Steven and his partner undertook a number of jobs around our house. Laying a new floor skimming the hall and stair way, putting up a stud wall and fitting double doors. All the work was carried out to high standard. Steven also put up with us chopping and changing the schedule. He also effectively problem solved a couple of issues that arose and offered cost effective solutions. I have no issue with wholeheartedly recommending Steven.

Groundwork & Foundations- 9 May 2026
I cannot recommend Richard at RCB highly enough! He recently completed the drainage and manhole for me and the experience was seamless from start to finish. He arrived exactly when he said he would, kept the job and the area incredibly tidy and the quality of the job and finish is outstanding. Its rare to find someone who takes this much pride in their trade. Professional, polite and fair pricing. I'll definitely will be using them again

Bricklaying- 22 Apr 2023
I engaged DLD to demolish an existing boundary wall and build a new one to a specification recommended by them. Both Danny and Ben work as a great team with a work ethic to match, working tirelessly in all weathers throughout. Nothing is too much trouble and they take pride in what they do.

Extensions- 9 Dec 2021
Great quality of work. Excellent communication and military timing; always arrived on time on the days he said (which was over a consistent period of time rather than coming off and on your project as some other builders do). I am a structural engineer and even with all of my snags, John dealt with it well and patiently with a solution being reached professionally. John completed my works 5 months ago and all items have been faultless without anything going wrong.

What to ask a Mirfield extension builder before hiring?

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

An extension builder in Mirfield 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 Mirfield 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 Mirfield?

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 Mirfield 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 Mirfield 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.
