Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

Bricklaying- 29 May 2026
Giani and his colleague repaired our wall beautifully for a reasonable price. He talked us through the issues that caused the wall to fail and explained what needed doing. He started the job the next morning arriving promptly and then went about the job with care and pride. I can whole heartedly recommend AGB Construction to anyone looking for builders with good communication, a sincere pride in their work and honest fair pricing.

We are extremely happy we chose to use Phil for our loft and extension design. Phil is professional, extremely accommodating and a pleasure to work with. He was always contactable, punctual and happy to spend a lot of time with us to discuss designs and the planning process. His design ideas were smart and he presented us with a number of workable options. We wouldn’t hesitate recommend Phil and would certainly use again for any architectural works.

Restoration & Refurbishment- 15 Oct 2025
Quick, efficient, takes pride in his work and charges a good, fair price based on some other quotes I received. Whilst it wasnt the original work I had requested, Sergio was flexible and came over to help with last minute work to remove some garden slabs and concrete for a heat pump base. Seeing his work and professionalism, I would definitely hire him again if needed. Some tradesmen on MyBuilder said it would be a huge job and quotes extortionate amounts - Sergio came at 12pm, tidied up as he went along and was done by 1.30pm. 1 man, no fuss, just decent, hard working and honest.

Kitchen Fitting- 23 Dec 2025
I recently had my kitchen fitted by O&J Constructions LTD, and I couldn’t be happier with the results. From start to finish, the job was carried out exactly as agreed, with clear communication and professionalism throughout. The attention to detail was excellent. Every cabinet, worktop, and fitting was installed neatly and securely. The project was completed on time and exactly as outlined in our agreement, with no hidden surprises. Ahmed was courteous, punctual, and kept the workspace tidy each day. My kitchen now looks fantastic and functions perfectly, making it a real centerpiece of my home. I would highly recommend O&J Constructions to anyone looking for a reliable and skilled professional for kitchen fitting. The whole experience was smooth and stress-free, and the final result exceeded my expectations.

Demolition- 24 Nov 2021
We employed A.V Structures for the building of an external wall around our property, the removal of a garage and the installation of railings and gates. Throughout the 4 week programme we could not have been happier with their work. Arrival was prompt, their pace of work displayed energy and purpose. They were mindful of us and our neighbours and made sure the area was left clean and tidy at the end of each days work.in addition the workmen were courteous and kept us fully informed. Alex, the owner of the company, kept in close contact with us to assure himself of our satisfaction. He came on site at intervals to check that all was going according to plan. We therefore felt completely confident that quality and outcomes were important to him. Employing A.V Structures was a decision we were pleased to have made. We would use them again without hesitation and recommend them highly to anyone considering similar work.
