About JMW

What you can expect from JMW

At JMW, we pride ourselves not just on our quality of work but on our customer service. As a client of JMW, you can expect us to do what we say we will do, be tidy and polite at all times, and to thoroughly and professionally clean the site at the end of the project.

We will keep in touch with you at all times, and you have access to our project management system, Buildertrend, so you can see exactly what stage we are at, what will be happening next, and who will be on site. We will also upload videos and photos, so you can see exactly how the project is going.

We all proudly wear JMW branded clothing, including any sub-contractors we engage, so you know you are dealing with a member of the team. Most of the team you see are directly employed by JMW, but where we use the services of sub-contractors we always check out at least three references, to ensure their work and behaviour is of the highest standard.

Why Work With Us

We are committed to these core values

We are Masterbuilder and Trustmark approved. We have fortnightly site visits from a dedicated health and safety officer, to ensure your build and our team remain safe on site.

If you would like to work with expert builders and carpenters JMW to create your dream home, we would love to talk to you. Please get in touch.

We promise to

  • Respond to queries within 24 hours
  • Leave your project clean and tidy
  • Turn up when we say we will
  • Be polite and courteous at all times
  • Offer a professional opinion
  • Use quality materials at all times and not cut corners

Recent Projects

Our customers are happy for us to showcase our work in recognition of the workmanship achieved

Old Manor Barn

This stunning barn conversion project is probably one of our favourites and the clients themselves are pretty interesting too!


This project was a little different to other barns we have worked on as the client didn’t want to covert the barn - just have it restored!

West End

For this project, JMW were tasked with converting an existing garage to an annex, and building a rear single storey extension.
