  • June 2026 External Wrap, Cavity Wall and Attic Insulation. Chimney blocked and vents inserted in all of the rooms and attic. I would like to thank Tony, the project manager and Niamh in the office for such a good experience (and all the Bluebuild people who worked on our house). Bluebuild carried out all works in a timely, professional manner with minimum distruption. They organised everything and helped with the grant paperwork. I would have no hesitation recommending Bluebuild.

  • We recently had external insulation installed on our home, and we couldn't be happier with the entire experience. The professionalism shown by everyone involved was outstanding. The quality of the workmanship is excellent, and the attention to detail is clear in the finished result. The installation crews were incredibly hardworking, friendly and courteous. They arrived early each day, worked efficiently, and were always happy to answer any questions we had. The management team were equally impressive. They were approachable, helpful and very accommodating throughout the project, making the whole process straightforward and stress-free. Nothing ever seemed like too much trouble. The work was completed much quicker than we expected, without any compromise on quality. The team also took great care to keep everything clean and tidy, leaving the property in excellent condition when the job was finished. We are absolutely delighted with the final result and would have no hesitation in recommending this company to anyone . A first-class service from start to finish. We'd like to specifically thank Michael, Colm, Lulian and his crew and Niamh the secretary!
