What new build mastic looks like in Kirkwall
Kirkwall is close to 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. Work on the islands has to be planned around ferry crossings and the weather, so give us as much notice as you can.
For jobs in and around Kirkwall, choosing the right material for each joint is as important as a tidy finish. Around Kirkwall, as everywhere, new build mastic is only as good as the preparation behind it.
Kirkwall is in the Orkney Islands. Whether you’re in the middle of Kirkwall or further out, we cover new build mastic for every kind of property. Across the Orkney Islands, we cover 51 places, and Kirkwall is one of them.
We cover every part of the KW15 postcode area for new build mastic. Whether your property is on Main Street, Sommerville Square and High Street or a nearby road, our applicators can take on the job. Kirkwall sits on or near the A960 and A961, which makes travel easy.

How we handle new build mastic in Kirkwall
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. Common call-outs are for internal frame sealant that has split and smeared, uneven beads picked up at snagging, on bathrooms & en suites, kitchens and plot handovers.
A lot of new homes in Scotland are timber-framed, and they settle in their first years, so skirting and floor joints can open up in the first year or two.
There’s a 12-month guarantee on every job, whatever its size.

What the job involves on each 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 with baths filled first.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Cracking that points to a structural problem
- Baths and trays that move too much for sealant to cope with
- Broken tiles or a split tray
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Kirkwall questions

Not at all. The area is protected while we work and cleaned up afterwards.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Don’t wait for the house to settle if water is getting through
- Keep photos and emails about snagging items
- Follow the cure time we give you
- Avoid scourers and strong chemicals on sealant
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours in a single home from start to finish. A visit in Kirkwall needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any parking rules near the property
How to get a quote
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
Advice
Landlords, agents and businesses in Kirkwall
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Housing providers, facilities teams and property managers book us too in Kirkwall and across the Orkney Islands. Several sites can be quoted together.
Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Why it’s worth doing now in Kirkwall
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. If you live in a flat in Kirkwall, failed sealant can send water to the neighbours below, which turns a small job into a bigger one.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
