4 Most Common Adhered Stone Veneer Problems


4 Most Common Adhered Stone Veneer Problems

If you have stone veneer on your home’s exterior, there are four common problems you should be aware of and keep a lookout for. While these problems are not extremely common with stone veneer in general, if there are any shortcuts or errors made during installation, these are the most common problems you can expect.

If you think your stone veneer is showing any signs of damage or malfunction, we strongly recommend getting a professional inspection. ESEC provides stone veneer inspections throughout Denver and across the Colorado Front Range.

1. Leaks

Even in places like Denver with a semi-arid climate, water leaking and damaging the home’s interior is possible—we have seen it firsthand. Stone veneer needs a Weather Resistive Barrier (WRB) and drainage plane with a drainage provision installed beneath it to protect your home. Failure to do so can result in leaks and moisture damage inside, including mold, wood rot, and signs of moisture on the interior of the walls. These issues can be very expensive to fix and should be addressed as soon as possible.

2. Vent Problems

Every home has exterior vents that connect to exhaust fans, the dryer, and kitchen hood. For all homes the vents should be installed against a bed of sealant, a flexible, silicone caulk that seals the vents against the home. With adhered stone veneer, these vents are often installed directly into the mortar. Because mortar is not flexible, any home settling or movement or thermal movement can break the vent loose from mortar allowing moisture intrusion and/or pest intrusion.

3. Leaking Windows and Doors

Just like vents, your home’s windows and doors are another place where poor installation can cause serious damage to your home. For years the adhered stone veneer manufacturers specified grout or mortar to seal the joint between the window or door and the adhered stone veneer. The grout or mortar are porous and fail over time. Current installation details call for backer rod and sealant. Get an inspection immediately if you see water damage inside the home or stone that is taking much longer to dry next to windows and doors.

4. Kickout or Diverter Flashings

One place that should always be checked is below gutters where they meet a taller house wall. If there is staining or damage on the stones or ground below the gutters it is time for a stone inspection.

In no way do we want to discourage you from choosing stone veneer for your home’s siding—a many homes have no stone veneer issues because of the professional and thorough installation. But, if you are purchasing or living in a home with stone veneer and you see any issue listed above, we strongly recommend getting a professional inspection. An inspection now could save you from further damage or even save you some money on a home purchase.
