Properly finished iron doors handle New Jersey’s climate better than most materials. The key is using appropriate primers, base coats, and topcoats designed for exterior iron applications in humid, variable climates.Our finishing process includes rust-preventive treatments and weather-resistant coatings that protect against moisture, salt air, and temperature fluctuations. Regular maintenance involves simple cleaning and occasional touch-ups, not major refinishing projects.Iron doors actually expand and contract less than wood doors, which means fewer gaps, better weatherproofing, and more consistent operation year-round. The thermal mass also helps with energy efficiency—iron doors don’t transfer heat and cold as readily as hollow metal alternatives.
