New build mastic for homes and businesses in Corran
Across Corran, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you have sealant work across a run of new homes and new-build shower sealant that has already split, we can help, whatever the surface.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished 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.

Aftercare tips
A little care helps the new joints last. Our advice:
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
- Get a leaking seal dealt with right away
- Use the extractor fan every time you shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the cost of new build mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- How easy the joints are to reach
- How many areas need sealing
- Which sealant suits the joint
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk.
What to tell us for a quote

- Where the property is
For new build mastic in Corran, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. 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.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
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 happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes anything from a few hours to several days, depending on the number of plots. Outside jobs in Corran need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Keep children and pets away from the work area

Your questions about new build mastic in Corran
Can you do new build mastic in Corran?
Yes. Our work covers the whole of Scotland, and Corran is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Will you come out to Corran?
Yes. Corran is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish and agree it with you.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. Once that is done, or if they won’t put it right, we can reseal it properly.
What we cannot put right
Before booking, it’s worth knowing the limits too:
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Corran is within about 1 mile of 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, and as the frame dries and settles, skirting and sealant joints can open up.
For jobs in and around Corran, choosing the right material for each joint is as important as a tidy finish. In and around Corran, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
