Floor joint sealing for homes and businesses in Star
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant. If you’re dealing with tiled floors with no room to move and concrete floor joints that have broken down, we can put it right, on wet room & bathroom floors, concrete floor joints and thresholds alike.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
Our work is backed for twelve months.

The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job usually takes a few hours for most rooms, longer for large commercial floors, and we explain the cure time before we leave. Outdoor work around Star depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.

Why act early in Star
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In a place like Star, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in Star
- Sealant colour chosen to suit

What affects the cost of floor joint sealing
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Access and height
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What we need to know
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.
Joints and finishes in Star homes
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’s why the skirting and threshold joints need a flexible seal. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

Why does the gap under my skirting keep coming back?
Floors shrink and settle, especially in the first year or two and through the heating season. Caulk tends to crack; a flexible sealant does not.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Where do you work from?
We work from Crawley. Our applicators cover Star, along with the rest of our area.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
How do I get a quote for floor joint sealing in Star?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you need floor joint sealing in Star?
A floor laid tight to the walls has no room to move. As it expands, the edges lift or crack.
Most people get in touch after spotting one of these:
- Perimeter joints in tiled floors filled with grout
- Failed joint filler in concrete floors
- Open joints around bathroom floor edges
- Cracked caulk along skirting in bathrooms and kitchens
If you let a flat or house near Markinch station, gaps at skirtings and thresholds are worth sealing between tenancies.

- How the joint is cleaned and prepared
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep caulk for dry, still joints only
- Vacuum floor joints regularly to stop grit building up
- Act on grout cracks that run in a straight line
- Ask before painting over a sealed joint
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead especially in the first few days.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.
What the job involves on each surface
Concrete floor joints
We clean concrete joints out thoroughly before sealing, vacuuming them clean. We fit backing where needed.
Thresholds
Thresholds take daily traffic, so the sealant has to be tough as well as flexible and tool it flush.
Landlords, agents and businesses in Star
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
