How we handle glazing silicone in Heron Quays
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. Typical jobs include new silicone smeared over old sealant and black or yellowed silicone on glass joints, on glass balustrade bases, shower screens and rooflights.
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, in Heron Quays as anywhere.
Every job is covered by our 12-month guarantee.

Leave it or put it right?
Leaks get worse, not better. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Heron Quays.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Can I do it myself?
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:

FAQs for Heron Quays
I let a flat near Canary Wharf station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can you do glazing silicone in Heron Quays?
Yes, Heron Quays is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it possible to redo the silicone on a shower screen?
We can. The old bead comes off without marking the glass before cleaning and resealing.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Heron Quays.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Can you replace a misted double-glazed unit?
We don’t replace glass. We reseal the joints around it, and we will tell you if a unit looks like it has failed.
The process
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most jobs. In Heron Quays, 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.
- 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.
Before we arrive
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Related advice
What we’re called out for in Heron Quays
Some conservatory leaks are not sealant at all: broken panels, roof problems and blocked gutters can all let water in. We find the cause before we seal anything.
People usually contact us when they notice one of these:
- Sealant that was laid over old silicone and failed
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
- Shower screens leaking along the wall or tray
For an older house near a landmark such as St Peter's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Windows and doors in Heron Quays
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Canary Wharf station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like Seven Mills Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
