Window mastic in Stoneywood, done properly

Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on timber windows & doors, patio & French doors and uPVC windows, and people most often call us about damp patches on the reveal after heavy rain and untidy mastic left by window fitters.

Outdoor sealant needs a dry surface, so window work around Stoneywood is planned around the weather. Let us know about access to every frame, including any upstairs.

You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Why it’s worth doing now in Stoneywood

Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Stoneywood, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

What window mastic looks like in Stoneywood

Under the Repairing Standard, private landlords in Scotland have to keep homes 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.

Schools such as Denny High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Larbert station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Avoid blasting the frames with a pressure washer
  • Do not paint over the silicone
  • Wipe condensation off the frames
  • Clear any debris from frame drain holes

Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.

What we can’t put right

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Broken hinges, locks or handles
  • A failed sealed unit that has misted up
  • Damp problems in the wall away from the window

Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

Joints and surfaces we work on

  • Timber windows & doors

What happens on the day

Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. Outdoor work around Stoneywood depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. First, we go round the frames with you and agree the list.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

Advice

How we quote for window mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The size of the job
  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • The old material and how stubborn it is

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.

What to tell us for a quote

When you contact us, these details help:

  • The rough size of the job
  • Pictures of the joints, sent by email
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
