Hard Flooring- 7 Nov 2017
I hired Alin to install laminate flooring within a quick time frame. Alin was quick at replying and scheduling in a date. He gave good advice to suit our needs and worked fast and efficient. He has always been professional at my home. Alin got all the work done within one day which I was delighted with. We are very happy and confident in him so we have hired him back to do many other jobs in our home.

Bricklaying- 17 Jun 2022
Our brick garden wall was collapsing and I contacted Richard Fitzgerald for a quotation. I'd already had a few quotes from other builders, some of whom had told me I needed work doing that didn't need doing! I found Richard to be trustworthy. He provided a competitive quote. He managed to source bricks that matched the colour of the adjoining wall, gave us a detailed breakdown of the work he would do, and didn't ask for any payment in advance. He built a strong brick wall with a concrete support wall behind. The finished wall is excellent and we are very happy with the work he and his team have done. On finishing the work the premises were left clean and tidy. I am very happy to recommend him.

Extensions- 28 Jul 2017
Tony and his team recently completed a large ground floor extension. The guys were polite and courteous, on time every day, worked hard through the day and kept a clean and tidy site. Tony was very good at anticipating issues before they arose, making useful suggestions and giving us time to plan. We had a previous bad experience with a cowboy builder and Tony was especially sympathetic and understanding. Tony and his team were always transparent and upfront and very easy to work with. Tony was recommended by neighbours that he had worked for and we would also highly recommend him.

We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

What experience do you have with similar extensions in Kingsbury?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Kingsbury extension builder’s ability to deliver a result that meets your expectations.
