Glazing silicone in Stockwell
Sealant on glazing doesn’t last for ever. Weather and movement take their toll and cracked joints let water in. Resealing puts that right. Common call-outs are for water escaping where a screen meets the wall and water running down inside the glass, on shower screens, glass balustrade bases and glass-to-glass joints.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Stockwell is something to talk through when you book.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Stockwell
There’s no set price list, because no two jobs are the same. The quote depends on:
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Which sealant suits the joint
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or email us.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Where the property is
We quote each job on its own. Just ring 0345 464 0079 or drop us an email with the details.
What sealant work can’t fix
We won’t take on work that won’t last, so these are the limits:
- A roof that has moved or dropped
- Cracked or broken glass
- Water coming through the roof rather than a sealant joint

Common problems we fix in Stockwell
Some conservatory leaks aren’t sealant at all: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
Most people get in touch after spotting something like this:
- Silicone pulling away from the glass
- Drips on the inside of a conservatory window
- Leaks where conservatory glass meets the frame
- Leaking glazing joints on a rooflight
As a London address, Stockwell can be tricky for parking: let us know about parking bays, permits or a driveway.

Surface by surface
Rooflights
Rooflights get the full force of the weather. Its sealant ages faster than vertical joints.
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Windows and doors in Stockwell
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. With historic houses such as Carlyle's House (about 2.4 miles north-west) nearby, there’s older building stock in the area around Stockwell as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Brixton station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. Managing a site like St Andrew's Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
