Extensions- 24 Oct 2025
Whilst we didn’t go ahead with Dave and his team (only due to proceeding with a family known builder), I only have great things to say about Dave. He was brilliant from the start in responding to my job post, arranging an appointment and spending a good amount of time talking over my ideas. He was really impressive with his knowledge, advice and expertise throughout his visit and staying in touch after. I cannot speak highly enough of Dave - if you’re thinking about having an extension or renovation - do not think twice about getting in touch with him.

Hard Flooring- 26 Apr 2026
Radek did a great professional job for us. Him and his colleague were really polite, and finished the job to a high standard at a very reasonable cost. He provided a thorough breakdown of the cost of the job, material etc which made the process very transparent. They showed up on time, worked quickly and efficiently, and cleaned up thoroughly after. I couldn’t recommend him enough and will be having him back to do more work on our house.

What to ask a Essex extension builder before hiring?

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

An extension builder in Essex 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 Essex 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 Essex?

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 Essex 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 Essex 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.
