DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
Floor joint sealing in Duckett's Green
Across Duckett's Green, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, because the right sealant depends on both. Typical jobs include perimeter joints in tiled floors filled with grout and gaps opening between the floor and skirting, across wet room & bathroom floors, tiled floors and concrete floor joints.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
Our work is backed for twelve months, in Duckett's Green and everywhere else we cover.

Floor joint sealing around Duckett's Green
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and 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 church, hall or community building such as Christ Church, joints in its floors, skirtings and thresholds need resealing as they wear. Rented homes near Hornsey station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Your questions about floor joint sealing in Duckett's Green
Can parking be tricky for a visit in Duckett's Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you cover Duckett's Green for floor joint sealing?
Yes, Duckett's Green is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Will I be able to paint over the new joint?
For painted skirting, we use a flexible product that can be painted. Silicone is not made to be painted, so we use it where the joint stays unpainted.
Can you reseal concrete floor joints in an industrial unit?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor when you ask for a quote.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
What does floor joint sealing cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.

What happens if it’s left?
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant moves with the floor, so the joint stays closed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Duckett's Green, the repair is bigger than the sealant job would have been.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before work begins. The work generally takes a few hours for most rooms, longer for large commercial floors. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we check the joint and the floor and agree which sealant suits it.
- We take out any old caulk, sealant or grout along the line.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Before we arrive
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Signs you need floor joint sealing in Duckett's Green
Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water, which is why so many skirting joints look broken.
Common reasons people contact us include:
- Skirting that has pulled away from the floor
- Cracked caulk along skirting in bathrooms and kitchens
- Failed joint filler in concrete floors
- Open joints around bathroom floor edges
If you look after a building such as St John Vianney RC Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

- Who turns up on the day
- Whether VAT is included
- What happens if they find a problem under the old sealant

How the job changes by surface
Commercial floors
Floor joint work in businesses can be planned around your hours. We can arrange out-of-hours work where it’s needed.
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Housing providers, facilities teams and property managers book us too in Duckett's Green and across Greater London. Several sites can be quoted together, and we are fully insured.
Aftercare tips
A little care helps the new joints last. We recommend:
- Get cracks along tile grout lines looked at early
- Check the sealant is paintable before decorating
- Walk round the room once a year and look at the edges
- Lift furniture rather than dragging it across joints
Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.
Small gaps are quick to seal. Left alone, they collect dirt and widen.
