About our glazing silicone in St Margarets
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. Typical jobs include conservatory leaks at frame and glazing joints and glazing silicone that has cracked or come away, across glass balustrade bases, conservatory frames and glass-to-frame joints.
In a village or hamlet like St Margarets, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, you get the same one-year guarantee in St Margarets and across Hertfordshire.

Frame joints face sun and rain all year. Renewed sealant keeps water out.
FAQs for St Margarets
Can you do glazing silicone in St Margarets?
Yes. We work across London and the South East, and St Margarets is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Will you come out to St Margarets?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Can you fix a leaking conservatory?
It depends on the cause. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long will you be here?
A typical job takes a few hours, depending on how many joints need doing, including the preparation. Your quote will say how long we expect yours to take.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep conservatory gutters clear of leaves
- Stick to mild cleaners on glass
- Don’t leave a drip for the next storm
- Avoid scraping close to the bead
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
Windows and doors in St Margarets
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like The Cranbourne Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Parish Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Water coming through the roof rather than a sealant joint
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A roof that has moved or dropped
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Landlords, agents and businesses in St Margarets
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
From a single let to 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?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What we’re called out for in St Margarets
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
People normally contact us when they notice one of these:
- Rooflight joints letting water in
- Water tracking down the inner face of the glass
- Water escaping where a screen meets the wall
- Failed joints on frameless glass
For landlords with property near St Margarets (Herts) station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
