About our floor joint sealing in Gretna
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk generally cracks where there’s movement, so we close it with a flexible sealant instead. If you’re dealing with open joints around bathroom floor edges and concrete floor joints that have broken down, we can help, on concrete floor joints, tiled floors and wet room & bathroom floors alike.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you are 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 doesn’t work out, we can still put it right.
Gretna: your questions answered
Can you help a landlord with a rental near Gretna Green station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is Gretna in your area for floor joint sealing?
Yes, Gretna is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
How soon can the floor be mopped?
Follow the cure time we give you. Feet are normally fine first, then mopping, then heavy wheels, depending on the product.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
What causes gaps between the floor and skirting?
Usually it’s movement: timber drying in winter, floors settling, or caulk that can’t stretch. A flexible sealant stays closed as the floor moves.
Different surfaces, different methods
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.
Thresholds
Thresholds take daily traffic, so the sealant has to be tough as well as flexible.
New homes and floors in Gretna
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. Floors around Dumfries and Galloway run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
For landlords with property near Gretna Green station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal.

- We take out any old caulk, sealant or grout along the line.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.

Call for a quick quote. What matters most is:
- How many rooms, windows or areas are involved
- The size of the job
- Any working-time requirements on site
- Whether the work is at height
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
What we need to know
To help us quote quickly, please include:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Where the property is
- Access, such as stairs, a lift or height
We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.
What happens if it’s left?
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk.

What we are called out for in Gretna
An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean and can reach the subfloor.
Most people get in touch when they notice one of these:
- Caulk that has cracked where the floor moves
- Gaps at thresholds between rooms
- Gaps between floors and kitchen plinths
- Skirting that has pulled away from the floor
Community buildings like St Andrew's Church of Scotland are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
