Deptford Glazing Silicone
Glazing silicone for conservatories, rooflights, glass panels and shower screens for homes and businesses in Deptford and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.

- A quick top-up bead that didn’t last
Glazing silicone in Deptford, done properly
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. If you have leaks from the base of a shower screen and rooflight joints letting water in, we can help, whatever the surface.
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 Deptford is something to talk through when you book.
Your job is guaranteed for a year, as with all our work.

What we are called out for in Deptford
Silicone will not bond to a dirty surface. If the glass and frame weren’t cleaned properly, the bead can peel away early.
Look out for any of the following:
- Drips on the inside of a conservatory window
- Water getting into a conservatory at the joints
- Stained, discoloured glazing silicone
- Rooflight joints letting water in
Homes close to St. Paul's include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- What product goes in the joint
- Is VAT in the price?

Glazing silicone in Deptford: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Historic houses like Queen's House (about 1 mile east) are a reminder that the area around Deptford has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Deptford station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Deptford is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Clear the conservatory gutters regularly
- Run a squeegee over the glass when you’re done
- Use gentle products around the joints
- Inspect the sealant on glazing annually
On shower screens, wipe or squeegee after use and keep the room ventilated. It helps stop mould getting into the silicone.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part and we will find out which.
DIY versus a professional finish
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, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the quote in Deptford

What happens on the day

All told, the work takes anything from an hour or two to most of a day, depending on the size of the job.

- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
How to prepare
