In this guide we discuss Hardie Board vs. Stucco including what Hardie Board is & how it compares to stucco siding.
When homeowners decide to replace the siding on their home, or if purchasing a new build, they have many siding options to choose from. Two of those options with durability and long life are Hardie Board and Stucco.

What is Hardie Board?
Fiber cement is a form of cement mixed with 8 to 10% wood fiber and either fly ash or silica sand giving it extra durability and allowing the product to dry flexible, somewhat similar to synthetic stucco. Hardie board lasts for years and requires little maintenance.
Hardie comes in several forms used for exterior siding including:
• Hardie lap siding
• Hardie long boards
• Hardie panels similar to vertical board and batten
• Hardie shingles
This versatile product has a characteristic hard to match—bugs such as termites hate it and can’t do damage to it, and Hardie board is water-resistant.
What is Stucco?
Typically layered, stucco creates a strong surface with fire retardant properties and lasts anywhere from 50 to 80 years. Stucco is susceptible to moisture damage and cracking, requiring regular maintenance.
Which is Better, Hardie Board vs Stucco?
Another great factor about fiber cement is the ability to paint or repaint it with alkali paint to freshen it up or change the color.
Stucco is also a great choice for siding, offering the same durability and long-lasting life as Hardie board, but stucco is very susceptible to moisture and bug damage.
When considering Hardie Board vs stucco its important to consider your home’s location. Stucco performs well in dry weather conditions, however areas of extreme humidity or rainfall may cause a stucco exterior to crack.
Unlike Hardie board products, stucco requires more maintenance, and painting stucco means surface preparation that could be extensive.
Stucco has fire retardant properties, as does Hardie board, both slowing down the spread of fire from the outside by almost an hour, giving the occupants time to get out.
Cost of Hardie Board vs Stucco
Costs vary between locations around the country and the climate but do not change greatly. Other types of Hardie, such as Hardie lap board or Hardie shingles, will cost more or less than Hardie boards.
A home with 1200 square feet of exterior wall that needs siding would cost $12,000 installed with Hardie boards or $8,400 for stucco.
Hardie board siding runs a bit less than stucco siding, and both provide premier siding with durable resilience but Hardie board is much more resistant to moisture damage from the elements.

Can You Put Hardie Board Over Stucco?
The benefit of removing stucco will reveal rot, mold, bug and termite damage, and water infiltration. The cost of repair may be more or less expensive than complete removal. The age and type of stucco also affect whether to remove the stucco or not.
If existing stucco doesn’t need to be removed, bulging or warped areas need to be flattened to allow for a level surface. The stucco siding will need furring strips installed every 15 inches to fasten the Hardie board on.
It’s recommended to install closed-cell foam boards between the furring strips to provide packing in case the siding is bumped. The uneven space between the furring strips may allow cracking. Only a professional should do the installation of Hardie board over stucco.
