About Nicole

Nicole Henn is a bona-fide Baltimore girl! She’s had a thing for cleaning since she was knee-high to a blade of grass! She started Park Avenue Cleaning as a Howard County cleaning service in 2003. All she had back then was a vacuum cleaner, a bucket and mop — and a couple good friends who would help out on the weekends.

Today the business has grown to employ numerous talented, loyal team members. Nicole still trains each of them herself. The custom-cleaning system she developed over the years helps team members confidently deliver the level of service that creates happy customers!

When you work with Park Avenue Cleaning, expect “white glove” service every time!


A Howard County Cleaning Service

We are all native to Howard County and Central Maryland, and know the area well. Most of us are busy parents, juggling many roles. We are all involved in our communities, together and as individuals.

The results of your house cleaning will only be as good as the training, knowledge, and experience of the people doing the job. Our team has longevity in the industry. We all know how other companies do things, so we all recognized the difference when we got to Park Avenue Cleaning. The difference between just ok and great.

Experience Counts

The crews we send to your home have been thoroughly vetted and rigorously trained. We’re a Howard County cleaning service and we know the area well. We are proud to say that our crews have an average tenure of 10+ years in the industry.

What this means for our clients is consistent quality that you can depend on, and a reliable customer experience. We’ll send the same lead technician every time, so they get to know your home — and your preferences.

At Park Avenue Cleaning, we know the science behind cleaning – and this knowledge shows up in the many details you’ll notice, as well as the ones you won’t:

  • the chemical composition of common household cleaners
  • choosing effective cleaners with low impact on indoor air quality
  • what “green cleaning” really means
  • how to avoid cross-contamination
  • the know-how to clean for allergy-sufferers
  • pet- and small child-safe cleaning
  • natural, non-commercial cleaning

For us, staff longevity means we are not constantly training new people. We don’t have to hire on the fly. For you, it means you don’t get rookies.

There’s nothing like a house that’s cleaned by professionals.
A very affordable luxury.

How We Work

The wonderful thing about recurring residential cleaning service is that we tackle all the areas that you seldom get to. We like to say that “our Standard Maid Service” is the other guys’ “Deep Clean.”  Because, if you have our recurring maid service, deep cleaning is embedded in the service. Here’s a copy of our Maid Service Checklist. And here’s our Rotation Schedule for deep cleaning.
