Heritage Building Services LLC is owned and run by Doraneli Quiroz. The company takes janitorial contracts, medical and dental suites, post-construction handovers, floor care programs, day porter placements, and the move-out and turnover work that property managers need done on a deadline.
The name is not decoration. Heritage is what you leave behind in a building — the difference between a space somebody cleaned and a space somebody cared about. Every job is meant to leave that mark, which is a harder standard than passing an inspection.
We are deliberately small. That is a constraint, and it is also the product: a small company can put the same people in your building every week, can be reached directly by the person who signed the contract, and can afford to tell a client the truth about what they do and do not need.
Everything on this website has been confirmed by the owner. We do not publish a testimonial we cannot attribute, a service we do not perform, or an address we do not operate from. If a claim is not on this page, it is because it has not been verified yet — not because we were being modest.
How we work
We say no
If a job is outside what we do well, we say so and point you elsewhere. A bad fit costs more than a lost quote.
No surprise invoices
The scope is written before the first visit. If something falls outside it, you hear about it before the work happens, not after.
Twenty-four hours to make it right
Call within a day of any visit you are not happy with and we return and redo it. There is no form and no argument.

Tell us about the space and we will come back with a written scope and a number. No obligation, and no pressure if the answer turns out to be no.
