How we handle remedial sealant in Cotman's Ash
In Cotman's Ash, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you’re dealing with black mould underneath the bead and movement joints that have split or pulled away, we can help, on shrunken worktop sealant, botched or over-sealed joints and expansion joints alike.
Homes around Cotman's Ash are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
All our work is covered by our one-year guarantee, wherever you are in Kent.

Can you strip sealant from an acrylic tray safely?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before we start.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you work for landlords and businesses?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
Can you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning before resealing.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before we reseal.
Cotman's Ash homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Schools such as Kemsing Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Kemsing station? Then a joint that keeps failing is best fixed properly while the property is empty.

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Where a wall is exposed, as many are in small places like Cotman's Ash, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Do you need remedial sealant in Cotman's Ash?
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
The most common problems we see are:
- Over-sealed joints coming away
- Smears and lumps from a botched reseal
- Sealant peeling off a dusty or damp surface
- Movement joints that have split or pulled away
In the older streets around Church of Saint Mary the Virgin, walls and floors in older homes can move, and sealant and grout show it first.

- Whether all the old sealant comes out first
- Who turns up on the day
