Extensions- 6 Jan 2023
I am doing a double storey L shaped extension and the experience has been great so far. Vascontractors have been open, transparent, clear in communication. Have always understood the customer need. The quality of workmanship seen so far has been great be it building work, tiling, joinery or painting. Always provided a detailed timeline and schedule about the work. They even put extra hours and days for us to move back home. Everyday after work they tidy up. Even neighbours have given good feedback that they are unlike other builders who make lot of noise. Those minor things really matter when it comes to big jobs. They are fully committed to the job. I would highly recommend Vascontractors to anyone looking for big/small builds and making it a joyful experience for them.

Extensions- 17 Aug 2026
I had a very poor experience with this contractor and would strongly advise potential customers to be cautious before paying substantial sums in advance. I paid £3,672 by bank transfer following an invoice for the supply of structural steelwork. There were significant delays and communication issues, and the steel was not supplied to me as agreed. After giving him opportunities and clear deadlines to resolve the situation, I terminated the agreement and had to make alternative arrangements to keep my project moving. Most concerningly, despite my requests, the £3,672 I paid has still not been refunded as of the date of this review, and I am now pursuing the matter formally. Based on my experience, I cannot recommend this contractor. I would advise anyone considering using his services to be extremely cautious about making advance payments. I will update this review if my £3,672 is returned.

What to ask a West Ham extension builder before hiring?

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

An extension builder in West Ham 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 West Ham 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 West Ham?

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