Loft Conversion- 5 May 2017
Artjom and his team have done a wonerful job on our loft conversion and house renovation. We are very pleased at the transformation. Although not the cheapest quote we obtained, they were highly professional, kept the noise down and cleaned up after themselves. We also added several other jobs to our initial quote and they undertook these as requested. It is important to keep a record of everything you ask to be done. They worked very fast and were able to complete everything within 2 months - it helped that our house was empty at the time, so they didn't have to deal with us living there at the same time as the works were being carried out. Overall, I would highly recommend Adam Renovations for any building works you need done to your property.

Extensions- 23 May 2022
Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

Conversions - General- 6 Apr 2010
After being let down by our previous builder, shortly before work was due to start, we were informed about this website, and somewhat hesitantly posted our garage conversion and kitchen renovation onto the site. After obtaining quotes from 3 builders, we decided to hire Nick cos of his straightforward and honest attitude to the job. We spoke with a couple of people that Nick had previously done work for, and they were very complimentary, so this just confirmed our decision to hire Nick. We have never undertaken any extensive building work before and were therefore nervous about the work starting, however I can honestly say that Nick was absolutely fantastic from start to finish of the project. Nick and his team were extremely hard working (finished much sooner than we expected), they kept the house as clean as possible when completing such works, and were generally an absolute pleasure to have around the house. Nick's craftmanship is exemplary and was always there to discuss any changes, extras or cut backs when not required. I would not hesitate in recommending Nick to anyone, safe in the knowledge that I know he would do an exceptional job, in fact more than three people have already asked for his details upon seeing the great job that he has completed here!! Thanks Nick for everything!!

Tiling- 6 Oct 2022
We are beyond shocked and disgusted by his awful behaviour. Initially, he acted professional and trustworthy, but he turned out to be exactly the opposite. On the 8th of July, he promised "3-5 working days" instead he pulled us along for two months of unbearable stress and waste of time because he kept on taking other jobs instead of doing ours. He wasted all of July as we had to meet him four times to finalize the design that he kept on rejecting until we agreed on the easiest option for him. He dragged out removing tiles and levelling 10 steps all of August, working 6 hours in total and leaving a job that is so appalling that it needs to be completely redone. He postponed the tiles' order for a month despite assuring us all August that he had done it in July; after numerous complaints, he sent the tiles' invoice, dated 31st of August. He gave us dozens of appointments but never came nor had the decency to cancel, despite dozens of calls, emails and texts, causing significant disruptions and loss to our life and work commitments. We asked him to reimburse the cost of the tiles and materials he didn't provide and for the work he didn't do, but he ignored our emails. We have removed him from the job and are reporting him to the relevant authorities.

Extensions- 3 Sep 2013
Kel and his team worked on my single storey extension with bifold doors and glass roof. He also did some landscaping in my garden, replacing the fencing and installing a raised patio with cedar battens to the side. Overall I was very pleased with the work Kel did. He is a good communicator and frequently visited the site to keep on top of the work. Kel was happy to discuss requests and was flexible with design changes. The bulk of the work was completed on time with just some minor snags remaining, but the finish is excellent. It's been a long and stressful journey, but it's been easier with the friendly support and professional approach Kel has taken to his job. I'd be happy to recommend Craft of London and provide a reference on request.

Demolition- 15 Jun 2024
Shane did an excellent job when he demolished an old unsightly concrete coal bunker. He obviously had all the right skills and the right tools and was happy to do a couple of small extra tasks. He gave some good advice about a separate maintenance issue that may well save me money. Communication was good and he arrived on time. Highly recommended.
