Plastering- 23 Dec 2016
Denis did a good job plastering and retiling a small area of my kitchen. He responded to my ad promtly, came round the next day to quote and carried out the work 2 days later as requested. He was professional, polite and left my kitchen clean and tidy after the work was done. I'm happy to recommend him and would contact him again if needs be.

Carpentry- 30 Oct 2026
Navid and partner built staircase with steps overriding each other so half of foot was under each step. Sent them photos to show them how stairs were supposed to turn on the corner and came following day to see that they had made platform smaller so too small to put post for handrail , raised platform so that head height was now too low, none of the stairs were level and stairs were shaking when trying to walk up them. They levelled, strengthened a little and agreed to putting in corner steps as it should have been in first place after taking a further payment then disappeared without putting anything right, doing any finishing or fitting railings They are not tradesmen, and have no idea about building regulations Their work is shoddy. They haven’t got proper tools to even cut a piece of wood straight without splintering and they have no idea of finishing. Do not believe previous reviews are legit

What to ask a South Croydon extension builder before hiring?

Before hiring an extension builder in South Croydon or extension building company in South Croydon, 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 South Croydon?

An extension builder in South Croydon 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 South Croydon 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 South Croydon?

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 South Croydon 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 South Croydon 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.
