About our new build mastic in Belses
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. Common call-outs are for untidy sealant flagged on a snagging list and gaps opening as the house dries out and settles, on plot handovers, kitchens and bathrooms & en suites.
Around smaller Scottish places like Belses, 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Photograph failed sealant before it’s redone
- Put sealant faults on your snagging list early
- Do not seal over failed sealant yourself
- Ventilate bathrooms well, especially in the first year
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
When to call us in Belses
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Signs it’s time to call us include:
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- Gaps between new skirting and floors
For jobs in and around Belses, choosing the right material for each joint is as important as a tidy finish.
