Capstone homes and the weather
Capstone is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on glazing joints and frame seals, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Gillingham (Kent) 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 All Saints Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

About our glazing silicone in Capstone
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. If you’re dealing with rooflight joints letting water in and water tracking down the inner face of the glass, we can help, on conservatory frames, shower screens and glass balustrade bases alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Capstone is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Common problems we fix in Capstone
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
Look out for these signs:
- New silicone smeared over old sealant
- Rooflight joints letting water in
- Failed joints on frameless glass
- Stained, discoloured glazing silicone
Schools such as Hempstead Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- When the joint can take water or movement
- Which sealant they’ll use, and why

FAQs for Capstone
Does living near the coast affect glazing silicone in Capstone?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like Capstone?
Yes. Capstone is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How much does glazing silicone cost in Capstone?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Can you just put new silicone over the old?
A top-up rarely holds. The new bead cannot grip the old one so we take it all out and start clean.
Do you work for letting agents?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep conservatory gutters clear of leaves
- Avoid strong solvents on or near the sealant
- Squeegee the shower screen after each use
- Stick to mild cleaners on glass
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.
How the job changes by surface
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
Glass balustrade bases
The base joint is cut out and resealed. We don’t install or replace glass.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Glass that needs replacing
- Structural problems with a conservatory roof
- Condensation trapped between two panes
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

How it works
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many joints need doing. Somewhere as small as Capstone, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We look over every joint and, where we can, test it with water.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
