Modular Home Construction
Our modular homes combine precision manufacturing with customizable design. Built in controlled environments to meet International Residential Code standards, these homes offer superior strength and energy efficiency. Sections are transported and assembled on-site, reducing construction time by up to 50% compared to traditional methods while maintaining full code compliance.
Site Preparation
We handle complete site development including excavation, grading, and foundation installation. Services cover septic system placement, utility hookups, and terrain preparation to ensure optimal home placement. Our team manages permits and coordinates with local authorities to guarantee all regulatory requirements are met before construction begins.
Custom Home Design
Clients work directly with our designers to modify existing floor plans or create entirely new layouts. We incorporate client preferences for room configurations, material selections, and exterior finishes while maintaining structural integrity. This service includes 3D visualization tools to help homeowners visualize their completed project before construction starts.
Foundation Installation
We offer multiple foundation options including full basements, crawl spaces, and slab foundations. Each includes waterproofing, proper drainage systems, and code-compliant structural support. Our foundations are engineered to match local soil conditions and climate requirements, ensuring long-term stability for modular structures.
Utility Integration
Our team installs complete utility systems including electrical hookups, plumbing connections, and HVAC systems. We coordinate with licensed contractors to ensure 200AMP electrical service, PEX plumbing, and high-efficiency heating/cooling systems meet all safety standards. This includes final inspections and testing for immediate occupancy readiness.

Report
We had two options: to buy a house or to to build a new one. Our family spent some time considering those options. After the project was finalized we understood that buying was not even an option. We are so happy to have a new home which is solidly constructed, well insulated and located exactly where we wanted and built how we wanted. If we had to decide one more time to build or to buy, we would choose the modular option again and we would work with Roy's Home Center again. We thank the management of the company and the workers for doing their best.

Excellant experience in the end, and love our new home. Contracted complete project with Roy's and was best way, due to delays in construction over the last year. In the end it was the power company delay that slowed completion even with a years notification of the project. Reggie and Bill were great to work with as were Roy's sub contractors. WELL DONE!

Although we opted to take a different path, Reggie was very understanding and helped make that possible. He has been there for years and is very knowledgeable.

The girl in ther office was pretty nice, and very informative. I really liked the two mobile homes I looked at; so much so, that I'm looking into getting financing toward the purchase of a mobile home from here.
