What Homeowners Say About Eight Inch Nails

When we finally decided to pull the trigger on a major master bath renovation we knew where to turn. Josh and his team did a wonderful job. His designer did a great job helping us with layout and finishes and everything turned out just the way we envisioned. He's a great communicator, always responding to messages. Our project turned out great!

Master Bath Renovation
8 Inch Nails created my dream kitchen. What was an outdated, broken and non-functional space is now a modern, updated, and functional place I love cooking in. They also transformed a basement storage space into a beautiful bathroom. Their exceptional craftsmanship will stay in my 1930s house forever!

Josh is FANTASTIC! Very capable and of highest quality construction. We have used Josh and his company over many years, from bath remodels to custom window installation. He is our go-to company for any remodeling job. Can't say enough good things!
