How we handle glazing silicone in Sunningdale
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. If you are dealing with cracked silicone between glass panels and black or yellowed silicone on glass joints, we can put it right.
Around Sunningdale, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
All of our work is guaranteed for twelve months, in Sunningdale and everywhere else we cover.

For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
When it is not the sealant
Before you book, it’s worth knowing the limits:
- A frame that needs repairing or replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
- Cracked or broken glass
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal
- Conservatory frames
- Glass-to-glass joints
- Glass-to-frame joints
- Glass balustrade bases
- Rooflights
- Shower screens
Why it’s worth doing now in Sunningdale
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. Homes in smaller places like Sunningdale can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long does glazing silicone take?
That depends on the amount of work, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We will tell you when we quote.

Yes. Mr Mastic is an ARBOMaster approved applicator.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What glazing silicone looks like in Sunningdale
Historic houses like St Leonard's Hill (about 4.8 miles north) are a reminder that the area around Sunningdale has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For an older house near a landmark such as Holy Trinity Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Holy Trinity CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What else we do in Sunningdale
How we quote for glazing silicone
There’s no set price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- Access and height
- The product the joint needs
- Mould in or behind the old joints
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
When you contact us, it’s useful to know:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved.
Do you need glazing silicone in Sunningdale?
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
People usually contact us after spotting one of these:
- Failed sealant around rooflight glass
- Mouldy sealant around glass panels
- Conservatory leaks at frame and glazing joints
- Silicone pulling away from the glass
Rented homes near Sunningdale station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from an hour or two to most of a day, depending on the size of the job. A visit to Sunningdale is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- We clean the joint with a solvent that suits the glass and frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any tricky access
- Move anything stored near the joints
