About our glazing silicone in Kingston Lisle
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. Typical jobs include new silicone smeared over old sealant and failed sealant around rooflight glass, on shower screens, conservatory frames and glass-to-frame joints.
Mastic can only go onto a dry, clean joint, so window work in Kingston Lisle is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Windows and doors in Kingston Lisle
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. Historic houses like Ashdown House (about 4.7 miles south-west) are a reminder that the area around Kingston Lisle has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In and around Kingston Lisle, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint. If you live in an older home near Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly, so you can call the right trade. In a small place like Kingston Lisle, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- Any old sealant cut out fully, not covered over
- 20+ years of sealant experience
- Sealant colour chosen to suit
- 4.9 on Google from 180+ five-star reviews

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A sealed unit that has misted inside
- A sagging or failing conservatory roof
- A frame that needs repairing or replacing
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours, depending on how many joints need doing. In a small place like Kingston Lisle, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Avoid scraping close to the bead
- Clean glass with a mild cleaner and a soft cloth
- Get a new leak looked at quickly
- Keep conservatory gutters clear of leaves
Follow the cure time we give you before the joints get wet. From then on, a mild glass cleaner is all it needs.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.

Kingston Lisle: your questions answered
Can you do glazing silicone in Kingston Lisle?
Yes. We work across London and the South East, and Kingston Lisle is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Is glazing silicone in Kingston Lisle guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Why not top up the existing silicone?
Silicone doesn’t stick to silicone, so a top-up soon lets water through. We cut out the old sealant first.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
How do I get a quote for glazing silicone in Kingston Lisle?

Different surfaces, different methods
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
