18x24 Open House #3 – Coldwell Banker Sign Options Simplified

What questions do agents ask?

What size sign works best for open houses?
Which material should I pick: corrugated, PVC, or aluminum?
What hardware fits different yard types?
Are grommets necessary for my sign?

If you’re buying signs, this clears the confusion quickly.

Why 18x24 inches is the standard size

18x24 inches is the ideal size for open house signs. It’s big enough to be noticed but still easy to handle and install.
It fits all common hardware and complies with most city regulations. Coldwell Banker chooses this size for consistent branding across all listings.

Materials available and when to use them

You have three material options:

• 4mil corrugated plastic: lightweight and budget-friendly, great for short-term or single-event use.

• 3mil PVC: thicker and more durable, suitable for multiple uses over months.

• 3mil aluminum: strongest and weather-resistant, ideal for long-term outdoor use.

Choose based on how long you plan to display the sign and weather exposure.

Hardware choices for different setups

If your sign goes into soft ground, stakes work best. Econo Stakes 10x30 are light and easy for short-term use. Heavy Duty Stakes 10x30 provide extra stability in tougher soils. For concrete, sidewalks, or hard surfaces, Wire A-Frames or A-Frames hold signs securely without needing to pierce the ground.

The role of grommets

Grommets protect your sign’s edges from tearing when hung or tied. If your sign sits inside a frame, you might skip them. For windy areas or hanging signs, top, bottom, or both grommet placements keep signs secure and intact.

Who should order these signs?

These signs are perfect for real estate agents, property managers, and landlords. They make open houses easier to find and attract more visitors by clearly marking the property.

Final tips for choosing your open house sign

Go with 18x24 inches for best visibility and convenience. Pick a material that fits your usage duration and weather conditions. Match hardware to your installation location. Use grommets if your sign will be exposed or hung.
