Our Prefab Colonial Homes

For those seeking the charm of a classic colonial-style home but lacking the time to see it built, the Guardian Homes by Keystone team has the perfect solution. Our modular colonial homes come prefabricated, reducing the construction time by weeks or months so you can move into your brand-new space sooner. Once you have the land, building permits, and foundation, we’ll take care of building the home. Our responsibilities to you include:

Pre-delivery construction: Choose from one of our innovative floor plans, or work with us to create your own. Whatever ideas you have for your colonial-style modular home, we can fabricate them in-house.
Home delivery and erection: We’ll bring your home to your property and properly set it on your foundation with a large crane and erecting equipment.
Finishing: Our construction professionals will handle all finishing work, like roof installation, drywalling, painting, and flooring installation.
Running connections: We complete all internal heating, electrical, and plumbing connections. By the end of our work, you’ll be ready to start moving in furniture.
