About our sand mastic in Sandwick
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you have wind and rain getting in round a sash window and mastic that needs renewing before redecorating, we can help.
In and around a place like Sandwick, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Each job carries a 12-month guarantee, whatever its size.

Sandwick: your questions answered
Is Sandwick in your area for sand mastic?
Yes, Sandwick is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Does living near the coast affect sand mastic in Sandwick?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
Is the work guaranteed?
There’s a 12-month guarantee on every job, sand mastic included.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
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.
Signs you need sand mastic in Sandwick
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
- Crumbling sand mastic round a window
Around Sandwick, as everywhere, sand mastic is only as good as the preparation behind it.
What to look for in a quote
- Which colour the sealant will be
- How much experience the applicator has

What affects the quote in Sandwick
The price is agreed before any work begins. It’s based on:
- How easy the joints are to reach
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
When you contact us, it’s useful to know:
- If someone has resealed it before
- Whether it’s a home or a business
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
If you are in Sandwick and need sand mastic, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Landlords, agents and businesses in Sandwick

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for a single window, longer for several. Outdoor work around Sandwick 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.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Advice
Sandwick homes and the weather
Sandwick is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Whether the job is in Sandwick itself or nearby, the right material for each joint matters as much as a neat finish.
Sandwick is in the Shetland Islands. Jobs in Sandwick get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Sandwick is one of 63 places in the Shetland Islands where we work for sand mastic.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals 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.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.
