Our Story
Trusted Window & Exterior Cleaning in South East London
Blackheath Window Cleaners has been serving homes and businesses across Blackheath, Greenwich and South East London for over 25 years. What started as a local window cleaning round has grown into a trusted exterior cleaning service for residential and commercial customers across the local area.
Today, the service is led by JEM through GEMS REACH AND WASH CLEANING LIMITED — a company registered in England and Wales (Company No. 17135499) — continuing the local reputation built over the years while bringing professional structure, full public liability insurance and a commitment to high standards of service.
We use modern reach & wash water-fed pole systems, allowing us to clean windows, gutters, fascias and other exterior surfaces safely from the ground — with no ladders, reduced risk to your property and a clean, streak-free finish.
