How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on how many joints need doing. In a small place like Greatham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

Glazing silicone in Greatham, done properly
Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. We’re often asked to deal with a quick top-up bead that didn’t last and glazing silicone that has cracked or come away, on glass balustrade bases, glass-to-glass joints and rooflights.
Somewhere as small as Greatham, 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.

Do you need glazing silicone in Greatham?
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
Any of these means the joints need attention:
- Black or yellowed silicone on glass joints
- Failed joints on frameless glass
- Water getting into a conservatory at the joints
- Shower screens leaking along the wall or tray
For site and facilities teams at buildings such as Greatham Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Before you book anyone
- Whether they’re fully insured
- Whether the sealant suits the joint
- How long the guarantee is
- Is the old sealant removed completely?
Keeping the joints in good condition
So the new joints stay in good condition:
- Inspect the sealant on glazing annually
- Check the gutters above the glazing for debris
- Avoid scraping close to the bead
- Clean glass with a mild cleaner and a soft cloth
Squeegee a shower screen after each shower and let the room air. That slows mould growth on the bead.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we’ll find out which.
Different surfaces, different methods
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Glass balustrade bases
The base of a glass balustrade is generally sealed. When it fails, water can sit in the channel.

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Liss station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in.

Your questions about glazing silicone in Greatham
Will you come out to Greatham?
Yes. Greatham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Liss station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
What information do you need?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours, depending on how many joints need doing. We will tell you when we quote.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What we cannot put right
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Cracked or broken glass
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Water coming through the roof rather than a sealant joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Rooflights
- Glass-to-glass joints
- Glass-to-frame joints
- Shower screens
- Glass balustrade bases
- Conservatory frames
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
