Bathroom Fitting- 29 Apr 2023
Many thanks to Kris abd Kane on a job well done. Despite the very tight schedule, they completely refurbished our bathroom transforming it to a high-end (hotel standard) wet room. Kris's original quote was very competitive. There were extras, but these were very reasonable. Once the job was completed Kris actually came back to install 4 or 5 grab bars without additional cost. Kris, and Kane are both very easy to get on with; thoughtful and calm characters. I travelled abroad during the job; Kris contacted me regularly and responded promptly when I reached out to him. As with any job' there were glitches but Kris's solution focus approach ensured a good outcome. Hope to work with this company again.

What to ask a Carshalton extension builder before hiring?

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

An extension builder in Carshalton 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 Carshalton 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 Carshalton?

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 Carshalton 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 Carshalton 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.
