Problem with your new-build sealant joints in East Helmsdale? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.

New build mastic in East Helmsdale, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you’re dealing with sealant that never bonded to the surface and leaking shower tray seals in a new home, we can help.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

New homes and floors in East Helmsdale
East Helmsdale is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

What else we do in East Helmsdale
Landlord and commercial work in East Helmsdale
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Keeping the joints in good condition
Looking after new joints is easy:
- Keep water off fresh sealant until it has cured
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Don’t seal over failed sealant yourself
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:
- A tray or bath that is not properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
