A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
Glazing silicone in Brands Hill
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. Common call-outs are for stained, discoloured glazing silicone and a quick top-up bead that didn’t last, on shower screens, glass-to-glass joints and glass-to-frame joints.
Somewhere as small as Brands Hill, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

- Whether old sealant or filler has to be cut out

What to tell us for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Any access issues, like height or stairs
- Roughly how big the job is
- The type of property
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Windows and doors in Brands Hill
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Frogmore House (about 2.4 miles west) are a reminder that the area around Brands Hill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Michael include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Colnbrook Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Sunnymeads station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Around Brands Hill
Around Brands Hill, our work takes us to homes and buildings near Langley Grammar School, The Crown Public House And Attached Barn and Arthur Jacob Nature Reserve and the streets around them. The nearest railway station is Sunnymeads station, roughly 1.1 miles south-west. Well-known places in the area include Windsor Castle (2.8 miles west) and Museum of Eton Life (3.1 miles west). Not far away are Uxbridge Moor and Staines Reservoirs.
Keeping the joints in good condition
Looking after new joints is easy:
- Look over the glazing joints once a year
- Do not use a blade near the sealant
- Check the gutters above the glazing for debris
- Squeegee the shower screen after each use
Avoid scraping near the new silicone when you clean. A soft cloth or sponge is best.
Do not leave lifting or mouldy silicone on glazing. Peeling silicone lets water in behind and the leak gets worse.
Why it’s worth doing now in Brands Hill
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly, so you can call the right trade. Around Brands Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

FAQs for Brands Hill
Will you come out to Brands Hill?
Yes. Brands Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Sunnymeads station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Where do you work from?

Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Why not top up the existing silicone?
It doesn’t last. The new bead cannot grip the old one, so we remove the old sealant and clean the joint.
Is a special sealant needed for glass?
We pick a glazing silicone to suit the materials. Neutral-cure silicone is the usual choice.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Do I have to be there?

We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

How it works

- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
