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.

We engaged Crystal Complete Building to add a new level access bathroom to our home. 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.
