How we handle floor joint sealing in Hamsey
Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors so the joint stays neat. If you’re dealing with grout used at the floor edge instead of sealant and grout cracking in a straight line across a floor, we can help, on commercial floors, thresholds and wet room & bathroom floors alike.
Work in a small place like Hamsey just needs the journey and access planning, and once on site, the job is the same as anywhere.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Floor joint sealing in Hamsey: local notes
Across East 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.
If you look after a building such as Hamsey Community Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. If you look after a church, hall or community building such as The Parish Church of St Peter, joints in its floors, skirtings and thresholds need resealing as they wear.

Why it’s worth doing now in Hamsey
Leaving skirting gaps until the next decorating job lets dirt and draughts in. Sealing them now is a short job for most homes. Around Hamsey, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

How the job changes by surface
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is generally better.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Bouncy or failing floorboards
- Loose, hollow or cracked tiles, which need a tiler
- Large cracks that need a surveyor

Hamsey: your questions answered
Can you do floor joint sealing in Hamsey?
Yes. We work across London and the South East, and Hamsey is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is Hamsey within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours, depending on the length of joint. We will give you a better idea when we quote.
What causes gaps between the floor and skirting?
It’s normally the floor moving: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible bead keeps up with the movement.
Where do you work from?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you seal warehouse floor joints?
Yes, including warehouses, units, shops and offices. Work can be planned around your hours with out-of-hours work where needed.
Can you use decorators’ caulk instead?
Caulk is fine for dry joints that don’t move, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
What affects the cost of floor joint sealing
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- When we can work, for business premises
- The amount of work
- How many rooms, windows or areas are involved
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What we need to know
To make quoting easier, please include:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand.
Also in Hamsey
Do you need floor joint sealing in Hamsey?
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, where a flexible joint should have been.
If you can see any of these, it’s time to have the joints looked at:
- Open gaps along the bottom of skirting boards
- Open joints that fill with dirt
- Tiled floors with no room to move
- Threshold joints that have opened or worn
Rented homes near Cooksbridge station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.
What your quote should include
- Which colour the sealant will be
- Is VAT in the price?
- The length of the guarantee
- What happens if they find a problem under the old sealant
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep heavy wheels off new concrete joints until cured
- Check the sealant is paintable before decorating
- Keep caulk for dry, still joints only
- Have a cracking tiled floor checked before tiles break
Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed while it cures.
Small gaps are quick to seal. Left alone, they collect dirt and widen and are harder to clean out.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning or an afternoon for most homes, and the area is left clean. In a small place like Hamsey, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- The sealant goes in, chosen for the floor and coloured to suit it.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
