Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In an older home around Campbeltown, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Sand mastic in Campbeltown, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include mastic dropping out of the joint and window mastic to renew ahead of painting, across period & listed homes, timber door frames and sash and case windows.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Whatever the size of the job, you get the same one-year guarantee in Campbeltown and across Argyll and Bute.

Do you need sand mastic in Campbeltown?
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Tired mastic found when preparing windows for paint
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
In and around Campbeltown, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Masonry that needs repairing
- Putty and glazing repairs
- Decisions on consent for listed homes
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Campbeltown: your questions answered
Do you cover smaller places like Campbeltown?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is sand mastic in a coastal place like Campbeltown any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
What guarantee comes with the work?
Every job comes with our one-year guarantee, and we are fully insured.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Campbeltown, along with the rest of our area.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
What information do you need?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Campbeltown homes and the weather
Campbeltown is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Tirfergus House (about 3.6 miles south-west) are a reminder that the area around Campbeltown has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near Longrow Church and Hall, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

The process
On the day, we look over the joints with you first. We protect the surfaces around the joints before work begins. Most jobs take a few hours per window, depending on the condition of the joints. Around Campbeltown, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
