Glazing silicone in Overton, done properly
We don’t replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. We work on conservatory frames, shower screens and glass-to-glass joints, and the jobs we see most are drips on the inside of a conservatory window and leaks from the base of a shower screen.
Houses in smaller places like Overton can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
Whatever the size of the job, you get the same one-year guarantee in Overton and across Hampshire.

How the visit works
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for most jobs, depending on the size of the job. For a job in Overton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- Tell us if parking is tricky

What affects the cost of glazing silicone
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- When we can work, for business premises
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Whether it has been sealed before
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
What happens if it’s left?
If the problem is a misted unit or a broken panel, sealant won’t help. We will tell you that rather than seal it anyway and point you to a glazier or roofer. Homes in smaller places like Overton can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
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 we need extra access for height. Your quote takes all of that into account.

- A choice of colours where the product allows

Overton questions
Will you come out to Overton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Overton for glazing silicone?
Yes, Overton is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Is the work guaranteed?
Every job comes with our 12-month guarantee.
Which silicone is used for glass joints?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone with anti-fungal products in bathrooms.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Inspect the sealant on glazing annually
- Wipe the screen down after showering
- Avoid strong solvents on or near the sealant
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Water coming through the roof rather than a sealant joint
- A roof that has moved or dropped
- A sealed unit that has misted inside
If in doubt, call 0345 464 0079 or email us and we will say what we think.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Glazing silicone in Overton: 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.
Letting a property close to Overton station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Overton Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
