About our floor joint sealing in Cootham
Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant. We work on concrete floor joints, skirting boards and thresholds, and people most often call us about open gaps along the bottom of skirting boards and failed seals where bathroom floors meet baths and panels.
In a village or hamlet like Cootham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
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.

Why it’s worth doing now in Cootham
Not every floor joint takes the same sealant: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. Around Cootham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.

How to look after the new joints
To keep the joints looking good and working properly:
- Get cracks along tile grout lines looked at early
- Don’t slide heavy items over sealed joints
- Don’t paint over silicone
- Do not fill floor joints with caulk where they move or get wet
Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
DIY sealant or a professional job?
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 do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

My floor grout keeps cracking in a line. Can you help?

Signs you need floor joint sealing in Cootham
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges.
People normally contact us when they notice something like this:
- Gaps between floors and kitchen plinths
- Dirt and water collecting in open floor joints
- Perimeter joints in tiled floors filled with grout
- Caulk that has cracked where the floor moves
Schools such as Storrington Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
