Testimonials

Loft extension

From day one, Justin and his team were able to offer us reassurance, guidance and ideas for what was a big project for us. Work was done slightly ahead of time, to budget and with the utmost consideration and minimal disruption. Justin's team went outside of their remit to deal with any issues we encountered and were more than willing to deal with any extras we threw their way. We wouldn't hesitate to recommend JNA Developments if you are lucky enough to grab them.

Single storey extension, removal of garage, fitting of a new kitchen and bathroom and new patio laid in garden.

Justin - and his team of half a dozen or so - were absolutely superb! They were courteous, friendly, reliable and competitively priced, The quality of work was outstanding, and they were a pleasure to have around! They all had a very nice manner - they were great with our kids - and dog - running around! The work was completed, as first advised, within three months - it was all done just before Christmas. We cannot recommend them enough - and will certainly be using them again for any other work we need in the future. Thanks ever so much! We are absolutely delighted with every aspect of the work! It has been a tremendous success.

I cannot speak highly enough about this company. They were with me for 4 months and during the whole time they were reliable, clean, friendly and explained everything. The standard of work is incredibly high. I would recommend them again and again.

Loft conversion creating a bedroom and en-suite and moving of walls on the ground floor creating two new rooms.

Justin was amazing, polite and easy going. Everybody involved in the work on the house were also very nice, polite and a pleasure to have around. The work was completed exactly on time with the minimum of fuss and disruption. Justin ensured the house was hoovered every evening before he left and it made what could have been a stressful experience a lot easier to bear. Even after the work was completed Justin came over to the house immediately when the carpet fitters needed doors trimmed to allow for the carpet thickness. I am very impressed with the standard of work and the amazing people that Justin and his workforce are. I would and have recommended them on to other people I know

Justin has to be the most pleasant builder I have ever met. He is helpful, experienced and caring also tidy and considerate. He will be doing all the work for us from now on. I could not recommend JNA high enough.

Very reliable, tidy and courteous. Work was completed on time and within budget. Justin was very honest about pricing and how we could reduce the cost as we're on a tight budget at the moment. I would recommend them.
