Drywall Inspection Standards – New Construction
Learn About ASTM Standards for Your new home!
Inspections by Bob spends a significant amount of time walking through your new home and checking the safety and quality of items including structural, heating, cooling, roofing, and more. Some home inspectors stop there, but we don’t. When our home inspectors are walking a new home as part of a New Construction final walkthrough, we often use painters tape to mark cosmetic issues as well as we move from room to room.
Did you know that there are ASTM standards that describe the level of finish?
Drywall finish is broken into 6 levels (level 0 through level 5) and each is progressively ‘nicer.’
Level 0 is typically what we see in Garages where no painting is required.
Level 1 is basically primed and ready for the next step, but unfinished, or the finish undetermined
Level 2-3 economy painted and slightly better
Level 4 Recommended for non-critical lighting with a smooth finish. Primed with 1 coat of paint
Level 5 Recommended for critical viewing. This is the level where the best paint surface is required. The entire surface is skim coated and then primed with two coats of paint.
The specifications call out how many layers of joint compound and much more. It is important to note that the painting industry is closely tied to the drywall industry. In fact, some of the best descriptions of how the DRYWALL is supposed to be prepared is found on Painting industry websites:
Many builders follow some version of the National Association of Home Builders (NAHB) Residential Construction Performance Guidelines:
These guidelines quantifies defects and gives good descriptions of defects, how they are to be measured, and the corrective measures that the builder is supposed to apply. Their description of drywall defects is best summed up by their guideline:
Any such blemishes that are readily visible from a standing position facing the surface at distance of 6 feet under normal lighting conditions are considered excessive.
Some builders stick to this 6′ guideline rigidly, while others may have their own QA people go through with contrast lighting prior to the final walkthrough.
