Floor joint sealing around Falconwood
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the 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. That’s why the skirting and threshold joints need a flexible seal.
Letting a property close to Welling station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a building such as Bishop Ridley Church of England VA Primary School, entrance and corridor floor joints take a lot of traffic.

Floor joint sealing in Falconwood
In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant. If you are dealing with tiled floors with no room to move and floor edges that trap water and grime, we can help, on tiled floors, skirting boards and commercial floors alike.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement, in Falconwood as anywhere.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What the job involves on each surface
Skirting boards
On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is normally better.
Wet room and bathroom floors
Wet room floors rely on sound joints at the walls. We reseal it with a flexible silicone suited to wet areas.
FAQs for Falconwood
Do you cover Falconwood for floor joint sealing?

I let a flat near Welling station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Can I add another job to the visit?

Can you add a movement joint to a tiled floor?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Is there any odour?

How the visit works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for most rooms, longer for large commercial floors from start to finish. 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.
- Old caulk, grout or sealant is removed from the joint.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Clear the area around the work
Ask for a quote
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Related advice
Do you need floor joint sealing in Falconwood?
Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away.
Most people get in touch when they notice something like this:
- Floor edges that trap water and grime
- Open joints around bathroom floor edges
- Tiled floors with no room to move
- Failed joint filler in concrete floors
Falconwood is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why it’s worth doing now in Falconwood
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Falconwood.
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 we need extra access for height. Your quote takes all of that into account.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep floor cleaning water to a minimum at the edges
- Walk round the room once a year and look at the edges
- Keep caulk for dry, still joints only
- Sweep along the edges of the floor
Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead 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.
