Bricklaying- 10 Jun 2020
We hired Jamie to take out a window and install a door. He was very polite, gave a good quote and timescales etc. He understood exactly what we wanted, visited a few times before starting to ensure measurements were exact and that small details that we requested were agreed and clear. Before he started we asked him to quote for another job and he completed both within the timescales given, plus he was clear about what would happen on what day, and stuck to it. Nothing was too much trouble, he is very courteous, his workforce too. He's understanding, responsive to contact, and an excellent job done as well as being very clean and tidy. We are already looking to have him do the next works we need to get in the pipeline! We would not hesitate to recommend him.

What to ask a Eastleigh extension builder before hiring?

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

An extension builder in Eastleigh 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 Eastleigh 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 Eastleigh?

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 Eastleigh 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 Eastleigh 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.
