Glazing silicone for Denholm homes and businesses

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

About our glazing silicone in Denholm

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 work on rooflights, glass-to-frame joints and glass-to-glass joints, and people most often call us about failed sealant around rooflight glass and leaks where conservatory glass meets the frame.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.

Big or small, it’s backed by our one-year guarantee.

How the job changes by surface

Glass-to-frame joints

Old sealant is removed carefully from the glass and reseal with glazing silicone.

Glass-to-glass joints

You see these joints clearly, so we take care to leave a neat bead.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Quotes for glazing silicone in Denholm

The quote reflects the job in front of us. We look at:

  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • Working hours on commercial sites
  • The old material and how stubborn it is

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What to tell us for a quote

What to tell us when you ask for a quote:

When to call us in Denholm

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

Any of these means the joints need attention:

  • Failed sealant around rooflight glass
  • Cracked silicone between glass panels
  • Water getting into a conservatory at the joints
  • Mouldy sealant around glass panels

If you live in an older home near Minto Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What your quote should include

  • How the joint is cleaned and prepared
  • How long to leave it before use
  • Who turns up on the day
  • What happens if the job turns out different

Our hiring checklist

What glazing silicone looks like in Denholm

Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. 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.

If you look after a building such as Craigmount School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?

Glazing joints need a sealant made for the job. General-purpose sealant from a DIY shop may not suit glass or the frame, so we use neutral-cure glazing silicone. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Why book with us

  • Colour agreed with you before we start
  • Sealant colour chosen to suit
  • Homes, businesses and hotels
  • Quality sealants from Arbo and Everbuild

How it works

You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most jobs in most cases. Somewhere like Denholm may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. First, we check where the water gets in.
  2. The failed silicone is cut out without marking the glass or frame.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Keep children and pets away from the work area
  • Mention any parking rules near the property
