We recently had our home refurbished by Greenoak construction, and the work they did is beyond anything we could have imagined. Pat and Louise’s experience and input was invaluable, taking our original ideas about the reno and expanding upon them so that we’re now in a house we’re thrilled to be living in. I can’t recommend them highly enough! (And on top of that, they stayed on schedule!!)

With Greenoak Construction, we got both a builder and a house designer. Pat and his team transformed a fire damaged house to a repaired and renovated house. The outcome is an upgraded house with an applied practical design, quality build and an energy-efficient house. They delivered an excellent and comprehensive project. After living in the house for 6 months we are delighted with our home.What evident during the project included:• Safety was always a priority and prominent.• Pat’s availability and communication throughout the project was second to none. He researched good solutions and was proactive in advising of alternatives and being inclusive of our demands and wishes.• Doing the job right and have pride in job well done are important to us and Greenoak Construction.

Greenoak is renovating our kitchen, bathroom and converting our shed to an office. We are very happy so far with the work they are doing, ahead of schedule already! Pat and Louise are very kind and professional to work with. We already see the work in progress is looking grand so can’t wait to see the final product and for us to finally move into our dream home!

Excellent work carried out by Greenoak Construction. Pat was brilliant with ideas and advice, all the lads who worked on our house were fantastic. All our neighbours commented on how clean and considerate they were. Would highly recommend. We’re delighted with our extension.

Pat McCabe and his team at Greenoak are 100% reliable and trustworthy when it comes to devising and delivering construction solutions. We used the firm for a major renovation of a commercial building and subsequent repair and maintenance work. We are happy to recommend the firm.
