Floor joint sealing around Duncton
Across West Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.
For buildings such as Church of Holy Trinity, floor and skirting joints in halls and kitchens wear like any others.
Duncton is about 10 miles north-east of Chichester, in West Sussex. Across the GU28 area, we cover floor joint sealing for homes and businesses. Duncton is one of 371 towns and villages in West Sussex where we work for floor joint sealing. We also work in Crawley, about 22 miles from Duncton.

Floor joint sealing in Duncton
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant coloured to suit the grout. We work on concrete floor joints, thresholds and commercial floors, and common reasons people get in touch are chipped and open joints in warehouse floors and worn sealant at door thresholds.
In a village or hamlet like Duncton, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Duncton: your questions answered
Is Duncton in your area for floor joint sealing?
Yes, Duncton is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is floor joint sealing in Duncton guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
When can I walk on the floor?
You’ll get the times before we go. That depends on the product, and walking on it normally comes before mopping or wheeled traffic.
What should I tell you?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How we quote for floor joint sealing
We quote each job individually. These are the things that affect it:
- How easy the joints are to reach
- The number and length of the joints
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
What it costs depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
We do not publish a price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.

Signs you need floor joint sealing in Duncton
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting, and rigid fillers crack.
The problems people normally mention when they call include:
- Cracked caulk along skirting in bathrooms and kitchens
- Tiled floors with no room to move
- Gaps between floors and kitchen plinths
- Floor edges that trap water and grime
For site and facilities teams at buildings such as Duncton CofE Junior School, entrance and corridor floor joints take a lot of traffic.

What the job involves on each surface
Skirting boards
Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the bead sits on a clean surface.
Commercial floors
Floor joint work in businesses can be planned around your hours. Out-of-hours working can be arranged.
DIY sealant or a professional job?
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 does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Leave it or put it right?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead. Older cottages and farmhouses around Duncton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

How to look after the new joints
Looking after new joints is easy:
- Keep dirt out of the joints
- Don’t fill floor joints with caulk where they move or get wet
- Act on grout cracks that run in a straight line
- Use furniture pads near skirting
Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant especially in the first few days.
A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.
