  • Testimonials

  • Look no further. It is extremely rare to feel absolutely wonderful with respect to service these days! Glenn of Certified Plumbing came to our house because our toilet was having issues, which was causing temperate problems in our shower. Glenn had my trust right when I met him at my front door. He was very kind and neighborly. With patience and diligence, Glenn fixed the issue within a couple of hours (including the time to run to the store to grab a part). My toilet and shower now work better than they ever have. Fran at the office stayed in contact with me through the whole process and followed up with me after to make sure everything was working properly. Certified Plumbing is an example of how service is supposed to be: memorable! Certified Plumbing is the only call I will make for plumbing. Leonard – Littleton, CO
