All told, the work takes a morning for a couple of windows and a door. 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.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check the mastic once a year
- Don’t use solvent cleaners on the joint
- Use gentle cleaners on frames and sealant
- Avoid blasting the frames with a pressure washer
Most silicone sealants will not take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
When something else is needed
A few problems are outside what sealant work can do:
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
- A sash or casement that won’t close properly
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

Windows and doors in Newtown
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Newtown is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
