Floor joint sealing in Shawbost
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk normally cracks where there’s movement, so we close it with a flexible sealant instead. We work on concrete floor joints, skirting boards and tiled floors, and people most often call us about gaps at thresholds between rooms and gaps opening between the floor and skirting.
Work in a place like Shawbost is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Every job comes with our one-year guarantee.

What we cannot put right
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Leaks from a failed tanking system

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for most rooms, longer for large commercial floors. Outside jobs in Shawbost need a dry day, because sealant won’t bond to a wet joint, 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Mention any tricky access

Questions from Shawbost
What guarantee comes with floor joint sealing in Shawbost?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover Shawbost for floor joint sealing?
Yes, Shawbost is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you quote for more than one area?
Yes. Just list everything you need.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What affects the quote in Shawbost
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Which sealant suits the joint
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Asking for a quote
When you call or email, it’s useful to know:
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking

Why deal with it now?
Left open, concrete joints break down under traffic. Resealing it early protects the edges. 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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Common problems we fix in Shawbost
Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack, and the sealant or grout breaks.
These are the problems we’re asked about most:
- Cracked caulk along skirting in bathrooms and kitchens
- Skirting that has pulled away from the floor
- Gaps at thresholds between rooms
- Grout used at the floor edge instead of sealant
Around Shawbost, as everywhere, floor joint sealing is only as good as the preparation behind it.
Questions to ask before booking
- Which colour the sealant will be
- Which sealant they’ll use, and why
- How the surfaces are prepared before sealing
- The length of the guarantee
How the job changes by surface
Tiled floors
Tiled floors need movement joints at edges and across large areas. Where needed, a line of grout is replaced with flexible sealant in a matching colour.
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
Floor joint sealing in Shawbost: local notes
Floors around Na h-Eileanan Siar run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own 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.
Whether the job is in Shawbost itself or nearby, the right material for each joint matters as much as a neat finish.
