Homes, rentals and business premises in Batchworth and HA6, WD3 and WD18.
We cover Batchworth (HA6, WD3 and WD18) as part of our work across Hertfordshire. We can help homeowners, landlords and businesses with new systems, testing, cleaning and repairs.
Landlords in Batchworth 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 Batchworth 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.
Tested fans and PIV for rental homes and HMOs, with records for your property file.
