Loft Conversion- 14 Oct 2021
Zilvinas produced drawings promptly and at a very competitive rate. He attended several site visits and ensured to incorporate all of our ideas. We have received fantastic after sales service from GoldBerg Engineering throughout the project and would not have had the results we have, without Zilvinas. Goldberg Engineering has provided brilliant guidance throughout, through rapid response emailing, regular Skype and several site visits. Goldberg approved each work phase and continues to offer support. Thank you very much! Highly recommend, 5Star!

What to ask a Clapham extension builder before hiring?

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

An extension builder in Clapham 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 Clapham 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 Clapham?

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 Clapham 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 Clapham 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.
