Remedial Sealant in St David's
We cover St David's for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Mould trapped under a layer of silicone
- Repeat leaks from the same joint
- Products that weren’t meant for the joint
What we’re called out for in St David's
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
The problems people usually mention when they call include:
- Decorators’ caulk around a bath or shower
- Over-sealed joints coming away
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
For jobs in and around St David's, choosing the right material for each joint is as important as a tidy finish.

Remedial sealant in St David's, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. If you’re dealing with products that weren’t meant for the joint and mould trapped under a layer of silicone, we can put it right, on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant alike.
For a place like St David's, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. The journey and access are simply planned in advance.
All our work comes with our 12-month guarantee.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Air the bathroom so the sealant can dry
- Look for stains below bathrooms now and then
- Never seal over old silicone
- Clean sealant with mild products only
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
What the job involves on each surface
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned.
How we quote for remedial sealant
Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
- Any mould that needs treating
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote

What remedial sealant looks like in St David's
Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.
Around St David's, as everywhere, remedial sealant is only as good as the preparation behind it.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it.

Somewhere like St David's may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
