Cut Out & Reseal Services in Dover, Kent
Old sealant doesn’t last forever. Over time it lifts, cracks, turns black with mould or discolours – and once the seal fails, water gets into the joints behind it.
Our cut out and reseal service removes the old, failed silicone completely and replaces it with a fresh, clean, watertight bead.
At JH Sealants, we carry out cut out and reseal work for domestic, commercial and contract clients across Dover, Folkestone, Canterbury, Deal, Ashford and the wider East Kent area, with every joint finished by an NVQ Level 2 qualified tradesman.
No job too big or small.

Bathrooms & Wet Rooms
A failed seal is where leaks and damp start. We strip out the old silicone around baths, showers, basins, trays and screens, clean and prepare the surface properly, then reapply a fresh, mould-resistant bead - tooled to a smooth, professional finish and colour-matched to your tiling if needed.
Mouldy Sealant
Black, mouldy sealant isn't just unsightly - it's a sign the seal has broken down and moisture is getting in. Cleaning rarely fixes it for long once mould has taken hold beneath the surface. We remove the affected sealant completely and reapply a fresh, mould-resistant silicone for a clean finish that stays looking right.
Kitchens
Around worktops, upstands, splashbacks and sinks, sealant that's pulled away or gone mouldy lets water reach your units and cabinetry. We remove the failed bead entirely, clean back the joint and reseal with a hygienic, watertight finish that protects the kitchen and looks sharp again.
Failed or Discoloured Sealant
Sealant that's lifting, peeling, shrinking or gone yellow has reached the end of its life and no longer does its job, inviting moisture into joints and cracks. We take it back to a clean joint and reseal to a crisp, consistent line - restoring both the appearance and the watertight seal.
External Remedial Works
Perished or split external sealant needs dealing with before water gets into the structure. We cut out failed weatherproofing around windows, doors, cladding and expansion joints and reseal with the correct grade of mastic for the substrate, restoring a durable, weather-tight barrier.
