Just a note to express my gratitude in the job completed recently. Both of my boys had battled respiratory/allergy issues prior to completion of the sealed crawl space. Due to the excessive rain and heat in early spring, we experienced the unpleasant effects of saturated soil under the house. Since the job was completed, both boys’ health has improved and there are no signs of any prior problems. Here’s to hoping our electric bill falls this summer as well! Thanks for the good work.
