Sandhead Sand Mastic
We cover Sandhead for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.

- Gaps where the frame meets the masonry
Sand mastic in Sandhead, done properly
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We are often asked to deal with mastic worn away on windows facing the weather and mastic dropping out of the joint, across brick reveals, tenement windows and timber door frames.
Mastic can only go onto a dry joint, so outside work in Sandhead depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we are called out for in Sandhead
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Most people get in touch after spotting one of these:

Sandhead questions
Is sand mastic in a coastal place like Sandhead any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover Sandhead for sand mastic?
Yes. Our work covers the whole of Scotland, and Sandhead is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
What sand mastic looks like in Sandhead
Sandhead 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. 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.
Whether the job is in Sandhead itself or nearby, the right material for each joint matters as much as a neat finish.

What affects the cost of sand mastic
Your quote is based on your job. We take into account:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many areas need sealing
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- A few pictures by email, if you can
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- If someone has resealed it before

Why act early in Sandhead
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a place like Sandhead, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- More than 20 years in sealant work
- Approved under the ARBOMaster scheme
- Domestic, commercial and hotel work
- Old sealant always removed completely

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:
- Damaged stone surrounds
- Rotten sashes, sills or window boxes (a joiner’s job)
- Whether work needs listed building consent
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several. Outdoor work around Sandhead depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Mention any tricky access
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
