New homes and floors in Canongate
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. 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. That is why the skirting and threshold joints need a flexible seal.
If you look after a building such as Old Royal High School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like Kirk of the Canongate are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Rented homes near Edinburgh Waverley station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.

Floor joint sealing in Canongate, done properly
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant. We work on commercial floors, wet room & bathroom floors and concrete floor joints, and common reasons people get in touch are skirting that has pulled away from the floor and concrete floor joints that have broken down.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. Those joints, and plot mastic for developers, are part of the work we cover in Canongate.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Related advice
What the job involves on each surface
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it if it’s in the right place.
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again.
Landlord and commercial work in Canongate
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Floor joints left open collect dirt that is hard to clean out and makes the floor look worn. Sealed joints are easier to keep clean and finishes the floor. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Canongate, damp can travel a long way before it shows.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

FAQs for Canongate
Is Canongate in your area for floor joint sealing?
Yes. Our work covers the whole of Scotland, and Canongate is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Do you work for landlords with property near Edinburgh Waverley station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you insured?
Yes. Full insurance covers our work.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Why does the gap under my skirting keep coming back?
It’s normally the floor moving: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible sealant stays closed as the floor moves.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
