Anna was very professional in her job and very up and doing. Even though she had a little baby at the time of the work but that did not deter her from doing her work well and on time.

Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Kitchen Fitting- 20 Jun 2019
Really pleased with Slawek and his team and would defiantly recommend them after seeing a professional kitchen fit job which they did for me. They went extra mile to resolve some design issues during the fit, kept the work area clean and tidy and behaved in friendly, polite manner. Nice, reliable team charging very reasonable prices.

Extensions- 6 Aug 2024
Started very good and came cross professional. But did not finish the job despite receiving half of the money in advance demanding cash payment, he left the job incomplete because demanding money in advance and threaten to leave if we don’t pay them in advance despite the job is not done according to their own given schedule. I also found out they are doing few projects at the same time that’s why couldn’t complete on time.

Pawel and his team are great - got them in for a few things now, from damp repair, knocking through an internal brick wall, moving a fuse box, installing a wood floor. Always good workmanship, easy comms and decent value! Have recommended to a few friends who are equally pleased.

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.

Painting & Decorating- 24 Feb 2020
Quite literally the worst tradesman I have ever worked within 25 years as a property developer! He came and quoted to paint my house (a good price I must say), little did I know that this meant he would spray everything that he can see, not prepare the surfaces by sanding them down or protects things. This included door handles, hinges, radiators, alarms sensors, tiles and my own furniture and cooking utensils. First time I confronted him about this he said that we would clean everything, and we agreed to carry own. However, it became apparent that we was doing the same as previously discussed. have paid hi 66% of what was agreed, I quickly realised that the damaged he has caused was going to cost me far more and I told him to leave. The next day he turned up at my house with his wife demanding the balance which I refused to give him, they were both shouting outside my house, threatening to call the police. I eventually agreed to pay the 50% of what was left, just so that they would leave. However, even once he had confirmed writing his acceptance of this, he walks over to me and threatened me one final time, saying that he will take me to court etc, there is god and he will see to me! I advise to stay away from this person, better to pay a little more and work with professionals who don't agree with one thing and do another. He paints using a spray, which means you can not touch anything up and he quite literally paints everything he sees!!

Fully electrify a new rear, 2 storey side, porch extension and shed. Arek was always the first one on site, worked very professionally, interacted well with the other builders and was happy to accommodate minor changes to the project. He suggested improvements to the the lighting layout and configuration were taken aboard. I highly recommend him and I'll also be using him to change my house consumer unit in the coming weeks.

Extensions- 5 Sep 2019
One of the best builders I have ever worked with. PMB take great pride in the work they do and finish to a exceptional level (even better than a lot of premium and expensive builders in the industry). Colin's knowledge about all aspects of building work is unmatched and that shows in the end product that he and his team delivered for me. PMB did a full refurbishment & substantial extension (everything knocked down except 3 external walls) - ground floor ext, first floor ext, loft extension, full re-wire, plumbing, gas, UFH, walls, plastering, fitting, decorating etc. His prices are reasonable and he advised when unexpected costs come up so I could make a decision on what to do. I will definitely use him again.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.
