Finally, maintaining the beauty and functionality of window and door fittings is essential for their longevity. Homeowners should look for fittings made from durable materials that are resistant to rust, corrosion, and wear. Regular maintenance, including cleaning and lubrication, can help prevent potential issues and prolong the life of fittings. Choosing easy-to-maintain finishes, such as powder-coated or anodized surfaces, can also help reduce upkeep requirements.
