Plumbing- 17 Mar 2026
I hired this handyman to install a new washing machine and fit several kitchen doors, and the results are absolutely flawless. The washing machine was set up quickly with no leaks or leveling issues, but the real highlight was the precision shown in aligning the kitchen doors—they are perfectly straight and have completely refreshed the look of the room. He arrived right on time, worked incredibly efficiently, and offered very fair pricing for such high-quality work. It is rare to find someone so versatile and detail-oriented, and I will definitely be booking him again for future home improvements.

Extensions- 18 Jul 2023
Very very happy to recommend - I fact, I already have to friends and family! Bob and Andy built a single storey utility room extension for me. To begin, the quotation process was easy, tho I already had got plans and approvals etc in place. The quote was competitive, and after the build was finished the final amount was exactly as quoted. They also put up with me making small alterations, without complaint! Reliable, competitive, polite and tidy, I would absolutely have no hesitation in asking them to do other building work should the situation arise. They were polite and friendly, happy to accommodate my working pattern, and I had no qualms about leaving them alone in my home. Am a very satisfied customer. If needed, I would be ok to show the work I've had done to prospective customers.

What to ask a Derby extension builder before hiring?

What qualifications and experience do you have as an extension builder in Derby?

An extension builder in Derby 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 Derby 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 Derby?

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 Derby 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 Derby 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.
