We cover Sidcup for sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

How we handle floor joint sealing in Sidcup
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone because it handles water. We work on skirting boards, thresholds and tiled floors, and the jobs we see most are failed joint filler in concrete floors and perimeter joints in tiled floors filled with grout.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
There’s a 12-month guarantee on every job, large or small.

Questions from Sidcup
Can you help a landlord with a rental near Sidcup station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can parking be tricky for a visit in Sidcup?
Parking in Sidcup, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
When can I walk on the floor?
It depends on the product and the conditions. Before we leave, we tell you when it can be walked on, mopped and driven over.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Can grout be replaced with sealant on a tiled floor?
Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant.
Floor joint sealing around Sidcup
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That is why the skirting and threshold joints need a flexible seal.
Managing a site like Birkbeck Primary School? Then 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 Holy Trinity Church, floor and skirting joints in halls and kitchens wear like any others.

Surface by surface
Wet room and bathroom floors
Floor joints in bathrooms take water every day. They’re sealed with a flexible, anti-fungal silicone to keep water out of the edges.
Commercial floors
Shops, offices, warehouses and units all have floor joints that need sealing. We talk through the traffic and choose a sealant suited to it.
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a morning or an afternoon for most homes in most cases. In a London area like Sidcup, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, the floor type, the gap and the traffic are checked.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
Getting ready for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Common problems we fix in Sidcup
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, showing where a movement joint was needed.
Look out for these signs:
- Grout cracking in a straight line across a floor
- Cracked caulk along skirting in bathrooms and kitchens
- Open gaps along the bottom of skirting boards
- Dirt and water collecting in open floor joints
Letting a property close to Sidcup station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.
Questions to ask before you book
- Whether the sealant suits the joint
- Who turns up on the day
- What preparation is included
- When the joint can take water or movement
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
