Testimonials

Hear it from the heart: Read what our tenants have to say in their own words.

If I could give them 10 stars I would. I have had the pleasure of working with CWB on more than one occasion- first in 2009 to do a complete re-model of my 10,000sf building. The best part of this experience was the trust Steve and his team earned. I was inexperienced and they guided me every step of the way, always having my best interest in mind. In 2020 I expanded to 35,000 sf and I never had a doubt of who I would want to help me build my dream. The construction was a two year project- done over the entirety of Covid and I am proud and honored to say that I took great joy in always answering the same whenever some would ask – how’s your building coming/ how is your contractor. WIth Pride I would always answer, running right on time, – I am so lucky I have the best contractor. Steve and his guys worked tirelessly around our open business one section at a time keeping us up and running, never causing me or my team to miss a day of work– even during a pandemic. Using CWB was one of the best business decisions I have ever made, and if I was to build another building I would use them again.

CWB has designed and built three buildings for us over the past 15 years, and with each project their team has been exceptional to work with. They recently completed a beautiful new 1800 sq ft office and a 7200 sq ft garage and we couldn’t be more satisfied. CWB’s high level of workmanship and professionalism are unmatched. When they say they’re going to be on site, they are on site!! I highly recommend using CWB for your next development. You won’t be disappointed!

CWB, and Larry especially, was amazing to work with for the entire process of building our new state of the art facility. Larry helped us every step of the way from day 1 with sketching out an idea of what we wanted, to attending the town meetings with us for permits, to fielding the everyday texts and phone calls from us with questions and ideas. Everything went great for us, and we just hit two years in our new building and everything is still just as great! We HIGHLY recommend CWB!
