New build mastic in Clestrain, done properly
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, kitchens and show homes, and the jobs we see most are shower seals failing in the first year or two and gaps opening as the house dries out and settles.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Every job comes with our one-year guarantee, wherever you are in the Orkney Islands.

Surface by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Why deal with it now?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around Clestrain, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Over 20 years’ experience
- A 12-month guarantee on all work
- A sealant colour to suit the surroundings
- Sanitary silicone with an anti-fungal additive in wet areas

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Signs you need new build mastic in Clestrain
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
Around Clestrain, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Clestrain: local notes
Clestrain 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. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
For jobs in and around Clestrain, choosing the right material for each joint is as important as a tidy finish.

What we do, step by step
We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for most snagging lists, longer for a run of plots. 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.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints

When it is not the sealant
New sealant cannot fix everything, and we’ll tell you before we start. Sealant will not put right:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- Plumbing faults behind the sealant
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
