Sand mastic in Carnbroe

How we handle sand mastic in Carnbroe

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on stone surrounds, timber door frames and period & listed homes, and people most often call us about silicone on a period window that looks wrong and window mastic to renew ahead of painting.

Mastic can only go onto a dry joint, so outside work in Carnbroe depends on the weather. Let us know about access to every frame, including any upstairs.

We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What affects the cost of sand mastic

Every job gets its own quote. This is what makes a difference:

  • Which sealant suits the joint
  • Whether old sealant or filler has to be cut out
  • Any mould that needs treating
  • How many areas need sealing

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

What we need to know

To help us quote quickly, please include:

  • Any access issues, like height or stairs
  • Where the job is, and your postcode
  • The type of property
  • What’s wrong with the joints now

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Why it’s worth doing now in Carnbroe

New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

What you get with us

  • More than 20 years in sealant work
  • Anti-fungal sanitary silicone in wet areas
  • We never seal over old sealant
  • Fully insured

How it works

On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work normally takes anything from a few hours to a full day, depending on how many windows. Somewhere like Carnbroe may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

Getting ready for the visit

  • Tell us about any water getting in
  • Mention if the joints have been sealed before
  • Clear items away from the joints we are working on

What we’re called out for in Carnbroe

Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.

People generally contact us after spotting one of these:

  • Cracked mastic round a front door frame
  • Draughty sash windows at the surround
  • Mastic dropping out of the joint
  • Tired mastic found when preparing windows for paint

If you live in an older home near Calder Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Aftercare tips

So the new joints stay in good condition:

  • Get any rot dealt with first
  • Clear gutters so water doesn’t pour onto the windows
  • Go gently near the mastic when preparing windows
  • Check the mastic when you check the paintwork

Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.

Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
