Glaziers
Measure, cut, finish, fit and install flat glass and mirrors.
Glass after a break-in
You are a glazier on the emergency call list for a glass company, and your phone rings at 5:40 on a cold morning. A jewellery shop owner says her front window was smashed overnight. She is standing in the street with the police and shop staff and needs the shop secure before the street fills up with commuters.
Choose what you would do. Then see what happens. There are often good reasons for each choice.
Thank goodness you are here. The police have finished and I need the window back in as soon as possible. Can you put in a new pane this morning, the same as before? I cannot leave the shop open like this.
Measure the opening and agree a secure temporary cover now, then order the right glass
The shop is secured within an hour with a cover that keeps the weather and the street out. Hui Min can open the back office and breathe. The proper glass arrives later in the week.
Promise her a new pane by lunchtime, even though you have not checked what type of glass was there
You ring around, and the right type is not in stock until Thursday. Hui Min has been waiting all morning for a promise you could not keep, and she says so loudly.
Tell her the glass is up to her insurer and leave until they have approved the work
You avoid the risk of doing unapproved work, but the shop is left open for hours. Hui Min needed a safe temporary fix first, and you were the only person who could give her one.
Can you give me a cheaper pane than the original one? The insurance will not cover all of it, and the old glass was thick and expensive. Surely a standard thin pane does the same job.
Use the thinner one, since it is her shop and her money
Hui Min saves money, but a thinner pane does not resist impact as well as the original, which is the whole reason for a shop window. She chose it, but nobody explained what she was giving up.
Agree and keep it quiet, to avoid a lengthy conversation
The thin pane goes in and nobody asks. A few weeks later it cracks from a small knock, and Hui Min wants to know why a professional put in glass that was not right for the job.
Explain what the original glass was for, and show her the options and the difference
Hui Min picks a middle option that meets the requirements for a shopfront and fits her budget. She appreciates being shown the choice and not simply being told no.
The new pane is on the trolley and the street is busy now. I think we can lift it by ourselves if we go slowly. The suction cups are in the van but they are in a different box. Can we just carry it?
Lift it by hand, since you are both strong enough and the street is getting busier
A gust catches the pane and you both stumble. Nobody is hurt, but the glass chips on the kerb, and you have just lost a morning and a piece worth far more than the minute you saved.
Fetch the cups, but leave the footpath open so the street keeps moving past
The pane goes in cleanly, but pedestrians keep brushing past the trolley and one walks through the gap while you lift. Nobody is hurt, and everyone gets a fright.
Fetch the cups, cone off the footpath and lift it together
Andre fetches the cups, you cone off a bay of footpath and lift it between you. The glass goes in without a scratch, and a passer-by claps. Andre learns that taking the extra minute is always cheaper than replacing the glass.
How it went
By nine the shop has a secure window, a plan for the glass, and an owner who has stopped shaking. Glaziers work with heavy, fragile material and people on difficult days. Could you stay calm and steady when someone else is having a very bad morning?
This is a simplified, fictional situation to help you explore. It is not professional instruction or a test of your ability.
Case study: The pane that was a few millimetres out
A fictional case set in a glass and glazing company that fits windows, shopfronts, mirrors and shower screens, and answers emergency calls.
The situation
Chidi's glazing team was fitting a large window in a new cafe. The window had been ordered from the measurements on the builder's plans. When the glass arrived, Chidi checked the opening on site and found it was a few millimetres narrower than the plans said, because the frame had been built slightly off. The cafe owner, Annika, was opening in three days and had already printed invitations. The glass had taken two weeks to make.
What they did
Chidi did not force it and did not tell Annika it would be fine. He rang the builder, who agreed to check the frame. Together they worked out that the frame could be adjusted a little without affecting its strength, which the builder did that afternoon. Chidi remeasured before lifting the glass, fitted it with the right gaps all round and signed off only when he was satisfied that it was square.
How it turned out
The window went in the next morning. The cafe opened on time, and the window was the first thing visitors commented on. The builder and Chidi argued about whose measurement had been wrong, and agreed to measure twice on site on the next job.
What would you do?
- Why do you think it is so important to measure on site and not only on the plans?
- What could have gone wrong if Chidi had forced the glass in?
- How would you tell the owner there might be a delay?
