What is Dryvit? Dryvit is most frequently referred to as stucco looking material by homeowners but is actually a composite material that was designed to be insulated and water resistant, while maintaining a “beautiful” exterior appearance. The use of this material in the U.S. started in the 1960’s but boomed in the 70’s. The promise of a water resistant decorative insulation made it a popular exterior choice. Why wouldn’t it?

Like most specialized products, Dryvit only works if installed properly. Dryvit is similar to brick’s installation where there needs to be a gap between your sheeting (underlayment) and the Dryvit to allow the moisture to dry without being up against the wood. Knowledgeable installers could not keep up with the high demand of Dryvit in the 70’s , so unqualified installers stepped in. The majority of those jobs were installed wrong, the Dryvit soaks up the water and retains it against the wooden underlayment, allowing it to rot and get moldy. There is no way to tell the condition of the underlayment without removing the Dryvit- many homeowners are living with severe rot and damage without being aware of it.

We were recently hired on to replace a homeowner’s dryvit exterior with a vinyl product because the homeowner was tired of the “dated look” the dryvit gave their home. When we tore off the Dryvit we found out it was not installed properly and a majority of the underlayment had to be replaced. In the photos, you can see all the black mold on the wood and in some cases the wood no longer exists from years of rotting away.
