About our glazing silicone in Aston
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. Common call-outs are for leaks from the base of a shower screen and a quick top-up bead that didn’t last, on rooflights, glass balustrade bases and glass-to-glass joints.
In a village or hamlet like Aston, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Landlord and commercial work in Aston
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Why it’s worth doing now in Aston
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames generally just need resealing. Around Aston, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many joints need doing, including the tidy-up. Somewhere as small as Aston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Mention any tricky access

Questions from Aston
What guarantee comes with glazing silicone in Aston?
All our work, in Aston and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Aston within the area you cover?
Yes, Aston is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where do you work from?
Mr Mastic is based in Crawley. We cover Aston and the rest of Oxfordshire, along with the rest of our area.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you just put new silicone over the old?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Is balustrade sealant something you do?
We can. The old sealant is removed and the joint resealed with a suitable product.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Aston homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Longworth House (about 3.4 miles south-east) are a reminder that the area around Aston 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.
Managing a site like Aston and Cote Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Clean glass with a mild cleaner and a soft cloth
- Wipe the screen down after showering
- Do not leave a drip for the next storm
- Check the silicone on glass every year or so
Do not use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we’ll find out which.
Signs you need glazing silicone in Aston
The wrong sealant is a common cause. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
Common reasons people contact us are:
- A quick top-up bead that didn’t last
- Mouldy sealant around glass panels
- Water escaping where a screen meets the wall
- Glazing silicone that has cracked or come away
If you live in an older home near Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
