Stoneer, A Faster More Efficient Way To Build!

We have completed a number of houses in the Roscomman / Mayo area using McMonagle Stone products. At the moment I am working a lot with your Stoneer range, which I find more efficient and faster to build as it is less labour intensive onsite.

Mountcharles Sandstone, The Best Decision!

Twelve years ago you supplied beautiful stone for our new home, hopefully you remember my husband William. The stone looks beautiful and I still admire it every day. Using Mountcharles Sandstone from McMonagle Stone was one of the best decisions we made when building our own home.
