Extensions- 3 May 2022
Dani and the team are friendly, professional and patient. They do the works to the best standard. I had a number of jobs as I renovated my entire house. I initially hired them to extend my kitchen. As I was happy with the job. Then, I hired them to renovate the bathroom, do the plastering, tiling the kitchen, etc. Dani is experienced in many building aspects. I did some jobs by myself, Dani shared his experience with me and also provided advice. I would highly recommend Rimini Construction. For any future works, Dani is the first person that I am going to get in touch with.

What to ask a Darwen extension builder before hiring?

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

An extension builder in Darwen 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 Darwen 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 Darwen?

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 Darwen 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 Darwen 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.
