How we handle glazing silicone in Compton
Glass and frames expand and contract differently, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We cut it out and reseal with a glazing silicone suited to the joint. Common call-outs are for conservatory leaks at frame and glazing joints and failed joints on frameless glass, on glass-to-glass joints, rooflights and glass balustrade bases.
In a village or hamlet like Compton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?
A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we’ll tell you. In a small place like Compton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Compton: your questions answered
Is Compton in your area for glazing silicone?
Yes. We work across London and the South East, and Compton is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
What guarantee comes with glazing silicone in Compton?
All our work, in Compton and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Why not top up the existing silicone?
It doesn’t last. Fresh silicone will not bond to cured silicone, so we remove the old sealant and clean the joint.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Compton.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Avoid scraping close to the bead
- Clean glass with a mild cleaner and a soft cloth
- Clear the conservatory gutters regularly
- Do not leave a drip for the next storm
Check the joints once a year. Spotting a crack early means a simpler fix.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
What we’re called out for in Compton
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
The problems people normally mention when they call include:
- Water escaping where a screen meets the wall
- Water running down inside the glass
- New silicone smeared over old sealant
- Cracked silicone between glass panels
Schools such as Compton C.E. Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. Somewhere like Compton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Advice
What glazing silicone looks like in Compton
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.
In the older streets around Church of St Mary and St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

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 doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
