About Heritage Building Services LLC

Reliable. Sustainable. Built on a Foundation of Trust.

Locally owned and operated in Renton, WA — proudly serving commercial facilities across King, Pierce, and Snohomish counties since our founding as Neli Cleaning Services.

Our story

Heritage Building Services began as Neli Cleaning Services, a family-run operation built on a straightforward belief: every facility deserves to be maintained with consistency, care, and pride. What started with a small roster of clients and an uncompromising commitment to quality has grown into a full-scale commercial janitorial and building maintenance company — rebranded, modernized, and built to serve the evolving needs of the Pacific Northwest business community.

When we transitioned to Heritage Building Services LLC, we brought our entire foundation with us: the work ethic, the accountability, and the personal relationships that define how we operate. Today we combine that hands-on heritage with professional systems, trained and vetted staff, and sustainable practices that reflect the values of Washington businesses and the communities we serve.

The name evolved. The commitment never did.

What we stand for

Reliability you can plan around

Consistent schedules, proactive communication, and a team that shows up — every time, without exception. Your facility operation shouldn't have to work around your cleaning vendor.

Accountability at every level

Our staff is background-checked, uniformed, and trained to ISSA-aligned standards. We are fully bonded and insured, and we document our work so you always have visibility and peace of mind.

Transparent, fair pricing

No hidden fees. No surprise charges. We provide clear proposals, honest scopes of work, and pricing that reflects the actual needs of your facility — not a one-size-fits-all rate sheet.

Community-rooted service

We are a locally owned business serving local businesses. Our clients are long-term partners — not account numbers. We invest in those relationships the same way we invest in our work.

Our mission

To deliver reliable, high-quality, and environmentally responsible building services that create cleaner, safer, and more productive workplaces for the businesses and communities of the Pacific Northwest.

Green cleaning — a Pacific Northwest standard

Eco-responsible products

Biodegradable, low-VOC cleaning agents that protect indoor air quality and minimize environmental impact.

Water conservation practices

Efficient application methods and equipment that reduce water consumption on every job.

Waste reduction protocols

Minimized single-use materials, responsible disposal, and product selection aligned with Washington sustainability standards.

Safer workplaces

Our cleaning protocols reduce chemical exposure for your employees — not just meet compliance minimums.
