Testimonials

What our clients say about us

Don't just take our word for it. See what our valued clients have to say about their experience of working with NJ Refurbishments.

"When I decided to carry out a conversion of my 400-year-old barn NJ was the first company I contacted, NJ designed, managed and delivered the entire project and we now have a highly efficient home which is fundamentally a new property encased by an old stone barn. We are extremely pleased with the service NJ provided. It is my pleasure to recommend NJ."

Steward Wood

"We had been recommended NJ by a close friend who had used them on her house. They guided us through the design process which included a beautiful side and rear extension. They took care of the planning and design and once approved, carried out the build in just 18 weeks. We are delighted with the finishes and are enjoying the house which is just like a new build home."
