I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Plastering- 21 Sep 2026
John was quick to respond and came around promptly. Quoted quickly for a reasonable price, and commenced works the following week. Whilst I acknowledge that some of the walls were in very poor condition, there were some that were in very good condition with a decent, flat surface to render. The final result unfortunately was poor, appearing to be a rushed job rather than spending sufficient time ensuring it was completed properly and professionally. Lots of swirl marks in the render and plenty of gouges. Shame really, as the service and communication is otherwise on point.

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.
