Deep clean for tired windows

Neglected glass

Some windows need reviving, not just wiping

A standard clean keeps good glass good. But glass that has been left for seasons — or years — builds up layers a quick wipe will not shift: baked-on pollen, traffic film, paint flecks from the last renovation, hard-water spotting under a leaking spout, and the grey haze that settles into frames and tracks. The deep clean is the reset button — a slower, more thorough pass that brings tired windows back to a state a regular clean can maintain.

Christchurch is particularly good at ageing glass. The dry, dusty nor'westers of summer, the salt air that drifts further inland than people expect, steady winter condensation feeding mould in aluminium tracks, and construction dust from a city still renewing itself — each leaves its own signature on the pane. The deep clean reads those layers and works through them in order, gentlest effective method first.

What a deep clean covers

Tracks and reveals are vacuumed and scrubbed out, because neglected sills hold grit that scratches glass if it is dragged across. Frames get a full wash rather than a wipe — oxidation, cobwebs and insect debris included. The glass itself is scrubbed thoroughly, with careful attention to bonded contaminants like paint spots and sticker residue, then squeegeed and detailed at every edge. Screens, where fitted, are brushed and washed so they stop dulling the glass behind them.

Delicate surfaces set the pace: coated, tinted and leadlight glass is treated with methods suited to it, and any pane whose coating or seal has genuinely failed is pointed out honestly rather than polished in vain — some things need a glazier, not a squeegee.

After the revival

Once glass is back to baseline, keeping it there takes far less effort — which is where the regular routines come in. Homes move onto home window cleaning, and workplaces onto business and office cleaning. As a rough guide, a twice-yearly rhythm in spring and autumn holds the line for most Christchurch properties.

Who it suits

New homeowners facing the previous owner's decade of neglect, landlords resetting a rental between tenancies, buyers and sellers sprucing up for photos and open homes, and workplaces whose frontage has quietly gone grey. If you cannot remember the last clean, this is the one to start with.
