Floor joint sealing for homes and businesses in Sandness
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We work on tiled floors, commercial floors and thresholds, and common reasons people get in touch are threshold joints that have opened or worn and floor edges that trap water and grime.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning or an afternoon for most homes and we leave things clean and tidy. Outdoor work around Sandness depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- First, the floor type, the gap and the traffic are checked.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

Your questions about floor joint sealing in Sandness
Can you do floor joint sealing in Sandness?
Yes. Our work covers the whole of Scotland, and Sandness is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Sandness?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
How long does the job take?
Most jobs take a morning or an afternoon for most homes, including the preparation. Your quote will say how long we expect yours to take.
How long before the joint can take traffic?
That varies with the sealant and the room. Before we leave, we tell you when it can be walked on, mopped and driven over so there’s no guesswork.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you reseal concrete floor joints in an industrial unit?
Yes. We clean out the joints and reseal them with a product suited to the floor. Tell us what runs over the floor.

New homes and floors in Sandness
Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Around Sandness, as everywhere, floor joint sealing is only as good as the preparation behind it.

Common problems we fix in Sandness
When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, showing where a movement joint was needed.
Most people get in touch when they notice something like this:
- Tiled floors with no room to move
- Open joints that fill with dirt
- Threshold joints that have opened or worn
- Concrete floor joints that have broken down
If you look after a church, hall or community building such as St Margaret's Kirk and Graveyard, floor and skirting joints in halls and kitchens wear like any others.

How we quote for floor joint sealing
There’s no set price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- The number and length of the joints
- The old material and how stubborn it is
- Any working-time requirements on site
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
You do not need to know the technical terms. Just tell us:
- The type of property
- Photos by email, if that is easy
- The problem you’ve noticed
- The rough size of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
What happens if it’s left?
The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. 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.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- We leave the area clean and tidy
- You choose the colour before work begins
- More than 20 years in sealant work
