Glazing & conservatory sealant in Southampton
Glazing joints in Southampton need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Water escaping where a screen meets the wall
- Mouldy sealant around glass panels
- Water tracking down the inner face of the glass
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes anything from an hour or two to most of a day, depending on the size of the job. Commercial jobs in Southampton can be planned out of hours where a building can’t close, and homes are booked within our usual hours, Monday to Saturday.
- We start by finding the leak and making sure sealant is the cause.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

How we handle glazing silicone in Southampton
Cracked, stained or lifting silicone on glass spoils the look and lets water in. It comes off cleanly, without marking the glass before the new bead goes in. If you have water getting into a conservatory at the joints and drips on the inside of a conservatory window, we can help, whatever the surface.
Plenty of homes in Southampton are rented, and windows are easy to overlook between tenancies. Gaps around a frame let in draughts and water, and tenants notice.
There’s a 12-month guarantee on every job, whatever its size.

Signs you need glazing silicone in Southampton
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
The most common problems we see are:
- A quick top-up bead that didn’t last
- Glass-to-glass joints that have split
- Leaking glazing joints on a rooflight
- Water running down inside the glass
Rented homes near St Denys station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Questions to ask before you book
- How long to leave it before use
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- Whether VAT is included
Southampton: your questions answered
Is Southampton in your area for glazing silicone?
Yes. Our work covers London and the South East, and Southampton is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Does living near the coast affect glazing silicone in Southampton?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
What guarantee do I get?
There’s a 12-month guarantee on every job.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Is balustrade sealant something you do?
Yes. The sealant joint at the base can be renewed. We don’t install or replace the glass.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Why deal with it now?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. For landlords in Southampton, failed sealant soon turns into tenant complaints about mould, damp or draughts. Sorting it between tenancies is easier than dealing with it mid-let.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
- Tidy, careful work
- Any old sealant cut out fully, not covered over

Frames and glazing around Southampton
Southampton 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. Historic houses like Southampton Tudor House and Garden (about 1.4 miles south) are a reminder that the area around Southampton 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 is traditional sand mastic.
If you look after a building such as Bevois Town Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Saint Mary's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

We work across the SO19, SO16, SO15 and SO18 postcode area for glazing silicone. Glazing silicone is available to properties on London Road, Marshall Square and Grosvenor Square. You will find Southampton on the A27 and A33, which makes it straightforward to reach with everything needed for glazing silicone. Neighbouring places we cover for glazing silicone include Inner Avenue (1 mile west), St Denys (1 mile north-east), Bitterne Manor (1 mile east), Portswood (1 mile north) and Northam (1 mile south-east).

Local landmarks in Southampton
We work in homes and buildings around Rockstone Place Park, The Hobbit pub and St Mary's Independent School. Southampton has its own railway station: St Denys station. Other landmarks nearby include Marlands Shopping Centre (1 mile south-west) and R J Mitchell Museum (0.9 miles south-west). The countryside around Southampton includes Netley Common.
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 chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Squeegee the shower screen after each use
- Avoid strong solvents on or near the sealant
- Act on drips or damp patches early
- Keep conservatory gutters clear of leaves
On shower screens, wipe or squeegee after use and keep the room ventilated. It helps stop mould getting into the silicone.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below before you spot it.
