Glazing silicone in Whetstone, done properly
A frameless shower screen depends on its silicone. Leaks normally come from the wall joint or the tray joint and both get fresh anti-fungal silicone. Common call-outs are for water escaping where a screen meets the wall and stained, discoloured glazing silicone, across conservatory frames, glass-to-glass joints and rooflights.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
There’s a 12-month guarantee on every job.

How to look after the new joints
After the cure time, these simple habits help:
- Keep air moving in the conservatory
- Avoid strong solvents on or near the sealant
- Clean glass with a mild cleaner and a soft cloth
- Get a new leak looked at quickly
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Cracked glazing silicone means the joint has failed. Resealing now is a small job compared with fixing water damage later.
DIY sealant or a professional job?
If you’re 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 fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from an hour or two to most of a day, depending on the size of the job. In Whetstone, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit

Related advice
Why act early in Whetstone
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Whetstone, the repair is bigger than the sealant job would have been.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- Trusted Arbo and Everbuild sealants
- Neat joints and a tidy finish
- An ARBOMaster approved applicator
Surface by surface
Conservatory frames
Frame joints face sun and rain all year. Renewed sealant keeps water out.
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
What we can’t put right
In fairness, some problems need a different trade:
- A broken pane or roof panel
- A frame that needs repairing or replacing
- A sagging or failing conservatory roof
If in doubt, call 0345 464 0079 or email us and we will say what we think.

Whetstone homes and the weather
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. With historic houses such as Heath Hall (about 3.5 miles south) nearby, there’s older building stock in the area around Whetstone as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Queenswell Infant & Nursery School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St John include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Oakleigh Park station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
