Ok
We are doing another air duct cleaning on a job we have done several times before. I have done a video inspection and have found the ducts are developing pin holes (Ducts are below the slab) and letting sand in. Is there a reasonably price duct sealing/recoating system out there I can offer. I have found a couple of choices but the minamum investment is 10K to 15K.
I have several customers in the same situation and a new over head duct system is a option. But I would rather leave as is.

I would suggest, Rayflate Duct Sealing System. Check details from Tyco's website.
