Glazing silicone in Canonbury: local notes

Historic houses like Sutton House (about 1.7 miles east) are a reminder that the area around Canonbury has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.

As a London address, Canonbury can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Canonbury station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Glazing silicone in Canonbury, done properly

Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant can’t fix, we will tell you. We work on conservatory frames, glass-to-glass joints and glass balustrade bases, and common reasons people get in touch are sealant that was laid over old silicone and failed and shower screens leaking along the wall or tray.

Many London homes are flats, with windows high above the street. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking, and access in Canonbury is something to talk through when you book.

You get a 12-month guarantee, the same in Canonbury as everywhere else we work.

  • Whether old sealant or filler has to be cut out
  • How easy the joints are to reach
  • Any working-time requirements on site

  • Whether it’s a home or a business
  • If someone has resealed it before

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, call 0345 464 0079 or send us an email.

What happens on the day

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most jobs. In a London area like Canonbury, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. We trace the leak and confirm it’s a sealant joint.
  2. We remove the old sealant carefully.
  3. The joint is cleaned and degreased.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

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 fails, we can still redo it.

Common problems we fix in Canonbury

Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.

Most people get in touch after spotting something like this:

  • New silicone smeared over old sealant
  • Water getting into a conservatory at the joints
  • Split or lifting silicone on glass
  • Water tracking down the inner face of the glass

For an older house near a landmark such as St Paul's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What your quote should include

  • Is VAT in the price?
  • How the surfaces are prepared before sealing
  • The length of the guarantee
  • Who turns up on the day
