Four quick questions. Most quotes come back the same day.
Two things separate a mirror that lasts from one that does not. The backing, because in a bathroom or a gym you want safety backed mirror that holds together if it breaks. And the fixing, because a heavy mirror held on with foam tape eventually comes off a wall, and in a damp Dunedin bathroom it comes off sooner.
Why old mirrors go black at the edges
That is the silvering breaking down where moisture has got behind the backing, and it starts at the exposed edge. It is not cleanable and it does not stop. Once it has started, the mirror is on its way out.
Sealing the edge and keeping the back ventilated slows it. In a bathroom the real fix is a mirror made for the job with a moisture resistant backing.
Edges and fixings
A cut mirror has a raw edge that will cut you and chip easily. We polish or bevel it. A bevel gives a wider decorative edge and suits a plain wall mirror, a flat polish is neater under a frame or in a recess.
Fixing depends on weight and substrate. Small mirrors take mirror adhesive suited to the backing. Larger ones get mechanical fixings, either clips or through fixings into solid backing, because adhesive alone on a plasterboard wall is not enough.
Wardrobe and gym mirrors
Sliding wardrobe doors take mirror in an aluminium frame, and replacement panels can go into the existing door frame in most cases. Gym mirrors are large and get walked into, so they are always safety backed and mechanically fixed.
Fixing a mirror so it stays up
Adhesive, clips or through fixings
Small mirrors take a mirror safe adhesive, which matters because ordinary construction adhesive attacks the silvering from behind and shows as black blotches within a year.
Anything large or heavy gets mechanical support as well: clips at the bottom edge or through fixings into solid backing. Adhesive alone on plasterboard is how mirrors end up on bathroom floors.
Why bathroom mirrors go black
Moisture gets behind the backing at the exposed edge and breaks down the silvering. It starts as a dark line and spreads inward, and it cannot be cleaned or stopped once it has begun.
A mirror made for wet areas has a moisture resistant backing and sealed edges, and it lasts several times longer in the same room.
The mirror supply and installation process at Window and Glass Repair Dunedin in Dunedin
Supply and fit work is simple to describe and easy to get wrong at the measure, because nothing can be adjusted once the product is made.
Template at the measure
The opening is measured and anything that is not a plain rectangle is templated. Cut outs, apertures and irregular shapes are recorded then, because they cannot be added afterwards. In older Dunedin housing very little is truly square.
Agree the specification in writing
Product type, thickness, backing or mesh, edge finish and fixing method, all confirmed before anything is ordered so what arrives is what you expected.
Talk through the position
Where the product goes affects both cost and performance. Putting a pet door into a smaller fixed pane rather than a large slider panel means a smaller replacement pane and a lower price, and it is worth looking at every option in the room.
Specify for humidity where it applies
A mirror in a Dunedin bathroom needs a backing rated for moisture. Standard backing in a wet area with limited ventilation is the single most common reason we return to replace one within a few years.
Manufacture to order
Almost everything in this category is made to your measurements, so there is a real lead time. Window and Glass Repair Dunedin confirms the date rather than estimating it.
Fit, fix and adjust
Fitted square, fixed properly and adjusted so everything operates as it should. Window and Glass Repair Dunedin does not leave a product that functions but sits crooked.
Clean down and explain the care
Site cleared, product cleaned, and you get told how to look after it. Most of what shortens the life of these products is being cleaned with the wrong thing.
Getting the details right in Dunedin
Small jobs are where corners get cut, because nobody inspects them and the consequences take years to appear.
Humidity is the enemy of most of these products
Cold rooms, limited ventilation and long winters mean bathrooms and laundries here stay damp far longer than they would further north. Specification has to reflect that rather than defaulting to the cheapest option.
Old openings are rarely square
In Victorian and Edwardian housing the opening has moved with the building. Templating rather than measuring two dimensions is the difference between a clean fit and a visible gap down one side.
Screens make windows get opened
Where insects or a cat are the reason a window stays shut, a screen is the cheapest ventilation improvement available. In a damp house that matters more than it sounds.
