What our Clients Say Crystal Complete Builders built an extra bedroom along with a study during April and May 2012. We would have no hesitation recommending this family builder for a number of reasons. Price - they were good value, offering excellent work and attention to detail. Commitment - they said they would finish by the end of May and they were, working long days to complete on time. Professional - they were very hard working. They were friendly, very tidy and especially respectful to our neighbours. Brian & Geraldine Kavanagh, Raheny, Dublin 5 We have no hesitation in recommending Crystal. From our first contact with them everything ran smoothly and professionally. Phonecalls were returned, work was carried out within budget and on time, a clean site was maintained at all times, ideas were generated that worked in our space. On the whole an excellent experience for us. When your neighbours notice how well they work, it has to be a recommendation in itself! They are professional, courteous, conscientious and very personable. Niamh Allman, Dunboyne, Co. Meath The project was scheduled to take 12 weeks and true to their word, Crystal Complete Building completed the project on time and within budget. Daragh Carolan was our main point of contact throughout the project and we found both him and the team, including Stephen and Seamus Carolan, easy to deal with, reliable and trustworthy. Crystal Complete Building provided us with very helpful suggestions at the design stage which undoubtedly improved the overall appearance of the end result. All variations that arose during the project were agreed in advance and priced reasonably. Daragh Clarke, 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. Thomas & Karan Nesbitt, Clontarf, Dublin 3 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. Eileen Gannon, Dunshaughlin, Co. Meath In 2009 we employed Crystal Complete Building to extend our home. The project was a large scale going from a 510 square foot cottage to a 3800 square foot dormer bungalow. Daragh helped design and plan our new home with great attention to detail to ensure our home was completed on time and in in budget. At all times we felt comfortable with Crystal and their employees and cant thank them enough for the wonderful home they have created for our family. I would highly recommend Crystal for any type of building work. Sharon Lynch, Drumconrath, Meath I have used Crystal Complete Building for a Renovation I was doing on my house.

James Quigley, Dublin 11 I would have no hesitation in recommending Crystal Complete Building as a small family building business. The quality of work which they provide is second to none, and their work ethic is such that I found it a pleasure to have them under take two separate tranches of work. Finally, in terms of neatness and punctuality, they tick all the boxes.
