Each business is scored on signals we can verify from public data: a live, secure (HTTPS) website, mobile-friendliness, a published phone number and website, and fit with the cleaning services category. We do not collect or display customer reviews, and we do not accept payment for placement. Businesses can claim their listing to correct contact details, but the rank is fixed by the data. Owners can claim a listing for a Verified badge and a direct link; sponsors appear only in labeled blocks outside the numbered list. Neither changes rank.

Each listing is scored on public signals we can check ourselves: whether the website is live and secure (HTTPS), whether it works on a phone, whether a phone number and website are published, and how closely the business matches the cleaning services category. We do not collect customer reviews, so no star ratings or review counts appear here, and no business pays for placement.
Use this list to shortlist two or three cleaning services, then read their Google reviews yourself, confirm license and insurance, and get written estimates before committing. The score here is a filter, not a verdict.
Licensing in Delaware runs through the Delaware Department of Labor, which registers contractors, and the Division of Professional Regulation, which licenses plumbers, electricians and HVAC technicians. Before hiring anyone in Wilmington, check a general contractor in the Department of Labor contractor registry (contractorregistry.delaware.gov), and a plumber, electrician or HVAC technician in the DELPROS license portal (delpros.delaware.gov). Contractors also carry a Delaware business license. Also confirm current liability insurance, and get the license number in writing on the estimate.
