Welcome to the Rewinds & J. Windsor website

Welcome to the home of Rewinds & J. Windsor, one of the largest independently owned electric motor and rotating equipment repairers in the UK. From mechanical and electrical repairs to electrical manufacturing and sales, at Rewinds & J. Windsor we have been setting the standards for engineering solutions for over 60 years.

Established in 1946 by J I Windsor the company originally focused on ship repairs, as was the demand at the time, but quickly grew and expanded to electric motor repairs and land-based industrial repairs. Since then our rapid expansion has seen us become one of the UK’s largest, most experienced and most trusted electrical and mechanical repairs companies.

Operating across three sites and servicing the whole of the UK and Ireland we now offer not only mechanical and electrical repairs and maintenance services, but also manufacturing and custom builds, and an online store for new product sales of electric motors, pumps and more.

We pride ourselves on delivering our engineering services quickly, efficiently and to the highest quality, so that our customers can in turn focus on delivering their services to their customers.

The back bone of our business has always been electrical and mechanical repairs. This is where we started and this is where we continue to excel. A support team consisting of mechanical, balancing and electronics departments also means that we are to complete all repairs under one roof and this level of control lets us ensure that only the very highest standards are applied throughout all processes.

Rewinds & J. Windsor – Not Just a Mechanical Repairs Company

At RJW our focus has traditionally been on ensuring that the electrical and mechanical repairs side of our business continued to thrive and that we continued as market leaders in this industry. However, having access to a work force filled to the seams with such talent and experience and as we have has opened the doors to offering manufacturing and new product sales to enable us to help even more customers.

On top of our manufacturing and sales expertise our mechanical repairs experience also puts us in the perfect position to be able to offer site maintenance services to ensure that all necessary preventive maintenance tasks are carried out to ensure site reliability for our customers.
