Benefits of Building a Modular Home With Homes by Keystone

Founded in 1966 in Franklin County, Pennsylvania, we’ve built nearly 10,000 homes for residents throughout the Mid-Atlantic region. When you partner with us, you gain these significant benefits:

Speed: Our simultaneous site preparation and factory construction cuts your build time by 30% to 50%. While your foundation takes shape, your home modules are being built in our climate-controlled facility in Waynesboro. Most homeowners move in within four to nine months from order to completion.
Quality: Factory construction means precision engineering, rigorous quality control, and protection against weather damage during construction. Our homes are built to withstand Pennsylvania’s weather, from heavy Cumberland Valley snow to summer storm systems.
Protection: Every home includes our factory warranty on workmanship and structure, plus extended coverage through our membership with Residential Warranty Company.
Cost certainty: You’ll receive transparent pricing up front without the surprise overruns common with site-built projects.
Free delivery: We deliver for free within 50 miles of our factory, representing a massive cost-saving advantage for homeowners throughout our service area.
