How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
About our new build mastic in Isbister
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Common call-outs are for cracked sealant around new window and door frames and sealant applied over dusty or wet surfaces, on windows & doors, plot handovers and skirting & floors.
Work in a place like Isbister is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
You get a 12-month guarantee, the same in Isbister as everywhere else we work.

How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Common questions in Isbister
Will you come out to Isbister?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Isbister in your area for new build mastic?
Yes, Isbister is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What does new build mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Do you have insurance?
Yes, we are fully insured.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the number of plots, including the preparation. We’ll confirm how long when we quote.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, drop us a line at info@mrmastic.co.uk with pictures and we will give you a straight answer. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

- New-build shower sealant that has already split
- Frame joints opening as the plaster dries

New build mastic in Isbister: local notes
Isbister is within about 1 mile 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, so skirting and sealant joints can open up as the building settles.
Whether the job is in Isbister itself or nearby, the right material for each joint matters as much as a neat finish.
Isbister is about 6 miles north-west of Kirkwall, in the Orkney Islands. If you need new build mastic in Isbister, it’s easy to get a quote: please email us at info@mrmastic.co.uk.

- Deciding who is responsible under a builder’s warranty
- Structural cracks in walls or ceilings
- Leaking fittings rather than failed sealant
