Restoration & Refurbishment- 1 Feb 2026
The WORST experience I have ever had with a tradesman. I would strongly advise others to stay clear. There was no schedule of works at any stage. Adrian failed to plan, failed to communicate agreed works, & did not even tell his own workforce what they were meant to be doing. There was no evidence of professional oversight or management, resulting in chaos & extreme delays. I was repeatedly misled. He stated that Building Control had been contacted & paid for; but when I contacted them directly they confirmed no application or payment had been made. He damaged my property & instructions were ignored. He was rude, aggressive & shouted at me in my own home, which I found intimidating as a woman. Neighbours also complained about his behaviour. Despite multiple extensions, the job was left unfinished with little communication. He caused significant stress & a serious loss of time & money. The matter is now being resolved through the courts. I would NOT recommend him under any circumstances

What to ask a Shadwell extension builder before hiring?

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

An extension builder in Shadwell 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 Shadwell 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 Shadwell?

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 Shadwell 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 Shadwell 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.
