About our glazing silicone in Crofton
Glass, frames and walls all move at different rates, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. We work on glass-to-glass joints, shower screens and glass-to-frame joints, and the jobs we see most are rooflight joints letting water in and split or lifting silicone on glass.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What affects the cost of glazing silicone
For a quick quote, just ask. What matters most is:
- How much there is to do
- The type of sealant required
- How many rooms, windows or areas are involved
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
When you contact us, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- Roughly how big the job is
- The address or postcode of the job
To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
What happens on the day
The work is kept neat and contained to the area we are working on. The job normally takes anything from an hour or two to most of a day, depending on the size of the job. In Crofton, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

Frames and glazing around Crofton
Historic houses like Bromley Palace (about 3.2 miles north-west) are a reminder that the area around Crofton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
If you let a flat or house near Orpington station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you live in an older home near Church of Jesus Christ of Latter-Day Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Crofton is about 1 mile south-west of Orpington, in Greater London. Every kind of property in Crofton is covered for glazing silicone, old or new, large or small. Every job comes with our one-year guarantee. Crofton is one of 764 places in Greater London we cover. You can also see our page for London, roughly 11 miles from Crofton.

Is parking an issue for glazing silicone in Crofton?
Parking in Crofton, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Crofton.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Looking after it afterwards
To keep the joints looking good and working properly:
- Clear the conservatory gutters regularly
- Use gentle products around the joints
- Don’t use a blade near the sealant
- Get a new leak looked at quickly
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.
What happens if it’s left?
Replacing a conservatory roof is major work. 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. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Crofton, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.

Landlords, agents and businesses in Crofton
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.

- Structural problems with a conservatory roof
- Rotten or badly damaged frames
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Glass-to-frame joints
- Rooflights
- Conservatory frames
- Shower screens
- Glass balustrade bases

What else we do in Crofton
Common problems we fix in Crofton
New silicone over old silicone won’t bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Most people get in touch when they notice something like this:
- Water getting into a conservatory at the joints
- A quick top-up bead that didn’t last
- Split or lifting silicone on glass
- Water escaping where a screen meets the wall
Crofton is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
