Bathroom Fitting- 7 Jul 2026
This guy don’t know what he doing. Didn’t know the job and no proper knowledge about the work. When he couldn’t do it sold us to another crook. The other person didn’t do work properly and left the bathroom unfunctional after three months. Very bad experience and they took more money when they buy materials. Its disaster

Bricklaying- 6 Jun 2026
Absolutely fantastic service from start to finish! The team demolished our fallen garage and built a brand-new one to an excellent standard. Communication was brilliant throughout the entire process, keeping us informed every step of the way, and the turnaround time was much quicker than we expected. Everyone we dealt with was friendly, professional, and always happy to answer any questions. The workmanship is outstanding, and we're extremely pleased with the finished result. I wouldn't hesitate to recommend them to anyone looking for a reliable and professional company. A big thank you to Teresa, Jason and the team. Thank you for a job well done!

What to ask a East London extension builder before hiring?

Before hiring an extension builder in East London or extension building company in East London, 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 East London?

An extension builder in East London 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 East London 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 East London?

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 East London extension builder’s ability to deliver a result that meets your expectations.
