Glazing silicone for homes and businesses in Theydon Garnon
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. Common call-outs are for water running down inside the glass and black or yellowed silicone on glass joints, on glass-to-glass joints, rooflights and glass balustrade bases.
Mastic can only go onto a dry, clean joint, so window work in Theydon Garnon is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, whatever its size.

Theydon Garnon homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hill Hall (about 1.2 miles east) are a reminder that the area around Theydon Garnon has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Theydon Bois Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of All Saints, the joint between an old wall and a newer frame is generally the first place rain gets in.

Why deal with it now?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. Older cottages and farmhouses around Theydon Garnon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Neat joints and a tidy finish
- White, clear, grey or another colour, product permitting
- We never seal over old sealant
- Anti-fungal sanitary silicone in wet areas

Your questions about glazing silicone in Theydon Garnon
Is glazing silicone in Theydon Garnon guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover Theydon Garnon for glazing silicone?
Yes. We work across London and the South East, and Theydon Garnon is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Send us photos and we’ll take a look.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can you replace a misted double-glazed unit?
No, our work is the silicone. A glazier replaces glass and units.
Is it possible to redo the silicone on a shower screen?
Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep harsh solvents off the silicone
- Act on drips or damp patches early
- Keep conservatory gutters clear of leaves
- Ventilate the conservatory to cut condensation
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
Act on black or lifting silicone early. Peeling silicone lets water in behind and the problem grows.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job, including the tidy-up. Somewhere as small as Theydon Garnon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
How to get a quote
