Glazing silicone in Markbeech
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points and both get fresh anti-fungal silicone. Typical jobs include stained, discoloured glazing silicone and sealant that was laid over old silicone and failed, on glass-to-glass joints, conservatory frames and shower screens.
In a village or hamlet like Markbeech, 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.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Your questions about glazing silicone in Markbeech
Do you work for landlords with property near Cowden station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Markbeech?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is balustrade sealant something you do?
We can. The old sealant is removed and the joint resealed using a sealant that suits the materials.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Is it possible to redo the silicone on a shower screen?
Yes. The old bead comes off without marking the glass before cleaning and resealing.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A roof that has moved or dropped
- Cracked or broken glass
- Frames that have decayed or split

Glazing silicone in Markbeech: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hever Castle (about 1.3 miles north) nearby, there’s older building stock in the area around Markbeech as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Cowden station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as Hever Church of England Voluntary Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of the Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Shower screens
Frameless screens rely on silicone at the base and wall. We reseal without scratching the glass.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Open vents or windows to let moisture out
- Check the silicone on glass every year or so
- Use a gentle glass cleaner and a soft cloth
- Avoid strong solvents on or near the sealant
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job. For a village or hamlet like Markbeech, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or email us with the details and send photos if you have them.
Advice
Why it’s worth doing now in Markbeech
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. Around Markbeech, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
