Floor joint sealing in Selham, done properly
Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints using a product that suits the floor. Typical jobs include skirting caulk that keeps splitting and gaps at thresholds between rooms, on thresholds, concrete floor joints and wet room & bathroom floors.
Around Selham, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Why it’s worth doing now in Selham
Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Around Selham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?
- A sealant colour to suit the surroundings
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- We agree the colour with you first
The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most rooms, longer for large commercial floors. In a small place like Selham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive

- Any access issues, like height or stairs

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common problems we fix in Selham
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits so the gap reappears.
These are the problems we are asked about most:
- Open joints that fill with dirt
- Grout cracking in a straight line across a floor
- Skirting caulk that keeps splitting
- Rigid edge joints in tiled floors
Community buildings like Church of St James are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
Before booking anyone
- Is the old sealant removed completely?
- How the colour is chosen
- What happens if the job turns out different
- The length of the guarantee
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Avoid caulk in bathrooms and kitchens
- Do not slide heavy items over sealed joints
- Act on grout cracks that run in a straight line
- Check the sealant is paintable before decorating
Keep off the joint for the time we give you. Feet are usually fine before mopping or wheeled traffic, and we’ll tell you both.
A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.

Different surfaces, different methods
Tiled floors
The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. We rake out any grout there and reseal.
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. They’re resealed with a flexible, water-resistant sealant.
New homes and floors in Selham
Across West Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
