Extensions- 12 Feb 2026
Graham and his team did a fantastic job on our single story extension including a kitchen and bathroom. The team are friendly and skilled ensuring we were not without a kitchen for more than 2 weeks. We have a young family and work from home and Grahams team ensured we were able to continue working with minimal disruption. Graham provided great guidance on utilising our space effectively and coordinating all the various contractors on the job to completion. Graham’s team were so great that we extended the job to decking and landscaping which was a great price and high standard of work. Graham was also the only builder who provided a written itemised quote and was always on hand to meet periodically to ensure we were on track for the budget. We have an old house and every hurdle we faced Graham was on hand to provide options and guidance. Even after the job has finished he provided great aftercare. We can’t praise the work enough and would highly recommend Graham and his team.

Conservatories- 24 Jul 2025
I posted the required work for my conservatory roof and received interest from 11 companies. My conservatory is relatively big and a very odd shape. Out of the 11 companies, 4 would not undertake the work, 4 would only work on renovating the current roof, and 2 just didn’t take on board my request quoting something totally inappropriate. Scott came to view the job and was confident in being able to meet my requirements and expectations. He talked me through the work that would be involved and how he would achieve this. His openness, honesty, and guidance gave me the confidence to choose him to undertake the work. He arrived ahead of the scheduled date and got down to work straight away. He kept us informed every step of the way with what was happening, completing the work in the agreed timescales. Scott and his team did a quality, first-class job on the new roof, which I am extremely satisfied with. I cannot thank him enough for what he did and would wholeheartedly recommend him.

What to ask a Runcorn extension builder before hiring?

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

An extension builder in Runcorn 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 Runcorn 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 Runcorn?

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 Runcorn 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 Runcorn 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.
