How to look after the new joints
A little care helps the new joints last. We recommend:
- Do not paint over the silicone
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
About our window mastic in Aird Tong
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on timber windows & doors, aluminium frames and patio & French doors, and common reasons people get in touch are white mastic on grey or black frames and gaps where the sill meets the wall.
In and around a place like Aird Tong, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Aird Tong homes and the weather
Aird Tong 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Whether the job is in Aird Tong itself or nearby, the right material for each joint matters as much as a neat finish.

Do you need window mastic in Aird Tong?
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
People generally contact us after spotting something like this:
- Mastic that’s falling out in pieces
- White mastic on grey or black frames
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
Around Aird Tong, as everywhere, window mastic is only as good as the preparation behind it.

Why act early in Aird Tong
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes most of a day for a typical house, less for a few frames. Outdoor work around Aird Tong 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.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

Advice
Aird Tong questions
Is Aird Tong within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect window mastic in Aird Tong?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
How do I get a quote for window mastic in Aird Tong?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.

Surface by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
