If not labeled, the inspector's experience helps her or him estimate when a manufacturer sold specific types of units. An inexperienced homebuyer generally would not have this type of information. Obtaining the services of a qualified home inspector is better than doing it yourself. A qualified home inspector is familiar with home construction, the proper installation of construction materials and their maintenance. A qualified home inspector has also performed hundreds of home inspections.
Inspectors know what to look for and have seen a range of situations.
They investigate areas of the house and its components that the average homebuyer would not think about. Education, training, and experience are important. Ask the inspector if they belong to a home inspection organization. Qualified home inspectors must past tests and meet minimum qualifications to be accepted for membership. Home inspections are a good value.