Safety glazing still applies
A shower screen, a splashback beside a hob and a pet door in a slider panel are all positions with requirements. Window and Glass Repair Dunedin specifies to the standard rather than to what is quickest.
What mirror supply and installation costs in Dunedin
Small supply and fit jobs are priced by the product and the measure, and the measure is where the cost is decided.
Made to order, always
Almost everything in this category is manufactured to your measurements, so the price follows the size and the specification rather than a catalogue. There is a real lead time and Window and Glass Repair Dunedin confirms the date rather than estimating it.
Where the position changes the price
Putting a pet door into a smaller fixed pane rather than a large slider panel means a much smaller replacement pane. Looking at every option in the room before choosing is often worth several hundred dollars.
Specification for wet areas
A mirror in a Dunedin bathroom needs a moisture rated backing, and a splashback beside a hob needs toughened glass. Standard product in a wet or hot position is the single most common reason we return within a few years.
Repair before replacement
A torn flyscreen in a sound frame is remeshed for a fraction of a new unit. The frame is the expensive part and it usually outlives several meshes, so Window and Glass Repair Dunedin quotes the remesh first.
Getting the specification right in Dunedin
Three decisions that are permanent once the product is made.
Edge finish and fixing method
A polished edge is clean and modern, a bevel reads traditional, and both are done at manufacture. Mechanical clips allow a mirror to be removed later, adhesive gives a cleaner look and is effectively permanent.
Mesh type on screens
Standard fibreglass for insects, heavier pet resistant mesh where a cat or dog pushes at it, and fine mesh where sandflies are a problem. Fine mesh lets less air through, which matters in a house you are ventilating to manage damp.
Safety glazing still applies
A shower screen, a splashback and a pet door cut into a slider panel are all positions with requirements under the standard. Window and Glass Repair Dunedin specifies to it rather than to whatever is quickest to source.
Specifying a mirror for a Dunedin room
Mirror is glass with a coating on the back and the coating is what fails, so the specification decides its life.
Silvered backing and edge sealing
Moisture reaching the backing causes the black edge spotting people recognise from old bathroom mirrors. Properly sealed edges and a quality backing are what prevent it.
Bathroom grade in wet areas
A mirror in a bathroom needs a backing rated for humidity. Fitting a standard mirror in an ensuite is the single most common reason we are back replacing one within a few years.
Thickness and size
Larger mirrors need more thickness to stay flat. A thin large mirror distorts the reflection visibly, which is the giveaway on a cheap installation.
Fitting and edge finishes in Dunedin
How a mirror is fixed decides whether it stays flat and whether it can ever be removed.
Mechanical fixing or adhesive
Clips and channels hold the mirror mechanically and allow it to be removed later. Adhesive gives a cleaner look and is effectively permanent, and it needs the right product because the wrong adhesive attacks the backing.
Polished, bevelled or framed edges
A polished edge is clean and modern. A bevel catches light and reads more traditional. Both are done at manufacture and cannot be added afterwards.
Cut to size and cut outs
Mirrors are cut to the opening and can take cut outs for a shaver socket, a light or a fitting. Those are templated at measure, because a cut out cannot be added once the mirror is silvered.

Mirror Supply and Installation in Dunedin: common questions
Why has my bathroom mirror gone black around the edge?
Moisture has got behind the silvering at the exposed edge. It cannot be cleaned off and it will keep spreading.
Can you cut a mirror to fit an odd space?
Yes, including cut outs for lights, shaver points and shelves.
Can you replace the mirror in my wardrobe door?
Usually. The panel comes out of the existing aluminium frame and a new one goes in.

Got three quotes for retrofitting the front of the house. Only ones who measured every opening and explained why the south facing rooms needed different glass. Fourteen windows over three days and the difference in the mornings is obvious.
Landlord here. Had four flats assessed before the inspections. Two just needed sashes freed up and stays replaced rather than new joinery, which saved me a fortune. Straight answers and a written report I could hand over.
Slider had been jamming for years and we assumed it needed replacing. Turned out to be rollers and a bent track. Two hours, a fraction of the price we were braced for.
Fogged unit in the lounge, measured on the Tuesday and in by the following Monday. Fair price and they cleaned up after themselves.
