Restoration & Refurbishment- 8 Jul 2026
I give 1 star for their unprofessional roof inspection service. We fully confirmed the 10:00–11:30 site visit days ago and exchanged the full property address with mutual consent. Without advance warning, they sent an unexpected reconfirmation message at 6:57 on the appointment morning. My phone did not pop up instant alerts for this early text, so I only read it after driving 1.5 hours to wait at the house punctually as arranged. I waited on site for ages, yet no staff turned up. I made several phone calls to ask for their arrival time, but nobody picked up my calls. It is entirely unreasonable to double-check a fully locked-in booking at the last minute, ignore customer calls and leave clients stranded after a long drive. Their messy schedule management wasted my whole morning and travel hours, with no respect for customers’ pre-planned trips. I will never recommend this firm, as they cannot keep confirmed appointments and disregard phone enquiries from clients.

Extensions- 11 May 2022
Craig has recently completed a garage to kitchen extension with an added downstairs toilet and utility room. The whole process has been positive, Craig was confident in his quote and advise but was keen to listen to our ideas and was happy to discuss various options around budget and function etc. Craig's initial quote was agreed and didn't differ, although I appreciate building materials may have increased during completion, which made the whole project manageable and we weren't worried about hidden charges etc. I would highly recommend Craig and he also has great contacts within the industry for electrical, plumbing, roofing and windows / doors to ensure all jobs are completed to standard.

What to ask a Derby extension builder before hiring?

Before hiring an extension builder in Derby or extension building company in Derby, 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 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.
