At R&J Building Services, we work with customers to ensure we always meet their expectations. One of the most common problems property owners face is the prospect of expensive relocations, as their families or businesses grow in size.

We can organise planning on your behalf and offer a helpful, non-disruptive, reliable construction service.

  • Jon @ R&J; completed a very large project for me over the course of 2015. I honestly could not recommend him and R&J; highly enough. They are extremely friendly, knowledgeable, professional and skilled in all areas of work undertaken. Above all else they are fair and trustworthy with pricing and deliver the highest of quality and pride in what they do. ***** FIVE stars.
