Green-framed glass doors along a brick home, opening onto a timber deck and garden — Glass doors along the deck, clear on both sides

Glass doors, sliders and window tracks, cleaned

The doors onto the deck get more hands, paws and salt than any glass in the house. We wash glass doors and sliders with soapy water, squeegee them clear on both sides, and clean out the tracks as an extra on the same visit.

Sliders and glass doors

Glass doors pick up handprints on the inside and salt and dust on the outside, and a big slider shows every streak when the sun drops low. Each door gets soapy water first, then the squeegee, then soft cloths round the edges, on both sides.

The clip shows one of Kosta’s own jobs: a white-framed door from soap to clear. Press play to watch it. Kosta does the cleaning himself, with the team alongside on the bigger houses.

We had both inside and outside windows done and after the recent weather, they had gotten pretty grubby, especially our larger lounge sliding doors.
Our windows are sparkling again - Kosta did a fantastic job and takes great pride in doing his work well. He was respectful, professional and warm. …

A white-framed glass door: soap on, then the squeegee

Window and slider tracks

Tracks collect dust, dead bugs, leaves and grit, and a dirty track makes a slider drag every time it opens. Track cleaning is an extra you add to a window clean: tick Tracks too on the form and Kosta includes it in the quote.

Done on the same visit as the glass, so the doors look right and run right.

By the sea, salt finds its way into the tracks and onto the joinery as well as the glass, and window makers suggest a wash about every three months there, more often right on the water.

Lounge sliders, kitchen doors and bedroom glass

Inside, the doors take the knocks: kids’ hands at kitchen height, dog noses at the bottom, steam from cooking. We clean the inside face with the same care as the outside, working round the furniture and the pot plants, so the room looks straight through to the deck.

Glass doors on the bedrooms, a slider off the kitchen, French doors to the garden: tell us how many on the form, and a photo of the biggest one helps Kosta quote.

How each door is done

Soapy water
Washed over the whole pane, inside and out, to lift handprints, salt and dust.
The squeegee
Drawn across in clean strokes, so the water comes off in one go.
The edges
Soft cloths and detail towels round the frame line, where streaks like to hide.
The tracks, if added
Cleaned out on the same visit, so the slider runs as well as it looks.

Walls of glass and long runs of sliders

Floor-to-ceiling glass onto the water and runs of sliders along a deck are some of the best-looking glass in the Bay, and the bigger the pane, the more the finish matters. Kosta works each one by hand to the edges, so from inside you look at the view, not the glass.
