Capital Service Group was founded in Charleston, SC in 1997 with a simple belief: when you champion your people and perfect your process, extraordinary results follow. Today, we're the Lowcountry's #1-rated commercial cleaning and facility services company.
From a single-client startup to the region's most-trusted facility services partner, our story is one of consistent quality and community commitment.
Capital Service Group was established with a commitment to deliver commercial cleaning services that exceed expectations.
Grew to serve North Charleston, Mount Pleasant, Summerville, and surrounding communities with a diverse portfolio of facility clients.
Launched window washing, pressure washing, floor care, day porter, and consumables management programs to become a true one-stop facility partner.
