Jack Werner believes strongly that you should never quit learning. Besides informing buyers through inspections on the particular concerns of their homes, he wants you to know more and has provided the information below.


Every A TO Z INSPECTOR has passed the national test (approximately half of all Oklahoma Inspectors have not passed any national test). We teach home inspectors at the college level.

Home Maintenance

Most us take our vehicles in for service, get health check ups, and exercise. When it comes to our home, we mow the yard and water the flowers, but do not service and maintain the house until it is needed.

You should spend approximately 1.5% of your home's value every year on repairs and maintenance. We should not wait until the roof leaks or the unpainted siding deteriorates.

But most people do wait, and that's why you need a home inspection before buying a property. That is also a good reason to get a seller's inspection so you can see what to repair before the buyers look at your home.
