Could not fault anything from start to finish. Ian and his team was on the job from the off ! Well organised with materials always there for each stage of the project and kept me fully informed of progress and happy to assist with extras that I added into the work. Was great to be able to carry on with my work and have trust in a company to just crack on with the project on hand. Would definitely use this company again should I need.

Restoration & Refurbishment- 25 Jun 2026
Ziggy has just done a huge piece of work for us over the past few months, decorating and refitting our kitchen, relocating a doorway, taking out a chimney breast, fitting a media wall, resizing and replacing windows and rendering our rear wall. Everything has been done to an outstanding standard. Ziggy takes great pride in his work and his reputation and is a real perfectionist. He’s communicated well all the way through and managed any anxieties we’ve had about such a big piece of work. He’s also provided advice when we’ve needed it. Ziggy’s really upfront about costs with no unexpected shocks. Ziggy was often supported by Darek. Both were always really respectful in our home. We needed someone we could trust and couldn’t be happier. We have future projects lined up and have no doubt we will use Ziggy again.

What to ask a Grays extension builder before hiring?

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

An extension builder in Grays 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 Grays 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 Grays?

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 Grays 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 Grays 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
