FAQ
Frequently asked questions
Will cleaning void my panel warranty?
No. We use methods that panel manufacturers approve: pure water, soft brushes and no harsh chemicals.
Do you clean commercial solar arrays?
Yes. We clean carport, rooftop and ground-mount systems.
How much does window cleaning cost in your area?
Pricing depends on the number and size of windows, stories and whether you want inside, outside, screens and tracks. National cost guides average about $150 to $302 per visit, roughly $4 to $8 per window side, and $15 to $40 per window for high-rise and specialty access (Angi). Loyal gives a firm quote up front.
How often should windows be cleaned?
Homes typically every 3 to 6 months. Storefronts weekly to monthly. Office and multi-story buildings 2 to 4 times a year, more often near freeways, the coast or construction.
Do you clean both the inside and outside of windows?
Yes. We clean inside and out, and exterior-only service is available.
Do you clean screens, tracks and sills?
Yes. Screen cleaning, track vacuuming and sill wipe-downs can be added to any visit, and torn screens can be re-screened.
How do you clean windows on two-story, mid-rise and high-rise buildings?
We pick the access method for the building: water-fed pure-water poles and ladders for homes and low-rises, aerial lifts or roof-anchor systems for taller buildings, always following Cal/OSHA safety rules. Our team is OSHA 1910 certified and fully insured.
What is pure-water or water-fed pole window cleaning?
It's filtered, mineral-free water delivered through a long pole with a soft brush. Because there are no minerals, the glass dries spot-free without squeegee marks, even several stories up.
Do I need to be home for window cleaning?
For exterior-only cleaning, no. For interior cleaning, someone needs to let us in.
Can you remove hard water spots from my windows?
Regular cleaning won't remove mineral spots from sprinklers. Our glass restoration service will. See the glass restoration questions on this page.
Do you clean windows for apartments, condos, HOAs and offices?
Yes. We work with property managers, HOA boards and facility teams on one-time and recurring programs.
Do you do post-construction window cleaning?
Yes. We remove stickers, paint, stucco, mortar and dust from new glass using scratch-safe methods.
Are you insured and certified?
Yes. Loyal is fully insured, our crews are OSHA 1910 certified, and co-founder Luis Martinez serves on the Board of Directors of the International Window Cleaning Association (IWCA).
