About our glazing silicone in Blackheath
We do not replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass and that’s often where the water gets in. If you have water running down inside the glass and failed sealant around rooflight glass, we can put it right.
Somewhere as small as Blackheath, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in Blackheath as everywhere else we work.

The process
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job in most cases. In a small place like Blackheath, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

What happens if it’s left?
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Where a wall is exposed, as many are in small places like Blackheath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Why Blackheath customers choose us
- A 12-month guarantee on all work
- Rated 4.9 stars on Google
- Trusted Arbo and Everbuild sealants
- White, clear, grey or coloured to suit, where the product allows
Looking after it afterwards
Looking after new joints is easy:
- Ventilate the conservatory to cut condensation
- Run a squeegee over the glass when you are done
- Keep harsh solvents off the silicone
- Get a new leak looked at quickly
Don’t use blades or scrapers near the bead when you clean. Stick to a soft cloth.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.
Questions from Blackheath
Can you do glazing silicone in Blackheath?
Yes, Blackheath is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Chilworth station?

Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames, as some acetoxy types can attack certain metals.
What does glazing silicone cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.

In fairness, there are a few things sealant won’t fix:
- A frame that needs repairing or replacing

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

What the job involves on each surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.

Blackheath homes and the weather
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. With historic houses such as Chilworth Manor (about 1.1 miles north) nearby, there’s older building stock in the area around Blackheath 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’s traditional sand mastic.
If you live in an older home near Church of St Martin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Chilworth CofE (Aided) Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Chilworth station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
