Joints and finishes in New Cross homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
For landlords with property near New Cross station, gaps at skirtings and thresholds are worth sealing between tenancies. New Cross is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How we handle floor joint sealing in New Cross
Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors in a colour to suit. Typical jobs include rigid edge joints in tiled floors and cracked grout where a tiled floor needs a movement joint, across tiled floors, thresholds and commercial floors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.
Each job carries a 12-month guarantee, whatever its size.

How the job changes by surface
Commercial floors
Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.
Skirting boards
If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.
How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most rooms, longer for large commercial floors, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We look at the gap and the floor type and agree the right sealant.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Don’t fill floor joints with caulk where they move or get wet
- Walk round the room once a year and look at the edges
- Have a cracking tiled floor checked before tiles break
- Lift furniture rather than dragging it across joints
Have a look at the joints once the heating season is over. If anything has opened, it’s easy to reseal early on.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the surface smoother.
When something else is needed
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Subfloor problems that need a flooring contractor
- Water getting under the tiles from elsewhere
- Structural movement or subsidence
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

New Cross: your questions answered
I let a flat near New Cross station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is parking a problem for a job in New Cross?
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.
Why does the gap under my skirting keep coming back?
Timber floors and skirting shrink and swell through the year. We close it with a flexible sealant that moves with the floor.
Can you use decorators’ caulk instead?
Caulk can’t cope with movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Do you need floor joint sealing in New Cross?
Some floors were never given a perimeter gap or movement joint. It pushes against the walls and skirting as it expands, and the sealant or grout breaks.
Common reasons people contact us include:
- Failed joint filler in concrete floors
- Grout used at the floor edge instead of sealant
- Dirt and water collecting in open floor joints
- Caulk that has cracked where the floor moves
If you look after a building such as Myatt Garden Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.
