Our Work in Dennis
Three reasons Dennis customers stay with Sherlock Holmes Cleaning Services
Employees, Not Subcontractors
The people in your property are on our payroll, keyed and badged. Staff cover is our problem to manage, not yours to notice.
Put Right Within 24 Hours
Point at what was missed and we come back to it. No argument, and nothing charged for the trip.
Told Straight
If a surface is worn rather than dirty we say so before quoting. Cleaning harder does not fix a floor that is already failing.

Free written estimate. We look at the actual space, tell you what it needs and give you a price that does not move later.

Sand and salt are our specialty.
A coastal house in Dennis gets dirty differently. Salt film on the glass, sand ground into the pile, damp in the corners. We clean for that, not for a suburb inland.
