Window mastic in Forbes
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on timber windows & doors, composite doors and aluminium frames, and the jobs we see most are gaps left after new windows were fitted and sealant in the wrong colour for the frame.
In and around a place like Forbes, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
All of our work is guaranteed for twelve months.

How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Forbes 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.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules

Surface by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Do you need window mastic in Forbes?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
It’s worth asking for a quote if you see:
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
- Cracked sealant at the sill ends
For site and facilities teams at buildings such as Alford Academy, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Who does the work, and how experienced they are
- What happens if the job turns out different
- Which sealant they’ll use, and why
- Is VAT in the price?
Looking after it afterwards
After the cure time, these simple habits help:
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
- Keep paint off silicone joints
- Ventilate rooms so frames do not stay wet inside
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

Window mastic in Forbes: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In the older streets around Alford Parish West Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
