About our remedial sealant in St Fillans
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We are often asked to deal with mould trapped under a layer of silicone and wide, uneven beads that look worse than the old ones, on expansion joints, failed movement joints and mouldy bath & shower sealant.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
We stand behind the work with a 12-month guarantee.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Surface by surface
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 before backing and resealing.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.

Bathrooms and kitchens in St Fillans
In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in. 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 does not dry out.
Around St Fillans, as everywhere, remedial sealant is only as good as the preparation behind it. Homes close to Church Of The Holy Spirit include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Related advice
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Air the bathroom so the sealant can dry
- Check ceilings under showers for marks
- Never seal over old silicone
- Ask why a joint failed before redoing it
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.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
