Keystone Maintenance LLC

Keystone Maintenance LLC operates as a multi-trade contractor serving Myrtle Beach and surrounding communities along the South Carolina coast. With a perfect 5.0-star rating across 26 customer reviews, the company has established itself as a trusted provider of comprehensive home maintenance services. The business maintains service coverage across at least seven communities, including Conway, Murrells Inlet, North Myrtle Beach, Socastee, Loris, and Surfside Beach. Homeowners in these areas can access same-day and 24-hour emergency service for urgent issues, and the company offers dedicated discount programs for seniors, veterans, and first responders as a gesture of community appreciation.

What distinguishes Keystone Maintenance from competitors is their commitment to rapid response and transparent pricing in a market where both can be difficult to find. The company promotes 24-hour availability specifically for urgent situations, and multiple reviewers explicitly note their pricing as reasonable or notably lower than competing bids. They maintain in-house capabilities across multiple service categories including HVAC system work, exterior cleaning, and full property cleanouts, allowing them to handle projects that might otherwise require coordinating multiple contractors. Their service model eliminates the need for homeowners to juggle separate vendors for different maintenance needs.

Customer feedback consistently highlights the expertise and communication style of their lead technician Ernie, who has handled both residential and commercial projects including multi-unit HVAC maintenance at commercial properties. One reviewer described how Ernie identified a wiring error from a previous contractor that would have resulted in an unnecessary system replacement, saving the customer significant expense. Another noted Ernie took time to explain system operation and maintenance requirements after completing preventive service. These accounts reflect a technical approach where the technician provides educational context alongside the repair work, helping property owners understand their systems.
