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. We hope to work more with Stoneer during the year and look forward to sharing project imagery with you in the future.

We Treasure Our Home!

Building is an enormous and stressful process but the end results are wonderful and we treasure our home everyday in a way which you only can if you have built yourself. As you know we love the cladding stone and remain extremely grateful for all the help you and your team gave us towards achieving our goal.

Donegal Quartzite, A Big Plus!

I am big fan of McMonagle Stone and have done a lot of work with them over the years.

We have just completed a carport and ramp for our disabled daughter using stoneer on the outside walls and adjoining garage. We used Donegal Quartzite sawn paving on the floor which meets the requirements of our Occupational Therapist.

This is fantastic and a big plus as they are so hard to please. We were so grateful to Caroline for all her help and guidance over the years. Our next plan is to use Mc Monagle Stone on the porch conservatory and full gable wall just waiting on our stone mason to get back to us.
