Corey's Construction - Company History
Corey’s Construction specializes in turnkey modular homes that make building feel simple—not stressful. For 25 years, we’ve helped families of all ages, shapes, and sizes design and build homes across Pennsylvania, West Virginia, Maryland, and Virginia with clear pricing, realistic timelines, and a down-to-earth team that’s always accessible.
“Turnkey” truly means full service at Corey’s Construction. We handle every step before your home is set, including permits, site preparation, tree clearing, stormwater management, septic or sewer connections, and foundations. Every home is built in a factory-controlled environment for consistent quality, then set on a prepared foundation to minimize weather delays and reduce uncertainty throughout the build. Once the home arrives, our in-house crews take over, completing the roofing, siding, and all exterior work needed to dry in your home. Inside, we manage HVAC, electrical, and finishing work, and we also construct porches and garages to complete the design. The final phase includes lot grading, driveway preparation, and grass seeding so your property is ready for move-in.
We understand that building a home is one of the biggest investments in a person’s life. That’s why we slow down, guide each client through the entire process, and offer honest communication rather than sales pressure. Our goal is simple: combine the efficiency of modern modular construction with the personal care of a small, local business—while giving you the flexibility to design a truly custom home.
How It All Began
Corey’s Construction traces its roots back to Corey’s senior project at Bridgewater College. After earning his bachelor’s degree in Business, he returned home and began working on row-house villas in Greencastle, Pennsylvania. A year later, his father asked him to build their family’s 5,500-square-foot stone home in Hagerstown, Maryland in 2001.
That project became a hands-on education and a meaningful family milestone. Corey’s parents watched him grow into the builder he had dreamed of becoming since childhood, when he spent hours in the sandbox with his Tonka trucks. After completing that home, Corey secured his first independent customer—someone who wanted a similar home built in Greencastle—and Corey’s Construction officially began.
In the early years, Corey worked as a one-man general contractor, guiding one or two homeowners annually from design to move-in—a process that often lasted two to three years or more. Over that time, many clients became lifelong friends, sharing meals, holidays, and memories with Corey and his wife, Jessica.
Growth, Setbacks, & Determination
In 2004, Corey’s father retired from his career as a CFO and stepped in to manage the company’s bookkeeping. His support came at the perfect time: business was booming, and Corey’s daughter Halie had recently been born. As Corey led the crews in the field, John became the company’s anchor in the office, taking over as CFO, streamlining accounting practices, and ultimately becoming a partner whose leadership continues to guide the company’s long-term growth and stability.
Then came the 2008 housing crash. Like many in the construction industry, Corey’s Construction faced its toughest season yet, until a local doctor signed a contract for a new home after completing a medical procedure on Corey’s brother- what a way to sell a house! That single project kept the company afloat for another year, long enough to survive the downturn.
Corey’s brother Michael graduated in 2008 with degrees in philosophy and history and planned to move away. But after a summer helping Corey’s concrete crew, conversations about the company grew deeper. One thing led to another, and Mike never left town. Mike’s process-driven mindset complemented Corey’s builder’s vision, and he eventually became a partner—helping shape the systems, structure, and growth of the business.
Expanding Into Modular Construction
As the economy recovered, Corey welcomed his second child, a son, Cooper, in 2010. Many clients were finding it difficult to afford both land and a traditional stick-built home. Corey, who had been attending the International Builders’ Show for years in search of new ideas to support his growing company, eventually connected with Ritz-Craft, a modular home manufacturer.
Modular construction offered exactly what customers needed: high-quality, customizable homes with predictable costs and faster build times. The new partnership with Ritz-Craft allowed Corey’s Construction to expand its offerings and serve a broader range of clients—from first-time homebuyers to families building on their own land, including those adding secondary homes on family property.
Even Corey was surprised when the number of homes they were able to build annually climbed into the double digits. Modular construction helped remove the stress of constantly shifting schedules caused by weather and coordinating multiple subcontractors across four states.
Building Infrastructure For The Future
In the early 2010, John invested in a warehouse, both as a revenue stream and as the company’s first true headquarters. Before then, the partners worked from their homes: John handling accounting from his house, Corey storing materials in his basement, and everyone juggling scattered office space.
The new warehouse in Zullinger, PA changed the company’s trajectory. It provided dedicated storage, administrative offices, and eventually the site of Corey’s first model home and customer showroom. With a full selection center, clients could finally see materials, finishes, and layouts in person, making the modular process easier to visualize and understand. Mike was in the office overseeing the administrative staff who was busy helping clients make their selections and order more houses than ever before.
The Pandemic Surge
When the COVID-19 pandemic hit, Corey’s Construction experienced an unexpected surge in demand. Even as supply chains and regulations changed constantly, interest in new homes skyrocketed. The team navigated back-ordered materials, ever-shifting state rules, and record lead times—yet continued building more than 20 homes per year.
Despite shortages of even basic materials and interest rates reaching their highest levels in a decade, families continued to build, and Corey’s Construction pushed through one of the most unpredictable periods in modern homebuilding.
During the pandemic, Mike was not only helping guide the company through constant industry changes—he was also starting a family, with his first daughter born in 2019. Balancing newborn life with supply shortages and shifting regulations wasn’t easy, but his steadiness and commitment played a key role in carrying the company through a challenging season.
Today & Beyond
By 2023, the homebuilding industry had settled into a “new normal,” marked by one final round of post-pandemic price increases. Despite these challenges, Corey’s Construction continued to grow, strengthening its reputation as a trusted custom modular home builder across the quad-state region. In recognition of our resilience, dedication, and high-quality work, Corey’s Construction was proudly named Builder of the Year in 2024. The next generation continues to grow, with Mike welcoming two more children in 2022 and 2025.
At Corey’s Construction, our strength isn’t just in the homes we build—it’s in our people. With a dedicated team of 35+ skilled professionals, from project managers and craftsmen to accounting staff and a pre-construction team, every member plays a vital role in bringing our clients’ dreams to life. Many of our employees have been with us for a decade or more, and some were even clients themselves, reflecting the stability, trust, and family-like culture that sets us apart. The next generation is on the horizon as well. Corey’s two children are now young adults, and nothing meant more to him than hearing his son Cooper tell his high school counselor that he hopes to one day take over the family business. Mike’s family is growing too—now a father of three, he’s raising the next generation with the same values of hard work and dedication.
Today, we proudly serve clients within a 60-mile radius of our Zullinger, PA headquarters, building 30+ homes annually throughout Pennsylvania, Maryland, Virginia, and West Virginia. Corey’s Construction sold 60 houses in 2025 and Corey made the decision to finally hire a General Manager. This strategic decision made it possible for Mike to shift to Vice President where he will oversee the sales and pre-construction processes and staff. Corey remains actively involved in every project—taking calls, visiting job sites, and ensuring that our clients experience personalized service, clear communication, and no hidden surprises. He continues to “play in his sandbox”.
Together, we combine expertise, care, and consistency to make building a home straightforward and enjoyable. At Corey’s Construction, we build homes in a way that brings peace of mind, not stress.
