Attic Insulation Contractors in Clemson, SC

"Hired a previous company to work on our attic and knee wall spaces. Paid through the nose. Nothing was done right. Some of it wasn't even done at all. Worst experience we've ever had with any contractor. Called Joe at EnergySmith. He sent Ricky, Steve, and Dillon. COMPLETE opposite experience. Above and beyond all expectations. Fixed the previous company's mistakes, did more than the previous company for far less than what they would have charged for this much work, and they did it to perfection (they let you check their work after every step; keep in mind, I'm an obsessive compulsive-type with excessively high standards): Thorough loose fill extraction (including sticking the hose in the soffits and scooping it in by hand, because yeah, all the soffits were FILLED with insulation), replacing all the bat insulation (was worried about this, especially in the misshapen spots and around the penetrations; nope, flawless), covering the knee walls with copper barrier (was worried about this in terms of sagging, and again, penetrations; nope, perfect), baffles between EVERY rafter, blockers to prevent loose-fill infiltration in the soffits and underneath the floors (I was afraid to ask for this because I thought it'd sound too neurotic; they just automatically knew to do it because they're magicians), air sealing (at this point, I didn't even bother to check, because these guys are amazing), loose-fill installation (yeah, what do you think? perfectly flat, no peaks or valleys, proper depth, happiness overload, what's for lunch?). Timely, professional, communicative, top tier work ethic, and really just a joy to be around. These guys are the gold standard by which I'm going to compare all other contractors."
