I received quotes from numerous companies for a complete house renovation including a double story side/rear extension and single story kitchen extension to completely transform a property from an old 3 bed semi to a modern 4 bed. Paul from PMCS Joinery came out as scheduled and was quick to provide a comprehensive quote that was broken down and detailed so I was clear what was included/not included and it was transparent. The quote was competitive and as Paul had come highly recommend and I’d seen some of his work I went with them. A start date was agreed and work commenced on time. Paul managed the project ensuring all work was at a high standard, Paul was always on site. All trades he brought in were professional and quality. Paul and his teams joinery was exceptional, all his staff polite and courteous. Any extras or challenges Paul managed and talked me through any ideas, options and costs. The quote was honoured despite materials rising. I’ve recommended PMCS to many friends, neighbours and family. The house has been complete to a high standard and I’ve been pleased from start to finish and highly recommend them. Many of my neighbours also commented on the standard of the property and how professional they were. Thank you to PMCS joinery

Extensions- 5 Sep 2026
We are really pleased with the work carried out on our kitchen and laundry extension. From start to finish, Kevin was extremely helpful, approachable and professional. He always took the time to explain things clearly, answer our questions and make sure we understood what was happening at each stage. Nothing ever felt rushed, and we really appreciated the care and attention to detail. The whole team were polite, respectful and hardworking. They also kept everything tidy throughout the work, which made a big difference while we were living in the house during the build. We are very happy with the finished extension and would definitely recommend them to anyone looking for a reliable and professional building contractor.

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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
