Restoration & Refurbishment- 27 Nov 2017
After a few teething problems and unclear plans from B&Q, Lee, Jacob and Artur did a very good job, not only with all the new plasterboarding, skimming, electrics, plumbing, joinery and all tiling, but also with the complete installation of our new kitchen as well. Multi-skilled tradesmen who were knowledgeable, punctual and committed to the job in hand. In the end we are happy with the finished kitchen. I would be happy to let them do further work in our house.

Excellent job from start to finish. Highly recommended. We couldn't have asked for more. From the moment Justin came to size up the job we could tell we were in capable and experienced hands. His price was fair. His preparation was meticulous. He took great care to understand our wishes and select materials to match the old stone of the house. When it came to the build we were very impressed by the workmanship of Justin and his team. Overall an excellent job. We would re-hire Justin again without a moment's hesitation.

What to ask a West Yorkshire extension builder before hiring?

Before hiring an extension builder in West Yorkshire or extension building company in West Yorkshire, 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 West Yorkshire?

An extension builder in West Yorkshire 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 West Yorkshire 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 West Yorkshire?

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 West Yorkshire 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 West Yorkshire 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.
