Polwarth New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in Polwarth. Fully insured, ARBOMaster approved and guaranteed for a year.
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- Gaps between new skirting and floors
New build mastic in Polwarth, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on windows & doors, bathrooms & en suites and plot handovers, and the jobs we see most are skirting joints opening in the first winter and smeared, uneven beads picked up at snagging.
New flats and houses are still being built in and around Scotland’s cities, and new-home owners often find sealant snags in the first year or two, in Polwarth as anywhere.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Honest limits
In fairness, some problems need a different trade:
- Disputes or warranty claims with your builder
- A tray or bath that is not properly supported, until it’s fixed
- Settlement cracks that need a surveyor

Questions from Polwarth
Can you do new build mastic in Polwarth?
Yes, Polwarth is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
I let a flat near Slateford station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. Once that’s done, or if they will not put it right, we’ll cut it out and reseal it.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with pictures if you can. We will flag anything that needs another trade.

What affects the cost of new build mastic
Your quote is based on your job. We take into account:
- How easy the joints are to reach
- How much there is to do

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints

Joints and finishes in Polwarth homes
Polwarth is within about 3 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Slateford station, it’s worth checking the sealant early, while snags are still fresh. Around Polwarth, as everywhere, new build mastic is only as good as the preparation behind it.

Why it’s worth doing now in Polwarth
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Polwarth, damp can travel a long way before it shows.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Take a look at our cost guide and customer reviews.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the number of plots. In a city area like Polwarth, parking may be by permit or pay-and-display, so tell us what’s nearby. If you’re in a flat, let us know how we get in at the street door.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
