Glazing silicone for homes and businesses in Merton
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 cut it out and reseal with a glazing silicone suited to the joint. We’re often asked to deal with glass-to-glass joints that have split and leaking glazing joints on a rooflight, on glass-to-frame joints, glass-to-glass joints and glass balustrade bases.
Somewhere as small as Merton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job.

How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Merton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Advice
Different surfaces, different methods
Rooflights
Water around a rooflight isn’t always the sealant. We find the cause first.
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Merton: your questions answered
I let a flat near Bicester Village station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Merton within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.
Do you reseal glass shower screens?
Yes. The old bead comes off without marking the glass before cleaning and resealing.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Structural problems with a conservatory roof
- A sealed unit that has misted inside
- Frames that have decayed or split
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal
- Shower screens
- Glass-to-frame joints

Frames and glazing around Merton
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Boarstall Tower (about 3.7 miles south-east) are a reminder that the area around Merton 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.
Homes close to Church of St Swithin include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Bicester Village station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Why deal with it now?
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before you notice. In a small place like Merton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Aftercare tips
To keep the joints looking good and working properly:
- Act on drips or damp patches early
- Avoid strong solvents on or near the sealant
- Run a squeegee over the glass when you are done
- Ventilate the conservatory to cut condensation
Follow the cure time we give you before the joints get wet. 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 before you spot it.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
