Window & door mastic in Greycrook, Scottish Borders
Window and door frames in Greycrook need attention? We cut out the old, prepare the joints and apply the right sealant.
- A bead that doesn’t match the frame
- Hard, cracked sealant around windows
- Draughty joints inside around the window
About our window mastic in Greycrook
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Common call-outs are for water coming in at the bottom corners of a door and whistling draughts around closed windows, across aluminium frames, timber windows & doors and patio & French doors.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Each job carries a 12-month guarantee, whatever its size.

DIY versus a professional finish
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again.

What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a place like Greycrook, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why choose Mr Mastic in Greycrook
- Colour picked to suit the job

Different surfaces, different methods
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.

Greycrook homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Around Greycrook, as everywhere, window mastic is only as good as the preparation behind it. For an older house near a landmark such as St Boswells Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Walk round the house once a year and look at the joints
- Keep paint and stain on wooden frames in good order
- Don’t paint over the silicone
- Wash the frames with mild soapy water
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
