DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Glazing silicone for homes and businesses in West Wickham
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on conservatory frames, glass-to-glass joints and glass-to-frame joints, and people most often call us about black or yellowed silicone on glass joints and shower screens leaking along the wall or tray.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in West Wickham as anywhere.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What we do, step by step
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours for most jobs, and we explain the cure time before we leave. In West Wickham, 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 trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Getting ready for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

Why deal with it now?
Topping up old silicone can look like a fix, but silicone does not stick to silicone, and the leak usually returns. Cutting out and resealing properly lasts. 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 West Wickham, the repair is bigger than the sealant job would have been.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What glazing silicone looks like in West Wickham
With historic houses such as Addington Palace (about 1.6 miles south-west) nearby, there’s older building stock in the area around West Wickham 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Oak Lodge Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. West Wickham is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How the job changes by surface
Glass balustrade bases
The base of a glass balustrade is normally sealed. Failed sealant there lets water collect.
Shower screens
Mouldy or lifting sealant on a screen leaks. A full reseal sorts it.
Signs you need glazing silicone in West Wickham
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Keep an eye out for any of the following:
- Black or yellowed silicone on glass joints
- Silicone pulling away from the glass
- Leaking glazing joints on a rooflight
- A quick top-up bead that didn’t last
If you let a flat or house near West Wickham station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
What your quote should include
- What product goes in the joint
- Which colour the sealant will be
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
West Wickham questions
Can parking be tricky for a visit in West Wickham?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is West Wickham in your area for glazing silicone?
Yes. We work across London and the South East, and West Wickham is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Will resealing stop my conservatory leaking?
In many cases, as long as sealant is the cause. We trace the leak first, so you know what you’re paying for.
Do you fit new glass or sealed units?
We do not replace glass. We reseal the joints around it and can tell you if a unit seems to have gone.
What guarantee do I get?
You get our one-year guarantee on all our work.
Do you have insurance?
Yes. We are fully insured.
