I am a professional residential photographer and have worked with countless renovation and building professionals. I can honestly say that Cape Cod impressed me more than all others. From the quality of the craftsmanship and the high end materials, to the staff and the elite professionalism. I could not recommend Cape Cod more highly and strongly believe they are the best choice out there.

Cape Cod have just finished our renovation and we couldn't be happier. We've renovated a few times and they are by far the standout. Super professional, things ran on time, and any issues were handled with customer service at the forefront. The most impressive thing was how they handled the inevitable differences that arise during a big renovation. We would thoroughly recommend them.

We used Cape Cod for building an addition to our home. Every part of our experience working with them was excellent. Our supervisor informed us every step of the way and any issues were dealt with immediately and he made us feel relaxed. We are really happy with the outcome of making our home beautiful.

I have been working with Cape Cod Australia for the past two years, writing content and case studies for their website. In that time, I have spoken to many of their past customers as well as the Cape Cod team and cannot fault them in any way. Every customer is full of praise for their professionalism, expertise and can-do attitude. Their work is of a high standard and everyone I have spoken to says nothing but good things. I have even recommended Cape Cod to my neighbours who are looking for a first floor addition.
