Extensions- 23 Feb 2020
We hired Arra brickwork to complete what looked like a straight forward side extension, this soon became very complex due to the angle of the build and the roofing. Whilst we had our own expectations, Aushra was very helpful in presenting more ideas and suggestions in line with what we wanted. She even went as far as building sample model to show us what the build would look like. We found Arra brickwork - Aushra and Authur to be genuinely nice people, they are very polite and very tidy workers and put in so much effort to complete the build, even when we didnt expect them they were there working hard. We had full visibility of spend as Aushra was prompt at letting us know how much materials would cost including the initial quote for the build which was reasonably compared to what we had previously been quoted. We could not ask for a more trustworthy team of builders who cares about what they do and I will not hesitate to hire Arra Brickwork again for any more projects.

Landscaping- 5 Aug 2026
I messed Eden around as I couldn’t make up my mind for what kind of border what I wanted. But Eden went out of his way to give me alternatives and visited me multiple times to give more ideas and suggestions. Came middle of 3 quotes originally, then he managed to drop the quote even further after his suggestions. Fantastic young man, may he continue his great work and become more successful.

Hard Flooring- 23 Feb 2020
Andrei provides great communication and very professional service. He was very flexible and worked extremely hard to get all the work done in the shortest time possible, but he did not compromise on quality. He worked very efficiently and considering all the work he had to do, he still left the house clean and tidy. The attention to detail was second to none. I’m extremely happy with my new flooring and would definitely recommend.

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

What to ask a Grays extension builder before hiring?

Before hiring an extension builder in Grays or extension building company in Grays, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Grays?

An extension builder in Grays 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 Grays 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 Grays?

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