Floor Joint Sealing in Sepham Heath
Floor joints in Sepham Heath need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

- Gaps opening between the floor and skirting
Floor joint sealing in Sepham Heath, done properly
Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints with a sealant suited to the movement and traffic. We work on commercial floors, concrete floor joints and wet room & bathroom floors, and the jobs we see most are floor edges that trap water and grime and worn sealant at door thresholds.
Older homes in small places like Sepham Heath often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job.

DIY versus a professional finish
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 are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Loose, hollow or cracked tiles, which need a tiler
- Leaks from a failed tanking system
- Cracked or broken concrete slabs
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Commercial floors
- Tiled floors
- Skirting boards
- Concrete floor joints
- Wet room & bathroom floors
- Thresholds
Why it’s worth doing now in Sepham Heath
Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. Where a wall is exposed, as many are in small places like Sepham Heath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Check skirting joints after the heating season
- Keep dirt out of the joints
- Keep floor cleaning water to a minimum at the edges
- Don’t paint over silicone
Avoid flooding the floor when you clean. Less water at the edges helps the joints last.
Open skirting gaps let in draughts, dust and sometimes insects. Sealing it early keeps the room cleaner and the edges sound.
What we are called out for in Sepham Heath
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.
If you can see any of these, it’s time to have the joints looked at:
- Grout cracking in a straight line across a floor
- Worn sealant at door thresholds
- Floor edges that trap water and grime
- Failed seals where bathroom floors meet baths and panels
Community buildings like Otford Lane Mission Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
Questions to ask before booking

Tiled floors

Wet room and bathroom floors
Wet room floors rely on sound joints at the walls. It’s resealed with a sanitary silicone.
