Landscaping- 17 Mar 2020
WOW!!!! Having previously being ripped off when having my patio laid and having to suffer increasing frustration and disappointment with it for over 9 years or so I finally caved in and looked to have it redone. Keith was a revelation. He listened to my tale of woe and asked pertinent and intelligent questions to understand what I actually wanted when he came to do the survey. The quote he produced was quick, detailed and presented me with options for the ideas I had in mind. It was also a very fair price for the work required and involved. He produced a contract which put my mind at ease somewhat and protected us both. He was punctual, honest, polite, knowledgeable and hard working. His work was to a really high standard and quality. Every day he left the site as clean and tidy as could be under the circumstances. He communicated well with us throughout ensuring we knew what he had done, what was still to be done and how and when he was going to do it. The final finished patio is fantastic, I love it. He started when he said he would and despite some vicious weather he finished ahead of schedule. If you want a great job for a fair price completed by an honest hard working grafter and tradesman then Keith is your man. So much so that he will be the only person I will approach to do any further works I may need in the future. I wouldn't hesitate to recommend him to anyone. Five star quality. Top Man

Michael was responsible for organising and overseeing my self build project, including the demolition of the old house and site preparation. The new detached house is approximately 5000 square ft over four floors including a basement. Michael's diligence, professionalism and reliability were exceptional. I have also used Michael on other small projects and have been equally impressed. Above all, i have found him very trustworthy. I would happily discuss the projects he has been involved with anyone considering offering Michael a project to carry out.

Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

Latest review:
We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

An extension builder in Bromley should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Bromley extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Bromley?

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 Bromley extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?
