Haroldswick questions
Is Haroldswick within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on floor joint sealing in Haroldswick?
All our work, in Haroldswick and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you add a movement joint to a tiled floor?
Normally, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.
What causes gaps between the floor and skirting?
Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.
Do you use a paintable sealant?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone isn’t made to be painted, so we use it where the joint stays unpainted.
Floor joint sealing in Haroldswick
Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints. If you have failed seals where bathroom floors meet baths and panels and gaps opening between the floor and skirting, we can put it right, on commercial floors, wet room & bathroom floors and concrete floor joints alike.
For a place like Haroldswick, the journey and access are planned in advance. Inside work goes ahead in any weather; outside mastic needs a dry day.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Floor joint sealing in Haroldswick: local notes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. Island jobs need planning around ferries and the weather, so the more notice, the better.
If you look after a church, hall or community building such as St John's Church, floor and skirting joints in halls and kitchens wear like any others.

- Caulk that has cracked where the floor moves
- Gaps at thresholds between rooms
- Gaps opening between the floor and skirting
Around Haroldswick, as everywhere, floor joint sealing is only as good as the preparation behind it.

We also work for property managers and facilities teams in Haroldswick and across the Shetland Islands. Several sites can go on one quote, and we’re fully insured for the work.
Letting agents and landlords in Haroldswick can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Why act early in Haroldswick
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job. 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.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
What you get with us
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over
- A sealant colour to suit the surroundings
- One-year guarantee on every job
What else we do in Haroldswick
How to look after the new joints
After the cure time, these simple habits help:
- Keep floor cleaning water to a minimum at the edges
- Keep heavy wheels off new concrete joints until cured
- Sweep along the edges of the floor
- Don’t fill floor joints with caulk where they move or get wet
Follow the cure time before walking on or cleaning the joint. Feet are generally fine before mopping or wheeled traffic, and we’ll tell you both.
Sealing a gap while it’s small is a quick job. Left alone, they collect dirt and widen.
How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on the length of joint for a typical job. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
Before we arrive
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work

Advice
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from a failed tanking system
- Bouncy or failing floorboards
- A tiled floor that needs relaying
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
