Firle: your questions answered
Do you work for landlords with property near Glynde station?

Is Firle in your area for glazing silicone?
Yes, Firle is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Is it enough to run a bead over the old sealant?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
Glazing silicone for homes and businesses in Firle
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We find the joint that is letting water in and renew it and tell you plainly if the cause is something else. We are often asked to deal with split or lifting silicone on glass and stained, discoloured glazing silicone, on glass balustrade bases, conservatory frames and glass-to-frame joints.
Homes in small places like Firle often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All our work comes with our one-year guarantee, wherever you are in East Sussex.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Wipe the screen down after showering
- Act on drips or damp patches early
- Avoid scraping close to the bead
- Keep conservatory gutters clear of leaves
Gentle products are best near the sealant. Strong solvents can soften or mark it.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Why it’s worth doing now in Firle
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Older cottages and farmhouses around Firle can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why book with us

- White, clear, grey or coloured to suit, where the product allows

Firle homes and the weather
With historic houses such as Firle Place (about 0.4 miles south-east) nearby, there’s older building stock in the area around Firle as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Firle Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Glynde station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

When it is not the sealant

- A sagging or failing conservatory roof
- A sealed unit that has misted inside
- Leaks from the roof covering or flashing (a roofer’s job)
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.

Signs you need glazing silicone in Firle
The wrong sealant is a common cause. Some products don’t bond well to glass, and acetoxy types can attack some frame materials.
Look out for any of the following:
- Mouldy sealant around glass panels
- Glazing silicone that has cracked or come away
- Sealant that was laid over old silicone and failed
- Failed sealant around rooflight glass
Homes close to The Parish Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How it works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most jobs, depending on how much there is to do. In a small place like Firle, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Clear the area around the work
