Commercial Painting

Within our Commercial Department we have qualified and experienced Decorators who are capable of providing a top class finish to their decorating work. We have a varied list of clients from Local Authorities, Health Authorities, Government  Departments, Construction Companies, Property companies and local businesses.

The photographs provided show the various types of decorating we are capable of carrying out.

Intumescent Painting-

We can provide the customers with Fire Protection Intumescent Coating, which can provide from Half Hour up to two Hour Fire Protection Rating. We have recently completed large contracts in Birmingham and Bristol for certain blue chip companies.

Cladding Painting-

We are also equipped to carry out external cladding painting and repairs. The photographs provided show you the type of work on such contracts that we have successfully completed.

Industrial Cleaning-

J.J Williams Ltd has a specialised Cleaning Department, which carries out various forms of cleaning.

Work such as High Level Gantries and Steel work cleaning is carried out by a fully trained team of operatives. 


Our Rail Division has grown enormously over the past few years. We as a company are now Linked-Up Approved, and all our Rail Operatives are all PTS (Personnel Track Safety) trained. Therefore, we are well qualified to carry our any size contracts on any Rail Track in the UK.

Although we are a Welsh based, we are prepared to travel to any part of the UK to carry out such contracts.

We have successfully completed many contracts for various Construction Companies on Network Rail sites and recently a large contract on Rail Bridges in the centre of Cardiff.We have also carried out refurbishments of Main Line stations such as Gloucester, Cardiff, Swansea and Temple Meads, Bristol and many more.

We as a Company have built a strong and respected reputation for completing work on time and within budget, and therefore we have forged strong links with many of the Rail Contractors in the UK.
