Glazing silicone in Leslie

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

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.

Glazing silicone in Leslie, done properly

Glass and frames expand and contract differently, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We are often asked to deal with cracked silicone between glass panels and failed sealant around rooflight glass, across shower screens, conservatory frames and glass-to-glass joints.

Mastic can only go onto a dry joint, so outside work in Leslie depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.

There’s a 12-month guarantee on every job, large or small.

What happens on the day

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours, depending on how many joints need doing, including the tidy-up. Somewhere like Leslie may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. We look at the glazing and agree which joints need resealing.
  2. We cut away the failed silicone.
  3. The surfaces are cleaned with a suitable solvent.
  4. New glazing silicone goes in and is finished neatly.
  5. The joints are checked before we leave.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any previous sealing or DIY attempts
  • Let us know about parking restrictions

Looking after it afterwards

So the new joints stay in good condition:

  • Clear the conservatory gutters regularly
  • Do not use a blade near the sealant
  • Use gentle products around the joints
  • Ventilate the conservatory to cut condensation

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

Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

When it isn’t the sealant

It helps to know what we cannot do too:

  • A broken pane or roof panel
  • Condensation trapped between two panes
  • Water coming through the roof rather than a sealant joint

If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

What the job involves on each surface

Rooflights

A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.

Glass-to-glass joints

Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.

Frames and glazing around Leslie

Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Letting a property close to Markinch station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. Schools such as Glenwood High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Trinity Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
