What the job involves on each surface
Skirting boards
Skirting-to-floor joints are a regular job for us. We take out any cracked caulk before sealing.
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
How we handle floor joint sealing in Sanndabhaig
Tiled floors can crack along the grout when there’s no room for movement. We can turn a line of grout into a movement joint by replacing it with flexible sealant in a matching colour. Typical jobs include rigid edge joints in tiled floors and threshold joints that have opened or worn, across concrete floor joints, wet room & bathroom floors and thresholds.
Around smaller Scottish places like Sanndabhaig, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All our work comes with our 12-month guarantee, wherever you are in Na h-Eileanan Siar.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Look at floor joints each spring
- Use furniture pads near skirting
- Use a well-wrung mop rather than flooding the floor
- Mark off resealed joints in warehouses
Do not paint over silicone. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the floor safer.
How we quote for floor joint sealing

What happens if it’s left?
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most rooms, longer for large commercial floors. Outdoor work around Sanndabhaig depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor.
- Finally, we check the work and talk you through aftercare.
Before we arrive
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

What floor joint sealing looks like in Sanndabhaig
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. Island jobs need planning around ferries and the weather, so the more notice, the better.
In and around Sanndabhaig, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.

Sanndabhaig: your questions answered
Is Sanndabhaig within the area you cover?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Is floor joint sealing in Sanndabhaig guaranteed?
All our work, in Sanndabhaig and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Is caulk good enough for skirting?
Not where the floor moves or gets wet. It splits once the floor shifts. A flexible sealant lasts longer there.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we’re called out for in Sanndabhaig
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges and the joint gets wider.
Keep an eye out for these signs:
- Chipped and open joints in warehouse floors
- Dirt and water collecting in open floor joints
- Gaps between floors and kitchen plinths
- Cracked grout where a tiled floor needs a movement joint
For jobs in and around Sanndabhaig, choosing the right material for each joint is as important as a tidy finish.
