My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

Dennis built our beautiful home in 2019. Fast, efficient and detailed. He is an amazing craftsman, cares about his work and his clients and his team is awesome. He is the only person I would trust to do work in my home.
