About our glazing silicone in Langstone
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. We work on glass-to-glass joints, rooflights and shower screens, and people most often call us about water running down inside the glass and black or yellowed silicone on glass joints.
Mastic can only go onto a dry, clean joint, so window work in Langstone is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same one-year guarantee in Langstone and across Hampshire.

Questions from Langstone
Does the coastal weather in Langstone affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you cover smaller places like Langstone?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee do I get?
You get our one-year guarantee to every job we do.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
How much does glazing silicone cost in Langstone?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
What glazing silicone looks like in Langstone
Langstone is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. 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.
For landlords with property near Havant station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. For site and facilities teams at buildings such as Bosmere Junior School, larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for most jobs. For a village or hamlet like Langstone, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip 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.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Let us know about earlier repairs to the joints
Ask for a quote

What affects the cost of glazing silicone
Call for a quick quote. The main things that affect it are:
- Any mould that needs treating
- The number of rooms or windows
- How easy the joints are to reach
- The number and length of the joints
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What we need to know
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- A broken pane or roof panel
- A sagging or failing conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Where we work in Langstone

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
What happens if it’s left?
A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. Where a wall is exposed, as many are in small places like Langstone, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Common problems we fix in Langstone
UV light ages silicone, especially on conservatory roofs. It goes brittle, cracks and stops sticking to the glass and frame.
People normally contact us when they notice something like this:
- Shower screens leaking along the wall or tray
- Mouldy sealant around glass panels
- Silicone pulling away from the glass
- Cracked silicone between glass panels
If you live in an older home near Saint Nicholas' Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
