Sherlock Holmes Cleaning Services · Window Cleaning · Sandwich
Sherlock Holmes Cleaning Services treats window cleaning as a measurable job, not a vibe. What comes out, how long it takes to dry and what you should expect afterwards are all part of the estimate.
The same crew comes back each visit, which is why the second clean is faster than the first and the tenth is faster than the second.
