About our glazing silicone in Heathfield
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on shower screens, glass-to-glass joints and glass-to-frame joints, and the jobs we see most are new silicone smeared over old sealant and water tracking down the inner face of the glass.
In a smaller place like Heathfield, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Each job carries a 12-month guarantee, large or small.

Heathfield: your questions answered
Is Heathfield within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is there a guarantee on glazing silicone in Heathfield?
All our work, in Heathfield and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours, depending on how many joints need doing. We’ll give you a better idea when we quote.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.

For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
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 we’re called out for in Heathfield
Glass and frames expand and contract with the temperature, and they don’t move by the same amount. In time, the sealant splits or pulls away.
Most people get in touch when they notice something like this:
- Leaking glazing joints on a rooflight
- Leaks where conservatory glass meets the frame
- Water running down inside the glass
- Silicone pulling away from the glass
If you look after a building such as Parkside Community Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Glass-to-glass joints
These joints are on show, so we take care to leave a neat bead.
Windows and doors in Heathfield
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.
Homes close to St Richards Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on how many joints need doing in most cases. A visit to Heathfield is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Why act early in Heathfield
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Homes in smaller places like Heathfield 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 the work is at height. We take all of that into account in your quote.
