Glazing Silicone in Addiscombe
Glazing silicone for conservatories, rooflights, glass panels and shower screens for householders, landlords and businesses in Addiscombe. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Split or lifting silicone on glass
- Shower screens leaking along the wall or tray
- Failed joints on frameless glass
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clear the conservatory gutters regularly
- Don’t use a blade near the sealant
- Keep harsh solvents off the silicone
- Wipe the screen down after showering
Squeegee a shower screen after each shower and keep the room ventilated. That slows mould growth on the bead.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
Glazing silicone for homes and businesses in Addiscombe
Frameless shower screens rely on sealant to keep water in. Leaks usually come from the wall joint or the tray joint and both get fresh anti-fungal silicone. If you are dealing with shower screens leaking along the wall or tray and water tracking down the inner face of the glass, we can help, on glass-to-frame joints, glass-to-glass joints and shower screens alike.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking, and access in Addiscombe is something to talk through when you book.

What affects the cost of glazing silicone
The price is agreed before any work begins. It takes into account:
- Working hours on commercial sites
- How many areas need sealing
- How much there is to do
- Access and height
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- A few pictures by email, if you can
- Any access issues, like height or stairs
- The address or postcode of the job
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before we start.
Windows and doors in Addiscombe
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. 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.
Schools such as Oasis Academy Shirley Park are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St Mildred's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Addiscombe is about 2 miles north-east of Croydon, in Greater London. We provide glazing silicone to homeowners, landlords and businesses in Addiscombe and the surrounding area. Our Greater London coverage runs to 764 places, Addiscombe among them. London is on our list too, around 8 miles away.
Every address in CR0, SE25 and CR9 is covered for glazing silicone. If you need glazing silicone at a property on Grant Road, Capri Road and Coe Avenue or a nearby road, we can help.

Common problems we fix in Addiscombe
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
If you can see any of these, it’s time to have the joints looked at:
- Water running down inside the glass
- Cracked silicone between glass panels
- Mouldy sealant around glass panels
- Silicone pulling away from the glass
Addiscombe is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- What insurance they hold
- When the joint can take water or movement
- Whether the sealant suits the joint
- Whether VAT is included
Your questions about glazing silicone in Addiscombe
Can you do glazing silicone in Addiscombe?
Yes. Our work covers London and the South East, and Addiscombe is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Norwood Junction station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Which silicone is used for glass joints?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
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.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Why act early in Addiscombe
Replacing windows or a shower screen isn’t needed for a failed joint. Sound glass and frames usually just need resealing. In a flat in Addiscombe, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.
Why choose Mr Mastic in Addiscombe
- Approved under the ARBOMaster scheme
- Fully insured
- Arbo and Everbuild products
- Sanitary silicone with an anti-fungal additive in wet areas

For landlords and businesses
We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
