About our glazing silicone in Sewardstone
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on glass balustrade bases, shower screens and conservatory frames, and people most often call us about water tracking down the inner face of the glass and leaks from the base of a shower screen.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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 doesn’t work out, we can still put it right.

Windows and doors in Sewardstone
With historic houses such as Forty Hall (about 2.8 miles west) nearby, there’s older building stock in the area around Sewardstone as well as newer homes. 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. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Letting a property close to Enfield Lock station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as Prince of Wales Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Sewardstone is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Where we work in Sewardstone
- Shower screens
- Rooflights
- Glass balustrade bases
- Conservatory frames
- Glass-to-glass joints
- Glass-to-frame joints
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Use a gentle glass cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
- Run a squeegee over the glass when you are done
Do not use blades or scrapers near the bead when you clean. Stick to a soft cloth.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
Common questions in Sewardstone
Is parking an issue for glazing silicone in Sewardstone?
Parking in Sewardstone, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do you work for landlords with property near Enfield Lock station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
How much does glazing silicone cost in Sewardstone?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you fit new glass or sealed units?
No. We renew the sealant. Glass and sealed units need a glazier.
Will resealing stop my conservatory leaking?
Often, if the leak is at a sealant joint. We find where the water gets in first, so you know what you are paying for.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. Fresh silicone will not bond to cured silicone so we take it all out and start clean.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it possible to redo the silicone on a shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Landlord and commercial work in Sewardstone
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Quotes for glazing silicone in Sewardstone
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- The number and length of the joints
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- Whether it has been sealed before
- The address or postcode of the job
- Any access issues, like height or stairs
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.
What happens if it’s left?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for most jobs. In Sewardstone, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- Mention any tricky access
