We deliver a full range of building and grounds services through a network of licensed, insured Delaware operators — while Cornerstone manages the contract, quality control, and compliance end to end.
Recurring and one-time commercial cleaning for offices, community buildings, and public facilities.
Carpet cleaning, extraction, floor stripping, waxing, and burnishing — performed by certified specialists.
Mowing, trimming, edging, seasonal grounds care, and landscape maintenance for multi-site properties.
General building services and one-time turnarounds, including post-event and post-construction cleanup.
Pest and rodent control managed through licensed pest-control partners.
Bidding, contract administration, wage-determination compliance, inspections, and reporting.
Cornerstone is led by Dante Law, MS, who brings 17 years of operations leadership — supervising staff and daily operations across multiple sites, ensuring regulatory compliance and accurate reporting, and maintaining consistent quality and safety standards. We pair that management discipline with hands-on trade expertise from our vetted, certified subcontractors.
