Glazing silicone for homes and businesses in Potten End
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We’re often asked to deal with a quick top-up bead that didn’t last and water tracking down the inner face of the glass, across shower screens, glass-to-glass joints and glass balustrade bases.
In a village or hamlet like Potten End, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Potten End questions
I let a flat near Berkhamsted station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Potten End?
Yes, Potten End is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
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. Brands we use include Arbo and Everbuild.
Are you fully insured?
Yes. Full insurance covers our work.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Why not top up the existing silicone?
Silicone does not stick to silicone, so a top-up soon lets water through. The old bead always comes out first.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. We do not install or replace the glass.
Can you replace a misted double-glazed unit?
We don’t replace glass. We look after the sealant joints and can tell you if a unit seems to have gone.
Why deal with it now?
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Where a wall is exposed, as many are in small places like Potten End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

You do not need to know the technical terms. Just tell us:

- Access, such as stairs, a lift or height

What glazing silicone looks like in Potten End
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.
In the older streets around Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Potten End CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Berkhamsted station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Failed flashing around a conservatory
- Rotten or badly damaged frames
- Condensation trapped between two panes
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
