About our glazing silicone in Amersham on the Hill
Not every silicone suits glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. We work on glass balustrade bases, glass-to-frame joints and glass-to-glass joints, and people most often call us about failed joints on frameless glass and stained, discoloured glazing silicone.
In a smaller place like Amersham on the Hill, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep air moving in the conservatory
- Check the gutters above the glazing for debris
- Keep scrapers and blades away from the silicone
- Look over the glazing joints once a year
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix, before water gets in.
Cracked glazing silicone means the joint has failed. Resealing now is a small job, compared with repairing damaged frames or plaster.
Windows and doors in Amersham on the Hill
Historic houses like Chenies Manor House (about 3.2 miles east) are a reminder that the area around Amersham on the Hill 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Dr Challoner's Grammar School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Amersham station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Leave it or put it right?
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. Around Amersham on the Hill, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
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’ll know the price before we begin.

Your questions about glazing silicone in Amersham on the Hill
Do you cover Amersham on the Hill for glazing silicone?
Yes, Amersham on the Hill is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work for landlords with property near Amersham station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can you just put new silicone over the old?
New silicone won’t bond to old silicone and water gets between the layers. The old bead always comes out first.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
