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.

What Our Customers Think

James and his team have completed a large project to build a 2 storey extension and re-model our extension. All of the JMW team have been punctual, have turned up as planned and have done a great job. It has not been a problem having them in the house.

The finished project is great!

JMW recently completed a unique contemporary low carbon single storey extension for our home. James was enthusiastic about our project from the start and we had a shared vision on how it should be realised. All of his team were polite, friendly and a pleasure to have working in our house.  It is great to see him supporting the education of a number of apprentices under the guidance of his highly skilled leads. We are really happy with the end result and it has transformed our home.

JMW recently completed our two storey side extension. We are so happy that we had James & co to take on our project. They were able to start quickly & were friendly and professional throughout. James’ whole team were hard working, dedicated and took pride in their work. James & his team took the stress out of the project and we were able to let him manage it which was perfect for us and exactly what we were looking for. We would highly recommend JMW to complete an extension or general carpentry.

Just had a full house renovation and a knock through to create an open plan downstairs by James and his team. They were honest and very professional from the word go. Nothing was too much trouble for them. They even came up with some fantastic ideas that we hadn't thought of.

Our home feels like a new house!!
