About our remedial sealant in South Dell
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. We work on expansion joints, shrunken worktop sealant and botched or over-sealed joints, and people most often call us about floor or wall movement joints that have failed and mould trapped under a layer of silicone.
Bathrooms in smaller places like South Dell work just as hard as those in the cities. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
Our work is backed for twelve months.

Signs you need remedial sealant in South Dell
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
The most common problems we see are:
- Products that weren’t meant for the joint
- Worktop sealant that has shrunk and split
- Smears and lumps from a botched reseal
- Movement joints that have split or pulled away
For jobs in and around South Dell, choosing the right material for each joint is as important as a tidy finish.

South Dell homes and their sealant
South Dell is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
In and around South Dell, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Advice
Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In an older home around South Dell, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.
Why South Dell clients choose us

For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check ceilings under showers for marks
- Don’t point over movement joints
- Never seal over old silicone
- Check trays and worktops don’t move
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
