We had a loft conversion, side unfil (side return) & a 3 meter extension out of the back of our house. We have used JNJ builders once before and had a very positive experience with them, so didn't hesitate to use them again on our building work. Once again we had a very good overall experience with them. The quality of work and finish was very good & they came in on budget. I am always able to call on them if there are any teething problems and they do their best to come straight away to fix any problems, that are inevitable in all building projects. We would definitely use them again in the future.

Jamie and his team built and landscaped my patio garden including raised brick flowerbeds, new paving, fencing and drainage. The work was completed to a very high standard in time and within budget.

Loft conversion Jamie together with his team of workers are a pleasure to have working in your home. I found all of them courteous and willing to do a good job. He created a good working atmosphere and worked alongside them as well as directing the work. They care about providing high quality standards and finish and I felt confident that the work at all stages would be done as required. We had regular meetings to update on progress and he was willing to change my ideas on the internal plans (such as fittings and fixtures). They would clean up before leaving and he ensured they protected the house by closing off areas that would prevent debris and dust falling in as far as is possible with this type of work. My neighbour's frequently commented on their excellent way of working as well as keeping the street and area clean around and in front of the properties, I did not receive any complaint! I am absolutely delighted by the finish of the loft. If you are looking for an enthusiastic, trustworthy and committed builder then I can recommend JNJ Building Company without hesitation.
