About our glazing silicone in Bellingham
Glazing silicone is a maintenance item. Sun, rain and movement wear it down, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. We are often asked to deal with water escaping where a screen meets the wall and leaks where conservatory glass meets the frame, on rooflights, glass-to-glass joints and glass balustrade bases.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Bellingham
Shower screen silicone gets wet every day. Mould gets into it and the edges begin to peel.
Keep an eye out for these signs:
- New silicone smeared over old sealant
- Leaking glazing joints on a rooflight
- Water running down inside the glass
- Black or yellowed silicone on glass joints
Homes close to St Dunstan include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Bellingham: your questions answered
Is Bellingham in your area for glazing silicone?
Yes, Bellingham is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Do you work for landlords with property near Bellingham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do you seal glass balustrade bases?
Yes, we reseal the joint at the base channel. Fitting glass is a separate trade.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before we start.
Is it possible to redo the silicone on a shower screen?
We can. We remove the old silicone carefully, and the joints are cleaned and resealed.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- A sagging or failing conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
- A broken pane or roof panel
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Glass balustrade bases
- Conservatory frames
- Glass-to-frame joints
- Shower screens
- Rooflights
- Glass-to-glass joints
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What glazing silicone looks like in Bellingham
With historic houses such as Kingswood House (about 2.5 miles west) nearby, there’s older building stock in the area around Bellingham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Bellingham is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Elfrida Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Bellingham is about 2 miles north of Beckenham, in Greater London. We provide glazing silicone to homes and businesses in Bellingham and nearby. Bellingham is one of 764 places in Greater London where we work for glazing silicone. We also work in London, around 6 miles away.
Jobs for glazing silicone in SE6, SE26 and SE23 works the same way as everywhere else we cover. You’ll find streets such as Oslac Road, Orford Road and Aitken Road, all of which we cover. You’ll find Bellingham on the A2218, so it’s easy for us to get to. Close by, we work in Southend (1 mile north), Bell Green (1 mile west), Catford (1 mile north-east), Perry Vale (1 mile west) and Sydenham (1 mile west). We also work in nearby towns such as London (6 miles north-west), City of Westminster (8 miles north-west), Marylebone (8 miles north-west), Kensington (9 miles north-west), St Pancras (8 miles north-west) and Shoreditch (7 miles north).
Local landmarks in Bellingham
Around Bellingham, our work takes us to homes and buildings near Sedgehill School, Forster Memorial Park and Allenby Tutorial Trust, among other places. There’s a railway station in Bellingham itself: Bellingham station. A little further out are Prefab Museum (1 mile east) and University Hospital Lewisham (1.6 miles north). For a walk, there’s Downham Woodland Walk and Knight's Hill.
How to look after the new joints
After the cure time, these simple habits help:
- Ventilate the conservatory to cut condensation
- Avoid scraping close to the bead
- Run a squeegee over the glass when you are done
- Get a new leak looked at quickly
Keep the new joints dry for as long as we advise so the silicone can set properly. After that, clean glass with a mild cleaner.
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.
What happens if it’s left?
Topping up old silicone can look like a fix, but silicone does not stick to silicone and water soon finds its way back. Cutting out and resealing properly lasts. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Bellingham, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows

- ARBOMaster approved applicator
What affects the cost of glazing silicone
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Access and height
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- The type of property
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or drop us an email.
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on how many joints need doing. In Bellingham, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
