Window Cleaning Questions

When cleaning your windows in the winter, the first thing you should consider is the weather prediction for the day of your cleaning an d the days following. Choose a day when the weather isn’t too hot or cold, and the wind isn’t howling. The next step is to figure out what time of day is ideal. Clean your windows in the shade or on cloudy days to avoid streaks, especially during the winter. Lastly, when it comes to the temperature of the water you use to clean your windows, you must be cautious. Use warm water whenever possible.

Any season is a good time to clean your window, however, spring is the most popular season for window cleaning. A summer day is also a great time to clean your windows because of the quick-drying period and low chance of rain. The weather in autumn isn’t too hot, so cleaning materials are less likely to dry out and leave residue on your windows, and you can also have your gutters cleaned too. Getting your windows cleaned in the winter, despite the fact that it’s the rainiest season, is an incredibly good idea since clean rain won’t actually add much dirt to your windows.

Cleaning windows on a hot, bright day is not a good idea since everything dries faster and the window streaks. The best time to clean would be on a cloudy day.

It’s better to stick to simple cleaning solutions. Avoid using ammonia or alcohol-based glass cleaners as they can leave streaks and even a thin film that attracts dust and moisture.

Instead, fill a bucket halfway with warm water and a drop or two of dishwashing liquid. Make sure to scrub down the corners, creases, and crevices before washing the window.

Use a sponge and wet your window with the solution from your bucket. To avoid streaking, you’ll want to accomplish this as quickly as possible. To get rid of any streaks after squeegeeing and make your windows shine, use a dry cloth or newspaper as this is the best method to clean windows without streaking.

It is important to prepare the pressure washer adequately so that you do not crack the glass or loosen the wood putty when you are cleaning your windows with it. Use the right nozzle and set the correct pressure.

We recommend you use no more than 2000 (PSI) on your pressure washer. You should set the pressure to 1,500 psi. Secondly, you should choose a 40-degree or 65-degree nozzle, as you don’t want to spray water directly on the window pane.

Use the right cleaning detergent. You need detergent made for pressure washers. Fill up the reservoir in your pressure washer; when it is running, the detergent will mix with the water to create the right proportion.

Spray it at an angle. You should avoid spraying water directly at the window even with the wide nozzle and low pressure.


Eavestrough & Gutter Cleaning Questions

Eavestrough fills with leaves, roof debris and dirt as the seasons’ change. Your eavestrough can become clogged if it is not taken care of properly. Clogged gutters can cause many problems and damage to your basement, siding, roof, gutters, and more. Ice damming can occur as a result of ice filling in the gutters. When snow and ice melt off the roof, there’s nowhere for the water to go but over the gutter. Gutters clogged with leaves and debris become quite heavy, especially when wet, causing sagging to the eavestrough and resulting in damage costs. 

Gutters are an essential part of the roofing system and are designed to protect your home inside and out from water damage. If your gutters and spouts are clogged and aren’t clean you will have an overflow of water that will lead to damages to your fascia board, walls, ceilings, foundation and even cause flooding to your basement.

Mold and mildew build up over time due to constant water overflow and they can be costly repairs to your home and can affect your health.

Depending on how quickly the ice melts and whether your downspouts are also full of ice, the water may not have anywhere to go. The ice can cause damage to your gutters, fascias, soffits, and more.

Water can also collect under your shingles. Damaged shingles can potentially cause your roof to leak. When water freezes and condenses in your gutters, it expands. The weight of the ice can cause your gutters to break, burst and even be misaligned.

Gutters clogged with ice can result in ice dams. Ice dams can produce icicles or they can back up onto your roof. This can lead to too much weight at the edge of your roof. Ice dams often damage the shingles on your roof, which means that you’ll have water in your attic, which could damage insulation, wiring, and anything else in there.


