Glazing silicone in Coldharbour, done properly
A frameless shower screen depends on its silicone. The joint down the wall and the one along the tray are common leak points, and we reseal both. We work on conservatory frames, rooflights and glass-to-glass joints, and common reasons people get in touch are glass-to-glass joints that have split and drips on the inside of a conservatory window.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Coldharbour as anywhere.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Glazing silicone in Coldharbour: local notes
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 Queen's House (about 1.5 miles south) nearby, there’s older building stock in the area around Coldharbour as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Woolmore Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Canary Wharf station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Surface by surface
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
When to call us in Coldharbour
Using a sealant not made for glass causes many failures. Some products don’t bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.
If you can see any of these, it’s time to have the joints looked at:
- Leaks from the base of a shower screen
- Glass-to-glass joints that have split
- New silicone smeared over old sealant
- Conservatory leaks at frame and glazing joints
As a London address, Coldharbour can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- How much experience the applicator has
- Whether the sealant suits the joint
- Whether VAT is included
- How the colour is chosen
How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours, depending on how many joints need doing. In Coldharbour, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
How to prepare
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
