Floor joint sealing in Moredun, done properly
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. If you have skirting caulk that keeps splitting and failed seals where bathroom floors meet baths and panels, we can put it right, on commercial floors, tiled floors and thresholds alike.
In older Scottish city flats, floors are often timber over joists, so skirting joints open and close through the year. In Moredun, a flexible sealant suits those joints better than filler.
There’s a 12-month guarantee on every job.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How it works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes a few hours for most rooms, longer for large commercial floors for a typical job. Inside a flat in Moredun, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

What else we do in Moredun
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Use a well-wrung mop rather than flooding the floor
- Vacuum floor joints regularly to stop grit building up
- Lift furniture rather than dragging it across joints
- Get cracks along tile grout lines looked at early
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up before they spread.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the floor safer.
What happens if it’s left?
Dirt builds up in open joints. A neat sealed joint is easier to clean and finishes the floor. In a tenement flat in Moredun, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What you get with us
- You choose the colour before work begins
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- Any old sealant cut out fully, not covered over

Signs you need floor joint sealing in Moredun
An open floor joint fills with dirt and water. In kitchens and bathrooms, mop water gets into the gap.
If you can see any of these, it’s time to have the joints looked at:
- Gaps at thresholds between rooms
- Gaps opening between the floor and skirting
- Grout used at the floor edge instead of sealant
- Failed seals where bathroom floors meet baths and panels
Managing a site like Liberton High School? Then entrance and corridor floor joints take a lot of traffic.

Questions from Moredun
Can you help a landlord with a rental near Shawfair station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Is there a guarantee on floor joint sealing in Moredun?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Why does the gap under my skirting keep coming back?
Movement from drying timber and settling floors pulls the skirting and floor apart. Rigid fillers split, so we use a flexible sealant.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you reseal concrete floor joints in an industrial unit?
Yes. Concrete floor joints in warehouses and units are part of our work. We will talk through the traffic and choose a sealant suited to it.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What affects the quote in Moredun

- Mould in or behind the old joints

- The type of property
- Where the job is, and your postcode
- Any access issues, like height or stairs
Every job is quoted individually, so start by telling us what you need. Simply send an email to info@mrmastic.co.uk and describe the job.
New homes and floors in Moredun
Across Edinburgh, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
For landlords with property near Shawfair station, gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as Liberton Parish Church, floor and skirting joints in halls and kitchens wear like any others.
