Our Services

Commercial and Office Building Cleaning

Your office should leave a great first impression. We keep banks, dealerships, schools, and corporate spaces clean, organized, and ready for business. Round the clock.

Medical Facility Cleaning

In healthcare, clean isn’t optional. We disinfect and sanitize medical offices, clinics, and facilities to help protect your staff, your patients, and your reputation.

Industrial and Warehouse Cleaning Services

Big spaces, tough jobs. We tackle dust, spills, and grime in warehouses and industrial sites, keeping work areas clean, safe, and fully operational.

Routine Janitorial Services

Trash removal, restrooms, floors, surfaces… We do it all, and we do it on daily, weekly, or custom schedules.

VCT Floor Care: Stripping and Waxing

Floors take a beating. We strip away old wax, deep clean your VCT flooring, and apply a fresh, glossy finish that keeps your space looking polished and professional.

Carpet Cleaning

Nothing drags down a space like stained, worn carpets. We deep clean carpets to lift dirt, remove stains, and bring back that soft, clean feel underfoot.

Power Washing and Power Scrubbing

Sometimes surfaces need a little extra muscle. We blast away dirt, grime, and buildup from sidewalks, parking lots, and walls, making your property shine from the outside in.

Post-Construction Cleaning (Residential and Commercial)

New builds and renovations leave a mess. We handle dust, debris, and leftover materials so your new space looks ready for business (or move-in day).

Building Cleaning Maintenance

A clean building isn’t a one-time job. We create regular maintenance plans that keep your property spotless, inside and out, without you lifting a finger.

Restaurant Cleaning Services

In the restaurant business, appearances matter. We clean kitchens, dining rooms, restrooms, and everything in between, making sure your space looks as good as your food tastes.

Ground-Level Window Cleaning

Streaky, dirty windows kill curb appeal. We clean ground-level windows until they sparkle. First impressions never have a second chance.

The Man Behind Blue
Diamond Janitorial

Marcio de Souza

Marcio de Souza knows what it takes to build something you can be proud of… and it starts with doing the little things right.

He’s spent over 20 years in the janitorial and commercial cleaning world, getting his hands dirty, solving real problems, and learning how a clean, well-kept space changes everything.

Before starting Blue Diamond, Marcio worked at Whole Foods, where he picked up more than just a paycheck.
He learned how to lead a team, care about the details, and treat customers the way he’d want to be treated.

Today, that same mindset runs through everything we do. From day-one training to every job we take on, it’s about pride, reliability, and doing things right. No cutting corners. Cleaning them.

Outside work, Marcio is just a guy who lives by three simple principles: Care about people. Always do your best. Work hard.

At Blue Diamond Janitorial, that’s the standard we live by because clean spaces aren't just nice to have.

They’re where great work happens.
