The range
If it holds glass, we make it.
Forty years of it, here in Brighton.
Everything below is our own work, fitted in Brighton, Hove and across Sussex. Filter to what you are after.
uPVC casement windows
The workhorse. A rated as standard, dozens of finishes.
Sliding sash windows
Period looks, modern performance. Ideal for Brighton terraces.
Bow and bay windows
We survey the structure properly so the bay is carried, not bodged.
Tilt and turn windows
Tilt for a safe trickle of air, turn right in to clean it from inside.
Aluminium windows
Strongest frame, thinnest sightline, the most glass you can get.
French casement windows
Opens wide with no centre bar, so the view stays whole.
Composite front doors
Secured by Design spec. The first thing anyone sees, so it should look it.
uPVC doors
Sensible money, multi point locked, made to measure.
French doors
Both leaves open. Simple, classic, and it never dates.
Sliding patio doors
Big panes, small footprint. Nothing swings into the room.
Stable doors
Top open, bottom shut. Handy with dogs, children and a hot kitchen.
Roof lanterns
The cheapest way to make a flat roofed extension feel twice the size.
Conservatories and orangeries
Built to be used in February, not just July. Insulated roofs, proper heating allowance.
Coloured glass splashbacks
Toughened, matched to any colour, cut to your sockets.
Shower screens
Frameless where the wall allows. Easy clean coating included.
Glass balustrades
Keep the view. Structural glass, engineered to the drop.
Mirrors and mirrored glass
Cut, polished and drilled here. Any shape you can draw.
Glass worktops
Heat proof, seamless, and it wipes clean in one pass.
Frameless glass doors
Commercial and domestic. Light through the whole plan.
Sandblasting
Privacy without losing light. House numbers, logos, patterns.
Glass repairs
Broken pane at nine.
Fitted by lunch.
You do not need a whole new window because one unit has misted up or a pane has gone through. We hold glass at the workshop on Roedean Road and cut to size ourselves, which is why we can often turn a repair round the same day.
- Misted or blown unitsThe seal has failed. We swap the glass, keep the frame.
- Smashed panesBoarded up today, glazed as soon as the unit is cut.
- Handles, hinges and locksWill not shut, will not lock, dropped on its hinges.
- Toughened and safety glassDoors, low level glazing, anything that has to be right.
Single misted units typically £95 to £220 fitted, depending on size and glass type.
Absolutely brilliant. Called them at 9am with a broken window pane, they had come by, measured, quoted and then came back and completed the job by lunch time. Thank you so much!
How it works
Four steps, and you know where you stand at every one.
-
01
Your instant price
Sixty seconds on this page and you have a realistic range. If it is nowhere near your budget, you have lost a minute, not an evening.
-
02
A free survey, on your terms
Someone who actually measures for a living comes out, checks the openings, the lintels and the access, and answers your questions. Then they leave.
-
03
A fixed price in writing
One number, itemised, valid for thirty days. No discount that expires at midnight, because we never inflated it in the first place.
-
04
Made, fitted and signed off
Built in Britain, fitted by our own teams, old frames taken away, and your FENSA certificate through the door afterwards.
Why us
You already know how the big
double glazing firms sell.
We have spent forty years being the alternative to it.
 |
A typical national double glazing firm |
|
|---|---|---|
| Getting a price | On this page, in a minute. Then fixed in writing after a survey. | Book an appointment and wait for a visit. |
| The appointment | A surveyor measures and goes. Usually under an hour. | A commission paid salesperson, two to three hours at your table. |
| The price you are shown | One price, no theatre. It does not move if you sleep on it. | A high list price, then a discount that expires tonight. |
| Who fits it | Our own fitters, the same faces year after year. | Whichever subcontract team is in the area that week. |
| Where it is made | Made in Britain by Sternfenster and Smart Systems. | Often badged, frequently imported. |
| Small jobs | One misted pane is a real job to us, often done same day. | Minimum order values. Small work is not worth their overhead. |
| If something goes wrong | Roedean Road, Brighton. Ten minutes away, forty years at it. | A national call centre and a ticket number. |
| Guarantee | 10 year warranty, FENSA registered, CERTASS assessed. | Only as good as the company still trading. |
Comparison describes common practice in the national double glazing market. We are happy to be judged against any of them on price, spec and finish.
Reviews
Forty years of word of mouth in one city.
★★★★★
We are extremely happy with our new bifold doors installed by A1 Glass. They were very professional and left no mess. The new doors finish transform the extension. We are very happy to recommend anyone thinking of using them.
★★★★★
Got recommended A1 by a trade person, spoke to Pat on the phone, guys came out and measured next morning and had replaced the glass by the end of the week, even cut down the glass on site as the frame was not true. Top service all round, cannot recommend enough.

Trade recommends us, and so do neighbours. Have a look for yourself.
