Floor joint sealing in Warnham
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk generally cracks where there’s movement, so we close it with a flexible sealant instead. We work on tiled floors, commercial floors and wet room & bathroom floors, and the jobs we see most are open joints around bathroom floor edges and rigid edge joints in tiled floors.
For a small place like Warnham, the journey and access are planned in advance, and the work itself is the same as on any site.
Every job is covered by a one-year guarantee.

Where is Mr Mastic based?

Can grout be replaced with sealant on a tiled floor?
Often, yes. We replace the grout along a suitable line with flexible sealant coloured to suit. Loose or cracked tiles need a tiler first.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How soon can the floor be mopped?
We give you a cure time for each joint. Feet are normally fine first, then mopping, then heavy wheels, depending on the product.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Keep caulk for dry, still joints only
- Check skirting joints after the heating season
- Keep dirt out of the joints
- Act on grout cracks that run in a straight line
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most rooms, longer for large commercial floors. Somewhere as small as Warnham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied.
- We check the joints and explain the aftercare.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Keep children and pets away from the work area

How the job changes by surface
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product.
Concrete floor joints
Hard wheels break down the edges of open joints. Sealing them supports the edges and keeps dirt out.
What we cannot put right
We will always be straight with you, so here’s what new sealant will not do:
- A tiled floor that needs relaying
- Subfloor problems that need a flooring contractor
- Large cracks that need a surveyor
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Thresholds
- Tiled floors
- Skirting boards
- Commercial floors
- Concrete floor joints
- Wet room & bathroom floors
Why it’s worth doing now in Warnham
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Where a wall is exposed, as many are in small places like Warnham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What floor joint sealing looks like in Warnham
Across West Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
Rented homes near Warnham station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a building such as Warnham CofE Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. If you look after a church, hall or community building such as The Parish Church of St Margaret, joints in its floors, skirtings and thresholds need resealing as they wear.
