Glazing silicone in Thundridge
We don’t replace glass and a misted double-glazed unit needs a glazier. Our work is the sealant joints, which is where many leaks start. If you’re dealing with water escaping where a screen meets the wall and glazing silicone that has cracked or come away, we can help, whatever the surface.
Somewhere as small as Thundridge, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

Advice
Thundridge homes and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Much Hadham Palace (about 4.8 miles east) are a reminder that the area around Thundridge 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’s traditional sand mastic.
Schools such as Thundridge Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Parish Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Thundridge is about 1 mile north of Ware, in Hertfordshire. From the centre of Thundridge to the outskirts, glazing silicone is available for homes and businesses alike.

What happens if it’s left?
Replacing a conservatory roof is major work. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we will tell you. Older cottages and farmhouses around Thundridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
Why us?
- Old sealant always removed completely

Common questions in Thundridge
Is Thundridge in your area for glazing silicone?

Can you help a landlord with a rental near Ware station?

Will resealing stop my conservatory leaking?
If the water is coming in through failed sealant joints, yes. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Do you seal glass balustrade bases?
We can. We cut out the failed sealant and reseal the base joint with a suitable product.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on how many joints need doing. We’ll give you a better idea when we quote.
What should I tell you?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Thundridge, along with the rest of our area.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How the job changes by surface
Shower screens
Black or peeling silicone on a screen lets water out. Cutting it out and resealing fixes it.
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Signs you need glazing silicone in Thundridge
The wrong sealant is a common cause. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
The most common problems we see are:
- Black or yellowed silicone on glass joints
- Split or lifting silicone on glass
- New silicone smeared over old sealant
- Water getting into a conservatory at the joints
Rented homes near Ware station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
