Extensions- 30 Dec 2021
Its been a pleasure having Albi and his team build our extenstion. Excellent job done (we had a 32 sq m extension for a new kitchen/dining room and the build was seamless). Good workmanship and genuinely easy to interact with. Albi kept to the timelines, offered good suggestions and delivered excellently. Albi and his team are reliable and provided a competitive fair price. They would be here early (7.30 - 5) 6 days a week and were a genuine pleasure to deal with. They were neat (even covering our drive with mdf panels to protect it from rubble) and then pressure washing it clean at the end. Works included Foundations Construction work Skylights Roof structure and roofing Windows/Bi fold door Exterior render Insulation Woodwork - doors, architraves, skirting Plumbing Electrics Plastering Paint Flooring (wood & tile) Tiling Installing kitchen

What to ask a St James extension builder before hiring?

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

An extension builder in St James 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 James 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 James?

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 James 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 James 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.
