What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. In an older home around Brompton, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

About our glazing silicone in Brompton
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for shower screens leaking along the wall or tray and mouldy sealant around glass panels, across shower screens, rooflights and glass-to-frame joints.
In a smaller place like Brompton, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
We stand behind the work with a 12-month guarantee.

Expect the work to take a few hours for most jobs, and we tell you how long to leave it before we go.

Advice
Brompton homes and the weather
Brompton is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Brompton-Westbrook Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Chatham station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Brompton is about 1 mile east of Rochester, in Medway. Brompton gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

How to look after the new joints
To keep the joints looking good and working properly:
- Act on drips or damp patches early
- Check the gutters above the glazing for debris
- Check the silicone on glass every year or so
- Keep harsh solvents off the silicone
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
Surface by surface
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Glass-to-glass joints
These joints are on show, so we take care to leave a neat bead.

Questions from Brompton
Do you cover smaller places like Brompton?
Yes. Brompton is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is glazing silicone in a coastal place like Brompton any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once.
Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
Why not top up the existing silicone?
New silicone will not bond to old silicone and water gets between the layers. We cut out the old sealant first.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
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.
When to call us in Brompton
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
If you can see any of these, it’s time to have the joints looked at:
- Split or lifting silicone on glass
- Stained, discoloured glazing silicone
- Drips on the inside of a conservatory window
- Leaking glazing joints on a rooflight
For an older house near a landmark such as Brompton Garrison Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
