At SanMar Building Services, we deliver top-tier office cleaning across New York City, adapting to every size and layout. We handle everything from open spaces and team-cluster arrangements to cubicles and executive suites.

Here’s how we can help:

  • Consistent, high-quality B2B office cleaning at your budget level and the needed frequency — daily, weekly, or monthly.

  • A seamless extension of your organization that works quietly behind the scenes to maintain a spotless, welcoming environment.

Our experienced, well-trained crews use the most up-to-date equipment and products.

    Frequently Asked Questions

    A.1. A hybrid cleaning plan scales based on your actual foot traffic. If your team is only in the office three days a week, you should not be paying for five days of full service. We adjust our schedule to clean immediately after your busiest days. On the days your office is mostly empty, we scale back to basic upkeep or skip the day entirely. This keeps your space looking great without wasting your budget on days when no one is there.

    A.2. Absolutely. Our staff is fully vetted, and SanMar is a licensed, bonded, and insured B2B cleaning company. We strictly adhere to the access and security protocols of high-security NYC office buildings like banks, law firms, and tech spaces.

    A.3. No. We bring everything needed to do the job right, from commercial vacuums with HEPA filters to safe, green cleaning products.

    A.4. We have strict keyholding and alarm protocols in place. Your dedicated cleaning crew is trained on your specific building security system to ensure your office is locked and alarm activated properly every time they leave.

    A.5. No. We build service agreements based on what your office actually needs, rather than trapping you in a rigid corporate contract. We keep our clients by doing good work, not by relying on fine print.

    A.6. We calculate pricing based on how many hours the job will take, rather than just looking at square footage. For example, a large open showroom takes much less time to clean than a smaller room packed with six to eight desks. Because every layout is unique, a manager does a brief on-site walkthrough to provide a highly accurate quote. To give you an idea of concrete numbers, average commercial janitorial rates in the NYC market typically range from $30 to $75 per hour, depending on the specific needs and layout of the office.

    A.7. We have a satisfaction guarantee and formal complaint procedures in place to make it right immediately. If something is ever missed, we want to know about it so we can fix it and ensure consistent, excellent results moving forward.
