Leslie questions
Can you do floor joint sealing in Leslie?
Yes, Leslie is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Will you come out to Leslie?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work on commercial floors?
Yes, from warehouses and units to offices and shops. Work can be planned around your hours with out-of-hours work where needed.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How much does floor joint sealing cost in Leslie?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can grout be replaced with sealant on a tiled floor?
Often, yes. A crack along a grout line often means the floor needs room to move. We replace that grout with a flexible joint.
Floor joint sealing for homes and businesses in Leslie
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant. We work on commercial floors, wet room & bathroom floors and concrete floor joints, and people most often call us about gaps at thresholds between rooms and open joints that fill with dirt.
For a place like Leslie, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Tiled floors
Large or heated tiled floors need room to move. We replace grout with flexible sealant along the right lines in a matching colour.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Vacuum floor joints regularly to stop grit building up
- Do not paint over silicone
- Act on grout cracks that run in a straight line
- Avoid caulk in bathrooms and kitchens
Silicone sealant isn’t made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
What happens if it’s left?
Left open, concrete joints break down under traffic. A sealed joint supports the edges before they need a bigger repair. Around Leslie, water from a failed joint in an older stone home can soak into timber and plaster.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why book with us

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
New homes and floors in Leslie
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Across Fife, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.
Letting a property close to Markinch station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a building such as Glenwood High School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

What we’re called out for in Leslie
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Grout used at the floor edge instead of sealant
- Cracked caulk along skirting in bathrooms and kitchens
- Grout cracking in a straight line across a floor
- Open gaps along the bottom of skirting boards
If you look after a church, hall or community building such as Trinity Parish Church, joints in its floors, skirtings and thresholds need resealing as they wear.

What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours, depending on the length of joint. For a place like Leslie, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- The sealant goes in, chosen for the floor and coloured to suit it.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
