External Sealant Works in Dover, Kent
External joints have the hardest job of all – coping with driving rain, temperature swings and constant building movement while keeping water out of the structure. That calls for the right sealant, correctly specified and properly applied.
At JH Sealants, we carry out external sealant works for domestic, commercial and contract clients across Dover, Folkestone, Canterbury, Deal, Ashford and the wider East Kent area, using the appropriate grade of mastic for each substrate and finishing every joint to a clean, durable, weather-tight standard.
No job too big or small.

Windows & Doors
Perimeter seals around windows and doors are a building's first line of defence against water ingress and draughts. We seal new installations and re-seal failed joints on existing ones, applying a neat, weatherproof bead that keeps moisture and cold air out and protects the reveal and frame behind it.
Glass to Glass
Glass-to-glass joints, such as those in glazed screens, balustrades and structural glazing, demand a precise, clean finish and the right sealant for a bond that's both strong and clear. We apply these specialist joints neatly and accurately for a discreet, professional result that performs as it should.
Expansion Joints
Buildings move, and expansion joints are designed to absorb that movement without cracking. We apply flexible, movement-accommodating sealants to expansion joints in a range of structures, sized and tooled so the joint flexes and stays watertight through the building's natural expansion and contraction.
Specialised 2-Part Sealant
Two-part sealants that cure to a tougher, more resilient finish than standard single-part products - often specified for demanding structural, industrial or high-movement joints. We mix and apply 2-part sealants to manufacturer specification, delivering the performance these more exacting jobs require.
Concrete Joints
Joints in concrete - whether in structural elements, floors, panels or paving — need a durable seal that stands up to load, weather and movement. We prepare and seal concrete joints with hard-wearing sealants suited to the exposure, protecting against water penetration and the damage that follows once it gets in.
