DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How we handle glazing silicone in Lenham Forstal
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We work on rooflights, glass balustrade bases and conservatory frames, and common reasons people get in touch are sealant that was laid over old silicone and failed and failed sealant around rooflight glass.
Somewhere as small as Lenham Forstal, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
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.

Different surfaces, different methods
Glass-to-frame joints
We cut the old silicone from the glass without scratching it before new glazing silicone goes in.
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Lenham Forstal needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Mention if the joints have been sealed before

What affects the cost of glazing silicone
You will get a clear quote before we start. It takes into account:
- Access and height
- Whether there’s mould to deal with
- The size of the job
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- A few photos by email, if you can
- How we’d reach the joints
- The type of property
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What we cannot put right
It helps to know what we can’t do:
- A frame that needs repairing or replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Leaks from the roof covering or flashing (a roofer’s job)
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Do you fit new glass or sealed units?

Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
What sealant do you use on glazing?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Why not top up the existing silicone?
It does not last. The new bead cannot grip the old one, so we remove the old sealant and clean the joint.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Check the silicone on glass every year or so
- Avoid strong solvents on or near the sealant
- Run a squeegee over the glass when you are done
- Clear the conservatory gutters regularly
Clear the conservatory gutters regularly so water does not back up against the seals. Overflowing gutters can cause leaks of their own.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
Glazing silicone in Lenham Forstal: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as The Lenham School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The problems people usually mention when they call include:
- Water escaping where a screen meets the wall
- Rooflight joints letting water in
- Glazing silicone that has cracked or come away
- New silicone smeared over old sealant
Letting a property close to Lenham station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
