Greater London · England
Homes, rentals and business premises in Sidcup and BR7, DA14 and DA15.
We cover Sidcup (BR7, DA14 and DA15) as part of our work across Greater London. We can help homeowners, landlords and businesses with new systems, testing, cleaning and repairs.
Landlords in Sidcup 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.
Food businesses, offices, workshops and schools in Sidcup each have their own ventilation duties. We explain which ones apply to you and keep the paperwork that proves it.
Supply and extract with heat recovery for offices, shops, clinics and fit-outs.
Canopies, extract fans, make-up air and gas interlocks for cafés and restaurants.
Kitchen extract and ventilation duct cleaning with photo reports for insurers.
Noisy, failed or leaking fans, PIV, MVHR and commercial extract put right.
