Built4u Developments have been a pleasure to deal with throughout the entire process of building our new home in leeds. William and his team are extremely professional, friendly and genuine people. They are punctual, reliable and proved to truly care about the quality of work that they produce. William has always been available for any queries we have had about the building process, and has been transparent about each stage of of construction throughout. William is extremely skilled at what he does, no task proved too big for him or his team, especially after seeing our stone and brick feature wall he told us to leave with him, which is a truly remarkable piece of art that he has built, which i am over the moon with, He also came up with several innovative suggestions throughout the house build process in order to improve quality of works, he has been brilliant. I would highly recommend Built4u Developments ltd for any renovation work, new build or feature work - we are so pleased that we decided to go with them out of a long list of construction companies in West Yorkshire. Thank you William and Team for helping us achieve our beautiful family home :)

EEGL came out quickly to re-lay a collapsed front boundary wall. Fair quote, turned up when they said they would, and the finished wall is neat and solid clean pointing and properly matched to the existing brickwork. Very good brick layer. All neighbours said wall looked amazing. Tidied up afterwards and were easy to deal with throughout. Would happily use again. Using again for another wall.

Keiran did an excellent job for us, rebuilding a wall and pointing some brickwork. He contacted us promptly and came to quote the same day. He completed the job in one day - staying until 7 pm to get the job finished. The quality of work is excellent and he left everything clean and tidy. He may be young, but he has excellent work ethics and workmanship. Will be using him again and would have no hesitation in recommending him.

Extensions- 12 Feb 2025
From the first communication with Stewart this has been the most easy and amazing process.. I honestly can't praise him and his whole team enough. The process has run so incredibly smoothly and quickly it's been amazing. It's difficult choosing a builder and we worried we would choose the wrong one, worried about how it would go..but we choose the best option. I would highly recommend Chez Construction to anyone looking for builders. It's taken around 3/4 weeks give or take from start to finish. Stewart was always on the end of the phone to respond to any questions wr had and dealt with the architect and council for us aswell. We are very very happy with our new extension.

Mark and his team have done a great job on my old house, given the heat from our tropical weather I am very thankful as I'm sure most builders would have refused to work on some days, We are now looking forward to redecorating the bedroom and the new open plan kitchen/dinner, thank you Mark

What to ask a Castleford extension builder before hiring?

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

An extension builder in Castleford 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 Castleford 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 Castleford?

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 Castleford 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 Castleford 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.
