New build mastic for homes and businesses in Letham
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on kitchens, show homes and windows & doors, and people most often call us about new-build shower sealant that has already split and sealant that never bonded to the surface.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
Big or small, you get the same one-year guarantee.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
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.
The process
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots. Outside jobs in Letham need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Get a leaking seal dealt with right away
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you, so raise it early.
