Darragh and the lads did the most amazing job on my en-suite bathroom. Couldn’t have had been more helpful, professional, friendly, respectful of my home especially as I was working from home while they were on site. Darragh helped me pick colours, tiles, all finishes and explained everything in detail reassuring me every step of the way in the decision making process. I would highly recommend Crystal for any job, I wouldn’t hire anyone else. Very reasonable pricing and they left my house spotless afterwards! Thanks a million Darragh 😊

Daragh and his team did a fantastic job on the work we needed doing on our house. Despite the constantly changing lockdown rules, Daragh managed to get all the work done efficiently and quickly, which we were really grateful for as we have young kids and we had a lot of differing jobs done and the quality of excellent. Couldn't have wished for more helpful and pleasant people to do it either.

From the planning stage to the end result our experience with Daragh ,Stephen and the team was exceptional, they were friendly, helpful, and knowledgeable They had a great work ethic, starting promptly at 8am, working long days and tidied up each evening leaving the building safe and secure. Daragh and Stephen consulted at various stages of the process, advising and making best use of the space available but always with disability access in mind.We are delighted with our new bathroom, completed to a high standard and have no hesitation in recommending Crystal Complete Builders for any work

I would absolutely recommend Crystal Complete Building. I found them friendly, professional, punctual and very well priced. We are delighted with the end result and it was the best decision for our family to employ them to extend our kitchen. The work was completed on-time and within budget.

Crystal Complete delivered a great result for me on my tricky old house, with massed concrete & granite walls like the Waves of Tory. They insulated, plastered, replaced windows and floors etc very satisfactorily, finding solutions to all the building's problems. The rooms are now cosy and crisp, a pleasure to be in.Tidied up after themselves each evening, very clean work Polite and pleasant, started punctually early every morning. Great work all round.

From beginning to end our experience with Daragh and Stephen was exceptional. From a design perspective Daragh went above and beyond....in truth doing the job of an architect. Throughout the course of the project the scope expanded from an initial extension, to a clearing of an overgrown garden and finally a patio - this was due to the level of confidence we had in the team. We were very happy with the end product and would have no hesitation in recommending Crystal Complete Building. The post completion support service was also excellent.
Eileen Gannon, Dunshaughlin, Co. Meath We used Crystal to build a third story sunroom on our private residence. Both ourselves and our surveyor found Daragh Carolan to be very competent, efficient, and helpful. During the construction Daragh and his crew were friendly and approachable but polite and unobtrusive. They were punctual and kept affected areas clean. The project was finished on time with no complications and we are delighted with the results. I would not hesitate to highly recommend Crystal Complete Building for any similar work.

Thomas & Karan Nesbitt, Clontarf, Dublin 3 The work was carried out in an efficient manner with minimal disruption to our family life. At the end of each day the area was cleared of debris and tidied thoroughly. The building area was cordoned off and made safe which was comforting given the number of small children who play on the road each day. We found Daragh and Stephen to be helpful, friendly and knowledgeable at all times and engaged them to carry out additional work as a result. The timescale for completion of works was 10 weeks and despite temperatures of minus 10 degrees and heavy snowfall the works were complete on time. We are extremely please with our new extension and would have no hesitation in recommending Crystal Complete Building.

Aveen & Eoin Foster, Skerries, Co. Dublin Crystal Complete Builders completed an extension for us just before Christmas 2014. We went with them for a number of reasons: competitive price, impressed with the hours they put in & work completed on a neighbours home. But what sold us was our initial meetings with Daragh - we liked and trusted him & his expertise, everything was easy!! This followed throughout the build, any questions we had were promptly answered, his team was always very respectful of us & our neighbours. They would put in long hours in any weather condition & the weather was pretty brutal the first few weeks of November! At the end of everyday they would clean & make the area safe, which was very comforting with 3 young children. Their professionalism, dedication and reliability is outstanding, and they made the whole build a stress free experience. We are delighted with our extension & wouldn't hesitate to use them again.
