Featured Testimonials

Five black stars.

SZ Classic Homes of NJ recently completed construction of an addition to my home, as well as the demolition of the existing garage and building of a new garage. It involved a lot of work and moving pieces to make the existing house look and run seamlessly with the new addition and new garage, but SZ did a wonderful job! The owner of SZ, Sebastian, was so responsive and patient to my multitude of questions, as were his employees. They did fantastic work and I would use them again on any future projects!

We had a wonderful experience working with Sebastian for our renovation. He took the time to really understand what we were looking for. What we truly appreciated was that he didn’t just say “yes” to everything. When he felt something might not be the best idea, he kindly explained why and offered alternatives that made more sense. Looking back now, we’re so glad we took his advice—those decisions have really paid off, and we’re grateful for his experience and honesty.
