- Dirt and water collecting in open floor joints
- Perimeter joints in tiled floors filled with grout
- Skirting caulk that keeps splitting
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Lift furniture rather than dragging it across joints
- Vacuum floor joints regularly to stop grit building up
- Do not fill floor joints with caulk where they move or get wet
- Mark off resealed joints in warehouses
Follow the cure time before walking on or cleaning the joint. Feet are generally fine before mopping or wheeled traffic, and we will tell you both.
Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges and the floor safer.
How we handle floor joint sealing in Northchurch
Painted skirting can be sealed with a flexible product that can be painted over. In wet areas we’d normally use silicone because it handles water. If you have skirting that has pulled away from the floor and rigid edge joints in tiled floors, we can put it right.
In and around Northchurch, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Do you need floor joint sealing in Northchurch?
When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, where a flexible joint should have been.
Keep an eye out for these signs:
- Open joints around bathroom floor edges
- Open gaps along the bottom of skirting boards
- Threshold joints that have opened or worn
- Grout used at the floor edge instead of sealant
If you look after a church, hall or community building such as Church of Saint Mary, joints in its floors, skirtings and thresholds need resealing as they wear.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you work on commercial floors?
