Customers reviews

Cullen with Centennial is the ultimate pro. I'm an architect, and it is apparent to me that he understands construction, and more importantly he operates with the highest level of integrity and is extremely thorough. These are the qualities you want in an inspector. He works for his client's best interests - not the real estate agent's

I've been greatly impressed with the work of Centennial Inspection for several years and multiple transactions. I've dealt with other inspection companies that left me feeling like I wasted my time. Cullen and Mac are professional, courteous, knowledgeable, and exceptionally thorough. Additionally, they are very responsive in scheduling and communication. All this, and fair pricing. Highly recommend them!

I highly recommend Centennial Home Inspection Services and have hired them 3 times for different purchases. Bruce and Cullen are both excellent to work with. They are very thorough and will take the time to talk through issues you may not be familiar with.
