- Sealant that was laid over old silicone and failed
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
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 fails, we can still redo it.
About our glazing silicone in Highwood
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it, and if it’s something sealant cannot fix, we’ll tell you. We work on glass balustrade bases, conservatory frames and rooflights, and people most often call us about leaks from the base of a shower screen and cracked silicone between glass panels.
In a village or hamlet like Highwood, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Questions from Highwood
Do you cover smaller places like Highwood?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on glazing silicone in Highwood?
All our work, in Highwood and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
When is the sealant fully cured?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you reseal the base of a glass balustrade?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Can you just put new silicone over the old?
It does not last. The new bead cannot grip the old one, so we remove the old sealant and clean the joint.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We will tell you when we quote.
The process
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work normally takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Highwood, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

Glazing silicone in Highwood: local notes
Historic houses like Avon Tyrrell House (about 4.6 miles south) are a reminder that the area around Highwood 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. 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.
Homes close to St John the Baptist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Poulner Infant School, its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Highwood
Different surfaces, different methods
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
What affects the cost of glazing silicone
The price is agreed before any work begins. It takes into account:
- Access and height
- The type of sealant required
- Any working-time requirements on site
- Any mould that needs treating
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- The problem you’ve noticed
- The address or postcode of the job

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Open vents or windows to let moisture out
- Clear the conservatory gutters regularly
- Wipe the screen down after showering
- Do not use a blade near the sealant
Check the joints once a year. Catching a split early keeps the repair small.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Glass that needs replacing
- A sealed unit that has misted inside
- A sagging or failing conservatory roof
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Glass balustrade bases
- Conservatory frames
- Glass-to-glass joints
