Floor & skirting joints in Wilmington, East Sussex
Problem with your floor joints in Wilmington? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Worn sealant at door thresholds
- Caulk that has cracked where the floor moves
- Open joints that fill with dirt
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use a well-wrung mop rather than flooding the floor
- Mark off resealed joints in warehouses
- Check skirting joints after the heating season
- Keep dirt out of the joints
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Floor joint sealing in Wilmington, done properly
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out and stops dirt collecting. We work on concrete floor joints, thresholds and skirting boards, and common reasons people get in touch are open gaps along the bottom of skirting boards and open joints that fill with dirt.
In a village or hamlet like Wilmington, 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.
Every job comes with a 12-month guarantee.

Can I do it myself?
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 does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, 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.
What affects the cost of floor joint sealing
For a quick quote, just ask. What matters most is:
- Any mould that needs treating
- The product the joint needs
- The old material and how stubborn it is
- How many areas need sealing
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

- The rough size of the job

What we are called out for in Wilmington
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting and anything rigid cracks.
Any of these means the joints need attention:
- Gaps opening between the floor and skirting
- Gaps at thresholds between rooms
- Skirting caulk that keeps splitting
- Failed seals where bathroom floors meet baths and panels
Letting a property close to Berwick (Sussex) station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Different surfaces, different methods
Skirting boards
Skirting-to-floor joints are a regular job for us. The old caulk is removed first.
Thresholds
Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere as small as Wilmington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- We apply a flexible sealant suited to the floor.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Yes. Each job is guaranteed for twelve months.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Do you work on commercial floors?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Why act early in Wilmington
An open concrete floor joint gets wider every time something heavy crosses it. Resealing it early protects the edges. Around Wilmington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
