What else we do in Smallburn
How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic in Smallburn: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Around Smallburn, as everywhere, window mastic is only as good as the preparation behind it.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Make sure the drainage slots are not blocked
- Ventilate rooms so frames do not stay wet inside
- Keep paint and stain on wooden frames in good order
- Keep jet washers away from the mastic
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Signs you need window mastic in Smallburn
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Keep an eye out for any of the following:
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Mastic that is falling out in pieces
In the older streets around Muirkirk Old Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
