Extensions- 22 May 2021
I was left in a mess by cowboy builders. I found Sukhvindsr Singh from mybuilders and then I had nothing to worry about. He completed the project with utmost responsibility from erecting heavy steals to all the way up to finish. I was amazed with the level of his skills and above all honesty. This was a massive 66sqm single storey extension and he put up structure, brickwork, fibreglass roof , underfloor heating , tiling,electric work . He even went beyond our agreement to do bits and pieces to make sure i donot get stressed out. I have given him another job in same property to do patio 88Sqm with porceline tiling. Feature wall prepared by him stood out . Highly recommended and i will be surprised if he does recieve similar feedback in his future jobs.

What to ask a Kennington extension builder before hiring?

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

An extension builder in Kennington 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 Kennington 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 Kennington?

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 Kennington 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 Kennington 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.
