We cover Fernieside for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.

New build mastic in Fernieside, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. We’re often asked to deal with beads laid onto grit and dust from the build and kitchen sealant that has pulled off the wall, on bathrooms & en suites, show homes and plot handovers.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. In Fernieside, we cover those floor joints as well as plot mastic for developers.
All our work is covered by a one-year guarantee.

What we cannot put right
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Broken tiles or a split tray
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

What new build mastic looks like in Fernieside
Fernieside is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Shawfair station, the sealant around baths, showers and frames is worth checking in the first year or two.

Fernieside questions
Is Fernieside in your area for new build mastic?
Yes, Fernieside is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Shawfair station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they won’t put it right, we can reseal it properly.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do you need new build mastic in Fernieside?
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
Any of these means the joints need attention:
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
Around Fernieside, as everywhere, new build mastic is only as good as the preparation behind it.

What affects the cost of new build mastic
You will get a clear quote before any work starts. It’s based on:
- The number of rooms or windows
- The type of sealant required
- Whether the work is at height
- When we can work, for business premises
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- The rough size of the job
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Landlords, agents and businesses in Fernieside
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why deal with it now?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. For landlords in Fernieside, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why Fernieside clients choose us
- Anti-fungal sanitary silicone in wet areas
- Quality sealants from Arbo and Everbuild
- Colour agreed with you before we start
- Over 20 years’ experience
Surface by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
What happens on the day
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours in a single home in most cases. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Fernieside, tell us the floor, how the door entry system works and where we can park nearby.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention any tricky access
- Let us know about earlier repairs to the joints
