Floor Joint Sealing in Horsham
Problem with your floor joints in Horsham? We cut out the old, prepare the joints and apply the right sealant.
- Floor edges that trap water and grime
- Tiled floors with no room to move
- Gaps between floors and kitchen plinths
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we handle floor joint sealing in Horsham
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. We work on concrete floor joints, skirting boards and thresholds, and common reasons people get in touch are gaps opening between the floor and skirting and cracked caulk along skirting in bathrooms and kitchens.
A place the size of Horsham has new developments as well as older streets. Snags in sealant and floor joints often show in a new home’s first year or two, as a new house dries out and settles.
All our work is covered by our 12-month guarantee.

When to call us in Horsham
An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean.
The most common problems we see are:
- Gaps between floors and kitchen plinths
- Cracked caulk along skirting in bathrooms and kitchens
- Skirting that has pulled away from the floor
- Cracked grout where a tiled floor needs a movement joint
For buildings such as Hope Chapel, joints in its floors, skirtings and thresholds need resealing as they wear.
What your quote should include
- What preparation is included
- When the joint can take water or movement
- Which sealant they’ll use, and why
- What insurance they hold
When it isn’t the sealant
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Loose, hollow or cracked tiles, which need a tiler
- Cracked or broken concrete slabs
- Water getting under the tiles from elsewhere
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Different surfaces, different methods
Wet room and bathroom floors
Mop water gets into any open joint at the edge of a bathroom floor. A flexible seal stops water running into the gap.
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product and tool it flush.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Use furniture pads near skirting
- Keep floor cleaning water to a minimum at the edges
- Check skirting joints after the heating season
- Vacuum floor joints regularly to stop grit building up
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead before it has fully cured.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner.
