New-build mastic & snagging in Portmahomack, Highland
Plot mastic for developers and snagging failed sealant in new homes in Portmahomack, with a one-year guarantee on every job. Ask us for a quote.
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How we handle new build mastic in Portmahomack
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you’re dealing with new-build shower sealant that has already split and untidy sealant flagged on a snagging list, we can help, on plot handovers, bathrooms & en suites and kitchens alike.
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.
Our work is backed for twelve months.

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 normally takes a few hours in a single home. Somewhere like Portmahomack may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Report sealant problems to your builder during the snagging period
- Keep pictures and emails about snagging items
- Use the extractor fan every time you shower
- Resist patching a failed seal with a tube from the DIY shop
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
For landlords and businesses
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Different surfaces, different methods
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. We will plan around viewing times.

Common questions in Portmahomack
Can you do new build mastic in Portmahomack?
Yes. Our work covers the whole of Scotland, and Portmahomack is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Will you come out to Portmahomack?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work through snagging lists?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
How do I get a quote for new build mastic in Portmahomack?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We choose one to suit the room before we begin.
