Under the covers

This is a project at a high end hotel in Raleigh NC where We completed repairs in multiple rooms where mildew growth was forming under cover of vinyl wall covering

This picture shows the mildew growth behind the wallcovering

 

 

 

This picture shows the wall as we begin to remove the damaged gypsum panels, this wall is a concrete wall that has drywall glued and nailed to it, and concrete by nature absorbs moisture which in humid conditions can promote mildew growth.

This picture shows the wall after we began to demo the drywall panels, notice the mildew growing on the back side of the opposing room’s wall.The opposing wall was treated with mildewcide to try and eliminate any further growth

Mold & Mildew

This is from a project we completed at a high end hotel near the Crabtree Valley area of Raleigh NC

These pictures show a window wall with water damage caused by an exterior facade leak. The moisture penetrated the wall cavity over a period of time, allowing mildew and mold to grow within the wall; this eventually penetrated the drywall and began to loosen the wallcovering

This mildew continues down the walls from the window walls growing virtually undetectably behind the vinyl wallcovering

This is a close up picture of the mildew/mold growth growing on the face of the drywall

This picture shows how we begin remediation,once the exterior leak was properly addressed, we remove all damaged vinyl, drywall and insulation, pack the contaminated materials into black sealed bags and then discreetly removed them from the hotel. We repaired any damaged framing, treated the studs and opposing walls with a bleach solution to help prevent future mildew growth. We then replaced the insulation, install new mold resistant gypsum panels, after the drywall has been finished we treated all new walls with a low VOC primer with a mildewcide additive. Once the walls are complete and ready for wallcovering we install new vinyl yard goods, the wallcovering  adhesive we use is a heavy duty, clear, strippable paste which also has a mildewcide additive. These mildewcide additives are used to help restrict and new mildew/mold growth.
