What makes us different from other West London builders?
In 2019, we were awarded the Which Trusted Trader seal for builders and a Silver award with the Considerate Constructors Scheme (CCS).
Carrying out refurbishment work or a house extension can be an exciting and, at the same time, daunting experience. Our team aim to take away your stress by ensuring everything runs smoothly from start to finish.
We make the process clean and simple by providing realistic cost outlines, ensuring schedules of work are realistic, and we pull everything together to run like clockwork.
We are builders with NO hidden charges
JNJ is a Which? approved builder who you can trust to outline what all the costs are likely to be at the very start of your extension or renovation project.
If alterations are to be made to the original plan, there may be extra costs but only after agreeing these with the customer in advance.
We never skip on quality or cut corners. If required, we’ll work with you at finding ways to reduce costs if you think they’re too much and provide a revised quote that better suits your budget.
Our Three Quote Recommendation
We advise gathering at least three quotes from other West London builders for your extension or renovation project. JNJ can provide advice and a checklist to help you assess whether the quotes you’ve been given by other property developers include everything they should.
This checklist safeguards against builders leaving out key aspects of a job in order to keep costs down and make their quote appear more appealing.
The checklist will help you choose your building services company wisely by scrutinising the information you’ve gathered in order to assess the quotes on a ‘like for like’ basis. Only by doing a thorough comparison can you be clear about what’s included in your quote and what’s not.
