Glazing silicone for homes and businesses in Foots Cray
Sealant on glazing does not last for ever. Weather and movement take their toll, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. If you’re dealing with failed sealant around rooflight glass and conservatory leaks at frame and glazing joints, we can help, whatever the surface.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Foots Cray.
Each job carries a 12-month guarantee, large or small.

When to call us in Foots Cray
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
These are the problems we are asked about most:
- Shower screens leaking along the wall or tray
- Glazing silicone that has cracked or come away
- Water tracking down the inner face of the glass
- Rooflight joints letting water in
If you live in an older home near Parish Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Inspect the sealant on glazing annually
- Ventilate the conservatory to cut condensation
- Get a new leak looked at quickly
- Don’t use a blade near the sealant
Gentle products are best near the sealant. Harsh solvents may damage the bead.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we’ll find out which.

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
The process
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job in most cases. In Foots Cray, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- The joints are checked before we leave.
How to prepare
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Why deal with it now?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we will say so. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Questions from Foots Cray
Do you cover Foots Cray for glazing silicone?
Yes, Foots Cray is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
I let a flat near Sidcup station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you replace glass?
That is not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Foots Cray homes and the weather
Historic houses like Danson House (about 2.8 miles north) are a reminder that the area around Foots Cray has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Sidcup station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. Managing a site like Orchard Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
