What They're Saying:


"Prior to NHQ, our first-time inspection pass rate was between 60-63%, consistently. After NHQ, our first-time pass rate with code inspectors is 97%, consistently. Even with the slight downturn in the market, our numbers are solid. Profitability has increased almost 10% in the last year and we've never achieved that kind of increase in all the years we've been in business. The evidence is hard to deny."

Josh Bollinger, President,
Bollinger Construction

"Our QA system has helped us grow as a company… and set all-time records in production. Before we implemented a QA system, we were framing 30-35 houses a month. Now we are framing over 90 houses a month. This would not have been possible without the NHQ Certified Trade Contractor program."

David Hughes,
Director of Operations,
Tilotta Enterprises, Inc.
