What our customers say

Did a professional job in a timely manner. Also did a few extra small tasks at no additional charge. I liked that Bob talked with me about the cheapest way to get the job done and didn't suggest unnecessary work.

–L. H. Home Advisor

Bob and his team were absolutely perfect. They showed up on time, they did as they promised, they endured the thousand changes I made, and they cleaned up after themselves! They didn't lose any of my cats either. I highly recommend Bob for any project. He will definitely do my bathroom remodel next.

Stacy C. Yelp

Fantastic! Bob's crew was wonderful and did an A+ job! We couldn't have asked for a better outcome, the kitchen looks like it took 3 months instead of 3 weeks! We will be remodeling our 2 bathrooms next summer and you can bet we will be using Bob with B3 again!

Victoria F. Angie

I am a full time creative professional who notices all the small details. Bob and B3 Construction are the only company I would trust to work on my home. Their attention to detail, work ethic and honesty are the reasons we keep coming back to B3 Construction for all our new construction and remodeling needs.

J.V Houzz

Bob Harris, CEO is a hands-on leader. Jake onsite chief was completely engaged in the project. There was one issue, a cell phone call brought Jake back in short order. Problem solved. All workers on time, professional and pleasant. We recommend B3 Construction without reservation.
