The under slab exaust vent is rusting out on the outside the house. The photo shows the rust is worst at the ground level where there is the most moisture throughout the year.
I'd like advice on the appropriate materials needed to patch the rusted area.
Also, which specialists should I contact if I decide to replace this whole outside unit for me - the HVAC people or the roofers?
Thanks, Stan
