How we handle glazing silicone in Strawberry Hill
Frameless shower screens rely on sealant to keep water in. Leaks usually come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Typical jobs include shower screens leaking along the wall or tray and cracked silicone between glass panels, on glass balustrade bases, rooflights and shower screens.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. It will not solve:
- A sealed unit that has misted inside
- Water coming through the roof rather than a sealant joint
- A broken pane or roof panel
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What glazing silicone looks like in Strawberry Hill
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Strawberry Hill House (about 0.1 miles south-west) nearby, there’s older building stock in the area around Strawberry Hill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
As a London address, Strawberry Hill can be tricky for parking: let us know about parking bays, permits or a driveway. For an older house near a landmark such as Holy Trinity Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
Strawberry Hill is about 1 mile south of Twickenham, in Greater London. Anywhere in TW1, our applicators can take on glazing silicone. Strawberry Hill is one of 764 towns and villages in Greater London where we work for glazing silicone. We also work in London, about 11 miles from Strawberry Hill.

Different surfaces, different methods
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Glass-to-glass joints
You see these joints clearly, so a straight, even finish matters.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Why act early in Strawberry Hill
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. In a flat in Strawberry Hill, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

What we are called out for in Strawberry Hill
Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
These are the problems we are asked about most:
- New silicone smeared over old sealant
- Silicone pulling away from the glass
- Mouldy sealant around glass panels
- Shower screens leaking along the wall or tray
If you look after a building such as Kneller Hall Senior School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Who does the work, and how experienced they are
- How long the guarantee is
- What the quote includes, VAT included or not
- When the joint can take water or movement
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
How it works
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours, depending on how many joints need doing, depending on the amount of work. In a London area like Strawberry Hill, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we agree the joints to be done.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
Ask for a quote
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job.
