Sand mastic near Dalwhinnie

How the visit works

At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a single window, longer for several, depending on the size of the job. Somewhere like Dalwhinnie may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Preparing for the visit

About our sand mastic in Dalwhinnie

Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. Typical jobs include window mastic to renew ahead of painting and old cement repairs round a window that have failed, on period & listed homes, brick reveals and tenement windows.

In and around a place like Dalwhinnie, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.

The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

Sand mastic in Dalwhinnie: local notes

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, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.

Rented homes near Dalwhinnie station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Dalwhinnie is about 37 miles south of Inverness, in Highland.

Dalwhinnie is one of 253 towns and villages in Highland we cover. For nearby work, see our Dundee page.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Look over the window mastic once a year
  • Keep sills and gutters clear so water drains away
  • Keep modern sealant off the mastic
  • Leave the new mastic unpainted

Check the mastic when you check the paintwork. Small cracks are easier to deal with early.

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

DIY sealant or a professional job?

If you do try it yourself, take your time over the 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.

Some sealant jobs are within reach of a careful DIYer, 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.

Common problems we fix in Dalwhinnie

Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.

Any of these means the joints need attention:

  • Mastic dropping out of the joint
  • Silicone on a period window that looks wrong
  • Open joints round the window box
  • Gaps round a timber door in stone or brick

In and around Dalwhinnie, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Choosing a sealant specialist

What happens if it’s left?

Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In an older home around Dalwhinnie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.

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