Floor joint sealing in Cotman's Ash, done properly
Across Cotman's Ash, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. We’re often asked to deal with cracked caulk along skirting in bathrooms and kitchens and open joints that fill with dirt, across wet room & bathroom floors, thresholds and skirting boards.
Older homes in small places like Cotman's Ash often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How the job changes by surface
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and keeps dirt out.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Get cracks along tile grout lines looked at early
- Use furniture pads near skirting
- Check the sealant is paintable before decorating
- Mark off resealed joints in warehouses
Don’t paint over silicone. If you plan to paint, we will use a paintable product.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
What we are called out for in Cotman's Ash
A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands.
Signs it’s time to call us include:
- Cracked grout where a tiled floor needs a movement joint
- Threshold joints that have opened or worn
- Failed joint filler in concrete floors
- Cracked caulk along skirting in bathrooms and kitchens
If you look after a church, hall or community building such as Church of Saint Mary the Virgin, joints in its floors, skirtings and thresholds need resealing as they wear.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the length of joint and we leave things clean and tidy.

- We clear the edges of the floor so the joints are easy to reach.
- Old material is removed from the joint.
- We clean and dry the edges of the joint.
- A flexible sealant suited to the floor is applied and smooth it.
- Finally, we check the work and talk you through aftercare.

Floor joint sealing around Cotman's Ash
Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
Managing a site like Kemsing Primary School? Then entrance and corridor floor joints take a lot of traffic. For landlords with property near Kemsing station, gaps at skirtings and thresholds are worth sealing between tenancies.

Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, large or small.
Will I be able to paint over the new joint?
Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone is not made to be painted, so we use it where the joint stays unpainted.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you seal kitchen plinths to the floor?
Yes. The old joint comes out and a flexible silicone replaces it.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Leave it or put it right?
Floor joints left open collect dirt that’s hard to clean out and makes the floor look worn. A neat sealed joint is easier to clean. Where a wall is exposed, as many are in small places like Cotman's Ash, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
