Glazing silicone for homes and businesses in Westwood
We work across Westwood on glazing joints for homes and businesses. Conservatories, rooflights, glass panels and shower screens are all part of the job. If you’re dealing with sealant that was laid over old silicone and failed and shower screens leaking along the wall or tray, we can put it right, on shower screens, conservatory frames and glass-to-glass joints alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Westwood is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Leave it or put it right?
Resealing can’t fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway, so you can call the right trade. Older cottages and farmhouses around Westwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Glazing silicone in Westwood: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Cobham College (about 4.6 miles east) are a reminder that the area around Westwood 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.
If you live in an older home near Church of Saint Mary Magdalene, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Bean Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Westwood
Can you help a landlord with a rental near Longfield station?
Yes. We work for letting agents and landlords as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover smaller places like Westwood?
Yes. Westwood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Which silicone is used for glass joints?
A glazing silicone chosen for the joint. Neutral-cure products suit most glass and frames, as some acetoxy types can attack certain metals.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for most jobs from start to finish. For a village or hamlet like Westwood, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We trace the leak and confirm it’s a sealant joint.
- 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.
Before we arrive
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

Related advice
What affects the cost of glazing silicone
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The number of rooms or windows
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- The number and length of the joints
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
To help us quote quickly, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll send you a clear quote before any work starts.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
We also work for property managers and facilities teams in Westwood and across Kent. We can quote a run of properties together.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Run a squeegee over the glass when you’re done
- Avoid scraping close to the bead
- Open vents or windows to let moisture out
- Don’t leave a drip for the next storm
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.
Signs you need glazing silicone in Westwood
Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
These are the problems we are asked about most:
- A quick top-up bead that didn’t last
- Split or lifting silicone on glass
- Rooflight joints letting water in
- Water running down inside the glass
For landlords with property near Longfield station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
