Frames and glazing around Coldharbour

Homes close to Christ Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Holmwood station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

About our glazing silicone in Coldharbour
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. Common call-outs are for sealant that was laid over old silicone and failed and failed joints on frameless glass, across shower screens, glass-to-glass joints and rooflights.
Homes in small places like Coldharbour often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. A failed bead lets water in.
How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. Somewhere like Coldharbour needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- 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.

Can I do it myself?
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 doesn’t work out, we can still put it right.
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.
Why it’s worth doing now in Coldharbour
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Older cottages and farmhouses around Coldharbour can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
