Shieldaig Window Mastic
Problem with your window and door frames in Shieldaig? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Rushed sealant from a window installation
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
Window mastic in Shieldaig, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you have gaps between the frame and the inside reveal and gaps left after new windows were fitted, we can help, on composite doors, timber windows & doors and patio & French doors alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Shieldaig homes and the weather
Shieldaig is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Shieldaig, as everywhere, window mastic is only as good as the preparation behind it.
Shieldaig (Gaelic: Sildeag) is in Highland. Homes, rented property, offices and hotels in Shieldaig can book us for window mastic. The work is guaranteed for a year. Across Highland, we cover 253 places, and Shieldaig is one of them.

What sealant work cannot fix
We will always be straight with you, so here’s what new sealant will not do:
- A door that needs adjusting, rehanging or new seals
- Broken hinges, locks or handles
- Damp coming through the wall itself rather than the frame joint

What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. Outdoor work around Shieldaig depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Getting ready for the visit

Common problems we fix in Shieldaig
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Common reasons people contact us are:
- Gaps where the sill meets the wall
- A bead that does not match the frame
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
For jobs in and around Shieldaig, choosing the right material for each joint is as important as a tidy finish.
Before you book anyone
- How long the guarantee is
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
- Whether the sealant suits the joint
Looking after it afterwards
To keep the joints looking good and working properly:
- Look round the frames every year or so
- Keep paint off silicone joints
- Ventilate rooms so frames do not stay wet inside
- Repaint timber before it’s bare
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

Will you come out to Shieldaig?
Yes, Shieldaig is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
How many windows can you do in a day?

Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Are you fully insured?

Why it’s worth doing now in Shieldaig
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. 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.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Why choose Mr Mastic in Shieldaig
- A 12-month guarantee on all work
- Quality sealants from Arbo and Everbuild
