Positive Experience with Craig and Team

We recently completed our extension project with CJ Smiths and overall had a positive experience.

Their pricing was reasonable compared to other quotes we received, and communication throughout the project was good. Craig was responsive, easy to contact, and always willing to discuss any questions or changes along the way, which made the whole process smoother.

One aspect we particularly appreciated was their support with a more complex part of the project. We had a bespoke cabinet with a fairly complicated sliding door system, and Craig and the team took the time to carefully study the manuals and work through the details with us. Thanks to their effort and patience, we were able to achieve the sliding doors exactly as we had envisioned.

The team worked hard for the project and were cooperative when adjustments were needed. We appreciated their willingness to address points raised during the build.

Overall, we are happy with the service provided and would be open to working with Craig and the team again in the future.

We used Craig to build our extension…

We used Craig to build our extension because we were recommended by our friends. His work and team are amazing. Very professional and the way they designed my media wall I couldn’t be happier. I would definitely recommend Craig to our friends and family. He will always try to help and find solutions throughout the process

Great Kitchen Renovation

We used Craig and his team for a complete kitchen renovation and are thrilled with the results. Both the process, the work and the finished results were all great. Craig and his crew are very dependable and makes what can be a stressful process feel very smooth. They are great at finding solutions and makes you really trust the process. We would highly recommend them.

CJ Smiths builders home renovation

CJ Smiths builders, done a fantastic job renovating my home, it needed a lot of hidden work, but it was discussed with me every step of the way and I was made to feel comfortable with any decision which were made. I cannot rate this company highly enough and would use thier services again and recommend them also.

Excellent builders, highly recommended

We are extremely happy with the work that Craig and the team have done for us. Throughout the build process communication was excellent and the project was delivered on time.

Craig's team were a pleasure to have around the house, very tidy and organised which meant there was limited disruption for our family. We had several unforeseen issues and due to Craig’s experience, he dealt with them really well, going above and beyond to get issues fixed.

I would have no hesitation recommending or using Craig again. He is someone you can trust and clearly enjoys and has a lot of pride in the work he does.

High quality, good communication.

Really pleased with the work done on our garden. We’d been messed around by another guy but Craig and his team came in, quickly got two patios laid and installed artificial grass for us. Communication was good, always kept us up to date. Quality of the finish is really nice and we now have a great space for our kids to use. They also did it for a really reasonable price given the state of the garden when they took over the job. Thanks to CJ Smith, would recommend.

Garage conversion

Craig completed a small garage conversion to home office for us Jan 2024.

When he came round to quote he was friendly and professional and gave some good advice.

Work was completed promptly and efficiently. It looks great and I would have no problems using Craig and his team again for future projects.

Exemplary Craftsmanship and Professionalism: A CJ Smith Building Experience

We had the pleasure of working with CJ Smith, and it was nothing short of a remarkable experience, thanks in no small part to the exceptional leadership of Craig Smith. His unwavering commitment to excellence, coupled with a keen eye for detail, truly set the tone for the entire project. Under Craig's guidance, the CJ Smith team showcased unparalleled professionalism, delivering a flawless extension above our garage. It's rare to find someone as dedicated and skilled as Craig Smith, making him the driving force behind the success of CJ Smith.

So impressed were we with their work that we've already lined them up for phases 2 and 3 of our project. This is a team that goes above and beyond, making them the epitome of excellence in the world of building.

Highly Recommend

Would highly Recommend CJ Smith’s, Craig and his team have now done 2 separate renovations for us. Both times the team have been professional and reliable, the work has always been done to a high standard and initial time frames given to complete the projects have always been upheld. We’re looking forward to using them again on our next project.

Highly recommended!

Craig was recommended to us by a neighbour and we were so pleased with his work. He was always responsive, on budget and on time.

Craig was referred to me from another friend. I found Craig and his team to be very professional, skilled and hard working. They even worked on a bank holiday to get the job done in time. Very impressed! Very good value for money spent.
