Ideal Builders Construction
Mairtin Ó Tuairisg is the founder and general contractor of Ideal Builders. With twenty years in the building trade, my interest and passion for carpentry stems back to my youth in the west of Ireland. Growing up and watching my father as a highly skilled carpenter fueled my desire to follow in his footsteps. It was with him that I began my training. As a mentor he provided me with a very solid foundation as well as a unique yet practical approach to building construction.
