What affects the cost of glazing silicone
Your quote is based on your job. We look at:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- Access and height
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
To help us quote quickly, let us know:
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- What’s wrong with the joints now
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.
About our glazing silicone in Southwark
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. If you are dealing with glazing silicone that has cracked or come away and conservatory leaks at frame and glazing joints, we can help.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Southwark.
Your job is guaranteed for a year, as with all our work.

Questions from Southwark
Can you do glazing silicone in Southwark?
Yes, Southwark is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Can you help a landlord with a rental near Elephant & Castle station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Can you just put new silicone over the old?
New silicone won’t bond to old silicone and water gets between the layers. The old bead always comes out first.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
What happens if it’s left?
Replacing windows or a shower screen is not needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Why us?
- More than 20 years in sealant work
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
- Anti-fungal sanitary silicone in wet areas

Landlords and agents in Southwark can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Frames and glazing around Southwark
Historic houses like Mansion House (about 0.9 miles north) are a reminder that the area around Southwark 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Charles Dickens Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. As a London address, Southwark can be tricky for parking: let us know about parking bays, permits or a driveway. In the older streets around Borough Welsh Congregational Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In Southwark, 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 find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
