DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, 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.
How we handle glazing silicone in Cross Gate
We do not replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that is often where the water gets in. Typical jobs include sealant that was laid over old silicone and failed and water tracking down the inner face of the glass, on conservatory frames, rooflights and shower screens.
Outdoor sealant needs dry, clean surfaces, so work on frames around Cross Gate is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

- Leaks where conservatory glass meets the frame
- Water running down inside the glass
- Leaks from the base of a shower screen

Common questions in Cross Gate
I let a flat near Amberley station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Cross Gate?
Yes, Cross Gate is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does the job take?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can you just put new silicone over the old?
Silicone doesn’t stick to silicone and water gets between the layers. The old bead always comes out first.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Cross Gate and the rest of West Sussex.
Do you reseal glass shower screens?
Yes, we do these often. The screen is resealed with anti-fungal silicone made for wet areas.
What happens if it’s left?
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes, and we’ll tell you if that’s not the case. In a small place like Cross Gate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Frames and glazing around Cross Gate
With historic houses such as Parham House (about 1.1 miles east) nearby, there’s older building stock in the area around Cross Gate 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Amberley CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around The Parish Church of St Michael and All Angels, the joint between an old wall and a newer frame is usually the first place rain gets in.

Looking after it afterwards
So the new joints stay in good condition:
- Act on drips or damp patches early
- Check the silicone on glass every year or so
- Run a squeegee over the glass when you’re done
- Keep scrapers and blades away from the silicone
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most jobs in most cases. Somewhere like Cross Gate needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
