Floor joint sealing in Scrabster, done properly
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on wet room & bathroom floors, thresholds and commercial floors, and common reasons people get in touch are caulk that has cracked where the floor moves and chipped and open joints in warehouse floors.
Around smaller Scottish places like Scrabster, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for Scrabster
Do you cover Scrabster for floor joint sealing?
Yes, Scrabster is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Thurso station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Do you offer different sealant colours?
Normally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before work begins.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Why not just use caulk?
Caulk works on still, dry joints, but it splits where the joint moves or gets wet. For most floor joints, we use a flexible sealant.
When to call us in Scrabster
A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands and joints fail.
People generally contact us after spotting something like this:
- Gaps at thresholds between rooms
- Cracked grout where a tiled floor needs a movement joint
- Grout used at the floor edge instead of sealant
- Gaps opening between the floor and skirting
If you look after a building such as Thurso High School, floor and threshold joints in busy corridors wear quickly and are best resealed early.
Before booking anyone
- How much experience the applicator has
- Whether they seal over old material or remove it
- What guarantee comes with the work
- Whether they’re fully insured
Leave it or put it right?
Left open, concrete joints break down under traffic. Resealing it early protects the edges and keeps the damage down. In an older home around Scrabster, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Why us?
- Quality sealants from Arbo and Everbuild
- Anti-fungal silicone where joints get wet
- A choice of colours where the product allows
- We’re fully insured

How it works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for most rooms, longer for large commercial floors, including the tidy-up. For a place like Scrabster, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- On commercial sites, let us know about site rules

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Aftercare tips
So the new joints stay in good condition:
- Keep dirt out of the joints
- Act on grout cracks that run in a straight line
- Do not paint over silicone
- Use furniture pads near skirting
Do not paint over silicone. If you plan to paint, we’ll use a paintable product.
Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact and the surface smoother.
Surface by surface
Wet room and bathroom floors
Mop water gets into any open joint at the edge of a bathroom floor. A flexible seal stops water running into the gap.
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.
What affects the cost of floor joint sealing
The quote reflects the job in front of us. We look at:
- The amount of work
- Which sealant suits the joint
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- The address or postcode of the job
- Roughly how big the job is
- If someone has resealed it before
- Whether it’s a home or a business
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.
Floor joint sealing in Scrabster: local notes
Across Highland, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. That’s 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.
If you let a flat or house near Thurso station, gaps at skirtings and thresholds are worth sealing between tenancies.
