Extensions- 19 Jan 2019
Alex and his team have done an incredible job with a keen attention to detail and have delivered a high quality finish. We have had a single storey extension, new utility and kitchen done, with some challenging structural work. Alex networked well with our architect and sourced a very professional engineer who tweeked our plans. He coordinated a team of builders who are professional, timely and hardworking. No gimmicks, or builders jargon about what stuff cost , just upfront honesty. The team was also acutely aware of the disruptive impact of the build on neighbours and ourselves and mitigated against that through resourcefulness. Alex is a problem solver which is what you want if you are busy with no time to micromanage. The big plus is that everying is done inhouse from structural work to electrics and plumbing. I cant speak more highly of reliable builders, we had to wait a few months for their availability but it was well worth it! Thanks

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

An extension builder in St Helens 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 St Helens?

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