Window mastic for homes and businesses in Blackburn
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. If you are dealing with cracked sealant at the sill ends and rain getting in at the frame or under the sill, we can help, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Penetrating damp from a failed cavity tray or render

Can resealing stop a draught around my window?

Aftercare tips
Aftercare is simple:
- Paint up to the joint, not over it
- Check the mastic once a year
- Wipe condensation off the frames
- Wash the frames with mild soapy water
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

Surface by surface
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
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 keeps the clean look.
Why act early in Blackburn
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. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.

Windows and doors in Blackburn
Historic houses like Howden House (about 4.3 miles east) are a reminder that the area around Blackburn has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Bathgate station, renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Bathgate Academy, larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
