    Glass is only as good as its current condition. Even the nicest windows will look shabby with dirt, debris, streaks or droppings sitting on surfaces. Try as you might, it can feel impossible to keep up with all the stains left behind on a day-to-day basis and that is why there are Gorillas.

    More than regular janitorial services, caring for windows means handling delicate materials, all while managing heights and a variety of tools. Without the right experience, this seemingly simple chore can quickly become dangerous. Professional St. Catharines window cleaning services tackle every sort of stain, keeping your glass in great shape throughout the year.

    Exterior Windows: More than Meets the Eye

    No matter where you go, windows are your ticket to the outside world. You might be looking out onto a mountain view, staring out at the beach or just checking in on your backyard, but glass does more than just that. When clean, shining surfaces can help to control natural lighting around your space while good condition can help to regulate heat.

    Because windows are built for the outdoors, they often go unchecked for long periods. While this glass might be built tough, it is still a vulnerable material. Ultimately, glass is porous, which means sitting dirt can seep down into pores, weakening from the inside-out. A shift in temperature or a slight bump can mean costly breakage, but routine washing services can help.

    Avoiding DIY

    Property owners across the Niagara region are pretty handy but some things are best left to the professionals. Some chores are more complicated than others, like roof or gutter cleaning, but when it comes to glass, you are dealing with delicate materials, heights and the threat of property damage. Leave pressure washers in the shed and spray bottles under the sink, and opt for professional care for your home or business.

    For many homeowners, their window washing consists of spraying basic cleaners with paper towels and hoping for a streak-free shine. Not only does this not get the best results, it ignores other important components like window frames and sills. Keeping these in good shape is just as important as caring for glass itself.

    Common questions

    Window Cleaning — answered

    What if I don't have an outdoor water source?

    A missing outdoor tap does not stop the job. We carry water in tanks for exactly these situations, so the work goes ahead as normal. The one thing we ask is a heads-up at booking, so the right crew shows up equipped.

    What about old single-pane windows?

    Single-pane windows clean with standard technique, but older ones get a careful eye. Aging glass can carry chips, cracks, or hardened mineral deposits, and the surrounding glazing putty may be cracked or loose. We clean them normally and flag any damage or weak points we notice during the visit.

    Can you reach my second-story windows?

    Yes. Second-story windows are routine. Water-fed poles reach up to six stories from the ground, and ladders handle most second-story work where footing allows. Crews choose between the two based on access and ground conditions, switching to specialty methods only for anything higher.

    Will my windows look better immediately after cleaning?

    The improvement is immediate and obvious, with hard water, dust, and bird droppings clearing dramatically. One honest caveat: long-standing hard water can etch glass over time, and while cleaning removes the deposits, deeply etched panes may not return fully clear.

    Are your cleaners safe for pets?

    In St. Catharines, our pet-safe biodegradable detergents are fine around animals, and we ask that pets stay indoors during service. That is mostly for their safety around open gates, ladders, and hoses while crews work, not because of the cleaners.

    What if I have specific windows I want focused attention on?

    In St. Catharines, just name the windows that matter most when you book, whether it’s a picture window facing the street or panes with built-up grime. Our crews note the priorities and plan the visit so those get the focused attention you want.

    Should I worry about post-cleaning weather?

    It helps to separate two things. Ordinary post-cleaning weather, light rain, fog, or dew, has no real effect on a properly cleaned pane. Damaging weather, hail or windblown debris from a storm, is a property concern in its own right and would harm glass regardless of cleaning.

    Do you use detergents or chemicals?

    We use professional window cleaning detergents that are biodegradable, plant-safe, and formulated for glass so they cut grime without streaking. On height work, pure water systems often run detergent-free, since deionized water cleans and dries spot-free on its own. The method is matched to the soiling.

    Can you clean awning windows?

    Yes, awning windows clean with standard technique. Hinged at the top, they open outward from the bottom, so the crew opens them to reach the exterior glass. They’re often set higher on the wall, above other windows, which can call for ladders or poles depending on placement.
