About our sand mastic in Dornie
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. Typical jobs include gaps between timber frames and stone or brick and modern sealant on a period surround, across sash and case windows, period & listed homes and stone surrounds.
In and around a place like Dornie, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Your job is guaranteed for a year, as with all our work.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we quote for sand mastic
The price is agreed before any work begins. It’s based on:
- Any working-time requirements on site
- How much there is to do
- The product the joint needs
- How many areas need sealing
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
There’s no need for technical detail. Just tell us:
- How many joints, rooms or windows are involved
- The type of property
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Around Dornie, water from a failed joint in an older stone home can soak into timber and plaster.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Questions from Dornie
Do you cover smaller places like Dornie?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is sand mastic in a coastal place like Dornie any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Highland.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will talk you through it.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Windows and doors in Dornie
Dornie 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. Dornie is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
If you live in an older home near St Duthuc's Roman Catholic Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Around Dornie, as everywhere, sand mastic is only as good as the preparation behind it.

What the job involves on each surface
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. Around Dornie, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
