Do Lowes Home Improvement stores have their own in-house installers?

No they do not. They hire outside companies to sub-contract the work that will be done at your house. These companies have gone through extensive background searches, are properly insured, and perform some of the best quality workmanship in their respective industries. Lowes hires only the best installers to work for their stores. They want to send top-notch companies into customer's homes.  more
