Rear extensions changed the Tooting terrace more than any other alteration of the last twenty years, and they changed the cleaning with it. Knocking through to a wide glazed back wall with rooflights overhead turns a dark galley into the main room of the house, and it introduces a large area of glass at heights nobody can comfortably reach, with running gear at floor level that collects everything the garden produces. The glass is what people notice; the tracks and seals are what actually fail.
Rooflights, and their two very different sides
A flat glazed rooflight has an interior face that films over with cooking aerosol and a exterior face that collects atmospheric grime, pollen and bird debris. They need opposite treatments. Inside, a degreasing solution on a cloth wrapped pole, worked in overlapping strokes and dried before it dries itself, since anything left to evaporate on overhead glass streaks straight away. Outside, plenty of water and a soft brush, with the surrounding upstand and flashing cleared at the same time so debris does not wash back down.
Bifold tracks, rollers and grit
Folding doors carry their weight on small wheels running in a shallow bottom track, and that track sits at the exact level where garden soil, seed and leaf fragments collect. Grit in the channel wears flats on the rollers, and once a leaf is dragging the doors stop closing square. Vacuuming the full length with a crevice tool comes first, then a brush along the channel, then a barely damp cloth. Lubricant is applied afterwards or not at all, since oil on grit makes a grinding paste.
Thresholds and drainage channels
Level threshold details rely on a drainage channel immediately outside, usually covered by a slotted grating. It silts up quietly. Once it does, rainwater ponds against the door and eventually finds its way past the seal, and the first sign indoors is a dark line along the edge of the floor covering. The grating lifts out, the channel is cleared to the outlet and flushed, and this needs doing at least twice a year in a garden with trees.
Frames, gaskets and the black marks in the corners
Aluminium frames are powder coated, and abrasive pads take the coating off in a haze that cannot be restored. They are washed with a neutral solution and dried. The rubber gaskets around each pane hold a black line of mould in the bottom corners where condensation runs down and sits, and that comes out with a soft brush and a fungicidal solution rather than by picking at it, which tears the seal.
What all that light reveals
Bright side-on daylight is unforgiving, and the first thing it exposes is the state of everything soft. Sofa arms and seat cushions in a room like this show every mark, and sofa cleaning in Tooting restores fabric that looks permanently grubby rather than genuinely worn. Floor coverings under a glazed roof fade unevenly and hold dust in a way that dark rooms conceal, which is where carpet cleaning cover across Tooting earns its place.
Open plan, and where the cooking ends up
Knocking a kitchen into a living space means everything produced at the hob now lands on the sofa, the shelves and the underside of the rooflight instead of staying in a closed room. Extraction that suited a galley is undersized for the volume, and a recirculating hood with a spent carbon filter relocates the problem rather than solving it. The cleaning follows the airflow: the wall above the hob, then the ceiling line, then everything downwind, which in a long extension means the far end of the room.
Reach, safety and what falls outside a visit
Everything described here is done from floor level with poles or from a low step. Anything requiring a ladder against a rear elevation, roof access or work above a lightwell is a different trade with different equipment, and it is better identified at the point of scoping than improvised on the day. Charges follow visit length and team size, with glazed area the main variable. Comparable work nearby runs through cleaning services across Wandsworth and professional domestic cleaning services in Earlsfield, and the full list appears on house cleaning.
