How we handle glazing silicone in Headcorn
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. Common call-outs are for black or yellowed silicone on glass joints and cracked silicone between glass panels, on conservatory frames, glass balustrade bases and glass-to-frame joints.
Homes around Headcorn range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Whatever the size of the job, you get the same 12-month guarantee in Headcorn and across Kent.

Questions from Headcorn
Can you help a landlord with a rental near Headcorn station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is Headcorn within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you replace a misted double-glazed unit?
That is not something we do. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.
How long does the job take?
A typical job takes a few hours for most jobs, including the preparation. We will confirm how long when we quote.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Is a special sealant needed for glass?
Glass needs a sealant made for glazing. Ours is a neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Headcorn homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Headcorn station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as Headcorn Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Common problems we fix in Headcorn
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.
If you can see any of these, it’s time to have the joints looked at:
- A quick top-up bead that didn’t last
- Rooflight joints letting water in
- Shower screens leaking along the wall or tray
- Split or lifting silicone on glass
Homes close to St Peter's and St Paul's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
- What insurance they hold
- How the surfaces are prepared before sealing
Why act early in Headcorn
Fixing a leaking screen early protects what’s underneath. A small leak can reach the floor below before you notice. In an older home around Headcorn, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Mouldy or split sealant often shows up at the end of a tenancy. 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. Keeping joints in good order is simple maintenance.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on how many joints need doing in most cases. For a job in Headcorn, 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.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
