Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Remedial sealant in Cumnock
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. If you are dealing with worktop sealant that has shrunk and split and dark patches showing through the sealant, we can put it right, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints alike.
In and around a place like Cumnock, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
For anyone letting property in or around Cumnock, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a typical bath or shower, longer where several layers have been applied. Outdoor work around Cumnock depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Before we arrive
- Let us know about parking restrictions
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Why act early in Cumnock
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Around Cumnock, water from a failed joint in an older stone home can soak into timber and plaster.

What the job involves on each surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Mouldy bath & shower sealant
Repeat mould normally points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
What we’re called out for in Cumnock
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Signs it’s time to call us include:
- Over-sealed joints coming away
- A shower that leaks however often it’s resealed
- Sealant peeling off a dusty or damp surface
- Products that weren’t meant for the joint
For landlords with property near Auchinleck station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
