Groundwork & Foundations- 20 Jan 2026
AVOID. I wouldn't recommend Mj Brickwork. Micheal promised to get the job done in 10 days took a whole month. Only working Saturdays and Sundays on my job. Charging me for materials which I paid for upfront then using my builders materials which were kept in the house. Should have done a health and safety file which he hasn't. I asked him for a breakdown of materials and still not received anything. Also had a £200 Cctv survey done through Michael which wasn't worth the paper it was written on.They my plans which I paid a £1000 for. Nothing added up in the report. No details of who did the report either. I have sent him messages and called him many times but is totally ignoring me. He's reading my messages, so he knows im trying to get in touch with him. Pay the extra to someone else instead of hiring Micheal. If you're reading this Micheal be a man and call me so we can sort this out.

Kitchen Fitting- 4 May 2026
I am happy with my new kitchen, Simranjeet went above and beyond to carry out the works in a professional manner. If there was something I did not understand with the installation of the new kitchen, he would take his time and explain in detail what was the best method to carry out the job. He pays attention to detail, is very precise and neat, and will finish the job to his own satisfaction, as well as mine, which is a good trait to have in builders. Along, with my new kitchen, I also had floor tiling work done in the hallway, dining room and lounge. My extended family have seen the works Simranjeet has done in my house, and have approached him to do works in their own houses. I would highly recommend this Company, he is genuine and reliable, and I definitely will be getting more work done in the near future.

Full renovation with side extension, including: drainage/foundations, internal and external walls, main & flat roofs, windows, full bathroom & kitchen fit and landscaping front/back gardens. I don't normally write reviews but I felt obligated to because I have finally found a trustworthy and reliable builder with outstanding workmanship! I have been let down and taken advantage of by builders before but I can not recommend Sanj and his team highly enough. Sanj managed the project from start to finish, he liaised with the architect, local planning and Building Control as well as sourcing all the materials to ensure all the works were completed on time and to standard. It meant I didn't need to be "hands on" or give up any of my time. Sanj and his team were always punctual and never left our job for another until it was finished which meant the build was completed on time and to the agreed reasonable quote. Sanj and his team were always friendly and polite and always made time for use if we had any questions. Thanks again to Sanj and his team.

I am so happy that I chose Aaron to build my front porch. From the initial quotation visit through to the completion of the project, Aaron was professional, reliable, and approachable. He was always happy to answer any questions and gave me complete confidence that the work would be carried out to the highest standard. Throughout the project, Aaron remained punctual, hardworking, and professional. The finished porch has been completed to an exceptional standard using high-quality materials, and the attention to detail is evident throughout.

Absolutely brilliant work. Managed to fit us in after being let down by someone else. Extremely professional and on time, was very considerate of noise levels considering I work nights. Done the job to perfection and left everywhere tidy once finished. Would highly recommend Shane and most definitely use him again.

We originally got a different company for the extension works but started to realise there finishing wasn't great, that's when we got Viking in. Matt done a great job with the MDF panelling and also helped finish the structure, wish we got him from the start! Viking also had their own plumber Tim which we used and was more smooth under one company.

Plastering- 11 Nov 2013
Elite plasterer. That's the only way to put it. Richard did an amazing job at our house. The task was executed a perfection we didn't anticipate. His work has impressed any other building professional who came to our house for other tasks. I highly recommend Richard Kirk's services to anyone who is looking for a very high standard work. Beside his plastering skills, Richard is also very easy going and sympathetic professional to work with. My only regret is that he didn't have time to complete other tasks as he was fully booked. We're looking forward to re-hire him again very soon hopefully.

The S3 boys were wonderful. They managed to maximise the function in what is a small space as they knew the room was for my elderly mother. They were courteous, polite, reliable and fun. The room is beautiful and I would definitely seek their help with any future building projects. Thank you S3 (Uk) boys!

What to ask a West Midlands extension builder before hiring?

Before hiring an extension builder in West Midlands or extension building company in West Midlands, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in West Midlands?

An extension builder in West Midlands should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your West Midlands extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in West Midlands?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the West Midlands extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most West Midlands extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
