Our Village suggested that our extremely high water bills may be due to leaky toilets. So we contacted Black Diamond to check our plumbing, and they sent Luis over. Luis discovered that 3 of 4 toilets did indeed leak, and he fixed them all in the same afternoon. Personable and professional, Luis took us through the process and explained as to why there were leaks, all the while expertly fixing the leakages. Black Diamond is fortunate to have an employee as dedicated as Luis. They should view him as an asset to their company.
