Are you having Dryvit issues?

We specialize in repairing Dryvit ® so we know about people having Dryvit issues. There are home owners and business owners that have experienced problems with their synthetic stucco cladding. Moisture damage is one of the biggest problems when it comes to synthetic stucco. The moisture problems are mostly due to a design problem. The original Exterior Insulation and Finish System was what is known as a barrier system, which means it was a weather barrier. When done right the barrier system worked fairly well as the commercial buildings are designed a little better for the barrier system. The flat roof with a copping works much better with the barrier system than a typical residential design. The major issue with Dryvit is in the residential application when it comes to applying the barrier system, which since about the year 2000 the barrier system has not been used. The new system ‘The Next Generation of EIFS’ has been used after the year 2000. In fact the building codes where changed and now there has to be a moisture barrier over any wood framed structure. There may be a wave of homes built in the 80’s and 90’s that are failing now that need to addressed. The old barrier system when done right still holds up well if it is properly maintained. The problem with the barrier system is that if any moisture penetrated it the water was trapped back behind the system and it eventually starts to rot the wood. When the building codes changed they required a moisture barrier over wood, but we will take that one further and say that when using Synthetic Dryvit Stucco you should use a liquid moisture barrier. The liquid moisture barrier works better than a cloth moisture barrier. We have been doing repairs for over 26 years and we found the liquid barrier is far better than the cloth. When installing the cloth barrier you put tons of holes in it when you staple it to the wood and then again when fastening the foam to the wood. When you use the liquid barrier instead of fastening the foam with mechanical fasteners you apply the foam with a notch trowel which creates channels for moisture to drain. The mechanical fasteners smash the foam to the wood so tight to the wood moisture has no chance to escape. If a liquid moisture barrier is used you can eliminate the biggest issue when it comes to the product. dryvit issues