A gutter’s primary function is to redirect water away from your property. Blocked gutters can lead to overflowing and water seeping down to the foundation of your property. The earth beneath your foundation can shift and crack because of the water. When your gutters are filled with debris, rainwater cannot drain and collects in the gutters. Any shingles exposed to water will decay more quickly than the rest of your roof. The longer your gutters are clogged and dirty, the more water will pool around the base of your home. Water will leak into your basement walls when it overflows and runs down the side of your house. Extra weight on your gutters will damage your soffits and fascia and cause your gutters to sag. Your gutters may fall off your property if left unattended for a long time. Some bugs and animals see clogged gutters full of leaves, debris, and standing water as a feast. These pests might get into your home through holes in your roof or foundation as the weather begins to cool.


Siding Cleaning Questions

Hand scrubbing is the most effective method for cleaning siding. Pressure washing is convenient and appears simple to use, but it can end up costing you money in the long run. Using a pressure washer can cause holes in your siding and peel paint off your home and can cause water to enter your home, accumulating within your attic, walls, and flooring, leading to mold and mildew growth if water enters where it shouldn’t. Hand cleaning the siding, in our experience, has proven to be the most effective in the long run.

Rainwater, as well as washing your siding with a garden hose, is a natural and easy way to clean vinyl siding. We recommend using microfiber cloths, a soft bristle brush or a broom to clean your vinyl siding because they will not scratch or chip the surface. Use a bucket to mix your siding cleaner. We recommend creating a solution to clean your siding. For tough dirt, dust, and grime, combine a general-purpose cleaner in a bucket with warm water. Make a solution of 70% water and 30% white vinegar if you’re trying to get rid of mold and mildew. To preserve the grooves in the texture stain-free, use only a soft bristle brush on textured surfaces.

Purchase trisodium phosphate powder (TSP) for washing wood siding by hand. It’s a strong cleaner that is found at most home improvement stores. Combine 1/4 1b trisodium phosphate powder in a gallon of water in a big bucket or container. If your siding is filthy due to sap, pollution, or other factors, add 3 cups of TSP to a gallon of water. If you’re fighting mold and mildew, mix 75 percent water and 25 percent white vinegar in a spray bottle. Mold and mildew can be killed with vinegar and can be used to remove stains. Wet a section of siding with your garden hose and scrub it with the solution. Apply the cleaning solution piece by section with a soft-bristle brush, scrubbing firmly enough to clean without harming the siding surface. Rinse off the solution and repeat the steps as necessary.

The exterior of your home is as important as the interior when it comes to selling your home. Consider what potential buyers see when they arrive at your home.  Hiring a cleaning service will allow the job to be completed on time and there will be less room for miscalculation. Professionals understand the best approach to exterior house cleaning and have access to the cleaning equipment used in the industry.

When looking around the house, potential buyers will often look out the windows to see what the view is like from the inside. You don’t want them looking out dirty windows because it indicates a poorly maintained home. A well-kept yard can increase the value of your home. A new door is always a nice touch, but if that’s not in the budget, a fresh coat of paint and new hardware on your old door will suffice.


General Questions

Professional cleaners, such as a window cleaning company, will typically examine what to clean on your structure, such as a complete diagnosis of the building in question. Professionals should be hired for exterior cleaning because they have an excellent array of equipment and a wealth of skilled and experienced labour to get the job done. Professionals’ systematic approach to their work saves time in the long run, as an experts’ due diligence in the investigation, procurement, and execution pays off. Accidents and injuries are common unless you have been doing this task for years. Don’t take any chances and hire professionals to clean your home’s exteriors instead.

Look for any potential obstructions in the region. If there are any cracks or splits, you should have your gutters replaced. Replace or touch up the paint on the gutter’s damaged area. Gutter sagging is a sure sign that gutters need to be replaced. Gutters must never sag or pull away from the structure.

Water damage beneath gutters may signal that the gutters are leaking or overflowing.

If you see standing water or mildew near the foundation, it can indicate that the gutters are clogged or a defect in the gutter system. Remove the clog. If the problem persists, replace that section of the gutter and downspout.

If it is exterior cleaning; please unlock all the gates so we can access windows or eaves trough. If it is interior cleaning; not much but if curtains and blinds are folded the job would go smoothly. If the job includes scrubbing of eaves or siding; we would need access to the hose, tap and water. We will take care of the rest!
