Glazing silicone in Kingston, done properly
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it and tell you plainly if the cause is something else. If you’re dealing with water running down inside the glass and leaking glazing joints on a rooflight, we can put it right, whatever the surface.
Somewhere as small as Kingston, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same one-year guarantee in Kingston and across Kent.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Kingston questions
Is Kingston within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Adisham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
Can you replace a misted double-glazed unit?
We do not replace glass. We reseal the joints around it, and we’ll tell you if a unit looks like it has failed.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Glazing silicone in Kingston: local notes
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. With historic houses such as Goodnestone Park (about 3.8 miles north-east) nearby, there’s older building stock in the area around Kingston as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Barham Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Giles, the joint between an old wall and a newer frame is usually the first place rain gets in.
Kingston is about 5 miles south-east of Canterbury, in Kent. From the centre of Kingston to the outskirts, glazing silicone is available for homes and businesses alike. Kingston is one of 922 towns and villages in Kent where we work. You can also see our page for Chelmsford, about 46 miles away.
Every address in CT4 is covered for glazing silicone, from the main roads to the quietest streets. If you need glazing silicone at a property on The Street, Church Lane and Covet Lane or a nearby road, our applicators can take on the job. We also cover the places around Kingston: Out Elmstead (1 mile south-east), Barham (1 mile south-east), Marley (1 mile south-west), Bishopsbourne (1 mile north-west) and Derringstone (1 mile south). Within a short drive, we also cover Ashford (13 miles south-west), Canterbury (5 miles north-west), Margate (15 miles north-east), Dover (9 miles south-east), Folkestone (9 miles south) and Ramsgate (14 miles north-east).
What’s near Kingston
Typical jobs here are in homes near Black Robin Public House and Jumping Downs and the streets around them. The nearest railway station is Adisham station, roughly 2.7 miles north-east. A little further out are Kent and Canterbury Hospital (4.2 miles north-west).
What we cannot put right
We’ll always be straight with you, so here’s what sealant cannot fix:
- A broken pane or roof panel
- Structural problems with a conservatory roof
- A frame that needs repairing or replacing
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Glass-to-glass joints
- Glass-to-frame joints
- Glass balustrade bases
- Shower screens
- Rooflights
- Conservatory frames
Common problems we fix in Kingston
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Keep an eye out for these signs:
- Water escaping where a screen meets the wall
- Glass-to-glass joints that have split
- Black or yellowed silicone on glass joints
- Leaking glazing joints on a rooflight
If you let a flat or house near Adisham station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Questions to ask before booking
- Who turns up on the day
- Whether VAT is included
- What happens if the job turns out different
- How the colour is chosen
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Clear the conservatory gutters regularly
- Run a squeegee over the glass when you are done
- Keep harsh solvents off the silicone
- Clean glass with a mild cleaner and a soft cloth
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
How it works
Once we’re on site, we check the joints match what you told us. 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. For a village or hamlet like Kingston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
Ask for a quote
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or drop us an email.
Advice
Landlord and commercial work in Kingston
If you manage several properties in or around Kingston, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Why act early in Kingston
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames normally just need resealing. In a small place like Kingston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
