How we handle new build mastic in Newmains
Across Newmains, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. Common call-outs are for gaps behind new kitchen upstands and gaps opening as the house dries out and settles, on bathrooms & en suites, show homes and kitchens.
Around smaller Scottish places like Newmains, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we’ll cut it out and reseal it.
Do you need new build mastic in Newmains?
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Look out for any of the following:
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
If you’ve bought a new home near Cleland station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Whether the sealant suits the joint
- Whether all the old sealant comes out first
- How long the guarantee is
- What the quote includes, VAT included or not

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
What we can’t put right
We will not take on work that won’t last, so these are the limits:
- A tray or bath that isn’t properly supported, until it’s fixed
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
Joints and surfaces we work on

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. For a place like Newmains, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Why act early in Newmains
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What we need to know
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Any access issues, like height or stairs
- The rough size of the job
