Landlords in Newtown can book a whole-property check: fans tested, trickle vents looked at and a written list of what to fix, which is useful evidence if a tenant reports damp or mould.
For businesses in Newtown we cover office and shop ventilation, commercial kitchen extraction, duct cleaning to TR19 and planned servicing of air handling units.
