Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work

Extensions- 17 Aug 2021
Long overdue feedback, the pictures/ decor has changed since below but just wanted to share the feedback. Crew are super, we’re with us through pandemic and worked tirelessly when materials were short and jobs were delayed.. simon is a fair guy, busy but still gives you time to share his creative side. Nothing was too much of a bother. Workmanship is A* and I have huge OCD. I would recommend Simon and team to anyone. And we spent a fair amount of money, everything was reasonable priced with no surprises. With Covid, the whole team were mindful and with a short delay due to restrictions got back on track.. every single one of the team were nice/ hard working and rarely do you find a team that can do the demolition yet have the finesse of the final touches. Sorry for the delay in feedback..

Extensions- 22 Dec 2025
We contracted JMD for a detached house project to demolish an old 1970s extension & rebuild larger 70sqm extension, an outside terrace patio and remodel some of our internal ground floor setup. Project started in Feb2025 and JMD made super quick progress on the build during the dry spring months. We had to pause JMD due to our timelines which they were fine with and finally completed end-to-end by Oct2025. What makes JMD standout for us was their team of employees – they don’t use too many contractors, most of their team are employed by JMD and are a loyal hardworking professional squad. Liam, Mark, Chip, Ross, Zac and the rest – all top class! We had some additional projects and requirements mid-project, JMD provided good pricing along the way which were all totally fair and priced as incremental add-ons. YES – there are always bits that could be better, but JMD did an excellent job on the whole. Site left clean, tidy, complete and all post project snags dealt with! THANKS JMD!

What to ask a Gatwick extension builder before hiring?

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

An extension builder in Gatwick 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 Gatwick 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 Gatwick?

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