Destructive Testing Reveals The Reason Why The Stucco Soffit is Cracking

A client of William Leys Waterproofing Consultants LLC has a problem with stucco under their balconies. The stucco is cracking on the outside edge of the soffit (the ceiling under the deck). Several residents were reporting that when it rained water would come out of the cracks.

The Board of Directors sought a waterproofing consultant to assist in finding out why their stucco was cracking and leaking water. They thought the source of the water intrusion was from the decks. After a search they found us and retained us to perform some destructive testing and investigate the source and reason for the cracking.

We started by making visual observations of the decks and surrounding building materials. We observed the cracked stucco under the soffits, we observed the decks and we observed the exterior walls of the balcony and the walls adjacent to the balcony.

Cracked stucco soffit and water stains.
Architectural styrofoam bullnose detail is cracking where it meets the wall. Note the efflorescence on the wall below.

Our observations found the soffits were indeed cracked and stained from water. We observed that the exterior walls surrounding the balconies also had cracks, and that a foam architectural bullnose detail was cracking where it joined the wall.

Firing up our grinder with a diamond blade to cut through the stucco, we found rusted stucco diamond lath. Stucco lath gives the stucco something to grip to.

Rusted lath under the stucco affirms water is leaking into the soffit, but from where?

We peeled back more stucco, exposing the structural beam at the outside edge. The beam had no damage to it at the two locations we opened.

Nice and dry and free of any signs of water intrusion.

Next we opened up the foam bullnose on the wall surrounding the deck. Here we found the apparent problem. The stucco behind the bullnose has large cracks in it. In the corner we found a large hole in the stucco with rotted wood behind it.

Behind the foam bullnose, a large crack exists.
Our 6″ long awl meets no resistance where wood framing should be.

Pending further destructive testing by a contractor, our initial conclusion is that the foam bullnose and cracked stucco behind it is the source of the water getting into the stucco soffits of the balconies. Now we just need to follow the waters path down the building and see if structural damage is occurring inside the walls.

Why You Need Quality Assurance Observers on Site During Waterproofing & WRB Installations

What is the total cost of having to fix construction defects that you found after the building is completed? When tenants are ready to do their tenant improvements, move in and start paying rent, but can’t because of water leaks, how much does unnecessary delays cost? How much does it cost to put up scaffold around a building, remove the brick facade, redo all the windows flashings and then put it all back together? How much in lost rents did this cost? $250,000? $1,000,000? We don’t know the answer to this question but we can take a wild assed guess…a lot!

This building is in downtown San Luis Obispo, and was ready at the end of November for tenant improvements to begin in the interior-a restaurant on the first floor, Amazon offices on upper floors; and then it rained. That’s when the owner of the new building discovered he had a major problem. Many windows leaked in the storm. So they hired a consultant (not us) who performed spray water testing in conformance with ASTM standards for leak testing.

Of the approximate 60 windows in the building, 45 or so leaked. After destructive testing was done, it was discovered that molded corner flashings that are installed into the rough opening of the window frames had a critical piece cut off by someone, and no one noticed or knew…and then the windows were installed, the facade installed and no one did any water testing or quality assurance construction monitoring during the window/WRB installation. ..if they had, the work could have been halted, the issue rectified and the costs and damages could have been greatly mitigated.

Daily costs for Quality Assurance Construction Monitoring run $1,200 a day. On a job like this building, maybe 30 days of construction monitoring may be necessary, or about $36,000.00. Which sounds like a lot until you go back to the costs of lost rents, building repairs and the headache of months of delays in getting your building back.

Quality Assurance Observations don’t cost, they pay with long term dividends on a properly dried in building. That’s what we do-help make buildings perform better, one building at a time.

Call us today for a discussion on how William Leys Waterproofing Consultants LLC can help you with quality assurance construction monitoring, where we observe, inspect, document and report to you, the building owner or general contractor, what we have observed, materials used, whether the work was done according to plans, specifications and the drawings.
