For a village or hamlet like Five Ash Down, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

How we handle glazing silicone in Five Ash Down
We work across Five Ash Down on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We work on shower screens, glass-to-frame joints and glass balustrade bases, and common reasons people get in touch are failed joints on frameless glass and water escaping where a screen meets the wall.
Somewhere as small as Five Ash Down, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Five Ash Down homes and the weather
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.
For site and facilities teams at buildings such as Buxted CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Five Ash Down Independent Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Five Ash Down
Can you help a landlord with a rental near Buxted station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is Five Ash Down in your area for glazing silicone?
Yes. We work across London and the South East, and Five Ash Down is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Can you replace a misted double-glazed unit?
That is not something we do. A misted unit has failed inside and needs replacing by a glazier.
Can you just put new silicone over the old?
A top-up rarely holds. Fresh silicone won’t bond to cured silicone so we take it all out and start clean.
Where do you work from?
Mr Mastic is based in Crawley. We cover Five Ash Down and the rest of East Sussex, along with the rest of our area.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure silicone is the usual choice.
Do you need glazing silicone in Five Ash Down?
Using a sealant not made for glass causes many failures. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
People normally contact us after spotting one of these:
- Conservatory leaks at frame and glazing joints
- Split or lifting silicone on glass
- Sealant that was laid over old silicone and failed
- Stained, discoloured glazing silicone
For landlords with property near Buxted station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Surface by surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.
Why deal with it now?
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. Older cottages and farmhouses around Five Ash Down can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Rated 4.9 stars on Google
- Over 20 years’ experience
- Any old sealant cut out fully, not covered over
- Colour agreed with you before work begins
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear the conservatory gutters regularly
- Look over the glazing joints once a year
- Act on drips or damp patches early
- Keep air moving in the conservatory
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.

What else we do in Five Ash Down
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
