Why it’s worth doing now in Canterbury

A leaking joint will not fix itself. Left, water can mark floors, damage plaster and rot timber, so it pays to deal with it early. For landlords in Canterbury, failed sealant soon turns into tenant complaints about mould, damp or draughts. Sorting it between tenancies is easier than dealing with it mid-let.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why us?

  • Colour picked to suit the job
  • A 12-month guarantee on all work
  • Old sealant always removed completely
  • We leave the area clean and tidy

How we handle glazing silicone in Canterbury

Frameless shower screens rely on sealant to keep water in. Leaks generally come from the wall joint or the tray joint, and we reseal both. Common call-outs are for shower screens leaking along the wall or tray and leaking glazing joints on a rooflight, across glass-to-frame joints, conservatory frames and rooflights.

With a large rental market, Canterbury has plenty of windows that landlords need to keep weathertight. Cracked or missing mastic round a frame is a common cause of damp patches and draughts.

A one-year guarantee comes as standard.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

What we are called out for in Canterbury

New silicone over old silicone will not bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.

Any of these means the joints need attention:

  • Water getting into a conservatory at the joints
  • Rooflight joints letting water in
  • A quick top-up bead that didn’t last
  • Split or lifting silicone on glass

Schools such as St Peter's Methodist Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Choosing a sealant specialist

Looking after it afterwards

Aftercare is simple, and it makes a real difference:

  • Keep air moving in the conservatory
  • Avoid strong solvents on or near the sealant
  • Look over the glazing joints once a year
  • Avoid scraping close to the bead

Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.

Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.

How the visit works

Before we leave, we go over the finished joints with you. The visit itself usually takes anything from an hour or two to most of a day, depending on the size of the job, depending on the amount of work. In central Canterbury, parking can be tight, so tell us about driveways, permits or nearby car parks. For flats, mention stairs, lifts and shared entrances as well.

  1. We start by finding the leak and making sure sealant is the cause.
  2. The old sealant is removed from the glass and frame without scratching them.
  3. We clean the joint with a solvent that suits the glass and frame.
  4. New glazing silicone goes in and is tooled to a neat finish.
  5. The finished joints are checked and, where it’s safe, tested with water.

Before we arrive

  • Move anything stored near the joints
  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any water getting in

What glazing silicone looks like in Canterbury

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Letting a property close to Canterbury East station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
