Extensions- 26 Aug 2021
SSS BROTHER, They worked incredibly hard to transform our house in a timely and efficient manner, all whilst being responsive to our concerns and preferences. The SSS BROTHER did a great job extending our kitchen and backroom to create a beautiful space that we love hosting family and friends in. The job was completed to a high standard and with good communication. Throughout the work, the workers were calm and knowledgeable and - importantly for us - helpful and offered their opinion of how the extension should be built.

What to ask a St Albans extension builder before hiring?

Before hiring an extension builder in St Albans or extension building company in St Albans, 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 St Albans?

An extension builder in St Albans 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 St Albans 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 St Albans?

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 St Albans 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 St Albans 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.
