Restoration & Refurbishment- 26 Jun 2022
Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new. The flooring is perfect both in the hall and staircase, and the walls are now perfectly smooth and painted immaculately. Friendly and accommodating, we will be hiring again for more jobs in the future, undoubtedly. Thank you.

What to ask a Dartford extension builder before hiring?

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

An extension builder in Dartford 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 Dartford 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 Dartford?

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 Dartford 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 Dartford 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.
