Customer testimonials

Hear it from our happy clients: building your vision, one success story at a time.

"JD Mooney's team expertly extended our kitchen into an open-plan living space, complete with a bathroom, utility room, and pantry. They worked swiftly, maintaining very high standards throughout. The team were always available for queries, offering reassurance and advice. JD Mooney’s professional, hard-working team delivers high-quality results. I know I can always reach out to the team for any issues or advice."

Margaret, Blackrock

"The team brought creative design to transform our ugly sheds and awkward layout of patio. The sheds are now functional, damp-proof and clean and modern looking, and the new patio opens up our outside space. A pleasure to work with: on time, polite, friendly, flexible and within our budget. We would highly recommend for big and small projects."

C&N, Kildare

"The work is finished and we are delighted with every part of it. I was thrilled to get the gorgeous flowers when I came home at 5:30. A very thoughtful and generous deed. Thanks to you all at JD Mooney for really excellent attention over many years of projects and especially for this year"

Mary, Kildare
