Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Extensions- 18 Nov 2020
Unfortunately, Stuart Helm did not even start the job let alone complete it! Each time Stuart Helm was supposed to start work on the porch, he contacted me with an excuse explaining why he couldn’t start the work. This occurred over several weeks and eventually, we mutually agreed he would not be doing the work and I would repost the job. Very disappointing and lots of time wasted.

What to ask a Southfields extension builder before hiring?

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

An extension builder in Southfields 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 Southfields 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 Southfields?

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 Southfields 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 Southfields 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.
