Why it’s worth doing now in St Mary's
Filling a skirting gap with caulk looks fine at first, so the gap reappears. A flexible sealant moves with the floor, so the joint stays closed. In an older home around St Mary's, damp from a failed joint can get into timber and plaster.

Floor joint sealing in St Mary's
We seal floor joints in homes, offices and commercial buildings across St Mary's. We start by checking the floor type and the joint, since that decides which sealant suits. If you are dealing with cracked grout where a tiled floor needs a movement joint and concrete floor joints that have broken down, we can help, on tiled floors, concrete floor joints and thresholds alike.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Each job carries a 12-month guarantee.

The process
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours, depending on the length of joint. Outdoor work around St Mary's depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- The chosen sealant goes in, coloured to suit the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions

Advice
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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, and the work is guaranteed for a year.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Do not paint over silicone
- Cone off fresh joints until they’re ready
- Use furniture pads near skirting
- Look at floor joints each spring
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.
Landlord and commercial work in St Mary's
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
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.
How we quote for floor joint sealing
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- The old material and how stubborn it is
- The number and length of the joints
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
When you contact us, these details help:
- What’s wrong with the joints now
- The rough size of the job
- Any previous sealing or DIY work
- Photos by email, if that is easy
Every job is quoted individually, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details and send photos if you have them.
St Mary's: your questions answered
Is St Mary's within the area you cover?
Yes, St Mary's is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on floor joint sealing in St Mary's?
All our work, in St Mary's and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you reseal concrete floor joints in an industrial unit?
Yes. We clean out the joints and reseal them with a product suited to the floor. Tell us what runs over the floor when you ask for a quote.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can you add a movement joint to a tiled floor?
In many cases, yes. We replace the grout along a suitable line with flexible sealant in a matching colour. Loose or cracked tiles need a tiler first.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
When can I walk on the floor?
We will tell you before we leave. That depends on the product, and walking on it usually comes before mopping or wheeled traffic.
When something else is needed
In fairness, there are a few things sealant will not fix:
- A tiled floor that needs relaying
- Concrete repairs beyond the joint
- Floors that are uneven or need levelling
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
