What our clients say about us…

"Served as general contractor to seal and insulate my crawl space and seal the HVAC ducts as recommended by the TVA "energy right solutions " program; replace my metal roof and repair the stone chimney; conduct radon testing. Some of the work was performed by them and some was subcontracted but they scheduled, supervised and approved all the work. They were very professional and knowledgeable, using state-of-the-art techniques to increase the energy efficiency of my house. They discussed various options and the advantages/disadvantages of each as well as the cost differences. They discussed each phase with me so that there were no surprises. The subcontractors they chose were skilled in their area, respectful of my property, and diligent in completing the work. The TVA inspection following the crawlspace work was highly complimentary of the quality of the work. I am extremely happy with the energy star metal roof that was installed and pleased that the leak around the stone chimney is finally fixed. Overall, this was as painless a home improvement project as I could hope for. I got more than my money's worth"

They explained all of the steps in the process to me, in a way that was easy to understand, and they presented many options without pressuring me.
