How we handle new build mastic in Thankerton
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Typical jobs include worktop and upstand sealant coming away and leaking shower tray seals in a new home, on kitchens, skirting & floors and plot handovers.
Around smaller Scottish places like Thankerton, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
New build mastic in Thankerton: local notes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Thankerton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Carstairs station, it’s worth checking the sealant early, while snags are still fresh.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home, including the tidy-up. Outside jobs in Thankerton need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Mention any tricky access
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Why act early in Thankerton
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In an older home around Thankerton, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep water off fresh sealant until it has cured
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
What we cannot put right
A few problems are outside what sealant work can do:
- Cracked trays, tiles or worktops
- A tray or bath that isn’t properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.
