We originally called Dr. Energy Saver after seeing their crawlspace solutions on their website. We wanted to have something done about our dirty and damp crawlspace because our wood floors were freezing in the winter. When we saw the Clean Space Liner and how it looked in other crawlspaces we knew that it would help our problem. What we did not expect is how much it actually made a difference! Our floors have been comfortable year round and has saved us more than Dave told us it would in energy!
