But don't just take our word about the work we do!  What counts is how you, the client, feels about what we've done.

Do take a moment to read through just a few of the testimonials given by recent McDonnell clients:

"McDonnell Construction was wonderful to work with on the complete remodeling of my house.  Cormac kept in constant communication with me, kept to a tight timetable - always working to a very high standard - and paid attention to all the small details.  His subcontractors were all fantastic and were very hard-working. 

I highly recommend McDonnell Construction to anyone looking to build or remodel."

"Cormac did a complete renovation of an old house in Claddaghduff, Co Galway for us in 2015. We found him hard working, punctual and scrupulously honest. He does excellent work and employs only the best tradesmen for specialist tasks. If a problem arises, he will do his research thoroughly and come up with a good solution. He takes great pride in doing a job well and we are delighted with the job he did for us.

Cormac is a pleasure to work with and we recommend him highly."
Margaret and Mark McGuckin

"McDonnell Construction built my dream home in Claddaghduff, Connemara, supervising every aspect of the house.  Cormac himself was a model of professionalism - in terms of client focus, perfectionism, collaboration and attention to detail (the house was built on time and on budget).  Cormac takes immense pride in his work and I wouldn't hesitate to recommend him for any project, large or small."
