Hear from Our Customers

  • We had our external insulation done by bluebuild. Colm and his team were a pleasure to deal with from start to finish. They were so friendly and professional all the way through. We’re delighted with the final appearance and the cost was competitive. We had a small issue (caused by us not them!) afterwards and they were so responsive and quick to sort everything out. Would highly recommend.

  • Blue Build recently completed a full energy upgrade on my parents 40 odd years old home in Wicklow Town as part of the SEAI Warmer Homes Scheme. The efficiently, reliability and quality of the work done by the various teams was outstanding. Every worker on the job unfailingly courteous and friendly to my parents, thoroughly cleaning up after every job which minimised disruption to the household hugely. Jason, the wonderful project manager, checked in regularly to keep abreast of the work as it progressed. We highly recommend Bluebuild. Many thanks to Jason and everyone on the Bluebuild team.

The Problem

Many homes built before modern insulation standards lose a large portion of heat through solid or poorly insulated walls. This can lead to:

  • High heating bills
  • Cold rooms and draughts
  • Poor BER rating
  • Condensation and damp issues

The Solution

External Wall Insulation wraps your home in a high-performance insulation system that:

Keeps heat inside your home
Improves comfort year-round
Modernises the look of your property
Reduces energy costs long-term
