Floor & skirting joints in Fortis Green, Greater London
Problem with your floor joints in Fortis Green? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Threshold joints that have opened or worn
- Cracked grout where a tiled floor needs a movement joint
- Gaps between floors and kitchen plinths
Floor joint sealing in Fortis Green, done properly
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out. If you have dirt and water collecting in open floor joints and failed seals where bathroom floors meet baths and panels, we can help, whatever the surface.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Look at floor joints each spring
- Mark off resealed joints in warehouses
- Get cracks along tile grout lines looked at early
- Use furniture pads near skirting
Check the joints after the first winter. If anything has opened, it’s easy to reseal before they spread.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we are called out for in Fortis Green
Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean.
Signs it’s time to call us include:
- Cracked caulk along skirting in bathrooms and kitchens
- Open joints around bathroom floor edges
- Grout used at the floor edge instead of sealant
- Concrete floor joints that have broken down
Community buildings like United Reformed Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What floor joint sealing looks like in Fortis Green
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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
Managing a site like Fortismere School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Fortis Green is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

How the job changes by surface
Tiled floors
A crack running along a grout line is often a sign of a missing movement joint. We rake out that line and seal it where it suits the floor.
Thresholds
Thresholds take daily traffic, so the sealant has to be tough as well as flexible and tool it flush.
What happens on the day
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on the length of joint. For a job in Fortis Green, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by checking the floor, the joint and what traffic it takes.
- Any old caulk, grout or sealant is raked or cut out.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
