We just had the crawl space sealed. All new vapor barrier, all entry and exit points totally sealed. This included putting heavy gauge wire on all vents. What impressed me was the technician said to me, ‘I saw where you put steel wool around the pipe going through your floor to the kitchen sink’. I asked why he found it. He said that it’s all part to the service sir, EVERYTHING going through your floor is also now sealed. Truly great service done professionally by very polite technicians.
