Glazing silicone in Blackgang
Glazing silicone is a maintenance item. Weather and movement take their toll and cracked joints let water in. Renewing it keeps glazing joints doing their job. We work on glass-to-frame joints, rooflights and conservatory frames, and common reasons people get in touch are sealant that was laid over old silicone and failed and failed joints on frameless glass.
In a village or hamlet like Blackgang, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee.

What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. In a small place like Blackgang, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Blackgang: your questions answered
Is Blackgang in your area for glazing silicone?
Yes. We work across London and the South East, and Blackgang is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Do you cover smaller places like Blackgang?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Is it possible to redo the silicone on a shower screen?
We can. We remove the old silicone carefully, and the joints are cleaned and resealed.
How long does the job take?
Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Your quote will say how long we expect yours to take.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Looking after it afterwards
So the new joints stay in good condition:
- Get a new leak looked at quickly
- Stick to mild cleaners on glass
- Inspect the sealant on glazing annually
- Avoid strong solvents on or near the sealant
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.

How it works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many joints need doing.

Advice
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When it is not the sealant
It helps to know what we can’t do:
- A frame that needs repairing or replacing
- Water coming through the roof rather than a sealant joint
- A roof that has moved or dropped
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Where we work in Blackgang
- Conservatory frames
- Glass-to-frame joints
- Glass balustrade bases
- Shower screens
- Glass-to-glass joints
- Rooflights
Different surfaces, different methods
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Glass balustrade bases
The base of a glass balustrade is usually sealed. Failed sealant there lets water collect.
Windows and doors in Blackgang
Blackgang is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on glazing joints and frame seals, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Niton Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Andrew's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
