Glazing silicone for homes and businesses in Tilgate
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. If you are dealing with water escaping where a screen meets the wall and water tracking down the inner face of the glass, we can help, whatever the surface.
Homes around Tilgate 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.
Every job comes with a one-year guarantee, wherever you are in West Sussex.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Your questions about glazing silicone in Tilgate
Is Tilgate 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.
Do older homes in Tilgate need their sealant replacing?
If it hasn’t been replaced for some years, it’s generally worth it. Sealant is a maintenance item: how long it lasts depends on use, cleaning and exposure, and many homes in Tilgate may already be on their second or third set.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What does glazing silicone cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you replace a misted double-glazed unit?
We do not replace glass. We look after the sealant joints and can tell you if a unit seems to have gone.
Can you fix a leaking conservatory?
It depends on the cause. Sealant joints we can renew but roof and panel problems need another trade.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Tilgate.
How long does the job take?
Typically it takes a few hours, depending on how many joints need doing. Larger jobs naturally take longer.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most jobs. For a job in Tilgate, 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 trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints

- For business premises, tell us about site rules or sign-in

Frames and glazing around Tilgate
Historic houses like Tyes Place (about 4.6 miles south) are a reminder that the area around Tilgate has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like The Oaks Primary School & Nursery? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to look after the new joints
So the new joints stay in good condition:
- Clean glass with a mild cleaner and a soft cloth
- Keep conservatory gutters clear of leaves
- Ventilate the conservatory to cut condensation
- Keep scrapers and blades away from the silicone
Avoid scraping near the new silicone when cleaning the glass. A soft cloth or sponge is best.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
What affects the quote in Tilgate
The quote reflects the job in front of us. We look at:
- Access and height
- Any mould that needs treating
- The number of rooms or windows
- Any working-time requirements on site
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Helping us quote
To make quoting easier, let us know:
- Roughly how big the job is
- A few photos by email, if you can
- Whether it has been sealed before
- Where the job is, and your postcode
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When to call us in Tilgate
The wrong sealant is a common cause. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
Most people get in touch after spotting one of these:
- A quick top-up bead that didn’t last
- Stained, discoloured glazing silicone
- Conservatory leaks at frame and glazing joints
- Split or lifting silicone on glass
Rented homes near Crawley station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

- Whether you can choose the colour
- Is the old sealant removed completely?
