Trinafour Sand Mastic
Professional sand mastic in and around Trinafour, with old sealant always removed completely.
- Mastic worn away on windows facing the weather
- Window mastic to renew ahead of painting
- Mastic round period door frames that has failed
Leave it or put it right?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Sand mastic in Trinafour, done properly
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on stone surrounds, period & listed homes and timber door frames, and the jobs we see most are mastic worn away on windows facing the weather and mastic that needs renewing before redecorating.
In and around a place like Trinafour, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
Each job carries a 12-month guarantee, large or small.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention any tricky access
- Clear the area around the work
- Keep children and pets away from the work area

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, 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.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Windows and doors in Trinafour
The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Trinafour, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Trinafour questions
Is there a guarantee on sand mastic in Trinafour?
All our work, in Trinafour and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Trinafour within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
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.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How much does sand mastic cost in Trinafour?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk with a short description of the job.

Quotes for sand mastic in Trinafour
Every job gets its own quote. These are the things that affect it:
- The old material and how stubborn it is
- The number and length of the joints
- Whether the work is at height
- Mould in or behind the old joints
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know

- Access, such as stairs, a lift or height

Signs you need sand mastic in Trinafour
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
It’s worth asking for a quote if you see:
- Gaps between timber frames and stone or brick
- Mastic worn away on windows facing the weather
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
Whether the job is in Trinafour itself or nearby, the right material for each joint matters as much as a neat finish.
