I'm doing a few DIY jobs for some friends and one of the jobs they have asked me to look at will involve cutting into and/or working around the exterior cladding material of their basement garage (specifically, replacing an existing window frame with a new one). Their house is approx 1950's vintage and the basement cladding is a sheet material along the lines of the old Fibrolite product.
I'm concerned that whatever this material is, it may have asbestos in it - in which case I will stay well clear of working it.
Is there any way of determining whether the material contains asbestos? Are there people who can test it for us?
TIA.
