Bricklaying- 11 May 2024
From start to finish Sion was very professional and very knowledgeable which was very helpful, in regard of how to repair and improve our garden patio. Sion replaced damaged bricks, created a new entrance to the patio and installed coping to the bricked wall. He also repointed the patio floor and added a new step.The finished result is of high standard and we love how it looks now. Sion worked tirelessly for two and a half days (in the heat ) and tidied up after, which we appreciated. We definitely recommend him and will definitely contact again. Diolch Sion

What to ask a Marianglas extension builder before hiring?

What qualifications and experience do you have as an extension builder in Marianglas?

An extension builder in Marianglas 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 Marianglas 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 Marianglas?

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 Marianglas 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 Marianglas 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.
