Why MMAK
Your advantages with MMAK
Fixed-price guarantee
You receive a binding per-square-metre price after an inspection — with no hidden surcharges. What is agreed applies; even with recurring visits, the price stays predictable.
Inside, outside and frames
We clean glass surfaces on both sides, plus frames, rebates and windowsills. So the entire window area is clean — not just the pane you notice at first glance.
One dedicated contact
You have a named contact who knows your properties and is reachable. No rotating hotlines, no explaining from scratch at every visit.
Cover guarantee when staff are out
If someone is unavailable, we organise a replacement — your agreed cleaning cycle continues. With recurring window cleaning in particular, this reliability counts.
Public liability insured
Our work is covered by public liability insurance. Should anything be damaged during the job, you are not left out in the rain.
