How Long Steel Windows Last

Steel windows are highly durable and, when properly maintained, can last 50 to 100 years or more, depending on factors like the quality of the steel and environmental conditions. Galvanized steel, in particular, provides excellent corrosion resistance.

However, without proper care, steel windows may show signs of wear much sooner, sometimes lasting only 10 to 20 years—that’s the difference regular maintenance can make. Read this guide to find out how to maximize the lifespan of your steel windows.

How To Maintain Steel Windows For Maximum Longevity

Clean your steel windows properly every month to maintain their quality.

1. Regular Cleaning

  • Materials Needed: Mild detergent, soft cloths, and clean water.
  • Procedure: Clean the frames and hardware regularly using a mild detergent mixed with warm water. Avoid abrasive cleaners or materials that can scratch the surface.
  • Additional Tips: Use a soft-bristled brush or vacuum to remove dirt from hard-to-reach areas. Dry the frames thoroughly after cleaning to prevent water spots and rust.

2. Inspection and Repair

  • Rust and Corrosion: Regularly inspect your windows for signs of rust or corrosion. Use a wire brush to remove light rust and apply a rust-inhibiting primer. For severe corrosion, sand down to bare metal and repaint.
  • Hardware Maintenance: Lubricate hinges and locks for smooth operation.
  • Weather Stripping: Check and replace weather stripping as needed to maintain airtight seals.

3. Protective Measures

  • Paint and Coatings: Apply touch-up paint to small chips or scratches on the frames. Use high-quality metal primer and paint for larger repairs.

6 Signs Your Steel Windows Need Maintenance

  1. Drafts and Air Leaks: Feeling cold spots or drafts around the windows indicates that the seals are failing and may allow air to escape or enter.
  2. Condensation and Fogging: Excessive condensation between panes or fogging on the glass surfaces suggests that the window's insulation properties are deteriorating.
  3. Difficulty in Operation: If steel windows stick, are hard to open or close, or make creaking noises, it may be a sign that the frames are warping or the hardware is failing.
  4. Rust and Corrosion: Visible rust spots or corrosion on the steel frames indicate that the protective coatings are not up to the mark, which can lead to structural issues.
  5. Peeling Paint or Fading: Fading or peeling paint can expose the metal to the elements and lead to corrosion and further damage.
  6. Increased Energy Bills: Rising heating or cooling costs can indicate that the windows are no longer energy-efficient due to gaps or poor insulation.
