How to Look

at a House

A blog with answers
to your questions about


  1. Perceived as less hurricane-resistant than concrete block - Both wood frame and concrete block homes have to meet the same building code standards for storm resistance, and wood frame homes have been required for about the past 40 years to use extensive metal connectors at top and bottom of the wall, along with “shear wall” reinforcement at corners, to make the walls stronger. But concrete block homes have a long-standing reputation as a better home in a hurricane, even if it is no longer accurate. The Florida Building Code’s enforcement of a “continuous load path” from the ground to the roof of a home has improved the storm resistance of both types of construction. See our blog post “What is a continuous load path?” to read more about it.

  2. Less termite resistant - Wood frame homes have more wood closer to the ground, so they are more likely to have termite problem. Advances in termite prevention, like bait traps, make both types of construction safer from termites nowadays. To find out more, see our blog post “What are the green plastic discs in the ground around the house?”

  3. Less resistant to moisture intrusion problems - The exterior sheathing of wood frame homes is wrapped with a moisture-resistant sheet which is carefully taped around all openings. But when water finds its way into a wood wall it does much more damage than at a masonry wall.



  1. More termite resistant - Termites don’t eat concrete, so the block wall itself is immune to damage, but the wood furring strips running up the interior of the wall as nailers for drywall and the wood baseboard at the floor are fair game for termites to start working their way up the wall. The foundation type of older concrete block homes actually makes them more vulnerable to termites than wood frame. See our blog post “How do termites get into a concrete block house?” for more on this.

  2. More forgiving of moisture intrusion - Block walls have the ability to absorb small amounts of water that get through the stucco, and dissipate it through evaporation over time without causing any damage to the interior.

  3. Impact resistant - Many of the types of siding that are applied to a wood frame wall, including EIFS, are impact resistant but will be pock-marked at the impacted area. Stucco over block does not have that problem.


  1. Slower and more expensive - A block wall is more labor-intensive to build.

  2. Not as energy efficient - It is difficult to provide a level of insulation in a block wall comparable to a wood frame wall. But block offers a secondary advantage, because of its thermal mass, which absorbs heat during the day and releases it at night. This buffer can smooth out heat transmission through the wall between day and night.

    Many homebuyers automatically assume that a home with stucco exterior walls is concrete block, but they will be wrong about half of the time. Both block and wood frame homes can have a stucco wall finish and, to find out how to tell which type of wall is under the stucco, see our blog post “How can I tell if the exterior walls of a house are concrete block or wood or brick?”

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
