Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.

What to ask a Worthing extension builder before hiring?

Before hiring an extension builder in Worthing or extension building company in Worthing, 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 Worthing?

An extension builder in Worthing 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 Worthing 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 Worthing?

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 Worthing 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 Worthing 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.
