Window mastic in Sulaisiadar

If you are dealing with black, perished sealant on frames and gaps where the sill meets the wall, 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.
Whatever the size of the job, it’s backed by our 12-month guarantee in Sulaisiadar and across Na h-Eileanan Siar.

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

Honest limits
In fairness, there are a few things sealant will not fix:
- Soft or decayed wood in the frame
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Timber windows & doors
- Window sills

Different surfaces, different methods
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.

What window mastic looks like in Sulaisiadar
Sulaisiadar is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Island weather, with its wind and salt spray, is tough on the mastic around window and door frames.
For jobs in and around Sulaisiadar, choosing the right material for each joint is as important as a tidy finish.
