Floor Joint Sealing in Lewiston
We cover Lewiston for sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old material cut out, joints cleaned and sealed neatly.
- Caulk that has cracked where the floor moves
- Worn sealant at door thresholds
- Tiled floors with no room to move
Leave it or put it right?
Not every floor joint takes the same sealant: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. 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.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

About our floor joint sealing in Lewiston
Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. If you’re dealing with concrete floor joints that have broken down and cracked caulk along skirting in bathrooms and kitchens, we can put it right.
Work in a place like Lewiston is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
All our work is covered by a 12-month guarantee, wherever you are in Highland.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most rooms, longer for large commercial floors. Outside jobs in Lewiston need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Advice
Different surfaces, different methods
Commercial floors
In commercial buildings, we can plan floor joint work around opening hours. We can arrange out-of-hours work.
Skirting boards
Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the new sealant bonds.
Landlord and commercial work in Lewiston
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
New homes and floors in Lewiston
Across Highland, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For buildings such as Kilmore Parish Church of Scotland, floor and skirting joints in halls and kitchens wear like any others. Schools such as Glen Urquhart High School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Lewiston: your questions answered
Is Lewiston in your area for floor joint sealing?
Yes. Our work covers the whole of Scotland, and Lewiston is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Is Lewiston within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
When can I walk on the floor?
It depends on the product and the conditions. We give you the times for walking, cleaning and traffic when we finish so you can plan.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will I be able to paint over the new joint?
Where you plan to paint, we do. Silicone in bathrooms and kitchens cannot be painted, so tell us your plans.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Why does the gap under my skirting keep coming back?
Movement from drying timber and settling floors pulls the skirting and floor apart. Rigid fillers split, so we use a flexible sealant.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What affects the quote in Lewiston
We don’t publish a price list. The quote depends on:
- Whether the work is at height
- Any mould that needs treating
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
When you contact us, these details help:
- The rough size of the job
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, email us at info@mrmastic.co.uk.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check skirting joints after the heating season
- Don’t fill floor joints with caulk where they move or get wet
- Ask before painting over a sealed joint
- Keep dirt out of the joints
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant.
Small gaps are quick to seal. Left alone, they collect dirt and widen over time.
