Details, Details, Details: Stucco or EIFS on Columns and Pillars

In the last 2 entries I have discussed the importance of deck flashing and that Stucco or EIFS should never be installed on a flat surface. Today I am going to discuss a couple of construction details that typically involves both flashing & the use of Stucco or EIFS on a flat surface: Columns & Pillars.

Columns & Pillars can provide a unique architectural feature for any Stucco or EIFS building. Whether columns are installed to highlight the front entrance or pillars are installed around the property with the fencing, both add beauty and charm but can be a nightmare if not done properly.

Some of the worst substrate/framing damage where Stucco or EIFS has been installed are associated with columns or pillars. As I have explained in other posts, the damage is typically the result of the lack of or improperly installed details, not the actual Stucco or EIFS.

Deck columns are one of the areas that can experience severe moisture intrusion resulting in major substrate/framing damage.  Depending on the deck design, the deck structure will either sit on top of the deck column or tie into the column sides.  Both designs require extensive flashing & sealants to prevent moisture intrusion from occurring.  It is also important to remember that if these areas are not flashed/sealed correctly, it doesn’t matter what type of cladding (brick, siding, stone, ect…) is on the column, all can result in major damage.

The top of columns or pillars are another area where moisture intrusion can occur.  The same construction details must be used as described in my previous post: Details, Details, Details: Flat Surfaces.
