About our new build mastic in Duntocher
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on skirting & floors, plot handovers and show homes, and common reasons people get in touch are cracks appearing as a new home settles and untidy sealant flagged on a snagging list.
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.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
New build mastic around Duntocher
Duntocher is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Duntocher is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
In and around Duntocher, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Kilpatrick station, the sealant around baths, showers and frames is worth checking in the first year or two.

Is Duntocher in your area for new build mastic?

Do you work for landlords with property near Kilpatrick station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
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 that we can handle for you.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated photos
- Open a window or run the fan after bathing
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

You do not need to know the technical terms. It helps if you can tell us:
- Roughly how big the job is

The job normally takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go.

- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the size of the job, 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, so you know where you stand.
