A lot of lying-liar-charlatan-moron-spray-foam contractors in and around the NJ shore are claiming that "*Spray Applied Closed Cell Foam Insulation is the ONLY form of insulation material that is approved and supported by the Federal Emergency Management Agency (FEMA)". This is a lie. FEMA classifies both "Sprayed polyurethane foam (SPUF) or closed-cell plastic foams" as "Acceptable" for floors, walls and […]

Installing some windows on the Upper West Side this week. I call the building ‘The Roosevelt Building’ because FDR the third lives here. Right on Riverside, beautiful! It’s the 4th apartment we’ve installed windows in over an 8 year period. The jamb and trim work will be elaborate, I’ll post more pics later as I do it. We are stripping […]
