"I chose Simple Home Energy Solutions after getting several bids for doing spray foam in the attic. His experience was clearly superior to the other contractors. Robert identified several problems right away (missing insulation, mold in attic and squirrel nests) and was able to redo the insulation in the time frame I needed. He communicated with me throughout the process and made sure any problems we found were addressed. I would definitely work with him again for future insulation work."
