Glazing & conservatory sealant in Coombe, Greater London
We cover Coombe for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- A quick top-up bead that didn’t last
- Stained, discoloured glazing silicone
- Water escaping where a screen meets the wall
What the job involves on each surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glazing silicone in Coombe, done properly
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We work on glass-to-glass joints, shower screens and glass-to-frame joints, and the jobs we see most are stained, discoloured glazing silicone and failed joints on frameless glass.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Questions from Coombe
Is parking a problem for a job in Coombe?
Parking in Coombe, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.

Windows and doors in Coombe
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Southside House (about 1.4 miles east) nearby, there’s older building stock in the area around Coombe as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Norbiton station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. As a London address, Coombe can be tricky for parking: let us know about parking bays, permits or a driveway.

Leave it or put it right?
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame so we choose a glazing silicone instead. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Coombe, the repair is bigger than the sealant job would have been.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Why book with us
- White, clear, grey or another colour, product permitting
- Trusted Arbo and Everbuild sealants
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator
Common problems we fix in Coombe
Shower screen silicone gets wet every day. Mould gets into it and the edges begin to peel.
If you can see any of these, it’s time to have the joints looked at:
- Silicone pulling away from the glass
- Black or yellowed silicone on glass joints
- Cracked silicone between glass panels
- Water escaping where a screen meets the wall
For site and facilities teams at buildings such as Coombe Hill Junior School, the mastic around its windows and doors needs looking after like any other building’s.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Structural problems with a conservatory roof
- A broken pane or roof panel
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

The process
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many joints need doing. In Coombe, 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.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Before we arrive
- Clear items away from the joints we’re working on
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

Related advice
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Ventilate the conservatory to cut condensation
- Check the gutters above the glazing for debris
- Avoid strong solvents on or near the sealant
- Run a squeegee over the glass when you’re done
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
