Justin Mercer

CORE was founded by Justin Mercer and Joe Day. They were inspired to build a better Kansas City by working together to bring a new contract services company that is able to cater to both businesses and homeowners alike. Their mission is to provide stronger builds for their customers to rely on, because they know that at the core of every structure is a strong foundation.

Together, they have over thirty years of experience working in the contractor services industry and have the extensive knowledge to take on commercial and residential jobs. Through their expertise, CORE’s team of reliable industry technicians provide services to improve the exterior and interior of any new or existing building in the Kansas City Metro area, as well as surrounding counties in Missouri and Kansas.

We ensure that our customers feel like they are taken care of, whether that is on or off the job site. Our attention to detail, along with our service guarantees and warranty, provides our customers with a sense of inclusion when they work with CORE.

CORE’s industry knowledge is all encompassing. We specialize in roofing, flooring, siding, gutters, windows, interior and exterior painting, and tile. We understand contracting projects go beyond the aesthetics of your home or business, and that’s why CORE ensures a quality job from start to finish.
