Glazing silicone in North Wembley

Glazing silicone in North Wembley, done properly

We do not replace glass, and misting between panes means a failed sealed unit. Our work is the sealant joints, which is where many leaks start. If you have cracked silicone between glass panels and mouldy sealant around glass panels, we can help.

London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.

All our work comes with a one-year guarantee, wherever you are in Greater London.

Why act early in North Wembley

Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in North Wembley, the repair is bigger than the sealant job would have been.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Your questions about glazing silicone in North Wembley

Can you do glazing silicone in North Wembley?

Do you work for landlords with property near Wembley Central station?

Can you reseal the base of a glass balustrade?

Yes. The old sealant is removed and the joint resealed using a sealant that suits the materials.

Is it messy?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Do you have insurance?

Yes. Mr Mastic is fully insured.

Can you replace a misted double-glazed unit?

No. Misting between panes means the sealed unit has failed, and a glazier needs to replace it.

Do you reseal glass shower screens?

Yes, it’s a common job. The screen is resealed with anti-fungal silicone made for wet areas.

Why not top up the existing silicone?

Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.

Frames and glazing around North Wembley

In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

In the older streets around Church of St John, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Wembley Central station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What we cannot put right

We’d rather tell you now than do work that will not last, so these are the limits:

  • Cracked or broken glass
  • Water coming through the roof rather than a sealant joint
  • A sagging or failing conservatory roof

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Where we work in North Wembley

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

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Look over the glazing joints once a year
  • Get a new leak looked at quickly
  • Run a squeegee over the glass when you are done
  • Stick to mild cleaners on glass

Check the joints once a year. Catching a split early keeps the repair small, before water gets in.

Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.

Quotes for glazing silicone in North Wembley

We quote each job individually. This is what makes a difference:

  • Any working-time requirements on site
  • The product the joint needs
  • The size of the job
  • How easy the joints are to reach

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Helping us quote

What to tell us when you ask for a quote:

  • The address or postcode of the job
  • How many joints, rooms or windows are involved
  • Whether it has been sealed before
  • The type of property

It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or send us an email.

The process

Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First, we check where the water gets in.
  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. Each joint is checked and, where possible, water-tested.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints
  • For business premises, tell us about site rules or sign-in
