Questions from Petersham
Do you cover Petersham for glazing silicone?
Yes, Petersham is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you work for landlords with property near St Margarets (London) station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Do you fit new glass or sealed units?
No. We renew the sealant. Glass and sealed units need a glazier.
Can you fix a leaking conservatory?
That depends where the water is getting in. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.
Is a special sealant needed for glass?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone with anti-fungal products in bathrooms.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Glazing silicone for homes and businesses in Petersham
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 is often where the water gets in. Typical jobs include water getting into a conservatory at the joints and cracked silicone between glass panels, on conservatory frames, shower screens and glass-to-glass joints.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
A one-year guarantee comes as standard.

What the job involves on each surface
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
Rooflights
Water around a rooflight is not always the sealant. We find the cause first.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid scraping close to the bead
- Clean glass with a mild cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
- Inspect the sealant on glazing annually
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
Why deal with it now?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Petersham homes and the weather
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St Peter's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to St Margarets (London) station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Petersham is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

The process
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to most of a day, depending on the size of the job, depending on the amount of work. In Petersham, 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.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
