Glazing silicone near South Norwood

Glazing silicone for homes and businesses in South Norwood

Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. If you have sealant that was laid over old silicone and failed and conservatory leaks at frame and glazing joints, we can help, whatever the surface.

Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.

Whatever the size of the job, you get the same 12-month guarantee.

When something else is needed

Before you book, it’s worth knowing the limits:

  • Condensation trapped between two panes
  • Cracked or broken glass
  • Leaks from the roof covering or flashing (a roofer’s job)

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Surfaces we seal

  • Rooflights
  • Conservatory frames
  • Glass balustrade bases
  • Glass-to-glass joints
  • Shower screens
  • Glass-to-frame joints

Aftercare tips

To keep the joints looking good and working properly:

  • Use a gentle glass cleaner and a soft cloth
  • Get a new leak looked at quickly
  • Clear the conservatory gutters regularly
  • Squeegee the shower screen after each use

Keep conservatory gutters clear so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.

Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

How we quote for glazing silicone

There’s no set price list, because no two jobs are the same. The quote depends on:

  • Whether the work is at height
  • Mould in or behind the old joints
  • Which sealant suits the joint
  • The number and length of the joints

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

You do not need to know the technical terms. Just tell us:

  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking

What happens on the day

  1. First we agree the joints to be done.
  2. We cut away the failed silicone.
  3. The surfaces are cleaned with a suitable solvent.
  4. We apply and tool the new silicone.
  5. We inspect the work and test it where we can.

How to prepare

  • Mention any sign-in or site rules at work premises

Managing a site like St Mark's Church of England Primary Academy? Then its window and door frames need their mastic kept sound, just like a home’s. As a London address, South Norwood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

When to call us in South Norwood

Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.

Most people get in touch when they notice one of these:

  • Water escaping where a screen meets the wall
  • Black or yellowed silicone on glass joints
  • Drips on the inside of a conservatory window
  • Leaking glazing joints on a rooflight

Rented homes near Norwood Junction station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
