Glazing silicone in Welborne
Glazing silicone that has yellowed, blackened or come away spoils the look and lets water in. It comes off cleanly, without marking the glass and reseal the joint. If you have glass-to-glass joints that have split and glazing silicone that has cracked or come away, we can put it right, whatever the surface.
Homes in small places like Welborne often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Frames and glazing around Welborne
Welborne 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.
If you let a flat or house near Fareham station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. In the older streets around Church of St Francis, the joint between an old wall and a newer frame is normally the first place rain gets in.

The job generally takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. Somewhere like Welborne needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Try not to wet indoor joints just before the visit

What else we do in Welborne
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
When something else is needed
A few problems are outside what sealant work can do:
- Cracked or broken glass
- Water coming through the roof rather than a sealant joint
- A sagging or failing conservatory roof
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Where we work in Welborne
- Glass-to-glass joints
- Rooflights

What affects the cost of glazing silicone
You’ll get a clear quote before we start. It’s based on:
- Whether there’s mould to deal with
- When we can work, for business premises
- How many rooms, windows or areas are involved
- The amount of work
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What to tell us for a quote
When you call or email, it’s useful to know:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Where the property is
- If someone has resealed it before
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
Common questions in Welborne
I let a flat near Fareham station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Does the coastal weather in Welborne affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
How much does glazing silicone cost in Welborne?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Can you just put new silicone over the old?
It doesn’t last. Fresh silicone will not bond to cured silicone so we take it all out and start clean.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you need glazing silicone in Welborne?
Using a sealant not made for glass causes many failures. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
Signs it’s time to call us include:
- Failed joints on frameless glass
- Split or lifting silicone on glass
- Stained, discoloured glazing silicone
- Leaking glazing joints on a rooflight
For site and facilities teams at buildings such as The Henry Cort Community College, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Who turns up on the day
- Are they insured?
- What happens if the job turns out different
- Whether VAT is included
Why it’s worth doing now in Welborne
Topping up old silicone can look like a fix, but new silicone will not bond to old, and the leak usually returns. A proper reseal is the lasting answer. Where a wall is exposed, as many are in small places like Welborne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
