'This year we in Killoughteen NS were thrilled to move into our new school extension which comprised of 2 ASD classrooms with ancillary accommodation, sensory room, sensory garden, safe play area, 2 mainstream classrooms and a GP Hall. The building works were completed by O’Callaghan Brothers Builders. I can truly say that it was a very positive experience dealing with both Aidan and Ciaran of O’Callaghan Brothers Builders throughout this process. From the initial meeting, we as a school were very much listened to. The day to day running of the school was virtually unaffected even by the large scale of works that were going on. The entire team was extremely professional, knowledgeable and reliable. Aidan was excellent to keep us informed throughout the build. All timelines were maintained and everyone knew what was happening and when throughout the build process. The whole team were excellent and were meticulous about the quality of their work. When it came to snagging at the end of the project, there was literally nothing on the snag list. We are so proud of our new school. It is absolutely stunning and we will be forever grateful to Aidan and Ciaran of O’Callaghan Brothers Builders. Adian and Ciaran, we just want to say ‘Míle Buíochas’ to you and your team. I can without hesitation recommend O’Callaghan Builders for any building project. I wish you every best wish for the future.

The Primary Care Centre at Kealgorm House in Castleisland, Kerry was a challenging project as it required a phased development plan to ensure that public health services would be provided with continuity and the minimum disruption.

O'Callaghan Brothers Ltd, through service sensitive planning and with a strong project management emphasis, delivered the Centre on time and with appropriate engagement and communication with all stakeholders. They showed their capacity for efficiency and responsiveness throughout the project and their professionalism throughout was exemplary.

We would have no hesitation in recommending O'Callaghan Brothers Ltd for similar significant developments in the future.

O'Callaghan Brothers, Castleisland came on board with Cordal Community preschool & playgroup to construct a new independent childcare facility on the grounds of Kilmurry National School. This new facility was due to commence in April 2020 but however due to Covid-19 and HSE guidelines construction work had to be suspended in these unprecedented times.

The 1st footing was dug out on the 1st June, 2020 and our new facility was operational from the 7th September, 2020. This was a tremendous accomplishment as it was a very demanding project with such a tight timeline for completion.

Our experience had been very positive from the moment we first consulted with Aidan. Himself and his colleagues performance was absolutely outstanding in the areas of management, communication, professionalism and completion. Every task was performed on time and with attention to detail. If requests for further tasks were suggested that were not part of the contract these were accommodated with a pleasant and cheerful manner.

O'Callaghan Brothers go above and beyond in what is required to make the customer happy and we are grateful to have chosen them to build our new childcare facility.

We would like to wish Aidan and Ciaran continued success.

Martin Buckley & Associates Mechanical and Electrical Consultants have recently worked on the Castleisland Primary Care Centre at Kealgorm House. The main Contractors on the project were O’ Callaghan Bros Ltd. Castleisland.

We were very pleased to work with them on this project and found them to be excellent builders with a very modern and efficient approach to executing and managing the project. The project ran very smoothly with full cooperation from all participants mainly due to the efficient performance of the Main Contractor. We would be very pleased to work with them again in any future project.

On behalf of Mahoonagh National School, I cannot speak highly enough of O’Callaghan Brothers Builders who were awarded the contract to construct our new ASD Suite of classes, associated rooms and two new mainstream classrooms last year.

The communication process which we had with Ciaran and his team was excellent ahead of the works, at the pre-planning stage, during the construction work and at the snagging stage. The entire team are extremely professional, knowledgeable and very reliable. A regular communication process meant that our timelines were maintained and everyone knew what was happening and when throughout the build process.

The team sought to ensure that the building process did not interfere with our school’s day-to-day work and that our needs were always met. Also, the pupil’s routines were disrupted as little as possible and for that, we are very grateful. The team were onsite at weekends and during holiday periods to get the project completed on time.

Our sensory garden is a wonderful asset for all our school to enjoy, offering a calming, therapeutic approach to our pupil’s sensory development. Our stunning extension is extremely well-finished and we are very proud of the finished product.

Ciaran and Aidan are a pleasure to deal with and I highly recommend them for any similar project. I wish them every success for the future.

We recently had the pleasure of having O'Callaghan brothers renovate our home. To see Ciarán and his crew bring plans to life was amazing.

Nothing was a problem to Ciarán and from the beginning he included us in every decision. He always had our best interests at heart. Many people talk of the stress involved in renovating/building but I can honestly say it was a pleasure with Ciarán and his crew. Ciarán was on site most days and was always easy to contact.

The end result is a fantastic home built to the highest standard that is down to Ciaran's attention to detail and hard work. I would recommend O'Callaghan Brothers to anyone with complete confidence in their superb work. Thank you so much.

O’Callaghan Brothers, Castleisland were awarded the contract to construct our ASD special classes and associated rooms. I would wholeheartedly recommend them for any construction project that may arise.

The project came in on budget and four months earlier than planned. They had workers on site at weekends and holidays to get the project completed before September 1st. The sensory garden designed by the contractors themselves is now a show piece in our school.

The building is extremely well finished and the project manager commented on how few snags were listed and they were rectified within a week. The O’Callaghan brothers built a stunning extension for us and we are extremely proud of the finished product. Ciaran and Aidan are a pleasure to deal with.

I wish them every success going forward.

We recently completed the mechanical and electrical engineering consultancy services at the new €1.3million ASD extension at Presentation Primary School, Castleisland, Co Kerry. O’Callaghan Brothers were the main contractors who constructed the building.

In my dealings with O’Callaghan Brothers throughout this 11 month project, I found them to be professional, knowledgeable and easy to deal with. The mechanical and electrical services construction was supervised by O’Callaghan Brothers ,and the work was completed to a high standard.

I would have no hesitation recommending them for any similar project.

Once the initial burst of excitement at having finally received planning permission subsided we were daunted by what lay ahead. We were clueless, perhaps ignorant to the process of building a house. We knew the guidance and expertise of a contractor would be required, but the task of selecting one of these in itself felt a challenge.

The tendering process led us to the O’Callaghan Brothers and in hindsight, as I type in our beautiful home, we struck gold. I’m sure our frequent, ludicrous questions posed at all hours would have frustrated the most tolerant of people but Ciaran advised and assisted us throughout. We were confident that each trade carried out their roles to the highest standards. We felt well versed and well informed on heating systems, insulation , electrical, joinery etc. We are thrilled with our home. It is a comfortable home in all regards, finished to such a high standard by Ciaran and Aidan.

We had heard so many horror stories from our friends about their experiences of building but am glad to say we did not share in this. We are full of praise for the boys but above all we feel the greatest asset to their working relationship is the communication with the client. This was invaluable to us.
