New build mastic in Shieldaig
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have joints pulling apart as timber shrinks and untidy sealant flagged on a snagging list, we can help.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
All our work comes with our 12-month guarantee, wherever you are in Highland.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. Somewhere like Shieldaig may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Mention any parking rules near the property
- Move anything stored near the joints
- Mention if the joints have been sealed before

Related advice
Looking after it afterwards
So the new joints stay in good condition:
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Record problems with dated pictures
- Resist patching a failed seal with a tube from the DIY shop
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

New build mastic around Shieldaig
Shieldaig 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. Shieldaig is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Whether the job is in Shieldaig itself or nearby, the right material for each joint matters as much as a neat finish.
Shieldaig (Gaelic: Sildeag) is in Highland. We provide new build mastic to homeowners, landlords and businesses in Shieldaig and nearby, as part of our work across Highland. Our Highland coverage runs to 253 places, Shieldaig among them.
Work in IV54 works the same way as everywhere else we cover. If you need new build mastic at a property on Baile Shuas and Mary Street or anywhere close by, our applicators can take on the job. Close by, we work in Torridon (5 miles east), Applecross (9 miles south-west), Miltown (9 miles south-west), Lochcarron (10 miles south-east) and Srath Carran (11 miles south-east).

What the job involves on each surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. We’ll plan around viewing times.
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.
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. If you’re unsure which you have, drop us a line at info@mrmastic.co.uk with photos and we’ll tell you. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Do you need new build mastic in Shieldaig?
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry first.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- Sealant work across a run of new homes
In and around Shieldaig, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- What insurance they hold
- Whether they seal over old material or remove it
