Bathroom Fitting- 14 Aug 2021
I would definitely recommend Step-Up Contractors - they have done a really fantastic and great quality job of refurbishing our bathroom and ensuite shower room. They were very professional, friendly and communicated really well with us throughout the whole process. They tidied up every evening before they left and were very considerate. They did such a good job that we have asked them to come back soon to complete kitchen flooring work for us!

Chris hung a number of prefabricated doors and door frames that needed adjusting. He promptly provided us with a detailed quote and his availability. He did a job on a Saturday which was great as we really need this job to be done as soon as possible. The job was completed quickly, the adjustment to the doors are practically not noticeable and the doors and frames look great. Chris and his helper were very helpful and did a great job for us. Will definitely us Chris's services again.

What to ask a Longfield extension builder before hiring?

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

An extension builder in Longfield 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 Longfield 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 Longfield?

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 Longfield 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 Longfield 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.
