Pre-Drywall Inspections: Your home should be built to three standards; the Pennsylvania Uniform Construction Code (UCC), manufacture specifications when applicable, and current workmanship and industry standards.
Your Inspector Should be Trained and Certified in the Residential building Code
A qualified inspector who works for you can provide a trained set of eyes to check for problems, mistakes, and miscues before they get covered up and it's too late. A pre-drywall inspection by a qualified inspector can add another layer of quality control.
I recommend you ask your builder to have a pre-drywall inspection by a qualified inspector. A reputable builder should have no problems allowing you to have your own inspection, in fact, many welcome it. I have worked with many builders over the years helping them raise the quality of the homes they build.
Homes are built by humans and humans make mistakes. Homes are built by many different contractors, roofers, plumbers, electricians, HVAC installers, framers, and drywall installers. It's possible one of them could have had an off day, just make sure you don't end up paying for it later.
If you are having a new home built call to schedule a pre-drywall inspection
