Sand mastic in Birsemore

Across Birsemore, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on sash and case windows, period & listed homes and timber door frames, and the jobs we see most are a silicone bead on a sash window that spoils the look and mastic worn away on windows facing the weather.

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

Every job comes with a one-year guarantee, wherever you are in Aberdeenshire.

Windows and doors in Birsemore

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.

For site and facilities teams at buildings such as Aboyne Academy, larger buildings have plenty of frames, and the mastic around each one ages.

Birsemore is about 11 miles west of Banchory, in Aberdeenshire. Birsemore gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee.

What happens on the day

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours per window, depending on the condition of the joints. Outside jobs in Birsemore 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. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Getting ready for the visit

  • Let us know about parking restrictions
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any water getting in

Quotes for sand mastic in Birsemore

We do not publish a price list, because jobs vary so much. The quote depends on:

  • The size of the job
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating
  • When we can work, for business premises

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Asking for a quote

You do not need to know the technical terms. Just tell us:

  • Roughly how big the job is
  • Whether it’s a home or a business
  • Where the job is, and your postcode
  • Any access issues, like height or stairs

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, drop us a line at info@mrmastic.co.uk.

Why act early in Birsemore

Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Around Birsemore, water from a failed joint in an older stone home can soak into timber and plaster.

Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

Common problems we fix in Birsemore

Timber swells and shrinks with the weather. The movement cracks the mastic over time.

Keep an eye out for these signs:

  • Crumbling sand mastic round a window
  • Draughts and rain around sash boxes
  • Cracked mastic round a front door frame
  • A silicone bead on a sash window that spoils the look

For an older house near a landmark such as St Machar's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Questions to ask before you book

  • Who turns up on the day
  • Which sealant they’ll use, and why
  • Is the old sealant removed completely?
  • How the colour is chosen

Our hiring checklist

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

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

Birsemore questions

Will you come out to Birsemore?

Yes, Birsemore is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do sand mastic in Birsemore?

Yes. We work across all of Scotland, and Birsemore is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.

Is consent needed for window work on a listed home?

Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.

Is it worth trying it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

How long does sand mastic take?

That depends on how much there is to do, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.

Is the work guaranteed?

You get our 12-month guarantee to all our work.

Is it possible to paint over sand mastic?

It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.

Looking after it afterwards

Looking after new joints is easy:

  • Avoid heavy scraping on the mastic joint
  • Do not paint over the new mastic
  • Have rotten timber repaired before new mastic goes in
  • Keep sills and gutters clear so water drains away

Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.

It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
