DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We cut it out and start again.
New build mastic in Newbie, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We are often asked to deal with frame joints opening as the plaster dries and sealant work across a run of new homes, across show homes, bathrooms & en suites and plot handovers.
Around smaller Scottish places like Newbie, 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.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Different surfaces, different methods
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. We’ll plan around viewing times.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
What affects the quote in Newbie
Every job gets its own quote. This is what makes a difference:

- The type of sealant required
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.

New build mastic around Newbie
Newbie 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.
If you’ve bought a new home near Annan station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Newbie, as everywhere, new build mastic is only as good as the preparation behind it.

When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with

Your questions about new build mastic in Newbie
Will you come out to Newbie?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you cover Newbie for new build mastic?
Yes, Newbie is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
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.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Landlords, agents and businesses in Newbie
Housing providers, facilities teams and property managers book us too in Newbie and across Dumfries and Galloway. Several sites can go on one quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. 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.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.

The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours in a single home in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- 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.
- Each bead is tooled and the cure times explained.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
