How to Choose a Window Cleaner: A 5-Point Checklist
Your windows are one of the most important features of your home. But keeping them perfectly clean can be difficult and even dangerous. For homeowners asking how to choose a window cleaner in Mesa, AZ, this guide provides a clear checklist to help you find a service you can trust.
People seek professional window cleaning for many reasons. Perhaps you have family coming over and need the house spotless, or you’re selling your home and want to maximize its appeal. Most often, it’s because homeowners know how difficult and risky it can be. We once helped a client whose husband ended up in the ER after falling from a small step ladder onto a tile floor—a job we’ve proudly and safely handled for them ever since.
Beyond the immediate shine, a professional service is an investment in your home’s health and value:
-
- Protect Your Windows & Screens: Annual cleaning prevents dirt buildup from damaging the window seals. We also treat your screens with ScreenMagic, a product that applies a UV protective coating to make them last significantly longer under the harsh Arizona sun.
-
- Arizona’s #1 Window Problem: Professional Hard Water Stain Removal: Those chalky white spots are calcium and iron deposits from Arizona’s hard tap water, often from sprinklers or misters. A DIY vinegar approach is often ineffective and smelly. We perform a professional restoration using specialized powders and polishes to safely remove stains, and we can even seal shower glass to prevent future buildup. Hard water from sprinklers is a common issue for homeowners across the Valley, whether you’re in Mesa, Gilbert, Chandler, or Scottsdale.
-
- Prevent Costly Replacements: For windows in direct sun, we can build and install custom sun screens. These screens dramatically cool your home and add years of life to your windows, preventing the seals from blowing and creating that “foggy” look that can only be fixed by a costly full replacement.
The 5-Point Pro Checklist: What to Ask Before You Hire
The biggest mistake a homeowner can make is hiring a cheap, unaccountable cleaner. Use this checklist to learn how to choose a window cleaner and ensure you’re hiring a true professional.
1. Are they fully and properly insured? Many companies use subcontractors who may have let their insurance lapse. There is no state or federal mandate that forces companies to constantly verify their subcontractors’ insurance, creating a huge risk for you.
-
- What to look for: A company that has $1M General Liability insurance, Workman’s Compensation for their employees (not subs), and Commercial Auto Insurance for their vehicles. Commercial auto insurance is crucial because if a contractor has an accident on your property in a personally insured vehicle, you could be held liable.
-
- Our Commitment: We employ our technicians directly and provide a copy of our insurance certificates in every single proposal. Additionally, every Ace Window Cleaning technician is required to undergo safety training every two weeks covering topics from heat illness awareness, ladder safety and emergency preparedness. We use the IWCA’s (International Window Cleaning Association) vast resources for safety training.
2. Can you trust their technicians? You are letting workers into your home and around your family.
-
- What to look for: A company that performs professional, third-party background checks on every employee.
-
- Our Commitment: We are the only company in our area that conducts annual, national background checks on every employee, including the owner. Each team member wears a professional photo ID badge with a QR code you can scan to verify their credentials. We use Ask The Seal to perform our background and insurance verification checks.
3. Do they guarantee their work? What happens if it rains the day after your service?
-
- What to look for: A clear, written guarantee for their work.
-
- Our Commitment: We offer a 5-Day Rain Guarantee and will happily return to touch up any affected windows. For our maintenance program clients, this guarantee is extended to two weeks.
4. Are they equipped for a professional job? The right tools not only provide better results but are also safer. Windex and paper towels leave behind a chemical residue, and using a squeegee correctly takes years of practice.
-
- What to look for: A company with professional-grade equipment like pure water filtration systems and carbon fiber poles for high windows.
-
- Our Commitment: We have over $35,000 in specialized tools, including custom-built pure water filtration systems on each truck, commercial grade pressure washers, and even a mobile trailer for building new sun screens perfectly on-site.
5. Are they an established, accountable company? Every year, we get calls from homeowners whose previous “cheap guy” has simply disappeared and won’t answer his phone.
-
- What to look for: A company with a long track record, professional team, and a focus on customer service.
-
- Our Commitment: With experience dating back to 2004, we have built a culture that values hard-working professionals who are well-compensated for their efforts. You’re not hiring a random person; you’re hiring a dedicated team.
What to Expect on Service Day
