Salty Air Corrosion


Living near the ocean has its perks, but the salty air can be tough on your home. Here are 5 tips to prevent saltwater corrosion:

1. Embrace the power of water:

  • Annual pressure wash: Give your house a good rinse at least once a year. This removes built-up salt before it can corrode surfaces. You can rent a pressure washer or hire a professional, but be sure to use a gentle setting to avoid damaging paint or siding.
  • Frequent hosing down: For exposed elements like balconies, railings, and outdoor furniture, a quick hosing down every few weeks can do wonders. This also helps prevent sand accumulation, which can trap salt and moisture.

2. Be picky about materials:

  • Choose corrosion-resistant siding: Opt for vinyl, fiber cement, or engineered wood siding. These materials hold up much better to salt air than traditional wood or metal. In Hawaii, hardy board is one of the most popular siding options to resist salty-air corrosion.
  • Fiberglass for windows and doors: While more expensive, replacing wood or metal doors and windows with fiberglass offers superior salt resistance and thermal insulation.

3. Maintain a protective barrier:

  • Regular repainting: Apply high-quality exterior paint every 3-5 years. This not only refreshes the look but also provides a fresh layer of protection against the elements. Choose marine-grade paints specifically formulated for harsh coastal environments.
  • Seal all the cracks: Regularly inspect and re-seal any cracks or gaps around windows, doors, and siding. These entry points can allow salt and moisture to infiltrate, leading to hidden corrosion.

4. Minimize metal exposure:

  • Switch out hardware: Replace metal hinges, handles, and other hardware with corrosion-resistant options like stainless steel or galvanized steel.
  • Store outdoor furniture: When not in use, bring metal furniture indoors or cover it with protective tarps. This significantly reduces its exposure to salt and prevents rusting.

5. Keep it clean and dry:

  • Keep windows closed: While enjoying the ocean breeze is tempting, limiting open windows reduces the amount of salty air entering your home, protecting interior surfaces and electronics.
  • Clean windows regularly: Don't let salt build up on windowpanes. Wipe them down with a damp cloth to maintain clarity and prevent corrosion around the frames.

Bonus tip: Consider landscaping strategically: Planting dense shrubs or trees around the windward side of your house can act as a natural barrier, filtering out some of the salt spray before it reaches your home.


By following these tips, you can enjoy the beauty of your beachfront home while minimizing the harmful effects of saltwater corrosion. Remember, prevention is key – proactive maintenance will save you time, money, and headaches in the long run.
