Josh and his team have worked on several projects at our house, not least a new flat roof and large lantern. The boys were very friendly and polite - and importantly neat and tidy! Costings were very reasonable and work was carried out on time. It was also great that Josh was always available for a chat - unlike some contractors we have used in the past.

Absolutely thrilled with the work completed by Primary Construction on our 2-storey extension! From start to finish, the team was professional, reliable, and highly skilled. They built a beautiful space for us, complete with stunning bifold doors and a modern kitchen that perfectly blends with our home's style. The attention to detail was outstanding, and the quality of craftsmanship exceeded our expectations. They also kept the site tidy and adhered to timelines, which made the entire process smooth and stress-free. Highly recommend Primary Construction for any building project!

Right from the outset Josh was warm, friendly and reassuring. His project planning was timely and professional. The build quality and detail of his work of the interior improvements were first class from beginning to the end. His team were always friendly and polite and very clean and tidy. My experience was very positive and the cost was in line with the budget. Highly recommended

I recently had an extension built by Primary Construction, and I couldn't be happier with the results. From start to finish, their team was professional, efficient, and highly skilled. They worked with precision, ensuring every detail was completed to the highest standard.

The quality of the workmanship is outstanding, and the extension blends seamlessly with the existing structure. The team was always punctual, kept the site clean, and communicated clearly throughout the process, keeping me informed at every stage.

Not only did they complete the project on time, but they also stayed within budget with no hidden surprises. Their attention to detail and commitment to excellence truly set them apart. I highly recommend Primary Construction to anyone looking for top-quality building work – they exceeded all my expectations!

Thank you for an amazing job!

I called Josh at Primary Construction to do some work at my house. After a thorough consultation with him and the team, the work was quoted and carried out on time and within the budget we agreed. I’d have no hesitation recommending Josh and his team for any building work. A pleasure from start to finish
