Kitchen Fitting- 7 Jun 2020
We liked Alex from the first meeting and the first impression was spot on. Alex did an amazing job on our kitchen, which was half initiated by another tradesman. He reviewed the work and fixed many issues, always explaining and communicating well. Our kitchen had to be adapted and had some non standard cabinets but Alex was able to do all the additional features we asked for and with a great result. He also recommended some design changes which we agreed to and love. He finished the work, reviewed everything and signed off, always with a smile which is a plus. Definitely highly recommended and we will call him again in the future for sure. Thank you Alex!

What to ask a Stanmore extension builder before hiring?

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

An extension builder in Stanmore 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 Stanmore 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 Stanmore?

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 Stanmore extension builder’s ability to deliver a result that meets your expectations.

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.
