What our clients say about JAM Builders Ltd.


Recommendations are how JAM Builders gets most of its work. We have built up a reputation over the years as a professional, and friendly company, who bring in all projects within budget and to the highest quality.

Coming from New Zealand where living spaces are large, we wanted to extract as much space as possible from our somewhat smaller London home. JAM helped us do this and more - from opening up the downstairs area with an open plan layout and conservatory, to space saving wall alcoves in the bathroom. JAM had all the good ideas, and they all came together to give us the space and
flow we wanted.
As for workmanship, its top-notch and JAM clearly takes pride in its product and people - and its testament to this that the JAM builders and subcontractors are all great to deal with and can't do enough to make sure you're happy with the result.
It was also refreshing to see the JAM owners play such an active part: Marlon's planning and project management was excellent, and he delivered an ever-changing brief bang on time. Jed worked his charm to make sure the job ran smoothly - so much so that three sets of neighbours want JAM to build for them! Last but not least, Jane's eye for design meant that we ended up with a lovely modern and fresh house with all the right fittings.
In short, the whole JAM team is excellent and you'd be mad to use anyone
~ Lee & Charlie Thompson. 

JAM was originally contracted by us to undertake the extension of a side return for a new conservatory, as well as the digging-out and tanking of our cellar in August 2009.

Jed and Marlon worked with our subcontractors and us in order to achieve the smoothest workflow possible and it is testament to them that they coped excellently with a very dynamic project environment. Jed and Marlon were always on hand to give advice and where necessary, offer alternative suggestions in order to get the job done as efficiently as possible.

Jed and his team were always on time, hardworking and fun to be around and there was always plenty of lively banter on site! They coped with a variety of requests for additional jobs to be done and kept within our agreed budgets and timescales, apart from one totally unforeseen modification to our cellar. The quality of the work has been nothing short of excellent and both my wife and I are delighted with the work that has been done.

It is rare to find tradesmen who operate in such a professional and courteous manner, stick to timescales and budget and ultimately produce such high-quality results. I can thoroughly recommend the JAM team in an environment where finding a quality firm is fraught with uncertainty. It is without question that you get what you pay for JAM were competitive, but on the basis of recommendations from a friend who had used JAM previously, we chose them over a cheaper quote and are very happy that we did so.

Thanks once again for a great job.

I was very pleased with the overall project management and final result. I've always felt at ease with the workers allocated to the project (carpenter, electrician and decorator) and they were happy to discuss changes to the original specs and give suggestions based on their expertise. The final result is great: the flat looks brand new. Also, the quotation process was very clear and professional. I would definitely contract JAM again.

JAM builders have now completed two jobs for me on my house in Hammersmith and I would highly recommend them. The jobs were completed on time and on budget and with a minimum of stress to myself the client. Marlon and Jed are very quick to understand requirements and are happy to pitch in with suggestions too. They use polite, friendly, tidy, skilled people to complete the work. It is very clear that Marlon and Jed are very particular about the quality of the people that they use on jobs and I believe that if they continue to do this they will continue to be successful. I look forward to working with JAM in the future.
