Glazing silicone for homes and businesses in Mitcham
We don’t replace glass, and misting between panes means a failed sealed unit. What we do is the silicone around the glass, which is where many leaks start. If you are dealing with failed sealant around rooflight glass and water tracking down the inner face of the glass, we can put it right, on shower screens, glass balustrade bases and glass-to-frame joints alike.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
All our work comes with our one-year guarantee, wherever you are in Greater London.

Windows and doors in Mitcham
Historic houses like Southside House (about 3.6 miles west) are a reminder that the area around Mitcham has older buildings as well as new. In older buildings, 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.
Mitcham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near St. Mark's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Signs you need glazing silicone in Mitcham
The wrong sealant is a common cause. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
If you can see any of these, it’s time to have the joints looked at:
- Failed sealant around rooflight glass
- Drips on the inside of a conservatory window
- Leaks from the base of a shower screen
- Black or yellowed silicone on glass joints
Managing a site like St Thomas of Canterbury Catholic Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Related advice
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Clear the conservatory gutters regularly
- Squeegee the shower screen after each use
- Clean glass with a mild cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.

Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully before cleaning and resealing.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you replace a misted double-glazed unit?
Glass replacement is not our trade. We look after the sealant joints, and we’ll tell you if a unit looks like it has failed.

Leave it or put it right?
Resealing cannot fix a failed unit or a cracked panel. We will tell you that rather than seal it anyway and point you to a glazier or roofer. Converted houses in London often have a bathroom above someone else’s living room, 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 for homes in Mitcham.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
