Creativity and ideas aren’t things you always expect from a building team, but J Build were great at making positive suggestions.
I would highly recommend J Build, the firm was professional all the way from the initial quotation to the final touches.
If I had known having an extension was going to be as easy, I would have done it ages ago! Jan and his team were brilliant throughout.
We have done two major builds and if we had to do it again I would definitely use J Build. It seemed hassle free.
I would absolutely recommend J Build. They were incredibly hard working and the result is exceptional quality.
I honestly couldn’t be happier. There’s that moment when you move back into your house and it’s just as you would hope and more.
J Build think like us: They come highly recommended by our clients and have a passion about doing what they do and what they are good at. They have helped solve problems and looked ahead; appreciating what a beautiful space is being created and helping to make a unique place for our specialised Pilates Studio in the heart of Teddington. It is a pleasure to see people who are capable and adaptive, deservedly receiving the benefits such attributes bring.
We used J Build on a recommendation to build our kitchen diner extension and remodel our downstairs living space. We have been really impressed with Jan and his team and are delighted with the result! Having done several projects in the past, J build is by far the best company we have dealt with. The guys are courteous, tidy, extremely hard working and have delivered an excellent finish on time and on budget. Would highly recommend.
J Build have just very successfully renovated my crumbly, pokey, nasty bathroom into a beautiful 5 star resort-style bathroom. They also changed the boiler & water tank, absolutely seamlessly. They were brilliant from start to finish, not only was their work of impeccable standard, but their manners and etiquette were pristine.
The boys did a great job and were completely respectful at all times, which I really appreciated. There was even an electrician here still at 7:45pm! What’s the name of the little older guy? Mirek? He’s so cool. He was extremely diligent.
Their pricing is fair, I cannot recommend them highly enough. I will be using them when I do my large extension, knock through and more…. My only hesitation in leaving them a review, was my fear in them getting too busy for the next phase in my build! Many thanks to Rich, Jan, Mirek and the team.
I have a keen eye for detail and expect a high quality finish. The no-nonsense approach of Jan and the J Build team is just what we wanted from a building company and they are exactly the kind of people that we like doing business with. I had a good feeling about them right from the start of our build which I can only say is even better now that we have successfully reached the end. I would definitely recommend them to others and only want to use them for future projects. Cheers J Build, we are over the moon with the extension.
Jan and the team at J Build are great! They completed the project ahead of schedule, on budget and they exceeded my expectations. I would not hesitate using them again, thanks J Build!
J Build did everything they promised and more, they even managed to source some beautiful Oak parquet flooring for me for a great price. They are helpful, trustworthy and their finish is exceptional. I shall use them again for my next project as I know they will deliver to a high standard.
We were working to a very tight and strict deadline on our project and J Build finished on exactly the day that they said they would, amazing! They are the best company I have ever worked with and I highly recommend them.
Jon & Mandy
Nothing was too much trouble for Jan and his team, they are refreshingly helpful and delivered our build perfectly. We are planning to do more works in the near future and will definitely be asking them for another quote. We really appreciate all the hard work that they put in to give us the extension of our dreams.
Simon & Rachel
J Build are an absolute pleasure to work with. Jan kept coming up with new ideas to improve on the design of our building project which made the final layout work so well. We can’t thank you enough for all you help along the way and for finishing everything three weeks earlier than originally anticipated! We are really enjoying our new home and recommend J Build to anyone who needs work done.
I used J Build through recommendation so I knew they would be good but I was surprised by how good they really are. Nothing is too much trouble to them and their work ethic and attention to detail is second to none. If I ever need more building works done in the future, I know exactly who I’m going to call.
Nels & David
We saw J Build working on some projects nearby and having been invited into these properties by them to see their excellent finish, we were confident that they were a company who could deliver the desired results. It’s great that they provide the full design and build service, this took a lot of hassle and extra organising out of the process for us. When we got planning permission the building work began almost straight away, they definitely do not hang about and everything was completed to an extremely high standard before we knew it! We are so happy with the extension that we have recommended J Build to many of our friends.
I would just like to extend an invitation to Richard, Mirek and all at J Build to come and look at the finished extension to the property which you and your team have so kindly worked upon. We are very happy with the end result and have no issues in highly recommending your company to future clients who ask.
We are inviting any of your J build team who have worked on the project over for a drink and a bite to eat…. please extend our invite to Gregor and the others who worked through the rain and wind of the winter months doing the hard graft outside as they might like to see the finished project, and have lunch on us.
I had seen J Build working on a number of projects locally and their sites all looked very professional so I decided to give them a call to quote for my building project. The surveyor was very knowledgeable and provided me with a fully itemised cost breakdown. J Build invited me to speak with and visit some of their past clients and I was able to ask them how their projects went and see the results.
The building work was really good and all of their past customers gave great reviews, which filled me with confidence that J Build would deliver the goods. My finished project was even better than I had ever imagined and if I do anything else in the future I know exactly who I’m going to call… thanks J Build!
The quality of their work was excellent, down to the finish of the decorators. The aftercare is also excellent. It was a big job and there were a few things that needed attention afterwards. They always came round in a day or so and put things right without complaint. Jan was also great at suggesting changes to the build or décor to improve the outcome, which I appreciated – they didn’t just carry out instructions, they tried to improve them. One of the main reasons we went with them was time to complete. They gave the fastest time out of any of the quotes and they stuck to it – there were frequently 10 people on site. I found them to be reasonable when there was a need to negotiate on delivery or costs – it was always resolved amicably and to everyone’s satisfaction. They were always pleasant and professional.
