We couldn’t be happier with the work carried out by Greenoak. From the very first consultation to the final finishing touches, their professionalism, attention to detail, and dedication to quality were outstanding.

The team was punctual, courteous, and kept us informed at every stage of the project. Nothing was too much trouble, and they went above and beyond to ensure everything was completed to the highest standard. What really stood out was their craftsmanship and pride in their work, you can see it in every corner of our new space.

They stayed on schedule, kept the site clean and tidy, and delivered exactly what they promised, if not more. Any small issues were dealt with quickly and efficiently, with clear communication throughout. It’s rare to find a company that combines skill, reliability, and genuine care for their clients, but Greenoak does just that.

We wouldn’t hesitate to recommend them to anyone looking for high-quality building work. A truly top-class experience from start to finish.

We engaged Greenoak to complete a demo of existing 70's ground floor extension and full rebuild of new ground floor extension (open plan kitchen/utility/living space, bedroom and bathroom). Greenoak also managed a full rewire, replumb, and partial retrofit of the "old" main house (3bed semi-d). At the initial tender stage we spoke to a number of construction companies, Pat & Louise stood out for their commitment to quality and honest advice on what would be the best use of our budget. We are really delighted with the outcome of the build and would confidently recommend Greenoak to anyone. Pat also had some really good advice around where to place kitchen etc. which we took on board and are grateful for (as we didn't have an architect and 1st time homeowners). Like any build we had some snags, these were all fully resolved by the team. Louise also supported us with the necessary documents for our grant application and endless queries which was great. All of Pat's team members on site were lovely to deal with, very polite and diligent. They were very upfront with costings, we managed to largely stick to our budget and timeline despite some bad weather causing unforeseen delays. Greenoak were also very fair and competitive when we decided to add on some additional finishings towards the end of the project. Greenoak and team take pride in their work and it shows! Thank you!

We recently engaged Greenoak Construction to complete a full kitchen extension and remodel. We are absolutely delighted with the end result. We found Pat, Louise and all the team great to deal with from the first stages of design and all throughout the project. Pat has a super team around him who worked to the highest standards and in a very clean tidy manner. Most importantly, the project was delivered in on budget and ahead of schedule. It was also great to be able to hire a local company to undertake our work. We would have absolutely no hesitation in recommending Pat and his team.

We employed Greenoak over the summer for an extension and an attic conversion. From the moment we engaged with Pat and Louise, we found them to be honest and transparent, giving some great advice over how to get the most out of our budget. Louise kept us up to date on all progress throughout the build, while Pat and his crew had us back in the house on schedule. We are delighted with the job and the extra space created has completely transformed our living situation. Thank you to all in Greenoak!

We had our 3 garden shed roofs replaced.They came out promptly . Started the job about 3 weeks later with their roofing team. Excellent job. Completed in a week. Extremely neat and tidy and very hard workers who know their trade !
Greenoak correspondence was very good by email and phone.
Will get repeat business from us.

I employed Pat and the crew at Greenoak to undertake the €1.2 million refurbishment of the main hostel and conference centre at the National Scout Centre, Tibradden, Dublin 16. They delivered the project on time and within budget. Pat worked hard to whenever problems arose during the build always thinking outside the box to find solutions that enabled the project to be completed within budget. I would recommend Greenoak to anyone seeking a company that will work with the client to bring any project to a successful completion.

We had our house renovated by Greenoak Construction earlier this year, and we are delighted with the quality of work they delivered. In 3 short months they completely refurbished the house to modernise it and make it energy efficient including rewiring, underfloor heating, insulation, open plan kitchen and dining room, upgraded bathrooms and ensuite etc.
Schedule was very important to us and they got us back in by our deadline and on budget. They also accommodated any extra design details we asked for along the way. Pat, Ciaran, Louise and team delivered a great end result for us!

Very good building company. We have recently done an extension and full refurbishment of our house and the job has been carried out within the estimated timeframe and in the budget. I would remark that they are quite flexible and have had our needs into account. From the structural point of view the external engineer we had was very happy with the work. The finishes are very good too. 100% highly recommended.

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!

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.
