Bricklaying- 31 Oct 2019
Nic, did a super job. The finish detailing of the brick wall connections look great. He went above and beyond in regard to making sure he did what I wanted, each step of the way, and didn’t assume anything. He tidied up afterwards, helped with getting materials sorted, offered to drive unused materials back to the builders yard for me, turned up on time, and was pleasant and friendly to have around. I would highly recommend him to anyone.

Lee was great! 👍 He is professional and worked really hard to get the job done for us. He kept us up to date on progress and didn't grumble at all even though I changed the job 3 times. The wall looks 1st class now it's finished and I'm sure it's really strong and will stand the test of time :-) I would recommend Lee to anyone looking to get building work done and will definitely think of him first for the next job. Thanks again, I'm really pleased that you have made our garden safe again.

What to ask a Marlow extension builder before hiring?

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

An extension builder in Marlow 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 Marlow 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 Marlow?

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 Marlow 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 Marlow 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.