I really love baking and did not have enough room in my old kitchen. Luckily my daughter is an Architect so she did some drawings for me and got planning permission to extend my bungalow. We knew of J Build through recommendation having previously done work for members of our family. After agreeing the details of the project they completed my build to an amazingly high standard. Now I have loads of space in my new kitchen and can bake away to my heart’s content, the first thing I did was make everyone at J Build some thank you goodies, I hope you enjoyed them!
I couldn’t speak more highly of J Build and had a good feeling about them straight after the first meeting with their surveyor. They gave me a clearly broken down and fully itemised quote, something that I was struggling to get from other builders and they even let me use their network of suppliers to source things like my kitchen and bathroom suite. The office support from J Build was amazing taking away the strain of having to make so many decisions and the builders were all lovely chaps who never stopped working. I would recommend J Build to anyone thinking of having work done, they really know what they are doing.
Angus & Caroline
As someone who works in the property industry I know how important it can be to get the right builder for the job. When things go well on a build all is great but if something goes wrong it can be a real nightmare. From the very start J Build’s surveyor filled me with confidence in the company by providing a level of detail and transparency that I could not get from any other builder. Following up on their references we also got nothing but good reviews about how well the process had gone for J Build’s previous customers. When it came to the actual build itself every single tradesman had the perfect work ethic and really took pride in what they did… they have certainly delivered the wow factor for our lovely new extension. Thanks to everyone at J Build that helped to make our plans a reality and in fact actually built us something better than we had ever hoped for! Angus.
Janice & Amal
We have had building works done before but no builder has ever delivered such a high quality service as J Build did, they were awesome! Right through the process nothing was ever too much trouble and they were keen to make clever suggestions all the way through to completion to enhance our home. If anyone asks me to recommend a builder I would not hesitate to put them forward… the experience was so enjoyable it was actually quite sad when all the works were complete and they left site giving us our home back as we missed them all immediately! J Build you really are the best! Thank you so much for everything, Janice and Amal.
I would like to say that I am delighted about how the house is looking thanks to all the hard work by the J Build team.
I really appreciate all the help from J Build in carrying out my project. You delivered exactly what you said and more, on budget and ahead of time… amazing!
Hi J Build, I’m extremely happy once again and will be giving glowing references to all your future clients. Thanks for all your help on my second building project with you and if I do a third I will be sure to be in touch!
Peter & Dermot
Thanks to everyone at J Build for your help with our extension project. We are very much enjoying our lovely new kitchen and will recommend your services to anyone considering building works.
Natalie & Mark
Hi there everyone at J Build. We really appreciate all the hard work that you put in to making our kitchen extension plans a reality. We’re spending so much more time now together as a family in the open-plan space which has been a breath of fresh air for us. Best regards to you all and we will definitely be recommending you to others!
Polly & Ross
We all love the work that you carried out at our home J Build. Even the Architect went speechless and then just said WOW when he saw the loft conversion after the scaffolding was removed. We will obviously be putting your name forward as a wonderful builder more than able to deliver the WOW factor!
These guys do not hang around or mess about! I thought that the actual build itself would be one of the most stressful parts of the process but I was wrong. Nothing was too difficult for J Build who made their own suggestions to the benefit of the finished article as things went along. I’m so glad I chose you to do my build and I will be recommending you.
Duncan & Philippa
Dear J Build, we know you came to us recommended but the level of craftsmanship and professionalism that you delivered in our building project was still a delightfully pleasant surprise. We’re chuffed to have chosen you to do our work and it goes without saying, we will be putting your name forward to anyone who is considering building works. Our sincere thanks to you all
I am so pleased that I found J Build online. When I started the process after buying my house I had nothing but a set of keys and some ideas. J Build helped me with everything: drawings, permissions, suppliers and more, providing a complete turnkey service. This was so useful to me, as I work a lot and do not have much time for anything, the fact that they held my hand throughout lifted such a weight from my shoulders. My heartfelt gratitude reaches out to the entire J Build team and I could not recommend this company higher
Simon & Anita
Brilliant builders, great service, that is what J Build are all about. I don’t know of a company out there who doesn’t advertise themselves in a positive light but to practice exactly what you preach is refreshingly honest and proves they are the real deal. Thanks for sharing your expertise with us along each step of our journey together and when I am asked if J Build performed well on my project all I have to do is tell the truth.
Dear J Build, I really appreciate all of your help completing my extension project so professionally. From the surveyor’s detailed quote to the conscientious foreman and the additional support from your office, I must say that you left me very satisfied and impressed with the service you provide. Thank you for making such a potentially stressful time such an absolute pleasure! My best regards, John.
New home is fantastic! J Build delivered a really good product, so thanks to you and the team.
Just thought I’d take the opportunity to thank you for all the hard work and effort you and your team have made, with regards to the extension at my parents’ home.
While we all appreciate that these things take time, the final result is outstanding and we wouldn’t hesitate to recommend you and the team for future projects.
I understand Mirek is assisting with the works in connection to the lift and the teams willingness to take on additional work, at what is a challenging time for my parents, is really very much appreciated.
If you ever want additional references, please don’t hesitate to contact me via my parents
Pierce & Sharon
We just wanted to follow up on our experience with J Build and in particular Marek and his team. We are so happy with everything that’s been done regarding the extension. The follow up care from Marek and his team has been amazing. All snagging completed very quickly and efficiently. There was very little snagging which to us shows the professional work ethic that Marek has.
Once again thank you so much and we would highly recommend JBuild to anyone that’s looking for building work.
Thank you for your very attentive support for our build, you have been very good to work with.
I wish J-Build all the best in the future.
