Different surfaces, different methods
Tiled floors

Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
Floor joint sealing in Nuneham Courtenay, done properly
Across Nuneham Courtenay, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, because the right sealant depends on both. We work on tiled floors, thresholds and skirting boards, and people most often call us about failed joint filler in concrete floors and worn sealant at door thresholds.
Somewhere as small as Nuneham Courtenay, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Every job comes with a one-year guarantee, wherever you are in Oxfordshire.

Sealant isn’t the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Tiles that have lifted or broken
- Failed waterproofing under a wet room floor
- Movement too big for a sealant joint

Is caulk good enough for skirting?
Caulk works on still, dry joints, but it cracks where there’s movement or water. We use a flexible sealant for most skirting and floor joints.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you seal kitchen plinths to the floor?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Can you reseal concrete floor joints in an industrial unit?
Yes. Concrete floor joints in warehouses and units are part of our work. We will talk through the traffic and choose a sealant suited to it.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Signs you need floor joint sealing in Nuneham Courtenay
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.
Look out for these signs:
- Grout used at the floor edge instead of sealant
- Caulk that has cracked where the floor moves
- Open joints around bathroom floor edges
- Dirt and water collecting in open floor joints
Letting a property close to Radley station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

Joints and finishes in Nuneham Courtenay homes
Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
If you look after a church, hall or community building such as Church of St Peter, floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as Marsh Baldon Church of England Controlled School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Why deal with it now?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Around Nuneham Courtenay, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Look at floor joints each spring
- Use furniture pads near skirting
- Keep caulk for dry, still joints only
- Mark off resealed joints in warehouses
Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and the edges sound.
