Glazing silicone in Smithfield, done properly
Across Smithfield, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method, with a sealant chosen for the joint. We work on glass-to-frame joints, shower screens and rooflights, and people most often call us about leaking glazing joints on a rooflight and mouldy sealant around glass panels.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Smithfield: your questions answered
Do you work for landlords with property near Farringdon station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Can you do glazing silicone in Smithfield?
Yes. We work across London and the South East, and Smithfield is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
How long before the joint can be used?
It depends on the product. We tell you how long to leave it before we go.
Do you replace glass?
No. We renew the sealant. Glass and sealed units need a glazier.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What guarantee do I get?
Our 12-month guarantee applies on all our work.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
What affects the cost of glazing silicone
Call for a quick quote. What matters most is:
- The number and length of the joints
- How easy the joints are to reach
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Where the property is
- Roughly how big the job is
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or drop us an email with the details.

Should I try it myself first?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Leave it or put it right?
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. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Smithfield, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work starts. Most jobs take a few hours, depending on how many joints need doing.

- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

Signs you need glazing silicone in Smithfield
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.
Any of these means the joints need attention:
- Split or lifting silicone on glass
- Water escaping where a screen meets the wall
- Glass-to-glass joints that have split
- Mouldy sealant around glass panels
For an older house near a landmark such as St Bartholomew-the-Less, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Glazing silicone in Smithfield: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
If you look after a building such as Charterhouse Square School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Farringdon station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
