Do you need glazing silicone in Broom Hill?
Glass and frames expand and contract with the temperature at different rates. Over years, that movement tears the silicone.
The problems people normally mention when they call are:
- Water escaping where a screen meets the wall
- Water running down inside the glass
- Split or lifting silicone on glass
- New silicone smeared over old sealant
As a London address, Broom Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

About our glazing silicone in Broom Hill
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on shower screens, rooflights and glass-to-glass joints, and common reasons people get in touch are stained, discoloured glazing silicone and failed sealant around rooflight glass.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
There’s a 12-month guarantee on every job.

How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from an hour or two to most of a day, depending on the size of the job. In Broom Hill, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Stick to mild cleaners on glass
- Keep harsh solvents off the silicone
- Wipe the screen down after showering
- Keep air moving in the conservatory
Follow the cure time we give you before the joints get wet so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.
What sealant work cannot fix
We will always be straight with you, so here’s what sealant cannot fix:
- Rotten or badly damaged frames
- Cracked or broken glass
- A sealed unit that has misted inside
If in doubt, call 0345 464 0079 or email us and we will say what we think.
What we seal
- Glass-to-glass joints
- Glass-to-frame joints
- Glass balustrade bases
- Conservatory frames
- Rooflights
- Shower screens
Different surfaces, different methods
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Glass balustrade bases
The base joint is cut out and resealed. Glass fitting is a separate trade.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
FAQs for Broom Hill
I let a flat near Orpington station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is parking an issue for glazing silicone in Broom Hill?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Which silicone is used for glass joints?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Broom Hill, along with the rest of our area.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
What glazing silicone looks like in Broom Hill
Historic houses like Bromley Palace (about 3.7 miles north-west) are a reminder that the area around Broom Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
If you look after a building such as Perry Hall Primary School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Orpington station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
