How we handle floor joint sealing in Tonwell
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. We’re often asked to deal with grout cracking in a straight line across a floor and open joints around bathroom floor edges, on concrete floor joints, thresholds and commercial floors.
Older homes in small places like Tonwell often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Tonwell, 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.

- We apply a flexible sealant suited to the floor.
- We check the joints and explain the aftercare.

Related advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re 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 the job involves on each surface
Concrete floor joints
We clean concrete joints out thoroughly before sealing first. We fit backing where needed.
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Avoid sloshing water against skirting
- Ask before painting over a sealed joint
- Lift furniture rather than dragging it across joints
- Walk round the room once a year and look at the edges
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Why it’s worth doing now in Tonwell
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Older cottages and farmhouses around Tonwell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
