Glazing silicone in Thatcham, done properly
Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. Common call-outs are for drips on the inside of a conservatory window and failed joints on frameless glass, across glass-to-frame joints, glass balustrade bases and rooflights.
Around Thatcham, many houses have gained conservatories, French doors or replacement windows over time. Every addition brings more joints, each wearing at its own pace. Sills, frame heads and glazing joints are where leaks normally start.
Our work is backed for twelve months.

Different surfaces, different methods
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Rooflights
Water around a rooflight is not always the sealant. We find the cause first.
When to call us in Thatcham
Sealant laid over old sealant does not last. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Any of these means the joints need attention:
- Rooflight joints letting water in
- Water escaping where a screen meets the wall
- Failed joints on frameless glass
- Water running down inside the glass
If you look after a building such as Spurcroft Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What affects the cost of glazing silicone
The quote reflects the job in front of us. We take into account:
- Access and height
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The product the joint needs
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- If someone has resealed it before
- How many joints, rooms or windows are involved
- Where the job is, and your postcode
For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
Thatcham questions
Is Thatcham in your area for glazing silicone?
Yes, Thatcham is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
What guarantee comes with glazing silicone in Thatcham?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you fit new glass or sealed units?
We do not replace glass. We look after the sealant joints and can tell you if a unit seems to have gone.
Can a conservatory leak be sealed?
That depends where the water is getting in. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Can you reseal the base of a glass balustrade?
We can, if the base joint is sealed. Photos help us see what’s there when you ring 0345 464 0079 or email us.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is a special sealant needed for glass?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.

Why it’s worth doing now in Thatcham
If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly, so you can call the right trade. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
What you get with us

How the visit works
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Thatcham, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First, we trace the leak and check it’s coming through a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
How to get a quote
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and give you a clear price.
Advice
Looking after it afterwards
Aftercare is simple:
- Act on drips or damp patches early
- Keep harsh solvents off the silicone
- Squeegee the shower screen after each use
- Use a gentle glass cleaner and a soft cloth
Do not use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
Thatcham homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Shaw House (about 2.7 miles west) nearby, there’s older building stock in the area around Thatcham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Thatcham station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around United Reformed Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

When it is not the sealant

- Water coming through the roof rather than a sealant joint
- A sealed unit that has misted inside
- Structural problems with a conservatory roof
