Seething Wells Glazing Silicone
Our applicators work in Seething Wells on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly.
- A quick top-up bead that didn’t last
- Leaking glazing joints on a rooflight
- Black or yellowed silicone on glass joints
What happens if it’s left?
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames generally just need resealing. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
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, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

How we handle glazing silicone in Seething Wells
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. Common call-outs are for water tracking down the inner face of the glass and failed sealant around rooflight glass, on conservatory frames, rooflights and glass-to-glass joints.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
Each job carries a 12-month guarantee.

How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
How to prepare
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the cost of glazing silicone
Jobs vary more than people expect. What affects the quote:
- How many areas need sealing
- The type of sealant required
- Any mould that needs treating
- How easy the joints are to reach
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What we need to know
When you contact us, these details help:
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
If you are in Seething Wells and need glazing silicone, ring 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Glass that needs replacing
- Structural problems with a conservatory roof
- Water coming through the roof rather than a sealant joint
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Shower screens
- Glass-to-glass joints
- Rooflights

Seething Wells: your questions answered
Do you cover Seething Wells for glazing silicone?
Yes, Seething Wells is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is parking a problem for a job in Seething Wells?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
What does glazing silicone cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What information do you need?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
What the job involves on each surface
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
What glazing silicone looks like in Seething Wells
With historic houses such as Hampton Court Palace (about 1.3 miles north-west) nearby, there’s older building stock in the area around Seething Wells as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
Seething Wells is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Homes close to St Andrew'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. For site and facilities teams at buildings such as Maple Infants' School, the mastic around its windows and doors needs looking after like any other building’s.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep scrapers and blades away from the silicone
- Clean glass with a mild cleaner and a soft cloth
- Clear the conservatory gutters regularly
- Get a new leak looked at quickly
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
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.
