Rez and the Team have done an excellent job with the complete bathroom renovation and additional decorating works, laminate flooring in the hall and living room, along with plumbing and electric tasks. Very professional, with great communication and finished all works to a high standard within the estimated time, accommodating all changes as the works went. Very grateful also for tackling the bathroom wall tiles pattern, which turned out to be exactly as planned.

What to ask a Northwood extension builder before hiring?

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

An extension builder in Northwood 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 Northwood 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 Northwood?

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 Northwood 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 Northwood 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.
