Window mastic near Clachan of Campsie

When to call us in Clachan of Campsie

Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.

Any of these means the joints need attention:

  • Rushed sealant from a window installation
  • Damp patches on the reveal after heavy rain
  • Black, perished sealant on frames
  • Cracked internal joints between frame and plaster

For landlords with property near Milngavie station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How to choose a mastic man

Window mastic in Clachan of Campsie, done properly

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include gaps where the sill meets the wall and draughts coming in around windows and doors, across patio & French doors, timber windows & doors and uPVC windows.

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

You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Different surfaces, different methods

Aluminium frames

Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.

Frames and glazing around Clachan of Campsie

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

In the older streets around St Machan's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Keep timber frames painted
  • Wash the frames with mild soapy water
  • Ventilate rooms so frames don’t stay wet inside
  • Clear any debris from frame drain holes

A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

How it works

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a handful of frames, longer for a whole house. Outside jobs in Clachan of Campsie need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

  1. We check each frame and agree which ones need doing.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.
