Floor joint sealing in Longniddry, done properly
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. Common call-outs are for cracked grout where a tiled floor needs a movement joint and open gaps along the bottom of skirting boards, across wet room & bathroom floors, tiled floors and commercial floors.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
All our work is covered by our one-year guarantee, wherever you are in East Lothian.

Joints and finishes in Longniddry homes
Across East Lothian, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
Around Longniddry, as everywhere, floor joint sealing is only as good as the preparation behind it.

The process
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most rooms, longer for large commercial floors.

- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied.
- We check the joints and explain the aftercare.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Longniddry: your questions answered
Can you help a landlord with a rental near Longniddry station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Can you do floor joint sealing in Longniddry?
Yes. We work across all of Scotland, and Longniddry is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Is caulk good enough for skirting?
Only on dry joints that don’t move. Caulk cracks as the floor moves, so the gap comes back. A flexible sealant is the better choice.
How soon can the floor be mopped?
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.
Can you add a movement joint to a tiled floor?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant.
Why does the gap under my skirting keep coming back?
Normally it’s movement: heating drying the timber, or a filler that’s too rigid. A flexible bead keeps up with the movement.
How much does floor joint sealing cost in Longniddry?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Bouncy or failing floorboards
- Tiles that have lifted or broken
- Cracked or broken concrete slabs
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.
Where we work in Longniddry
- Concrete floor joints
- Wet room & bathroom floors
- Tiled floors
- Thresholds
- Skirting boards
- Commercial floors
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the room once a year and look at the edges
- Mark off resealed joints in warehouses
- Do not paint over silicone
- Lift furniture rather than dragging it across joints
Lift furniture rather than sliding it over sealed joints. Sharp edges can cut the sealant especially in the first few days.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
How the job changes by surface
Commercial floors
In commercial buildings, we can plan floor joint work around opening hours. We can arrange out-of-hours work if the floor is busy.
Skirting boards
Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking in a colour to suit.
Landlords, agents and businesses in Longniddry
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
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.
