Most disappointment with cleaning services traces back to a conversation that didn't happen up front. These are the questions that prevent the common problems.
Who actually shows up?
The single most important question. Some services rotate crews each visit. Others assign one or two consistent cleaners. Consistency matters more than people expect — a cleaner who knows your home gets dramatically better over time.
Do you bring supplies, or do I?
Both models exist. Supplies-included services typically charge more but mean less to coordinate. If you have allergies or pets, ask what products they use.
What's your detailed task list?
For both deep cleans and recurring service. Get it in writing if possible. A service that can't or won't share a task list is one to be careful with.
Are you insured and bonded?
Insurance covers damage; bonding covers theft. Both should be standard. Ask for proof if you have high-value items or will be out during cleanings.
Scheduling and cancellation policy
How far in advance to cancel, what happens if they cancel, holiday and vacation handling, rescheduling rules.
How do you handle valuables and pets?
Reasonable services have a clear protocol. Ask about reactive pets specifically.
How do you handle complaints?
The question itself is the test. A clear answer means established process.
The trial-visit option
Some services let you book a single visit without committing. If you're unsure, that's the safest evaluation.
