Glazing silicone in Slaugham: local notes
Historic houses like Tyes Place (about 1.8 miles east) are a reminder that the area around Slaugham 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Balcombe station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like Warninglid Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Glazing silicone in Slaugham, done properly
Not every silicone suits glass. We use a neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. Typical jobs include split or lifting silicone on glass and drips on the inside of a conservatory window, on glass-to-frame joints, rooflights and glass-to-glass joints.
In a village or hamlet like Slaugham, 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.
Big or small, it’s backed by our 12-month guarantee in Slaugham and across West Sussex.

What else we do in Slaugham
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the gutters above the glazing for debris
- Look over the glazing joints once a year
- Do not leave a drip for the next storm
- Avoid scraping close to the bead
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we’ll tell you which.
The process
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours, depending on how many joints need doing. In a small place like Slaugham, access is normally the main thing to plan. 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.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Why act early in Slaugham
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. In a small place like Slaugham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

FAQs for Slaugham
I let a flat near Balcombe station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can you do glazing silicone in Slaugham?
Yes, Slaugham is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you replace glass?
No. A misted unit has failed inside and needs replacing by a glazier.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Why not top up the existing silicone?
Silicone does not stick to silicone, so a top-up soon lets water through. We cut out the old sealant first.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
