Can flexible duct be used in the basement? Does it meet the building code for ontario? Some of the current ducts in my basement are not where I would want them and would affect the ceiling when I decide to finish the basement.
It meets code down here in San Diego, but I would just call your local building or permit department. That should be your most definitive answer.
My constant project is my home which was built in 1947. We have remodeled almost all of it and added 1000 square foot in 2007. Lars Construction got me up to drywall and I did the rest.
