Customer feedback
What customers say about AJK Building Ltd
Full customer reviews with names and project details.
I had a very positive experience with this company. From the first enquiry through to completion, communication was clear, prompt and professional. They kept me updated on timings, explained the work in straightforward terms, and completed the job efficiently and to a high standard. The team were polite, tidy and respectful of my property. I’m very happy with the service and would confidently recommend them to others.
Antony took on this project from scratch. He demolished an old shed then after listening to what we wanted, planned and built the new one. We are delighted with the result. He is reliable, turns up on time, adapts when we want to add things in and makes relevant suggestions. We would use his services again without hesitation.
Antony did our new garden decking. From start to finish he was thoroughly professional, and the quality of work was very impressive, with good pricing and great workmanship. He and his team got on with the work as planned with no hassle or disturbances whatsoever. They cleared and cleaned everything at the end and nothing was left unattended. I would highly recommend Antony to anyone looking for quality work at a sensible price.
I cannot praise Antony and Jack highly enough. I have never come across workmen who were so polite, professional and thorough. Work was tidied up every day and nothing took place without consulting me. The quality of the workmanship is second to none and already neighbours, friends and family have asked me for their number so they too can benefit from such great workmen. They went out of their way to ensure I was 100% satisfied and often went above and beyond, at their own expense, to ensure a fantastic job. They worked through extreme weather conditions including rain and snow at minus 4 degrees C.
The job started out as getting a new foundation and having an old porch removed. Following initial discussion and quote I decided to demolish myself, which was not a problem for Antony. Originally I was going to do all the brickwork myself, but asked Antony to come back and build up to damp-proof course so that he could finish the slab for us. This was not a problem. The work itself was done fast and to a high standard. Antony and his team were all very friendly and gave us tips on bits to look at for the project we are doing ourselves, which was great.
