- The old material and how stubborn it is
- Whether the work is at height

Glazing silicone in Bromley, done properly
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. Typical jobs include silicone pulling away from the glass and water running down inside the glass, on rooflights, glass balustrade bases and glass-to-glass joints.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Different surfaces, different methods
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Rooflights
Rooflight leaks can come from the sealant or the roof. We find the cause first.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Windows and doors in Bromley
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Bromley Palace (about 0.3 miles east) nearby, there’s older building stock in the area around Bromley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as St Mark's Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. As a London address, Bromley can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as Church of St Peter and St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Landlord and commercial work in Bromley
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Use gentle products around the joints
- Open vents or windows to let moisture out
- Keep conservatory gutters clear of leaves
- Act on drips or damp patches early
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
Your questions about glazing silicone in Bromley
Can you do glazing silicone in Bromley?
Yes. We work across London and the South East, and Bromley is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Is parking an issue for glazing silicone in Bromley?
Parking in Bromley, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Bromley.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Can you replace a misted double-glazed unit?
That is not something we do. A misted unit has failed inside and needs replacing by a glazier.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
Is it enough to run a bead over the old sealant?
Topping up is a common cause of leaks. We remove the old silicone, clean the joint and reseal.
What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most jobs from start to finish. In a London area like Bromley, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
How to prepare
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
