What floor joint sealing looks like in Carndu
Floors around Highland run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Rented homes near Stromeferry station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.
Carndu is in Highland. Our applicators cover floor joint sealing for homes and businesses in Carndu, as part of our work across Highland. 253 places in Highland are on our list, from the larger towns to small villages.
We cover every part of IV40 for floor joint sealing. We cover properties on Helen Street, Princes Street and William Street and the roads around them. We also cover the places around Carndu: Bundalloch (1 mile north-east), Dornie (1 mile south-west), Auchtertyre (3 miles west), Inverinate (5 miles south-east) and Reraig (5 miles west). Remote and island addresses need a little more planning, so tell us where you are when you ask for a quote.
What’s near Carndu

Floor joint sealing in Carndu
Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is normally the better choice, which isn’t made to be painted. We work on thresholds, wet room & bathroom floors and commercial floors, and people most often call us about grout cracking in a straight line across a floor and perimeter joints in tiled floors filled with grout.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
Big or small, you get the same one-year guarantee.

Common problems we fix in Carndu
A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands and joints fail.
Look out for these signs:
- Open gaps along the bottom of skirting boards
- Grout cracking in a straight line across a floor
- Gaps at thresholds between rooms
- Chipped and open joints in warehouse floors
For buildings such as St Duthuc's Roman Catholic Chapel, joints in its floors, skirtings and thresholds need resealing as they wear.
Before you book anyone
- When the joint can take water or movement
- How the joint is cleaned and prepared
- What product goes in the joint
- How much experience the applicator has
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get cracks along tile grout lines looked at early
- Keep dirt out of the joints
- Keep floor cleaning water to a minimum at the edges
- Ask before painting over a sealed joint
Avoid flooding the floor when you clean. Less water at the edges helps the joints last.
A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.
Carndu questions
I let a flat near Stromeferry station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Carndu?
Yes. Carndu is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
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 you can plan.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can you seal where the floor meets the bath panel?
Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone.
Different surfaces, different methods
Thresholds
Two different floors meeting at a threshold move differently. We bridge them with a flexible bead.
Tiled floors
Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines in a matching colour.
Why it’s worth doing now in Carndu
Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In an older home around Carndu, damp from a failed joint can get into timber and plaster.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

What else we do in Carndu
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours, depending on the length of joint, depending on the size of the job. Outside jobs in Carndu need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Clear the area around the work

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
