Not if you use us! We are recessed lighting specialist (really, we are). Most of the time, we install recessed lights without any damage to the existing ceiling. In some cases, we are forced to cut a small hole to assist with the wiring, but never without your permission. We never remove large sections of drywall or cut multiple holes or channels. If someone told you they would need to ruin your ceiling, they did not know how to install recessed lights.
