- Caulk or the wrong sealant used in a wet area
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Remedial sealant for homes and businesses in Tarbet
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. Common call-outs are for movement joints that have split or pulled away and sealant applied over old sealant that has lifted, on expansion joints, leaking tray & enclosure joints and mouldy bath & shower sealant.
Being further from a city doesn’t change the work: old material out, joints cleaned and dried, and a fresh, even finish. We just plan the journey and access beforehand.
We stand behind the work with a one-year guarantee.

FAQs for Tarbet
Do you cover smaller places like Tarbet?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for hotels and guest houses in Tarbet?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before any work starts.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
What if resealing will not fix my leak?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.

Rented homes near Arrochar & Tarbet station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

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.
What happens if it’s left?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

What we’re called out for in Tarbet
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Signs it’s time to call us include:
- Gaps opening along the back of the worktop
- A second bead peeling off the first
- Decorators’ caulk around a bath or shower
- Smears and lumps from a botched reseal
If you live in an older home near Ballyhennan Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

- Whether you can choose the colour

The process
At the end, we look at the finished work together. The visit itself usually takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on how much there is to do. Somewhere like Tarbet may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.

What the job involves on each surface
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, then reseal neatly.
