Debris found under crude crawlspace in Wilmington, DE
This is what Lawson Home Service's Energy Auditor found when he looked inside the crawlspace. A lot of debris was left behind which the crew had to remove. Also we can see the attempt to insulate the floor joists with the blue rigid foam board which was installed to hold fiberglass batt insulation in place above. This method usually fails because the rigid foam board does keep the fiberglass batts pushed against the bottom of the floor deck above. Cold air gets into the resulting air pockets rendering the insulation virtually useless.
