"So, what's a buyer to do?

We recommend that buyers of new construction homes have periodic inspections during construction by their own inspector. And we don't just say that to drum up business for inspectors. It is a sad fact of life that many issues slip by the superintendent and municipality inspectors. You have more leverage to get action from the builder PRIOR to closing than during the warranty period. Many issues are discoverable by a good inspector prior to being covered up with drywall, but if not discovered they may not manifest into actual problems until after the warranty has expired.

In short, you need your own inspector to discover the issues at each stage of construction and have them corrected. With an expert on your side and a fact-based inspection report in hand your leverage with the builder to correct each issue is significantly improved. By doing this you also directly affect the overall quality of your finished home by maintaining good quality control during each construction stage. Quality construction doesn't just happen, it is either built in during each construction stage or it isn't. Doesn't it make sense to ensure the quality of your home from start to finish?

We recommend three separate inspections during the construction of your home:

At the conclusion of stage 1, the foundation stage
At the conclusion of stage 2, the framing, rough plumbing, mechanical & electrical stage
A final and complete home inspection at the conclusion of stages 3 & 4, the insulation, drywall, paint, trim, & finish stages
The final inspection by your personal home inspector should occur prior to your pre-closing "walk-thru" so the home will be complete (or as near as possible) and you will have the information you need for the final walk-through. If timed correctly, many, if not all of the issues discovered during the final home inspection can be corrected prior to closing and verified either prior to or during the pre-closing "walk-thru".
