Gareth and his team were amazing and professional throughout. He was very knowledgable regarding the options available to us. All work was completed quickly and efficiently. Gareth kept in contact with us throughout our garage renovation and even kept in touch afterwards to check everything was ok for the fitment of the garage door. I wouldn’t hesitate to recommend Gareth and his team and would definitely use them again for any future building work on my home. Great job completed.

AVOID AT ALL COSTS I can't recommend Tom. Previously TH&Jones Ltd he has changed the company name. He has left us with an extension that doesn't meet building regulations and needs to be taken down. Our house unsalable. I have an independent report to support it. Insufficient foundation, no damp course, insufficient insulation, incorrect installation of roof. He said he would rectify if we paid for 'things unquoted' but failed to show exactly what. We haven't heard from him in months. Stay away!!

Hi, my name is Wojtek. I am from Poland and have been working in the construction industry for 20 years. I graduated from a construction school in Poland. I’ve been living in England for 11 years, where I’ve gained extensive knowledge of building materials, principles, and types of construction work. I mainly focus on general construction, but my specialty is complete bathroom renovations — from total demolition to final finishing (plastering, drywall installation, floor screeding, plumbing, minor electrical work, ceramic and porcelain tiling, bathroom installations, painting). I am also a professional in insulating external walls with polystyrene, mesh, and various types of plaster (mineral, acrylic, silicate). Similar to bathroom renovations, I am an expert in insulation as well. I have extensive experience in Poland and am gaining more practice in England, though this type of work is still less common here. So far, I have completed several full home renovations. As mentioned, I have no issues with painting (using a paint sprayer), plastering, radiator replacements or repositioning, minor electrical work (the only thing I don't do is laying carpets). Depending on the type and scale of the job, I can adjust the number of people needed to complete the project if necessary. Thanks to my vast experience, I can assist with any type of renovation and ensure it meets high standards. I guarantee full dedication to every project.

Newman plastering.  I am a one man band company, with just myself on the tools This means I have no overheads, so I am able to keep the cost down for my clients, but if needs be I can lay my hands on quality plasterers who share the same skill and passion for the job as me. range of services cover: * skimming plastering * Damproofing * External rendering * Dry lining * Internal rendering * Monocouche scratched renders(k rend) Why choose me? * friendly & reliable service * Many years of experience * Pay attention to health & safety * clean & tidy I have more than 10 years experience in all aspects of the plastering trade, and started learning the art of plastering with my uncle . By the time I was ready to leave school I was already becoming handy with the trowel and had some experience behind me, so I went on to do my apprenticeship and work with various other plasterers gaining more experience and learning my trade on housing sites and various  big commercial jobs, as well as doing the odd domestic and private jobs. What makes me different from most companies? Well, I actually enjoy what I do and love plastering, so you can be sure to get a top job. So now you know a bit about me, feel free to use me for your plastering needs.
