DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we handle sand mastic in Barncluith
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead and we’ll explain which is best for yours. If you’re dealing with a silicone bead on a sash window that spoils the look and crumbling sand mastic round a window, we can put it right.
Outdoor sealant needs a dry surface, so window work around Barncluith is planned around the weather. Let us know about access to every frame, including any upstairs.
All our work comes with our 12-month guarantee.

Advice
Barncluith questions
Is Barncluith in your area for sand mastic?
Yes, Barncluith is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Will you come out to Barncluith?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
What guarantee comes with the work?
All our work has a one-year guarantee, and we’re fully insured.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why act early in Barncluith
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. 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.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.

Barncluith homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Historic houses like Cambusnethan House (about 3.3 miles east) are a reminder that the area around Barncluith has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Cadzow Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Hamilton Central station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Hamilton Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

- Planning or listed building consent (your local planning authority decides)
