Glazing silicone for homes and businesses in Ashtead
Glass and frames expand and contract differently, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. Common call-outs are for split or lifting silicone on glass and water running down inside the glass, across shower screens, rooflights and glass-to-frame joints.
Ashtead mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. All of them depend on a sound bead of mastic between frame and wall.
A 12-month guarantee comes as standard.

What affects the cost of glazing silicone
For a quick quote, just ask. The main things that affect it are:
- Whether there’s mould to deal with
- The number of rooms or windows
- The type of sealant required
- The size of the job
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
When you contact us, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- Where the job is, and your postcode
- A few photos by email, if you can
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.

What else we do in Ashtead
Why act early in Ashtead
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames normally just need resealing. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Ashtead homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Fitznells Manor (about 3.7 miles north-east) are a reminder that the area around Ashtead has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Ashtead station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Parsons Mead School, its window and door frames need their mastic kept sound, just like a home’s.

Common problems we fix in Ashtead
Not every leak is a sealant problem: broken panels, roof problems and blocked gutters can all let water in. That is why we trace the leak first.
Look out for any of the following:
- Leaking glazing joints on a rooflight
- A quick top-up bead that didn’t last
- Water escaping where a screen meets the wall
- Mouldy sealant around glass panels
If you live in an older home near St George's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
