Latest review:
This was a whole house refurbishment involving a garage conversion to an office and a utility room and a doorway through to the main room. The whole of the downstairs was opened up removing walls and replacing with steel girders. This required further footings to be installed and vertical and cross beams to support the structure. Also removed a door and windows to install bi-folding doors. All then plastered and made good. Cavell employs a team of very friendly, happy and accommodating tradesmen and his overall aim is to make sure the customer is happy with the end result. He was also very accommodating and helpful when problems arose. I have since employed Cavell to do a whole refurbishment of a rental flat and several other minor works and repairs. We are now embarking on another whole house refurbishment which will involve a two storey extension and walls to be removed and steels installed. I would have no hesitation in recommending Orange Tree Construction.

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.

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.
