How we handle glazing silicone in Graffham
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. Typical jobs include split or lifting silicone on glass and sealant that was laid over old silicone and failed, across glass-to-frame joints, shower screens and rooflights.
Somewhere as small as Graffham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You get a 12-month guarantee, the same in Graffham as everywhere else we work.

Graffham questions
Can you do glazing silicone in Graffham?
Yes. Our work covers London and the South East, and Graffham is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
What guarantee comes with glazing silicone in Graffham?
All our work, in Graffham and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
How do I get a quote for glazing silicone in Graffham?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Will resealing stop my conservatory leaking?
That depends where the water is getting in. Sealant joints we can renew but roof and panel problems need another trade.
Can landlords and businesses book you?
Yes, regularly. Several properties can go on one quote.
Where do you work from?
Mr Mastic is based in Crawley. We cover Graffham and the rest of West Sussex.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
How to look after the new joints
Looking after new joints is easy:
- Act on drips or damp patches early
- Do not use a blade near the sealant
- Check the silicone on glass every year or so
- Stick to mild cleaners on glass
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
Landlord and commercial work in Graffham
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 that we can handle for you.
If you manage several properties in or around Graffham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
When it is not the sealant
It helps to know what we can’t do too:
- Glass that needs replacing
- A sealed unit that has misted inside
- Structural problems with a conservatory roof
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
- Rooflights
- Glass-to-glass joints
- Shower screens
- Glass-to-frame joints
- Glass balustrade bases
- Conservatory frames
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why deal with it now?
A new conservatory roof is a big job. If the leak is a failed sealant joint renewing the joint is the simpler fix. If the roof is the problem, we’ll say so. Where a wall is exposed, as many are in small places like Graffham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- An ARBOMaster approved applicator
- A choice of colours where the product allows
- Tidy, careful work
- Experience in homes, commercial sites and hotels

Windows and doors in Graffham
Historic houses like Cowdray House (about 3.5 miles north-west) are a reminder that the area around Graffham has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you look after a building such as Graffham CofE Infant School, the mastic around its windows and doors needs looking after like any other building’s.

Do you need glazing silicone in Graffham?
Glass and frames expand and contract with the temperature, and they do not move by the same amount. In time, the sealant splits or pulls away.
Common reasons people contact us are:
- New silicone smeared over old sealant
- Water running down inside the glass
- Rooflight joints letting water in
- Stained, discoloured glazing silicone
If you live in an older home near The Parish Church of St Giles, the joint between an old wall and a newer frame is generally the first place rain gets in.
