End of Tenancy Cleaning in Knightsbridge

Second floor, portered building, garden square near Cadogan Square. Two bedrooms, two bathrooms, big reception with dining area, kitchen, and small terrace that looks onto the square garden. Diplomatic tenant — Middle Eastern embassy — 18 months at £5,200/month. Knight Frank managing. Embassy coordinator arranged the checkout for next morning.

Porter parking underground — we book day before. Goods lift to second floor. We show insurance documents at desk. Porter gives us time: 09:00 to 15:00.

Reception room first. This is big room — maybe 30ft long. Hardwood parquet floor, herringbone pattern. We use specialist product, work with the grain, barely damp. Two tall windows with shutters — shutters wiped each slat, windows cleaned, tracks vacuumed. A marble fireplace — white, maybe Carrara, with grey lines. pH-neutral cleaner, soft cloth, each part wiped one by one. Mantel, sides, inside, hearth. There is small mark on hearth — looks like coffee. pH-neutral removes most but small shadow stays in the stone. We photograph. Marble is porous. This is material, not dirt.

The ceiling is high — maybe 3 metres. Cornicing is very detailed, lots of small shapes. Extension brush, slow, careful. Takes maybe 15 minutes just for this room cornicing. Two radiators — behind each one we clean with long brush.

Kitchen. Separate room, good size. Miele integrated oven, induction hob in marble island. We are very careful here — marble island means no acid anywhere near it. Oven door off, glass out, spray, 20 minutes. One pass enough. Hob wiped with glass product. Extractor — big, ceiling-mounted — filter out and soaked. Fridge-freezer cleaned. Air conditioning grille above the door — vacuumed and wiped. Floor is stone tile, pH-neutral mop.

Two bathrooms. The en-suite has marble walls and floor — everything is marble. Walk-in shower, glass panel, rainfall head. We descale the chrome and glass only. Marble walls — pH-neutral wipe only. If descaler touches marble, it etches. We are very careful, we use cloth to protect marble edge when we descale the glass next to it. Screen at ~260 ppm, one pass. Taps done — these are brass, so we use brass product, not chrome product. Different. Toilet done. Floor mopped with marble-safe product.

Main bathroom similar but with bath — freestanding, on marble floor. Waterline light, 18 months diplomatic tenant, not heavy use. One pass. Behind bath cleaned.

Two bedrooms. Both have parquet floors (same product), built-in wardrobes (wiped inside), and tall windows with shutters (slats wiped, glass cleaned). Master has dressing room — every shelf, every rail wiped.

Small terrace — swept, glass balustrade wiped, threshold track cleaned.

Knight Frank come next morning with embassy coordinator. This is formal checkout — clipboard, every room, every surface. Marble fireplace: checked, coffee shadow noted and accepted. Cornicing: looked at from two angles. Parquet: walked in socks. Shutters: finger-tested. Kitchen: oven opened, marble island inspected carefully. En-suite: marble walls checked (no etch marks — good, we were careful). Brass taps: polished. Terrace: clean. Maybe 20 minutes for whole flat. Passed.

Deposit processed through embassy. 6 working days. Full return.

This is most expensive area we work. The flat is beautiful but also the flat is where one mistake costs a lot. Wrong product on marble — you etch it. Wrong product on brass — you scratch it. Acid splash on parquet — you mark it. We carry right product for every surface because in Knightsbridge there is no room for getting it wrong. If the coffee mark or the marble shadow had been disputed, our photographs show it is the material. Our guide on deposit dispute evidence explains how this works for premium properties.
