His work is fantastic and I am overjoyed with everything"

"I can't recommend Justin and his team enough. They are a no-nonsense professional, trustworthy ard hard working team. Justin always communicated clearly to me. What struck me more than anything is that he never spoke down to me, which as a single female has been my experience with many builders in the past.

His work is fantastic and I am overjoyed with everything Justin and his team have achieved in my house. For me to put complete trust in a builder has been hard but with Justin, this was not difficult."

"We are amazed by the transformation of our cold, damp cellar into a cosy, usable new space."

Justin and his team were always professional, friendly and above all, hardworking and reliable. We were kept involved all the way through the conversion from planning, electrics, plumbing, building and joinery. We are amazed by the transformation of our cold, damp cellar into a cosy, usable new space.

Justin's company was an amazing find and I cannot recommend him enough.

"Justin and his amazing team have just recently completed a massive cellar conversion for me. I am so pleased with the end result and cannot thank him enough. Justin and his team worked tirelessly what a professional company. Justin was so helpful in every aspect of the project. He helped me choose the items for the ensuite and was always conscious of helping me save on cost. He even measured up and helped decide what type of furniture would fit in the space he had created. Nothing is too much trouble for him. At the end of every day, the workmen even sweep up the inevitable dust created in my house. Just goes to show how much he cares about you. Justin's company was an amazing find and cannot recommend him enough. Thank you to Justin and your dedicated loyal team!"

"Carried out exactly how we wanted it"

Justin converted our damp basement into a fabulous dry flat in January/February 2017. He managed the whole project from the damp proofing to utilities and building regs. Very happy with the work. Carried out exactly how we wanted it. Would definitely recommend them to anyone!

"I wouldn't hesitate to recommend JRM to anyone wanting this type of work carrying out."

We contacted Justin about our basement conversion after finding his company online. He came to look at our basement as it was, discuss what we wanted to achieve, and explained what he could do. He gave us a competitive quote for the work and arranged for us to see a previous job he’d carried out locally so we could check out the quality of his work. We decided to go ahead and the work started within a few months.

Our basement was originally partly blocked off and unusable, but Justin and his team essentially made the space into a whole new usable floor of the house. We gained a second reception room with new french doors looking into the garden, a utility room, and a bedroom with en-suite facilities.

The work was carried out to a high standard and we’re so pleased with the outcome. We hit a few unexpected issues on the way but Justin always found a way to resolve them. Him and his team worked hard to accommodate all our requests and I found them all polite friendly and professional. I wouldn't hesitate to recommend JRM to anyone wanting this type of work carrying out.

"From start to finish nothing was too much trouble"

We contacted Justin to convert our damp, smelly cellar into an extra room. The end result has surpassed our expectations. We now have a multi-purpose room which we can use for relaxing, watching TV, listening to music, a playroom for our grandchildren or a guest room with en-suite facilities. From start to finish, nothing was too much trouble even when we added a shower it wasn’t a problem.  Justin and his team worked really hard, always there when they said they would be and were all very polite, friendly and professional

“We will definitely use them again in the future”

JRM converted our cellar into an office space. They were the only company who gave us detailed advice and talked us through what the job would entail. We were exceptionally pleased with the work carried out and would not hesitate to recommend them. We will definitely use them in the future if we move to a property with an unconverted cellar. – Guy Thomas


“Left our property clean and tidy”

Justin, gave us honest advice of what work needed to be done to meet building regulations and a very reasonable quote, his team were very polite and professional and always left our property clean and tidy. I would highly recommend him to anyone who was considering have a cellar conversion done. – John Greening



“From our first appointment, JRM delivered us a friendly yet professional service. Our basement was converted from a dark storage cellar to a fantastic, bright living space. Mess was kept to a minimum and JRM kept us updated at all times making the conversion completely stress free. We love our new Conversion, which was completed to a high specification, not only has it opened up our living space but it has added value to our property. I would definitely recommend JRM, many thanks!” – Vicki Bailes (Bradford)


“Professional standard”

“I had JRM do my basement conversion and was really happy with the final result. They converted the whole area under my house and they also fitted the structural steels which allowed me to have two large rooms, a kitchen area, a wc and a store room. The work was done to a professional standard and completed within the original time scales. I would have no hesitation in recommending them” – Garry Speight (Halifax)


“I have recently had two major jobs carried out by Justin Malone of JRM. He has completed the conversion of a problematic damp cellar in my house and also and extensive new area of damp proofing. I have been delighted with the results of both jobs. They were carried out quickly and efficiently, and with a minimum of disruption. Even more important the work was carried out to a very high standard. It was very important to me also that I could leave the house to people who I could trust to let themselves in and out. For all these reasons I would not hesitate to recommend JRM, in fact it was me who suggested that I would be delighted to offer a recommendation. If you did require any further information JRM have my contact details, and I would be pleased to discuss any matter further.” – John L Thompson (Leeds)

“Entirely professional”

“The cellar of my house was a dank dark dingy place, which has now been transformed into a beautiful flat with kitchen, sitting room, bedroom and en suite bathroom. Justin Malone installed a pump to keep it dry, took down two walls to provide more space and dug out the space, which was full of dirt, for the bedroom and bathroom under the front of the house. Throughout he was entirely professional. He always came when he said he would, worked extremely hard, left things tidy and as clean as possible when he finished each evening, and I had no qualms at all about giving him a key and letting him get on with the job while I was out at work. I can thoroughly recommend Justin for any sort of cellar conversion, large or small.” – DR Margaret Faull OBE (Wakefield)


“Outstanding service & quality of work

JRM recently completed full refurbishment of our cellar. The cellar was an old coal cellar and split into 2 spaces. Justin arrived to quote for the work and explained the options available and suggested his recommendation. Justin came across as very enthusiastic. When work started every aspect was completed by him, his team or a someone within the relevant trades required (plumber, electrician ect etc). We didn’t have to worry about finding a tradesman to complete any work, all this was taken care of, removing some potential stress. The job seemed major to us, but probably straight forward for the experienced team. Steels were fitted to open to cellar into a large room, a small bathroom was installed. All work was finished within the time scales provided and to a high standard and promptly signed off by building control. I can’t fault Justin or his team. Punctual, polite, friendly, hard working and reliable. We’re considering our next project which would involve opening up the ground floor to an open plan kitchen. We had no hesitation approaching Justin and asking him to do this for us. All being well this will happen this summer. Justin has my contact details and if anyone would like to see before and after pictures, please feel free to request them. Tom & Laura – Halifax


“Cellar Conversion”

Justin and his team converted our damp, dingy cellar into a playroom, storage room and small study. This was a full refurbishment including structural work, tanking the cellar, plumbing, electrics, plastering etc. We are really pleased with the end result as it has turned a storage cellar into several light, usable and safe room. Justin offered suggestions and advice throughout the project to ensure that the end result exceeded our expectations. He and his team were very friendly and helpful and worked around accommodating our young family to ensure that disruption was minimised. At least one member of the team was on site everyday which meant that the conversion was completed in good time. The team also worked closely with a Building Inspector to ensure that the room met Building Regulations – this included fitting a fire escape and appropriate fire proof plasterboarding and a fire door. If we ever need any similar work doing we would definitely use JRM again and we would be happy to recommend them to others – Sharon


“Professional service. Great quality. Great price.

We chose JRM to convert our cellar into an office / recreational space. Through all stages of the project, JRM showed a genuine enthusiasm and explained clearly what was necessary to complete the work. We are exceptionally pleased with the quality and value of our new room and would not hesitate to recommend JRM.
