Made to measure mirrors in Gainsborough
Mirrors must be bonded with an adhesive made to be compatible with mirror backing. Some general-purpose adhesives and acidic sealants can attack the protective coatings and the silver, causing dark patches that spread from behind. We only use mirror-compatible products.
To protect the edges, spray glass cleaner onto a soft cloth rather than directly onto the mirror, so liquid does not run down and soak into the bottom edge. Avoid harsh or abrasive cleaners, and dry the edges after cleaning in bathrooms.
A bonded mirror follows the surface behind it, so an uneven wall can bend the reflection. We check flatness at survey, and on uneven plaster or stone walls the mirror may need a flat backing board or the wall levelling first to avoid a wavy, distorted image.
The price depends on mirror size and thickness, the number of panels, the edge finish, tint or low-iron glass, safety backing, cut-outs and the fixing method. Gym walls, very large single sheets and difficult access also affect cost. See the guide prices for typical ranges.
Included as standard

Gainsborough at a glance
- Postcodes covered
- DN21 and the surrounding area, including Retford, Scunthorpe and Lincoln
- Coast
- Gainsborough is well inland, around 36 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Gainsborough the midwinter sun reaches about 13° above the horizon at noon, with roughly 7.2 hours of daylight, rising to about 60° and 16.8 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.

Choosing your bespoke mirrors
Low-iron mirror
Mirror made on low-iron glass, which reduces the slight green cast of standard glass for a brighter, more colour-accurate reflection.
Safety-backed mirror
Mirror with a bonded backing film that holds fragments together if it breaks, recommended for doors, full-height mirrors, gyms and children's rooms.
Clear silver mirror
Standard silver-coated float glass mirror, cut to size, suited to most rooms, wardrobes and wall mirrors where a true, neutral reflection is wanted.
Bespoke Mirrors in Gainsborough: 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.
What affects the cost of a bespoke mirror?
The main cost drivers are the size and thickness of the mirror, the number of panels, the edge finish, any tint or low-iron glass, safety backing, cut-outs and the fixing method. Very large single sheets, access through narrow stairs and full mirror walls also affect the price. See the guide prices for typical ranges.
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.
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.
