What a find! If you need a builder or tradesman then seriously look no further! Simon is the man for your job. Simon is incredibly professional, personable, trustworthy, hard working and skilled. I’m really not sure there is any task he can’t take on. He has converted our empty garage space - adding a side door, loft space and spot lights; plaster boarding, plastering and painting throughout. He did a brilliant job, kept to schedule, kept everything tidy and we’d have barely even known he was there. We have since had Simon back to complete works in the garden - laying a patio and gravel, installing a gate and other various tasks. Once again he’s done an incredible job. He’s extremely well priced particularly given the service he provides and he never goes over any agreed budgets. I have previously found it extremely difficult to find a tradesmen anywhere near this calibre and wouldn’t hesitate in recommending him.

Extensions- 20 Feb 2021
I've no hesitation in recommending Gold Bricklaying (Phil and Villius) for building work. They came in at a very competitive price and performed a superb job in the erection of a new porch. They were polite and courteous and worked tirelessly throughout the job to achieve an excellent result. Every requirement was met and the attention to detail was exemplary. Communication was excellent with quick responses which is so necessary when involved in a building project.

What to ask a Dereham extension builder before hiring?

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

An extension builder in Dereham 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 Dereham 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 Dereham?

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 Dereham 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 Dereham 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.
