Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Floor joint sealing in Blackdog, done properly
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant. We work on skirting boards, wet room & bathroom floors and tiled floors, and the jobs we see most are gaps opening between the floor and skirting and rigid edge joints in tiled floors.
Work in a place like Blackdog is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
There’s a 12-month guarantee on every job.

When to call us in Blackdog
When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, showing where a movement joint was needed.
People generally contact us after spotting one of these:
- Rigid edge joints in tiled floors
- Gaps at thresholds between rooms
- Skirting caulk that keeps splitting
- Open joints around bathroom floor edges
Letting a property close to Dyce station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Why it’s worth doing now in Blackdog
The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Every job guaranteed for a year
- Old sealant always removed completely
- Approved under the ARBOMaster scheme
- A choice of colours where the product allows

Your questions about floor joint sealing in Blackdog
Is Blackdog in your area for floor joint sealing?
Yes. We work across all of Scotland, and Blackdog is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Will you come out to Blackdog?
Yes, Blackdog is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Can grout be replaced with sealant on a tiled floor?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit so the floor can move.
How long does the job take?
It depends on the size of the job, but as a guide it takes a morning or an afternoon for most homes. We will give you a better idea when we quote.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do you work on commercial floors?
Yes. We reseal concrete floor joints in commercial and industrial units. We will talk through the traffic and choose a sealant suited to it.

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, send an email to info@mrmastic.co.uk.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for most rooms, longer for large commercial floors, depending on how much there is to do. Outdoor work around Blackdog depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints

What floor joint sealing looks like in Blackdog
Across Aberdeen, 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Blackdog, as everywhere, floor joint sealing is only as good as the preparation behind it.

What the job involves on each surface
