Leave it or put it right?
A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If it’s the roof itself, we’ll tell you. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
What you get with us
- Anti-fungal silicone where joints get wet
- 180+ five-star Google reviews

- Any old sealant cut out fully, not covered over
How we handle glazing silicone in Walthamstow
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. We work on glass balustrade bases, glass-to-frame joints and shower screens, and people most often call us about water tracking down the inner face of the glass and conservatory leaks at frame and glazing joints.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Walthamstow is something to talk through when you book.
Every job comes with our 12-month guarantee.

Surface by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Look over the glazing joints once a year
- Use a gentle glass cleaner and a soft cloth
- Keep conservatory gutters clear of leaves
- Do not use a blade near the sealant
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
What glazing silicone looks like in Walthamstow
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. 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.
If you let a flat or house near Walthamstow Central station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Walthamstow is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Greenleaf Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Should I try it myself first?
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.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Walthamstow: your questions answered
Is parking an issue for glazing silicone in Walthamstow?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you cover Walthamstow for glazing silicone?
Yes, Walthamstow is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you reseal a frameless shower screen?
Yes, it’s a common job. The screen is resealed with anti-fungal silicone made for wet areas.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most jobs, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Walthamstow. A visitor permit or a nearby bay makes the visit run more smoothly.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
