Our Window Cleaning Process
Every job starts with a full inspection and ends with a walkthrough you approve.
1
Full Property Inspection & Assessment
Before we touch a single pane, we walk the entire property with you to evaluate window locations and layout. We identify every window type, from double-hung and casement to fixed panes, then note any problem areas including hard water stains, paint transfer, or screen damage. We also check for safety concerns, fragile glass, and access requirements for both interior and exterior work.
2
Protection Setup & Job Preparation
We protect your home or business from the start, laying down drop cloths and running through a detailed prep checklist before any cleaning begins. Screens are carefully removed and inspected for damage, tools and cleaning solutions are staged, and we confirm any special requests or instructions so nothing gets missed.
3
Thorough Interior & Exterior Window Cleaning
Every window is hand washed or cleaned using pure water-fed poles, depending on the job. We work through stubborn dirt, mineral buildup, and surface residue, then wipe down all frames, sills, and tracks with the same attention to detail. Glass is finished with microfiber cloths and squeegees, leaving a streak-free result inside and out.
4
Final Review, Touch-Ups & Walkthrough
Once every window is done, we run a full inspection across the entire job before packing up. Screens are reinstalled securely, window function is confirmed, and any spots that need a second pass are handled on the spot. We then walk through the results with you to confirm 100% satisfaction before we leave.

About STL Window Cleaners
STL Window Cleaners was started by Andy Lombardozzi, who has worked in the window and door industry since 2005, on the installation and replacement side. He also leads STL Windows and Doors, which has served Greater St. Louis since 2014.
It started because his window and door customers kept asking the same question: who can we trust to clean these? He wanted somewhere to send them that he could stand behind, so he started one.
We know how glass, frames, seals, screens and hardware go together and how they fail. If a pane is cloudy because the seal has gone rather than because it is dirty, you will hear it from us.
4 Window Cleaning Myths, Set Straight
Most homeowners have at least one of these beliefs. Here is the truth behind each one.
Myth
“I can clean my windows just as well with paper towels and glass cleaner.”
Household products leave behind streaks, lint, and cloudy residue that attracts more dirt over time. Professional cleaning uses purified water and proper tools to remove mineral buildup, oxidation, and grime that store-bought products cannot touch. The difference is visible immediately.
Myth
“It’s not worth hiring a pro just for exterior windows.”
Exterior glass takes the most abuse from weather, pollen, hard water, and oxidation. Reaching second-story windows safely requires the right equipment and training. It is one of the most common jobs homeowners underestimate until they are on a ladder realizing the results still look streaky.
Myth
“Rain will undo the cleaning anyway.”
Rain on clean glass leaves far less residue than rain on dirty glass. And if spots do appear within 48 hours of your service, we come back and touch up the affected glass at no charge. That is exactly what our 48-Hour Rain Clean Guarantee covers.
Myth
“Window cleaning is only for the spring.”
Spring and fall are the most popular times, but clean windows make a real difference year-round. Winter light is limited, so clarity matters more when there is less of it. Summer pollen and heat buildup dull glass faster than most people realize, and regular cleaning prevents that buildup from causing lasting damage.
