Glazing silicone for homes and businesses in Greenhill
Glass replacement isn’t something we do and a misted double-glazed unit needs a glazier. Our work is the sealant joints and that is often where the water gets in. If you have sealant that was laid over old silicone and failed and water tracking down the inner face of the glass, we can put it right, whatever the surface.
In a smaller place like Greenhill, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Glazing silicone in Greenhill: local notes
Greenhill 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. 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.
Letting a property close to Herne Bay station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as Thornden Wood Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Greenhill is about 1 mile south-west of Herne Bay, in Kent. For glazing silicone in and around Greenhill, it’s easy to get a quote: please call 0345 464 0079 or drop us an email.

What affects the cost of glazing silicone
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- The number and length of the joints
- Whether there’s mould to deal with
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
To help us quote quickly, let us know:
- What’s wrong with the joints now
- Roughly how big the job is
- Access, such as stairs, a lift or height
- The type of property

Greenhill: your questions answered
I let a flat near Herne Bay station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Will you come out to Greenhill?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you reseal a frameless shower screen?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
Are you insured?
Yes. We are fully insured.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you replace glass?
No. We renew the sealant. Glass and sealed units need a glazier.
Is the work guaranteed?
Our 12-month guarantee applies to every job we do.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Why act early in Greenhill
A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we will tell you. In an older home around Greenhill, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
What happens on the day
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing for a typical job. Parking around Greenhill is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we check where the water gets in.
- 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.
How to prepare
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details and send pictures if you have them.
Advice
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Run a squeegee over the glass when you are done
- Don’t leave a drip for the next storm
- Keep scrapers and blades away from the silicone
- Use gentle products around the joints
Follow the cure time we give you before the joints get wet. After that, clean glass with a mild cleaner.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.
When to call us in Greenhill
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
These are the problems we are asked about most:
- Sealant that was laid over old silicone and failed
- Water running down inside the glass
- Cracked silicone between glass panels
- Failed sealant around rooflight glass
If you live in an older home near St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
