Pairing James Hardie Iron Gray Siding

A key design tip when using James Hardie’s Iron Gray siding is to pair it with complementary colors. Try to avoid matching it with too many other gray tones. Here are some colors that work well with Iron Gray:

Warm Neutrals

  • Almond – soft beige with yellow undertones
  • Brown – choose a warmer shade like chocolate or chestnut
  • Sandstone – earthy light brown
  • Khaki – subtle greenish tan

Cool Neutrals

  • White – bright, clean contrast
  • Light gray – add visual interest by varying shades
  • Charcoal – deepen and enrich the gray
  • Black – strong, bold accent

Natural Hues

  • Green – mossy, sage, or olive tones
  • Blue – lighter sky blue or navy
  • Wood tones – natural cedar or reddish brown

Incorporating colors like these will make the Iron Gray pop while still ensuring everything works together cohesively. Use trim, shutters, and other accents to provide contrasting or complementary hues.

Using Iron Gray for a Whole House

While Iron Gray works great as an accent, can it be used on the entire exterior? Absolutely! Here are some tips for using Iron Gray house-wide:

  • Add visual interest by incorporating different siding styles and textures. Try a combo of lap siding, vertical siding, and board-and-batten.
  • Use lighter shades of gray or off-white for trim and corner boards to frame windows and doors
  • Paint the front door a bold, contrasting shade like red, blue, or black
  • Use natural stone veneer as an accent for the home’s foundation
  • Plant colorful flowers like purple asters or red tulips to make the landscaping pop

The varied textures and strategic use of accent colors will keep an all-over Iron Gray exterior from feeling flat or monotonous. This on-trend gray shade makes a striking statement on its own.

Maintenance for Iron Gray Siding

James Hardie siding with ColorPlus Technology has a 15-year fade resistant warranty. However, periodic cleaning and maintenance is still a good idea.

Here are some tips for keeping Iron Gray siding looking its best:

  • Wash occasionally with a garden hose and mild non-abrasive soap. Avoid high pressure power washing.
  • For stains, spot clean by hand with baking soda paste or diluted vinegar solution.
  • Check for damage and repair as needed with touch-up paint.
  • Caulk gaps around trim, windows, and doors to prevent water intrusion.
  • Repaint every 8-12 years or when fading/chalking occurs.
