Diamond Certified Expert

Only companies rated highest in quality earn the prestigious Diamond Certified designation. Alcal Home Services is proud that our customers recognize our commitment to excellence.

Diamond Certified Explains Their Rigorous Certification Process

“Our rigorous 12-step company certification process is the most reliable anywhere. We survey a large, random sample of REAL customers by telephone to get the most accurate rating and verify only actual customers are responding. By surveying from a company’s entire customer base, we ensure the results of our study, good or bad, truly represent the company’s customer satisfaction level. All responses for each Diamond Certified company are displayed on its Diamond Certified Company Report page. Diamond Certified companies are held accountable and never allowed to sit on their reputations. We conduct ongoing research and ratings. Companies must keep up their high performance. If they don’t, they are dropped from Diamond Certified.”
