What we are called out for in North Dell
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges.
These are the problems we’re asked about most:
- Skirting that has pulled away from the floor
- Cracked grout where a tiled floor needs a movement joint
- Rigid edge joints in tiled floors
- Open joints around bathroom floor edges
In and around North Dell, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.
What your quote should include

- What product goes in the joint
- How the surfaces are prepared before sealing
- The length of the guarantee
Floor joint sealing in North Dell
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints. Typical jobs include failed joint filler in concrete floors and cracked caulk along skirting in bathrooms and kitchens, on concrete floor joints, tiled floors and commercial floors.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

How the job changes by surface
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and keeps dirt out.
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Joints and finishes in North Dell homes
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
For buildings such as Church of Scotland, floor and skirting joints in halls and kitchens wear like any others.

What else we do in North Dell
North Dell: your questions answered
Do you cover North Dell for floor joint sealing?
Yes, North Dell is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
What guarantee comes with floor joint sealing in North Dell?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
My floor grout keeps cracking in a line. Can you help?
Often, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Can you use decorators’ caulk instead?
Caulk cannot cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.
Do you have insurance?
Yes. We are fully insured.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Failed waterproofing under a wet room floor
- Cracked or broken concrete slabs
- Movement too big for a sealant joint
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- Tiled floors
- Thresholds
- Skirting boards
- Commercial floors
- Concrete floor joints
- Wet room & bathroom floors
How we quote for floor joint sealing
The quote reflects the job in front of us. We take into account:
- Whether there’s mould to deal with
- Which sealant suits the joint
- The old material and how stubborn it is
- The size of the job
Doing several joints on one visit normally makes better use of the time than several visits. We will give you a clear quote for the lot.
Asking for a quote
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Why deal with it now?
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. Around North Dell, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
Why us?
- We never seal over old sealant
- Sealant colour chosen to suit
- Homes, businesses and hotels
- White, clear, grey or another colour, product permitting

Aftercare tips
Good habits help new joints last longer. A few tips:
- Sweep along the edges of the floor
- Don’t slide heavy items over sealed joints
- Keep caulk for dry, still joints only
- Walk round the room once a year and look at the edges
Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels, and we’ll tell you both.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
How it works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job normally takes a few hours for most rooms, longer for large commercial floors. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Old caulk, grout or sealant is removed from the joint.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Preparing for the visit
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
