Black edges, often called edge creep, are corrosion of the silver layer, usually started by moisture or cleaning fluid getting into the edges, or by an unsuitable adhesive. Once the silver has corroded it cannot be restored, so the mirror has to be replaced.
Templating lets a mirror follow sloping ceilings, curved alcoves, skirting lines and fitted furniture. Cut-outs for sockets and switches are marked on the template, and the faceplates are removed and refitted so the mirror sits neatly behind them.
Large mirrors are usually fixed with mirror adhesive and supported at the base by a slim channel or clips while the adhesive cures and afterwards. Smaller mirrors can be screw-fixed through drilled holes with decorative caps, which also lets them be removed later.
A safety-backed mirror has a film bonded across its back that holds the pieces together if the glass breaks, so fragments stay on the backing instead of falling or scattering. Some backing films are classified for impact under BS EN 12600, and the film is applied before fitting.

Windsor at a glance
- Postcodes covered
- SL4 and the surrounding area, including Slough, Egham and Staines
- Coast
- Windsor is well inland, around 67 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Windsor the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. A mirror opposite or beside a window reflects daylight deeper into a room, which helps dark north-facing spaces through winter. Low direct sun on a large mirror can cause glare, so its position and any tint are worth considering.
- Access and setting
- Older rural homes often have uneven walls of stone or lime plaster, which can distort a bonded mirror unless the wall is levelled or a backing board is used. Damp solid walls also need checking before a mirror is fixed to them.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Bespoke Mirrors in Windsor: questions
How should I clean a mirror without damaging it?
Spray glass cleaner onto a soft, lint-free cloth rather than directly onto the mirror, then wipe and buff dry. That stops liquid running down and soaking into the bottom edge, which is where black edges usually start. Avoid abrasive pads and harsh chemical cleaners, and dry the edges after cleaning in bathrooms.
Why do mirrors go black around the edges?
Black edges are corrosion of the silver layer behind the glass, usually caused by moisture or cleaning fluid getting into the edges, or by an adhesive that reacts with the backing. Bathrooms are especially at risk because of steam. The damage cannot be reversed, so the mirror needs replacing, ideally with better edge protection and a compatible adhesive.
How long does a bespoke mirror take?
Plain mirrors cut to size are often ready soon after measuring, while bevelled, tinted, safety-backed or shaped mirrors take longer to process. Fitting is usually completed in a single visit, though full gym or studio walls can take longer. Your written quote sets out the expected timescale, and we confirm the date when the mirror is ready.
How is a large mirror fixed to the wall?
Large mirrors are usually bonded with an adhesive made for mirror backing and supported along the bottom edge by a slim channel or clips. The support carries the weight while the adhesive cures and adds security afterwards. Smaller mirrors can be screw-fixed through drilled holes with decorative caps, which makes them easier to remove later.
