Frames and glazing around Cross in Hand
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.
For site and facilities teams at buildings such as Cross-in-Hand Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Bartholomew, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Buxted station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

How we handle glazing silicone in Cross in Hand

Mastic can only go onto a dry, clean joint, so window work in Cross in Hand is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Cross in Hand 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.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
How to prepare
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children

Aftercare tips
After the cure time, these simple habits help:
- Clear the conservatory gutters regularly

- Avoid scraping close to the bead
- Use a gentle glass cleaner and a soft cloth
Follow the cure time we give you before the joints get wet. From then on, a mild glass cleaner is all it needs.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.

It helps to know what we can’t do:

- Water coming through the roof rather than a sealant joint

Why it’s worth doing now in Cross in Hand
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before it shows. In a small place like Cross in Hand, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
What you get with us
- Tidy, careful work
- Approved under the ARBOMaster scheme
- Anti-fungal sanitary silicone in wet areas
- Any old sealant cut out fully, not covered over
Quotes for glazing silicone in Cross in Hand
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Whether the work is at height
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:

- Photos by email, if that is easy
- The address or postcode of the job
We quote each job on its own. Simply call 0345 464 0079 or send us an email and describe the job.
Common questions in Cross in Hand
Is Cross in Hand within the area you cover?
Yes, Cross in Hand is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Buxted station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you fit new glass or sealed units?
Glass replacement isn’t our trade. We look after the sealant joints and can tell you if a unit seems to have gone.
Can you fix a leaking conservatory?
If the water is coming in through failed sealant joints, yes. If the cause is the roof, a panel or a unit, we’ll say so.
Can you reseal a frameless shower screen?
Yes, we do these often. We use anti-fungal silicone suited to bathrooms.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
