Aftercare tips

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

  • Use gentle cleaners on frames and sealant
  • Keep drainage slots and sill grooves clear
  • Keep paint and stain on wooden frames in good order
  • Walk round the house once a year and look at the joints

A yearly look round the frames is enough. Small splits are simple to catch before they leak.

Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

Common call-outs are for whistling draughts around closed windows and a bead that doesn’t match the frame, across window sills, composite doors and timber windows & doors.

Outdoor sealant needs a dry surface, so window work around Calderbank is planned around the weather. Tell us about access to all the windows and doors, upstairs included.

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Why deal with it now?

Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In an older home around Calderbank, damp from a failed joint can get into timber and plaster.

What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

What happens on the day

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes most of a day for a typical house, less for a few frames. Somewhere like Calderbank may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. First we look at every frame and agree the list.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Where gaps are deep, backing rod goes in first.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Finally we tidy up and check each joint.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • On commercial sites, let us know about site rules
  • Mention any leaks or damp you’ve noticed

Do you need window mastic in Calderbank?

Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.

It’s worth asking for a quote if you see:

  • Cracked or shrunken mastic around the frame
  • Untidy mastic left by window fitters
  • A bead that doesn’t match the frame
  • Rain getting in at the frame or under the sill

Schools such as Brannock High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What to look for in a quote

  • Whether all the old sealant comes out first
  • What the cure time is
  • How the joint is cleaned and prepared
  • What guarantee comes with the work

If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

Joints and surfaces we work on

What window mastic looks like in Calderbank

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, often pointed into the wall with traditional sand mastic.

Letting a property close to Airdrie station? Then renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Calderbank 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.
