5 Things to Ask Before Hiring a Window Cleaning Service in Los Angeles

In a city like Los Angeles—where views are everything—clean, streak-free windows are more than a luxury. They’re a reflection of care, professionalism, and pride in your space. Whether you're managing a residential property in Pasadena or overseeing a commercial building downtown, hiring a reliable window cleaning service isn’t just about price—it’s about trust, safety, and consistent quality.

The challenge? Not all cleaning companies deliver what they promise. In LA’s competitive service landscape, anyone with a ladder and a bottle of glass cleaner can call themselves a window pro. But the right questions can help you separate fly-by-night operations from companies with real systems, insurance, and accountability.

Here are the five essential questions to ask before hiring a window cleaning service—and why Cleaning Nerds checks every box.

1. Are You Licensed, Insured, and Bonded?

Why it matters: Window cleaning may seem low-risk, but it involves ladders, tools, and access to private property. If a cleaner damages your property—or worse, injures themselves while working on-site—you could be liable if they’re not properly covered.

What to look for:

• Valid business license in California

• General liability insurance

• Workers’ compensation coverage

• Bonding (for additional protection against theft or damage)

How Cleaning Nerds measures up: We are fully licensed, bonded, and insured in Los Angeles. Our clients enjoy peace of mind knowing that every team member is protected—and so are their homes, offices, and valuables.

2. What’s Included in Your Window Cleaning Service?

Why it matters: “Window cleaning” can mean very different things. Some companies only clean the exterior glass. Others charge extra for screens, tracks, frames, or second-story windows. Without clarity, you could end up with an incomplete job or surprise add-ons.

What to ask:

• Do you clean both sides of the window (interior and exterior)?

• Are screen cleaning and track vacuuming included?

• Do you remove hard water stains or paint overspray?

• Are window sills, ledges, or skylights included?

How Cleaning Nerds measures up: We offer comprehensive window cleaning with transparent, flat-rate pricing. Our service includes:

• Inside and outside glass

• Frame and sill wipe-down

• Screen removal, brushing, and reinstallation

• Light track cleaning

• Stain and residue removal where applicable No hidden charges. No skipped corners. Just crystal-clear results.

3. What Type of Equipment and Solutions Do You Use?

Why it matters: Cheap tools and harsh chemicals can leave streaks, damage window tints, or even erode frames and seals over time. Plus, not every service is equipped for tall buildings, delicate panes, or eco-conscious homes.

What to ask:

• Do you use professional-grade tools like water-fed poles or squeegees?

• Are your cleaning products safe for tinted, coated, or antique glass?

• Do you use biodegradable or eco-friendly solutions?

• Can you handle multi-story buildings or hard-to-reach windows?

How Cleaning Nerds measures up: We use high-grade, scratch-free tools including water-fed poles with deionized water systems for streak-free outdoor results. Our eco-safe, non-toxic solutions are safe for pets, plants, kids—and the environment. Whether it's a condo balcony in Koreatown or a glass-wrapped estate in the Hollywood Hills, we’re equipped for the job.

4. Can You Provide References or Reviews from LA Clients?

Why it matters: A credible company should have a track record of satisfied customers—and they should be willing to share it. Testimonials, photos, and reviews offer real-world proof that they’re consistent, reliable, and respectful of client spaces.

What to ask:

• Do you have client reviews on Google, Yelp, or industry platforms?

• Can you provide contactable references or photos of recent work?

• Have you serviced properties similar to mine?

How Cleaning Nerds measures up: We have a growing base of loyal residential and commercial clients across LA, from Venice to Burbank. You’ll find 5-star reviews that highlight our professionalism, punctuality, and meticulous attention to detail. We’re happy to share references or examples of our work so you can see the difference yourself.

5. Do You Follow a Structured, Written Process for Every Job?

Why it matters: One of the most overlooked indicators of quality is process. Companies without checklists, protocols, or defined service standards often miss key details—or provide inconsistent results depending on who shows up.

What to ask:

• Do you have a written checklist or service protocol?

• Are your technicians trained or certified?

• What happens if I’m not satisfied with the service?

How Cleaning Nerds measures up: We don’t guess—we follow structure. Every window cleaning job is backed by a written, step-by-step process tailored to your property type. Our team is professionally trained in safety, stain identification, and glass care. And if you're not completely satisfied? We’ll make it right—guaranteed.

Why These Questions Matter More in LA

Los Angeles presents unique challenges that make choosing the right window cleaning partner even more important:

• Hard water stains from sprinkler systems, ocean spray, or smog buildup

• High-rise glass that needs specialized tools or permits

• Architectural windows with fragile materials or custom treatments

• Security concerns in gated properties or high-value homes

• Regulatory and HOA requirements in residential communities

Choosing a service without asking the right questions can lead to liability issues, subpar results, or even permanent window damage.
