humidity accelerates wear on standard window materials. Q: Does window installation in Honolulu require a permit? A: In most cases, replacing windows in Hawaii requires a building permit if the opening size changes or if structural modifications are made. A licensed contractor can help navigate permit requirements for your specific project.
