Glazing & conservatory sealant in Chilbolton, Hampshire
We cover Chilbolton for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old material cut out, joints cleaned and sealed neatly.
- Failed sealant around rooflight glass
- Water escaping where a screen meets the wall
- Split or lifting silicone on glass
Why deal with it now?
A quick bead over the old sealant might stop a drip for a while, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. In a small place like Chilbolton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why book with us
- White, clear, grey or another colour, product permitting
- Sealant colour chosen to suit
- A 12-month guarantee on all work
- ARBOMaster approved applicator

Glazing silicone in Chilbolton
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for sealant that was laid over old silicone and failed and stained, discoloured glazing silicone, across glass-to-glass joints, rooflights and glass balustrade bases.
Mastic can only go onto a dry, clean joint, so window work in Chilbolton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, it’s backed by our 12-month guarantee in Chilbolton and across Hampshire.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Where do you work from?

Will resealing stop my conservatory leaking?
Often, if the leak is at a sealant joint. We trace the leak first before any sealing.
How long will you be here?
Most jobs take a few hours, depending on how many joints need doing, including preparation and clearing up. We will confirm how long when we quote.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.

What glazing silicone looks like in Chilbolton
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Wherwell Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Mary the Less, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What affects the cost of glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- Which sealant suits the joint
- Working hours on commercial sites
- Any mould that needs treating
Doing several joints on one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

What we are called out for in Chilbolton
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Signs it’s time to call us include:
- Split or lifting silicone on glass
- Stained, discoloured glazing silicone
- Water tracking down the inner face of the glass
- Cracked silicone between glass panels
Rented homes near Andover station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Questions to ask before you book
- Which colour the sealant will be
- What guarantee comes with the work
- Who turns up on the day
- Is VAT in the price?
How it works
The work is kept neat and contained to the joints we’re treating. The job generally takes anything from an hour or two to most of a day, depending on the size of the job, and we explain the cure time before we leave. Somewhere as small as Chilbolton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
