Moving in or out and need a deep clean. Or you want regular cleanings but keep hiring people who do a surface wipe and call it a day. The DMV cleaning market is huge, which means there are great independents and absolute disasters - and sometimes it's hard to tell before they show up.
A good cleaning crew has a checklist and sticks to it. They know to clean inside microwaves and behind toilets without being asked, to dust ceiling fans, to actually scrub grout lines. If you want specific things done differently - certain products, certain rooms prioritized - they listen and remember. Communication is half of it.
Deep cleans run $200-$400 for most homes. Regular biweekly cleaning runs $100-$200 per visit. Ask if they're bonded and insured (protects you if something breaks or goes missing), and whether the same cleaners come each time. High turnover at a cleaning company is a red flag - it usually means the owner isn't paying well, which shows up in the work.
