DNA Cleaning Solutions provides commercial window cleaning in London for offices, shops, medical centres, schools, warehouses and business premises. Our trained team cleans glass, frames and sills inside and out on a schedule that suits your business.
Clean windows make your premises look cared for and let in more natural light for the people working inside. Dirty, streaky glass is one of the first things customers and visitors notice.
Every contract starts with a site visit. We look at the number and type of windows, how they are reached and when the work can be done safely, then agree a cleaning plan and schedule with you.
Commercial window cleaning London from DNA Cleaning Solutions keeps the glass on offices, shops, medical centres, schools and warehouses clean inside and out. We clean windows, frames, sills, partitions and shopfronts on a schedule agreed after a free site visit, as a standalone service or alongside your regular cleaning.
Glass on a busy road collects traffic film far faster than glass facing a quiet courtyard, so one building can need two frequencies. At the site visit we split the windows into groups and set a schedule for each:

The Workplace (Health, Safety and Welfare) Regulations 1992 include a regulation on windows being cleaned safely, and we plan access with that in mind. Need paving or walls cleaned as well? See our external cleaning service, or request a free quote.

Regular commercial window cleaning keeps your building looking professional and protects your glass and frames.
London’s traffic, rain and pollution leave a film on glass that builds up quickly, especially on busy roads and around Heathrow. Our commercial window cleaning service keeps offices, shops and business premises across London looking their best.
Shopfronts and entrances usually need cleaning weekly or fortnightly. Office windows are typically cleaned monthly or quarterly, depending on the location and how quickly they get dirty. We recommend a frequency at the site visit and can adjust it at any time.
We plan access for every building before work starts and agree times that avoid disruption to your staff and customers. For glass at height, see our high-level cleaning service.
Window cleaning can be added to your regular office cleaning or commercial cleaning contract, or combined with our other external cleaning services such as pressure washing.
