Bricklaying- 25 May 2022
Top notch builders! We used Future Home Construction to build our large wrapround extension. They are a reliable family-owned company who showed up on time, worked hard, sometimes working 6 days a week including Bank Holidays. The team worked with great care and professionalism and were very informative, walking me through the process and offering me solutions to problems. We have been very impressed with the high standard of work carried out on our house and are delighted with the result. We would recommend Future Home Construction to anyone considering having work done to their house.

What to ask a Hatfield extension builder before hiring?

Before hiring an extension builder in Hatfield or extension building company in Hatfield, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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.
