About our floor joint sealing in Nash
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. If you have floor edges that trap water and grime and perimeter joints in tiled floors filled with grout, we can put it right.
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, in Nash and beyond.
All our work is covered by a 12-month guarantee.

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.
Why deal with it now?
Dirt builds up in open joints. A neat sealed joint is easier to clean. In a flat in Nash, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Do not fill floor joints with caulk where they move or get wet
- Act on grout cracks that run in a straight line
- Sweep along the edges of the floor
- Avoid sloshing water against skirting
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.
Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.
Common questions in Nash
Can parking be tricky for a visit in Nash?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you do floor joint sealing in Nash?
Yes, Nash is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Are you fully insured?
Yes. Full insurance covers our work.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
How long will you be here?
Typically it takes a few hours, depending on the length of joint. Larger jobs naturally take longer, and we will tell you how long to expect.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
What causes gaps between the floor and skirting?
Floors shrink and settle, especially in the first year or two and through the heating season opens the gap. Caulk tends to crack; a flexible sealant does not.
What floor joint sealing looks like in Nash
Much of London’s new housing is flats in larger 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.
As a London address, Nash can be tricky for parking: let us know about parking bays, permits or a driveway. For buildings such as Keston Parish Church, joints in its floors, skirtings and thresholds need resealing as they wear. If you look after a building such as Wickham Common Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.
