- Floor edges that trap water and grime

- Chipped and open joints in warehouse floors
Different surfaces, different methods
Tiled floors
When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint where it suits the floor.
Thresholds
Where a tiled floor meets timber or carpet, the joint takes movement from both sides. We bridge them with a flexible bead.
Floor joint sealing in Kensal Rise, done properly
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone, which is not made to be painted. We are often asked to deal with skirting caulk that keeps splitting and grout used at the floor edge instead of sealant, across concrete floor joints, commercial floors and tiled floors.
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.
Big or small, you get the same one-year guarantee in Kensal Rise and across Greater London.

What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the length of joint. For a job in Kensal Rise, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- The room is cleared along the joints so we can reach them.
- We take out the cracked caulk, grout or old sealant.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and tooled.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

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 doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Subfloor problems that need a flooring contractor
- Loose, hollow or cracked tiles, which need a tiler
- Concrete repairs beyond the joint
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Mark off resealed joints in warehouses
- Have a cracking tiled floor checked before tiles break
- Ask before painting over a sealed joint
- Keep dirt out of the joints
Silicone sealant isn’t made to take paint. If you plan to paint, we’ll use a paintable product.
Small gaps are quick to seal. Ignored, they fill with dirt and open further.
Floor joint sealing around Kensal Rise
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. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
Rented homes near Kensal Rise station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a church, hall or community building such as Church of St John the Evangelist, joints in its floors, skirtings and thresholds need resealing as they wear. As a London address, Kensal Rise can be tricky for parking: let us know about parking bays, permits or a driveway.

Leave it or put it right?
Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant stretches instead, 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 Kensal Rise, the repair is bigger than the sealant job would have been.
