What glazing silicone looks like in Bermondsey

With historic houses such as Mansion House (about 1.3 miles north-west) nearby, there’s older building stock in the area around Bermondsey as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.

For landlords with property near London Bridge station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around St Mary Magdalen Bermondsey, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How we handle glazing silicone in Bermondsey

Across Bermondsey, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you have glass-to-glass joints that have split and rooflight joints letting water in, we can help, on glass balustrade bases, glass-to-glass joints and glass-to-frame joints alike.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.

Every job comes with a one-year guarantee.

How to look after the new joints

Good habits help new joints last longer. A few tips:

  • Look over the glazing joints once a year
  • Clear the conservatory gutters regularly
  • Keep air moving in the conservatory
  • Use gentle products around the joints

Keep the new joints dry for as long as we advise so the silicone can set properly. After that, clean glass with a mild cleaner.

A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.

For landlords and businesses

For anyone letting property in or around Bermondsey, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.

How we quote for glazing silicone

Your quote is based on your job. We look at:

  • Working hours on commercial sites
  • Any mould that needs treating
  • The size of the job
  • Which sealant suits the joint

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Photos by email, if that’s easy
  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business
  • Where the job is, and your postcode

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or drop us an email.

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What happens on the day

Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. In Bermondsey, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We trace the leak and confirm it’s a sealant joint.
  2. The failed silicone is cut out without marking the glass or frame.
  3. The joint is cleaned and degreased.
  4. A neutral-cure glazing silicone is applied and tooled.
  5. Each joint is checked and, where possible, water-tested.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

Advice

How the job changes by surface

Shower screens

A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.

Glass-to-frame joints

The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.

When to call us in Bermondsey

Shower screen silicone gets wet every day. Mould gets into it and the joint starts to lift.

The problems people normally mention when they call are:

  • Water getting into a conservatory at the joints
  • Silicone pulling away from the glass
  • Drips on the inside of a conservatory window
  • Failed sealant around rooflight glass

For site and facilities teams at buildings such as Boutcher Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
