About our glazing silicone in Catherington
Sealant on glazing does not last for ever. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. Typical jobs include sealant that was laid over old silicone and failed and silicone pulling away from the glass, across glass-to-glass joints, shower screens and glass balustrade bases.
Somewhere as small as Catherington, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a 12-month guarantee, the same in Catherington as everywhere else we work.

Catherington questions
Do you cover Catherington for glazing silicone?
Yes. Our work covers London and the South East, and Catherington is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work for landlords with property near Rowlands Castle station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What guarantee do I get?
You get our one-year guarantee to every job we do.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
How long will you be here?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer.
Can a conservatory leak be sealed?
It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
How to look after the new joints
After the cure time, these simple habits help:
- Don’t use a blade near the sealant
- Check the gutters above the glazing for debris
- Do not leave a drip for the next storm
- Keep air moving in the conservatory
Keep the new joints dry for as long as we advise so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Windows and doors in Catherington
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Rowlands Castle station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like Catherington Church of England Infant School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

What we need to know

Why it’s worth doing now in Catherington
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Around Catherington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Why us?
- Quality sealants from Arbo and Everbuild
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
- 180+ five-star Google reviews

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many joints need doing. Somewhere like Catherington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any tricky access
- Move anything stored near the joints
