"The men were on time, knew what was needed and cleaned up after. They were a great team. I spoke with the manager who helped me decide what would be best for my situation. I recommend them to everyone for insulation of their attics. Thank you Mr. Brock. It was a pleasure."

"This was a two part job. The first part was to spray the AC ducts under a mobile home. The second part was regular type insulation under the mobile home. We are very satisfied with both parts and can already see a difference in electric bill. We would recommend calling LHS Insulation for all your insulating needs. Jane and Henry C. From Gonzales, La"
