Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.

Bathroom Fitting- 10 Jun 2026
I can't praise Cuban and Max enough. It's always a worry when looking for skilled tradespeople as you are putting trust in someone you don't know. My first meeting with Cuban filled me with confidence that he would do an excellent job which is why we chose him to renovate our bathroom. Paula was always available to answer questions and give advice on buying all the right fixtures and fittings to ensure the project ran smoothly. Cuban and Max were always punctual, respectful, polite and you can tell they have pride in what they do by the outstanding quality of their workmanship. Attention to detail is exceptional, and they both went above and beyond to transform our bathroom to something I thought we could only dream of having. I can highly recommend them for their professionalism and outstanding quality of work and finish.

Extensions- 13 Feb 2025
Shami and his team had been fantastic from start to finish! Before hiring his team he showed me around a house his team built, which was amazing to see. His communication was excellent throughout the progress of my renovation and very reassuring. Even as I had made changes to the build, he was very helpful in planning and adjusting to my needs. His team had built a single floor rear extension, including a new kitchen, bathroom suite, full electric rewire and plumbing from scratch. Also, comparing his team with six other builders, he had one of the most competitive quotes for the build. Post finishing the job, any issues I had were resolved immediately putting me at ease! I would definitely hire Shami and his team for any future jobs.

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

An extension builder in Dagenham 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?

What experience do you have with similar extensions in Dagenham?

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