Mitford cleans windows by hand — squeegee, chamois, and specialist frame polish on every visit. No water-fed poles. No shortcuts. Serving homes and businesses across Mayfair, Greenwich, and Blackheath.
Mitford is a London window cleaning company built on a single belief: that cleaning a window properly — by hand, with the right tools and the right attention — produces a result that no telescopic pole can replicate.
We are four people. Arthur Mitford founded the company and covers Mayfair personally. James and Steven work across our Greenwich and Blackheath territory. Edward manages scheduling and client relations across both areas. Every client knows who is coming, every team member is DBS checked, and every visit is preceded by a text the evening before.
We are not the cheapest option in London. We are the right option for clients who notice the difference between a window that has been washed and one that has been properly finished — and who would prefer the same trusted person at their door each time.
Reach-and-wash systems produce acceptable results on modern aluminium windows. But they leave frames untreated, miss putty lines and glazing bars, and cannot replicate the clarity of a hand-finished pane on a period property. We clean by hand, treat every frame and sill with specialist polish, and finish with a chamois. It takes longer. The result is visibly different.
One thing, attended to properly. We clean windows — residential and commercial — by hand, every time, without exception.
Homes of every kind — terrace, townhouse, period flat, or mansion block. Glass, frames, sills, and ironmongery attended to on every visit. Regular rounds or one-off cleans.
Shopfronts, offices, restaurants, galleries, and boutiques. Attended before trading hours, or at a time to suit the business. Scheduled programmes across all our territories.
Glass roofs, ridge bars, and the intricate framework of conservatories cleaned entirely by hand — including sections that water-fed systems consistently leave marked or untreated.
Georgian and Victorian sash windows require specific knowledge — glazing bars, putty lines, rope channels, and original glass. We clean them correctly, without risk to historic fabric.
Specialist polish applied to every timber, metal, and uPVC frame and sill on every single visit — not an optional extra. It conditions the material, repels future soiling, and extends the result considerably.
Both sides cleaned as standard where access allows. Many clients book exterior-only for routine visits and interior twice yearly. We will advise what makes sense for your particular property.
1
Tell us your address and property type. We respond the same day with a clear, honest price — no call-out fee, no obligation, no small print.
2
You receive a text message the evening before every visit. You know who is coming and roughly when. No strangers at the door unannounced.
3
Squeegee, chamois, specialist frame polish. Every pane finished by hand. Frames and sills treated on every single visit without exception.
4
We work on scheduled rounds — monthly, six-weekly, or eight-weekly depending on your property. The same person each time. You don't need to be home.
Every member of the Mitford team is DBS checked, personally known to Arthur, and held to precisely the same standard on every property they attend.
Arthur founded Mitford in 2024 after twenty years working across London's property and estates world. He had spent long enough watching windows cleaned badly — frames untreated, putty lines ignored, streaks left on cold glass — to decide there was a better way to do it, and that he would do it himself.
"I clean every Mayfair client personally. That isn't changing. The standard on a property is only as reliable as the person attending it, and I'm not prepared to delegate that until I'm certain someone else meets it exactly."
James works across both Mitford territories and has been with the company since its first week. He came from a background in decorating and building maintenance, which means he reads a window's condition — frame, putty, ironmongery — before he lifts a squeegee. Clients who have moved between postcodes have asked for James specifically.
"A clean window and a properly finished window are two different things. Most people clean the glass and leave. We don't leave until the frame is treated and the sill is dry."
Steven is Mitford's Greenwich and Blackheath specialist, covering the period terraces, Victorian semis, and independent shopfronts of SE3 and SE10. He has particular experience with sash windows — the ropes, runners, and original glass that make up the finest houses around Greenwich Park — and approaches each one as the individual thing it is.
"Greenwich has some of the best domestic architecture in London. The windows in these houses deserve to be looked after properly. Most of them haven't been, for years."
Edward manages scheduling, client communication, and accounts across both Mitford territories. He is the person who sends your text the evening before, responds to your quote within the hour, and ensures that a change of visit, a new property, or a specific instruction reaches the right person before they arrive at your door.
"Most of the friction in a service relationship is administrative — the wrong person shows up, the invoice is wrong, nobody tells you there's a delay. Eliminating that is most of my job."
Arthur and James cover Mayfair and surrounding streets. Private houses, mansion flats, and commercial premises — from shopfronts on Mount Street to residential properties off Grosvenor Square. Quotes given within the hour. First visits usually available within the week.

Steven covers Greenwich and Blackheath — period terraces, Victorian semis, Blackheath Village shopfronts, and the Georgian streets around Greenwich Park. Fine architecture that deserves windows treated with the same care as the buildings that hold them.

Most window cleaners in London now use water-fed extension poles — efficient, safe, and adequate on modern aluminium windows. For older or finer properties, adequate is not a standard we find acceptable.
Traditional tools in trained hands produce a clarity that pure water cannot match on period glass. No residue, no tide marks, no water pooling in frame joints. A properly finished window is visibly different — and stays cleaner for longer.
We treat timber, metal, and uPVC frames and sills with specialist polish every single time — standard practice, not an optional extra. It conditions the material, repels dirt, and makes the result last significantly longer than glass-only cleaning.
Glazing bars, putty lines, deep sill edges, ironmongery, inside sash runners. These tell you whether a window has been cleaned or merely washed. We attend to all of them, because they are visible to anyone who looks.
Victorian and Georgian glass is thinner and more vulnerable than modern glazing. Pressure-brushing from a pole system causes micro-abrasion over time. Hand cleaning is the only appropriate method for original glass, and the only method we use.
Arthur has been attending to our shopfront on Mount Street for three months. He arrives before we open, finishes before a customer has noticed him, and the glass looks exactly as it should. We have not had to think about it once since he started.

Steven has been cleaning the windows of our Georgian terrace since we moved in. He is the same person every time, always texts the day before, and actually treats the frames — which our previous cleaner never did. The difference to the paintwork over winter was noticeable.

I have original Victorian sash windows throughout the house. Several window cleaners over the years have either scratched the glass or left the runners wet. Mitford is the first company that has understood what the windows actually are, and treated them accordingly.

We respond to every enquiry the same day, usually within the hour. Tell us your address, property type, and roughly what you are looking for — we will come back with a clear price and an honest assessment of what we can do for your property.
We are a small team and we keep it that way deliberately. Every Mitford client knows who is coming to their property. We do not send whoever is available. We send the right person.
