Floor joint sealing for homes and businesses in Strathmartine
Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed with a sealant suited to the movement and traffic. If you have concrete floor joints that have broken down and dirt and water collecting in open floor joints, we can put it right, on concrete floor joints, commercial floors and tiled floors alike.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Every job comes with a one-year guarantee.

What floor joint sealing looks like in Strathmartine
Floors around Dundee 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you let a flat or house near Dundee station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

Why it’s worth doing now in Strathmartine
Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Your questions about floor joint sealing in Strathmartine
Can you do floor joint sealing in Strathmartine?
Yes. We work across all of Scotland, and Strathmartine is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Is Strathmartine within the area you cover?
Yes, Strathmartine is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Strathmartine.
How soon can the floor be mopped?
We will tell you before we leave. That depends on the product, and walking on it generally comes before mopping or wheeled traffic.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Is caulk good enough for skirting?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.
How long will you be here?
Most jobs take a morning or an afternoon for most homes, including the preparation. Your quote will say how long we expect yours to take.
What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for most rooms, longer for large commercial floors. Somewhere like Strathmartine may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- The room is cleared along the joints so we can reach them.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor and tooled.
- Finally, we check the work and talk you through aftercare.
How to prepare
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Landlord and commercial work in Strathmartine
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When to call us in Strathmartine
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.
These are the problems we are asked about most:
- Skirting caulk that keeps splitting
- Failed joint filler in concrete floors
- Dirt and water collecting in open floor joints
- Tiled floors with no room to move
Managing a site like Baldragon Academy? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Is VAT in the price?
- Which sealant they’ll use, and why
- What happens if the job turns out different

What else we do in Strathmartine
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep caulk for dry, still joints only
- Keep floor cleaning water to a minimum at the edges
- Vacuum floor joints regularly to stop grit building up
- Don’t paint over silicone
Keep off the joint for the time we give you. Light foot traffic is generally fine sooner than wet cleaning or wheels, and we will tell you both.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- Leaks from a failed tanking system
- Concrete repairs beyond the joint
- Bouncy or failing floorboards
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.
