Glazing silicone in Southborough, done properly
Across Southborough, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. If you have cracked silicone between glass panels and water tracking down the inner face of the glass, we can help, whatever the surface.
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, and access in Southborough is something to talk through when you book.
Big or small, it’s backed by our 12-month guarantee.

Southborough homes and the weather
Compared with the north and west, the South East gets less rain, 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 1.4 miles north-west) nearby, there’s older building stock in the area around Southborough as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Southborough is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near St Augustine's Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Bickley station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Leaks from the roof covering or flashing (a roofer’s job)
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Frames that have decayed or split
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

How the job changes by surface
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. We reseal them with a sealant suited to the frame.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Act on drips or damp patches early
- Clear the conservatory gutters regularly
- Check the silicone on glass every year or so
- Keep harsh solvents off the silicone
Don’t use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours, depending on how many joints need doing, depending on the size of the job. In Southborough, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Clear items away from the joints we are working on

Your questions about glazing silicone in Southborough
Do you work for landlords with property near Bickley station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can parking be tricky for a visit in Southborough?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. The new bead can’t grip the old one so we take it all out and start clean.
Do you guarantee glazing sealant work?
Our 12-month guarantee applies on all our work.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it possible to redo the silicone on a shower screen?
We can. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
