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.

Howard, Martin and team are easy to work with and happy to discuss any questions or queries along the way.

James was professional from start to finish and did a brilliant job removing an interior structure wall - which ended up being a bit more challenging since we have a concrete house - and stabilised the wall with a steel girder. He offered a competitive price and clearly had a lot of experience. Would highly recommend to anyone needing any work done.

What to ask a Merseyside extension builder before hiring?

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

An extension builder in Merseyside 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 Merseyside 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 Merseyside?

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 Merseyside 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 Merseyside 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.
