About our glazing silicone in Longfield
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. If you are dealing with water getting into a conservatory at the joints and glass-to-glass joints that have split, we can put it right, on rooflights, conservatory frames and glass-to-frame joints alike.
In a village or hamlet like Longfield, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months.

How we quote for glazing silicone
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- How easy the joints are to reach
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
What the job involves on each surface
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Glass balustrade bases
The base of a glass balustrade is normally sealed. Failed sealant there lets water collect.
Questions from Longfield
Do you cover Longfield for glazing silicone?
Yes. We work across London and the South East, and Longfield is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
I let a flat near Longfield station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you seal glass balustrade bases?
Yes, where the base is finished with sealant. Photos help us see what’s there when you ring 0345 464 0079 or email us.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
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.
Which silicone is used for glass joints?
A glazing-grade silicone is best. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Where are you based?
We are based in Crawley, and we work across South East England, London and Scotland.
Landlords, agents and businesses in Longfield

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Do you need glazing silicone in Longfield?
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip on the glass.
People normally contact us when they notice one of these:
- Conservatory leaks at frame and glazing joints
- Rooflight joints letting water in
- Drips on the inside of a conservatory window
- Water escaping where a screen meets the wall
For site and facilities teams at buildings such as Longfield Academy, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- What the cure time is
- How hidden problems are handled
- Are they insured?
- What product goes in the joint

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Inspect the sealant on glazing annually
- Wipe the screen down after showering
- Clear the conservatory gutters regularly
- Keep scrapers and blades away from the silicone
Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
What glazing silicone looks like in Longfield
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Cobham College (about 4 miles east) are a reminder that the area around Longfield has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of Saint Mary Magdalene, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Longfield station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.
