West Wittering Glazing Silicone
Glazing joints in West Wittering need attention? We cut out the old, prepare the joints and apply the right sealant.
- Conservatory leaks at frame and glazing joints
- Stained, discoloured glazing silicone
- Leaking glazing joints on a rooflight
What the job involves on each surface
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. A failed bead lets water in.
Glass balustrade bases
The base joint is cut out and resealed. Glass fitting is a separate trade.
Glazing silicone in West Wittering
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it, and if it’s something sealant can’t fix, we will tell you. We work on shower screens, glass balustrade bases and conservatory frames, and the jobs we see most are leaks where conservatory glass meets the frame and leaks from the base of a shower screen.
Mastic can only go onto a dry, clean joint, so window work in West Wittering is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

Signs you need glazing silicone in West Wittering
Heat and cold make glass and frames move, and they do not move by the same amount. Over years, that movement tears the silicone.
The most common problems we see are:
- Leaking glazing joints on a rooflight
- Stained, discoloured glazing silicone
- Water running down inside the glass
- Silicone pulling away from the glass
In the older streets around The Parish Church of St Peter and St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in.

Glazing silicone in West Wittering: local notes
West Wittering is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Nutbourne station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you look after a building such as West Wittering Parochial Church of England School, larger buildings have plenty of frames, and the mastic around each one ages.

What else we do in West Wittering
West Wittering questions
Does the coastal weather in West Wittering 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. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Nutbourne station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover West Wittering.
Do you seal glass balustrade bases?
Yes. The sealant joint at the base can be renewed. We don’t install or replace the glass.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Which silicone is used for glass joints?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Can I do it myself?
If you’re set on DIY, put the effort into 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.
Some sealant jobs are within reach of a careful DIYer, 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.
Landlords, agents and businesses in West Wittering
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Why deal with it now?
If the problem is a misted unit or a broken panel, sealant will not help. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. Around West Wittering, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the gutters above the glazing for debris
- Get a new leak looked at quickly
- Keep scrapers and blades away from the silicone
- Inspect the sealant on glazing annually
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most jobs. Somewhere as small as West Wittering, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
