Remedial sealant in Blackmore
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. We work on expansion joints, mouldy bath & shower sealant and failed movement joints, and people most often call us about worktop sealant that has shrunk and split and dark patches showing through the sealant.
Homes around Blackmore are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
We stand behind the work with a 12-month guarantee.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. In a small place like Blackmore, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

Signs you need remedial sealant in Blackmore
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Look out for these signs:
- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
- Torn expansion joints
- Leaks that keep coming back after resealing
For an older house near a landmark such as Church of St Laurence, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
What to look for in a quote
- Who does the work, and how experienced they are
- How the colour is chosen
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
What happens if it’s left?
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. Where a wall is exposed, as many are in small places like Blackmore, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear quote before work begins.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
