Glazing silicone in North End, done properly
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points, and we reseal both. If you have stained, discoloured glazing silicone and silicone pulling away from the glass, we can put it right.
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 North End.
Every job comes with our 12-month guarantee.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most jobs, depending on how much there is to do. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- 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
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

Advice
Surface by surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. When it fails, water can sit in the channel.
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Avoid strong solvents on or near the sealant
- Do not leave a drip for the next storm
- Wipe the screen down after showering
- Keep air moving in the conservatory
On shower screens, wipe or squeegee after use and let the room air. It helps stop mould getting into the silicone.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Glass that needs replacing
- A sealed unit that has misted inside
- A frame that needs repairing or replacing
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
What we seal

Common questions in North End
I let a flat near Slade Green station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is North End in your area for glazing silicone?
Yes, North End is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
How long does glazing silicone take?
Most jobs take a few hours for most jobs. Your quote will say how long we expect yours to take.
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.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you fit new glass or sealed units?
No. We renew the sealant. A glazier replaces glass and units.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
North End homes and the weather
Historic houses like Hall Place and Gardens (about 2 miles south-west) are a reminder that the area around North End has older buildings as well as new. 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St. Augustine's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as St. Paul's (Slade Green) Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Slade Green station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
