Landlords in Amersham on the Hill 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.
Commercial work in Amersham on the Hill is priced from a site visit or your drawings. Kitchen extract cleaning, LEV testing and servicing visits are priced per system.
Loft or wall units that gently push filtered air into the home to tackle condensation.
Bathroom, kitchen and utility fans sized to the Part F rates, ducted outside and tested.
We find why the house is wet and fix the ventilation, rather than painting over mould.
