Common questions in Thorney Island
Do you cover Thorney Island for floor joint sealing?
Yes. We work across London and the South East, and Thorney Island is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Southbourne station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
My floor grout keeps cracking in a line. Can you help?
Often, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.
When can I walk on the floor?
We will tell you before we leave. It depends on the sealant, and light foot traffic is usually fine before wet cleaning or wheels.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can new sealant go over the old?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you seal kitchen plinths to the floor?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone in a colour to suit.
Floor joint sealing for homes and businesses in Thorney Island
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 using a product that suits the floor. Typical jobs include failed joint filler in concrete floors and skirting that has pulled away from the floor, across tiled floors, concrete floor joints and commercial floors.
For a small place like Thorney Island, the journey and access are planned in advance, and the work itself is the same as on any site.

New homes and floors in Thorney Island
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. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as Thorney Island Community Primary School, entrance and corridor floor joints take a lot of traffic. Community buildings like The Parish Church of St Nicholas are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Letting a property close to Southbourne station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

Surface by surface
Thresholds
Two different floors meeting at a threshold move differently. A flexible sealant bridges them.
Skirting boards
Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking painted or coloured to match.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Related advice
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Act on grout cracks that run in a straight line
- Mark off resealed joints in warehouses
- Vacuum floor joints regularly to stop grit building up
- Look at floor joints each spring
Follow the cure time before walking on or cleaning the joint. Light foot traffic is generally fine sooner than wet cleaning or wheels, and we will tell you both.
A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.
Why it’s worth doing now in Thorney Island
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job for most homes. Around Thorney Island, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
