FAQs
Are the cleaners insured and bonded?
Yes. Everyone who works in your home or business is fully insured and bonded for your peace of mind. Our cleaning company takes safety and professionalism seriously, so you can feel confident about who’s in your space.
What is included in a standard cleaning service versus a deep clean?
Standard cleaning covers everyday tasks like floors, surfaces, bathrooms, and kitchens. A deep clean goes further by tackling areas that don’t get attention every week, such as baseboards, appliance interiors, and detailed scrubbing. It’s helpful for seasonal cleaning or when your space needs extra care.
Do companies offer eco-friendly or green cleaning options?
Yes. We offer safer products that reduce harsh chemicals while still giving a strong clean. If you prefer eco-friendly supplies for your home or office, just let us know.
How long has the company been in business and can references be provided?
LSI3 Properties has been in business since 2009. The company was founded by Rosalind Robinson Ambrose, a service-disabled U.S. Army veteran with decades of experience in business, HR, training, labor relations, education, and supply chain. Over the years, we’ve built long-term relationships with clients across Maryland, and we’re happy to provide references so you can hear about their experience with our services.
What is the policy on pets?
Pets are welcome. Just tell us what to expect so we can clean safely and comfortably around them. If your pet needs to be secured during certain tasks, we’ll work with you on the best plan.
