Glazing Silicone in Westcroft
We cover Westcroft for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly.
- Glazing silicone that has cracked or come away
- Water running down inside the glass
- New silicone smeared over old sealant
About our glazing silicone in Westcroft
Glass and frames expand and contract differently, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. We work on rooflights, glass-to-glass joints and glass balustrade bases, and common reasons people get in touch are water running down inside the glass and stained, discoloured glazing silicone.
Many houses in smaller places like Westcroft have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most jobs for a typical job. For a job in Westcroft, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work
- Tell us about any water getting in

Questions from Westcroft
I let a flat near Milton Keynes Central station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Westcroft?
Yes. Westcroft is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What sealant do you use on glazing?
A glazing-grade silicone is best. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Is it possible to redo the silicone on a shower screen?
Yes. The old bead comes off without marking the glass before cleaning and resealing.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Work for landlords, hotels and businesses
For anyone letting property in or around Westcroft, several properties can be quoted together. Just tell us the addresses and what each one needs.
Landlords and letting agents in Westcroft can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Look over the glazing joints once a year
- Stick to mild cleaners on glass
- Open vents or windows to let moisture out
- Get a new leak looked at quickly
Squeegee a shower screen after each shower and let the room air. That slows mould growth on the bead.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
Common problems we fix in Westcroft
New silicone over old silicone will not bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
People normally contact us when they notice something like this:
- Water running down inside the glass
- Glazing silicone that has cracked or come away
- Sealant that was laid over old silicone and failed
- Water escaping where a screen meets the wall
For an older house near a landmark such as St Giles's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- What the cure time is
- How the joint is cleaned and prepared
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Rotten or badly damaged frames
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- A roof that has moved or dropped
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Frames and glazing around Westcroft
Historic houses like Bletchley Park (about 2.4 miles east) are a reminder that the area around Westcroft has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Oxley Park Academy, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Milton Keynes Central station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.
