Very happy with the work from Ernest. Nothing was too much trouble, and any issues along the way he just sorted. The team worked extremely hard and were all polite. I’d really recommend working with Ernest and his team and will be using him again for sure.

Extensions- 13 Jan 2019
George was excellent throughout - would highly recommend. Although I did not hire George to complete the whole job (as someone in my family is a bricklayer) he was instrumental in completing the build. A few points to demonstrate: - Fair and transparent quote (which was stuck to); - Flexible throughout delays caused by me (planning, etc.); - Supportive (advice on what he would do if he was running whole job); - Professional (including team). I will use him again.

I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

We recently had a loft extension completed along with wooden flooring throughout the house, underfloor heating installation, and a full silicone render — and we couldn’t be happier with the results! The team were an absolute pleasure to work with from start to finish. Their innovative and creative thinking really set them apart — they found smart solutions to challenges and helped us maximise space and style in ways we hadn’t even considered. What impressed us most was their attention to detail and how clean and tidy they kept the site throughout the project. It made a huge difference knowing the work was being done to such a high standard, without the usual mess and disruption. Whether it was a small detail or a big task, nothing was ever too much trouble. No job was too big or small — they approached everything with the same level of care and professionalism. If you’re looking for a reliable, forward-thinking team who take real pride in their work, I couldn’t recommend them more highly!

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

An extension builder in Crystal Palace 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?

What experience do you have with similar extensions in Crystal Palace?

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 Crystal Palace extension builder’s ability to deliver a result that meets your expectations.
