DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
About our new build mastic in Kilmartin
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you are dealing with cracks appearing as a new home settles and plot mastic for developers ahead of handover, we can help, whatever the surface.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Every job comes with our one-year guarantee, wherever you are in Argyll and Bute.

What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. Outdoor work around Kilmartin 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.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- For indoor joints, keep the area dry beforehand if you can

- Leaking shower tray seals in a new home

- Joints pulling apart as timber shrinks
- Messy sealant that spoils new finishes

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Wait for the cure time before using a resealed shower
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

Why act early in Kilmartin
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. 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 the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
