Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.

Latest review:
We recently completed a first and second floor renovation alongside an 5x6m extension of our 1930s property with Maxcontractorsint.ltd , and we couldn’t be happier with the results. From start to finish, they have been absolutely fantastic. The attention to detail and the quality of workmanship throughout the project has been exceptional. Matt and his team are incredible, they worked efficiently, kept work on track, and made sure we were updated and involved at every stage. Their skills, ideas, and collaborative approach truly brought the whole project together. Communication throughout the project was good, and the team provided great pre and post project support. Matt was very detail-oriented, offered inspiration during site visits, and was supportive of our requests along the way. We’re so happy with the end result and would absolutely recommend Maxcontractorsint.ltd for any project.

What to ask a Hatfield extension builder before hiring?

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

An extension builder in Hatfield 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 Hatfield 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 Hatfield?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Hatfield extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
