Situation: Attached 2-story, 20-year-old condo buildings located in south central Indiana (Bloomington), with 4 connected first floor units above approx. 1000 sq ft. vented crawl spaces approx 24" h. The crawl spaces are connected in pairs. A year ago we shared our pre-buy inspection report with the HOA. The main crawl space issues were that a lot of fiberglass insulation was hanging down and the vents needed to be repaired or replaced. I assumed they would clean the place up and replace any batts that needed it. Instead, the HOA board contracted to have the spaces "conditioned" without seeming to understand the complexity of this particular situation. I raised questions with them. Eventually, I got an agent in the city Planning Dept involved, and he pointed out design problems and requirements for fire retardant barriers, dampers, etc. Unfortunately, by the time they paused in the process to reconsider their approach, the contractor had removed all the fiberglass insulation, installed a new vapor barrier (and probably removed the old one) and installed 2" rigid extruded polystyrene insulation on the exterior walls. The city agent suggested 4 possible options. The simplest and probably least costly seemed to be that of sticking with the vented system. The board agreed, but informed me that they would use spray foam instead of batts. Sounds nice, but... Possible problems that I see are: * The HOA board seems reluctant to communicate with residents living over the crawl spaces (to determine or alert re allergy/health issues, precautions during application, etc.) In a situation such as this, what info or precautions are residents typically given re application day and afterward? * I read on another site that 2" deep spray foam might cost $2 sq ft. x 100 sq ft @ = $8k. The board has not said what the actual quoted price is. Does this sound accurate? And would that include the required fire barrier? * Perhaps more to the point - can a thorough job can be done, applying this spray to a surface about 24" above the floor while lying down in an unlighted crawlspace? I'd appreciate any feedback/opinions on proceeding from here.
