About our glazing silicone in Feltham
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. We work on glass-to-glass joints, glass balustrade bases and conservatory frames, and common reasons people get in touch are mouldy sealant around glass panels and glass-to-glass joints that have split.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Feltham.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before you notice. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Feltham, the repair is bigger than a sealant job.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Why book with us
- A 12-month guarantee on all work

- Homes, businesses and hotels

For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
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.
DIY sealant or a professional job?
If you’re 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 does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the job changes by surface
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
Conservatory frames
Exposed frame joints wear with the weather. A fresh bead seals them again.
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Structural problems with a conservatory roof
- Water coming through the roof rather than a sealant joint
- Cracked or broken glass
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Shower screens
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Glass-to-frame joints
- Glass-to-glass joints
FAQs for Feltham
Can you help a landlord with a rental near Feltham station?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is parking an issue for glazing silicone in Feltham?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you come to Feltham?
Yes, we do. Our applicators work in Feltham.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you fit new glass or sealed units?
We don’t replace glass. We reseal the joints around it and can tell you if a unit seems to have gone.
Can you match the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.

What affects the cost of glazing silicone
There’s no set price list. What we look at:
- The number and length of the joints
- The product the joint needs
- The old material and how stubborn it is
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. In Feltham, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

Glazing silicone in Feltham: local notes
Historic houses like Strawberry Hill House (about 3.5 miles east) are a reminder that the area around Feltham 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Christ Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Feltham station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. If you look after a building such as St Lawrence Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s.
