The most trusted Commercial & Residential Inspections in the Oklahoma

Call 405-412-7861

Started in 2002 by Dr. Jack Werner (Lic. #255), A TO Z INSPECTIONS is known as one of the most thorough commercial and home inspection companies in the state! With degrees in Construction and Finance, Jack developed a process to produce the most thorough inspection a buyer could receive.

  A to Z Inspections deliver comprehensive inspections, with only state certified inspectors that are highly trained and continually updated in what is going on with construction and housing issues.

  Several inspectors specialize in water wells, conventional and aerobic septic systems, swimming pools, sprinkler systems, spas, and commercial electrical systems.

  Now Jack and his son Cord teach home inspection at the college level and provide inspections for Community Action.

It started with education, experience and an idea.

How could he provide the most thorough inspection possible?

After completing numerous inspections, Jack realized how valuable the information was to a prospective buyer. After all, the  the buyer knew that an inspector's report was giving detailed information important in their decision making. The question was in a limited time, how could he improve an inspection?

Answer: 2 inspectors instead of 1

The realtors Jack knew liked the idea of getting as much information as possible in the limited time of an inspection for their buyers. Having two inspectors meant less money for the inspectors but in the interest of the buyer, Jack proceeded with his idea.

Today, A to Z is known for their thorough inspections

If you want a through inspection of your commercial property or potential home or current home, you want an A to Z inspection. Our experienced teams will have completed a minimum of over 300 inspections and are required to have extra training and education—more than the average inspector. Even if it's last minute, Jack has always found a way to get an inspection completed.

Continuing to improve the inspection process

The old A to Z report used a lot of paper with multiple copies and sometimes the handwriting was difficult to read. Jack investigated existing software programs but found them not to be as thorough. So he hired Hettinger Design Group and together with  the inspection team, developed a digital version that was reader friendly and easy to store.

Pool and Spa Inspections

Many homes today have in-ground and above ground pools as well as jetted hot tubs. A to Z Inspections realized a need to add that to the inspection. Swimming pool inspections can be performed in conjunction with full inspections.

Septic Tank and Water Well inspections

Even though a number of homes are connected to public water and sewers, many home buyers want to live a little more out in the country. When A to Z Inspections is conducting a commercial or home inspection that has a water well and/or septic tank system, you can be assured that Jack had his inspectors trained in inspecting these important parts of a plumbing system, and can be performed in conjunction with full inspections.

We care about more than home inspections.
