Remedial sealant in Upper Halliford
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. We work on expansion joints, leaking tray & enclosure joints and failed movement joints, and the jobs we see most are thick, messy sealant smeared over tiles and leaks that keep coming back after resealing.
For a small place like Upper Halliford, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we are called out for in Upper Halliford
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
People generally contact us after spotting one of these:
- Mould trapped under a layer of silicone
- Worktop sealant that has shrunk and split
- Movement joints that have split or pulled away
- Over-sealed joints coming away
For an older house near a landmark such as Church of St Mary the Virgin, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- The length of the guarantee
- How much experience the applicator has
- How hidden problems are handled
- Whether the sealant suits the joint
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Never seal over old silicone
- Keep bleach and abrasives off the bead
- Ask why a joint failed before redoing it
- Report a tray that rocks or a worktop that lifts
Give the new sealant its full cure time: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.

Advice
Leave it or put it right?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In a small place like Upper Halliford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before any work starts.
