New build mastic in Robroyston, done properly
We work in new homes and on new-build sites across Robroyston. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. Common call-outs are for leaking shower tray seals in a new home and smeared, uneven beads picked up at snagging, across bathrooms & en suites, skirting & floors and plot handovers.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. For a flat in Robroyston, a flexible sealant copes with that movement where filler would crack.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours in a single home, depending on how much there is to do. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Robroyston, tell us the floor, how the door entry system works and where we can park nearby.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

What affects the quote in Robroyston
Every job gets its own quote. These are the things that affect it:
- The type of sealant required
- The amount of work
- How easy the joints are to reach
- Any mould that needs treating
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Any access issues, like height or stairs
- If someone has resealed it before
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
What the job involves on each surface
Plot handovers
Developers can send the plot schedule and specification for a quote. Sealant work across the plot is covered to the agreed spec.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Settlement cracks that need a surveyor
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.
Surfaces we seal

New build mastic around Robroyston
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. Robroyston 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.
If you’ve bought a new home near Robroyston station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Robroyston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Robroyston
I let a flat near Robroyston station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do new build mastic in Robroyston?
Yes. We work across all of Scotland, and Robroyston is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Are you insured?
Yes. We’re fully insured for every job we do.
