Jerzy carried out several jobs for us. He has completely refitted our bathroom, he's rebuild a wall, laid front of house path, restored old front door, installed solid wall internal insulation, rebuild window frames, plastered a room and few other bits and pieces. He is extremely reliable and trustworthy. He's always been on time, works really hard and has always been honest about things and up front with any issues. Always consulted us for possible solutions. His work is to the highest standard and if I want a job done well, I always go to Jerzy.

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.

An extension builder in Clapton 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.

Your Clapton 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 Clapton?

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