Glazing silicone in West Marden
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We’re often asked to deal with glass-to-glass joints that have split and new silicone smeared over old sealant, on glass-to-glass joints, conservatory frames and rooflights.
Outdoor sealant needs dry, clean surfaces, so work on frames around West Marden is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, whatever its size.

How we quote for glazing silicone
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- The old material and how stubborn it is
- The product the joint needs
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. Just tell us:
- Whether it has been sealed before
- The problem you’ve noticed
- A few pictures by email, if you can
- The type of property
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
Common problems we fix in West Marden
Shower screen silicone gets wet every day. Mould grows into the bead and the edges begin to peel.
People usually contact us when they notice something like this:
- Cracked silicone between glass panels
- Water tracking down the inner face of the glass
- Leaking glazing joints on a rooflight
- Stained, discoloured glazing silicone
If you live in an older home near The Parish Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Who does the work, and how experienced they are
- Is VAT in the price?
- How the surfaces are prepared before sealing
- How long to leave it before use

Will you come out to West Marden?

How long will you be here?

Are you fully insured?

Is the work guaranteed?
There’s a 12-month guarantee on every job, glazing sealant included.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it enough to run a bead over the old sealant?
New silicone will not bond to old silicone and water gets between the layers. The old bead always comes out first.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Glazing silicone in West Marden: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Uppark (about 2.6 miles north) are a reminder that the area around West Marden has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Rowlands Castle station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as Compton and Up Marden CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How to look after the new joints
So the new joints stay in good condition:
- Keep conservatory gutters clear of leaves
- Ventilate the conservatory to cut condensation
- Get a new leak looked at quickly
- Use gentle products around the joints
Keep the new joints dry for as long as we advise. From then on, a mild glass cleaner is all it needs.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for most jobs, depending on the amount of work. In a small place like West Marden, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- The joints are checked before we leave.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Tell us about any water getting in

Different surfaces, different methods
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We renew it with a clear or matching glazing silicone.
Shower screens
Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Condensation trapped between two panes
- Water coming through the roof rather than a sealant joint
- A sagging or failing conservatory roof
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
