Floor joint sealing in Biggar
We seal floor joints in homes, offices and commercial buildings across Biggar. We start by checking the floor type and the joint, because the right sealant depends on both. If you have gaps at thresholds between rooms and perimeter joints in tiled floors filled with grout, we can put it right, whatever the surface.
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.
All our work is covered by our one-year guarantee, wherever you are in South Lanarkshire.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Use furniture pads near skirting
- Don’t paint over silicone
- Keep floor cleaning water to a minimum at the edges
- Mark off resealed joints in warehouses
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead.
Cracks along tile grout lines come back unless the movement is dealt with. A flexible joint added early helps protect the tiles themselves.
How it works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a morning or an afternoon for most homes. Outside jobs in Biggar need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and tooled.
- We check the joints and explain the aftercare.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Related advice
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracked or broken concrete slabs
- Bouncy or failing floorboards
- Failed waterproofing under a wet room floor
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Tiled floors
- Skirting boards
- Concrete floor joints
- Commercial floors
- Thresholds
- Wet room & bathroom floors
What happens if it’s left?
Left open, concrete joints break down under traffic. A sealed joint supports the edges. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Should I try it myself first?
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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

How the job changes by surface
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it.
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. We bridge them with a flexible bead.
What floor joint sealing looks like in Biggar
Floors around South Lanarkshire run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For site and facilities teams at buildings such as Biggar High School, floor and threshold joints in busy corridors wear quickly and are best resealed early. If you look after a church, hall or community building such as Biggar Church, floor and skirting joints in halls and kitchens wear like any others.

Biggar questions
Will you come out to Biggar?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do floor joint sealing in Biggar?
Yes. We work across all of Scotland, and Biggar is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
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.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is caulk good enough for skirting?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.
