Floor joint sealing in Longstone, done properly
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 with a sealant suited to the movement and traffic. If you have caulk that has cracked where the floor moves and skirting that has pulled away from the floor, we can put it right, whatever the surface.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. Those joints, and plot mastic for developers, are part of the work we cover in Longstone.
Big or small, it’s backed by our one-year guarantee.

Questions from Longstone
Can you do floor joint sealing in Longstone?
Yes, Longstone is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you work for landlords with property near Kingsknowe station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can you seal where the floor meets the bath panel?
Yes. The old joint comes out and a flexible silicone replaces it in a colour to suit.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you use decorators’ caulk instead?
Caulk is fine for dry joints that do not move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
How much does floor joint sealing cost in Longstone?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

- Subfloor problems that need a flooring contractor
- Cracked or broken concrete slabs
- Loose, hollow or cracked tiles, which need a tiler
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Why it’s worth doing now in Longstone
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant stretches instead. For landlords in Longstone, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Instead of a standard rate, 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.

Do you need floor joint sealing in Longstone?
Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and can reach the subfloor.
Any of these means the joints need attention:
- Grout used at the floor edge instead of sealant
- Gaps at thresholds between rooms
- Skirting that has pulled away from the floor
- Tiled floors with no room to move
If you let a flat or house near Kingsknowe station, gaps at skirtings and thresholds are worth sealing between tenancies.
What your quote should include
- Whether all the old sealant comes out first
- Which colour the sealant will be
- How hidden problems are handled
- How long the guarantee is
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on the length of joint, and the area is left clean. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Longstone, tell us the floor, how the door entry system works and where we can park nearby.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- The sealant goes in, chosen for the floor and coloured to suit it.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Preparing for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
Ask for a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.

New homes and floors in Longstone
Floors around Edinburgh 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. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
For site and facilities teams at buildings such as Merchiston Castle School, entrance and corridor floor joints take a lot of traffic.

Different surfaces, different methods
Skirting boards
Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing so the bead sits on a clean surface.
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it if it’s in the right place.
