Questions from Innerwick
Is Innerwick in your area for new build mastic?
Yes, Innerwick 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.
Will you come out to Innerwick?
Yes. Innerwick is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What does new build mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
About our new build mastic in Innerwick
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on bathrooms & en suites, kitchens and plot handovers, and the jobs we see most are cracked sealant around new window and door frames and shower seals failing in the first year or two.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
There’s a 12-month guarantee on every job, large or small.

What new build mastic looks like in Innerwick
Innerwick is close to 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 Dunbar station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Innerwick, as everywhere, new build mastic is only as good as the preparation behind it.

The process
When we arrive, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. The work generally takes a few hours in a single home. For a place like Innerwick, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Keeping the joints in good condition
Looking after new joints is easy:
- Watch for new gaps as the house dries out
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with right away
- Photograph failed sealant before it’s redone
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
What happens if it’s left?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. In an older home around Innerwick, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Quotes for new build mastic in Innerwick
You will get a clear quote before we start. It’s based on:
- The old material and how stubborn it is
- Any mould that needs treating
- How many areas need sealing
- The size of the job
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Whether it has been sealed before
- Where the property is
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
- Cracking that points to a structural problem
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We cut it out and start again.

What else we do in Innerwick
What the job involves on each surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
