"From our initial contact with JW Insulation, Katherine gave us the customer service you would expect and need when you are self building. She kept us up to date with our order, lead times and deliveries. Everything went smoothly from start to finish.
Insulation day was great, the guys kept us informed with what they were doing, being sure to enquire about our neighbours to show them respect with working hours. The job itself was done correctly and looked fantastic- who knew an insulated roof could look as a perfectly upholstered settee! They cleaned up after themselves too. We would definitely recommend this company for all your insulation needs.
Thank you to all, it was a pleasure having you work on our new build."

Working with Ray and the team at JW Insulation has been nothing short of outstanding. Ray and Katherine bring a level of professionalism, reliability, and attention to detail that’s increasingly rare in the industry. From the initial communication to the completion of works, every stage of the process was handled with transparency, expertise, and a genuine commitment to quality.
What truly stands out about Ray is his integrity and consistency. Even under tight project timelines, he and his team delivered exceptional results without compromising on standards. It's clear that JW Insulation takes great pride in their work - and it shows in both the finished product and their customer service.
I would not hesitate to recommend Ray and JW Insulation to anyone looking for a trustworthy, high quality insulation contractor. We look forward to continuing our working relationship on future projects.
