Care & Maintenance


This Care & Maintenance Guide

While your Cascade vinyl windows and doors require little care and maintenance, it is recommended that you clean and inspect them at least once a year to keep things operating smoothly and to protect your warranty. This brochure outlines how to go about keeping your windows and doors properly cleaned and maintained.

Glass Care

Regular cleaning of your insulating, low-e or heat reflective glass is a relatively easy, this is an important part for maintaining their effectiveness and to ensure the best performance over the life of the product.

Frame Care

Protecting the frames of your windows and doors is just as important as cleaning the glass. While the vinyl or aluminium material naturally prevents penetrating stains from dirt and grease, it is still important that you clean and maintain to protect the life and extend the beauty of your windows and patio doors.




Cleaning and lubricating the window track twice a year is suggested for easy operation.

Painted Frame Care

Our painted vinyl products are painted with a superior painting process that is highly durable and requires the same maintenance as our standard frames. However, it is best to remove contaminates and debris as quickly as possible. Soap and water are recommended.

Hardware Cleaning and Lubrication

Hardware parts, tracks and rollers should be inspected and lubricated annually. More frequently if in high moisture or a salt air environment.

Silicone Spray Can

We recommend a dry silicone spray for lubricating tracks.



Screen Care

Because our screens are made of advanced materials, it is not necessary to remove the screen for the initial cleaning. You can simply vacuum clean or gently wipe down with water and a soft cloth. For a more detailed cleaning:

Note! Screens are not covered under Cascade's Lifetime Warranty.

Sliding Patio Door Roller Adjustment
To adjust the patio door rollers for proper height clearance, remove panel plugs to access the adjustment screw. Simply turn the screw to adjust the vent either higher or lower and replace the plug when finished.

Patio Door Care

Most moving parts, including window and patio door vent panels, require annual inspection and lubrication to ensure smooth and easy operation. In high moisture or salt air environments, more frequent cleaning and lubrication is necessary.



Patio Door Adjustment

Patio Door Lock Adjustment

You may need to realign your strike plate with the frame panel lock if you have made any vent panel adjustments. Locate the strike plate screw and turn for proper alignment and test that the door locks securely.

Water Management

Weep System

Vinyl and Aluminium windows and patio doors are not subject to moisture damage; however, damage could develop in the structure around the unit if water does not drain properly from the sill area to the exterior. A simple drainage system of "weep" holes are designed into the frame to allow for accumulated water to drain to the exterior of the dwelling. While it is normal to see some water in the bottom track or sill with wind driven rain, these water drainage pathways must be kept clean and clear of obstructions to operate effectively and to ensure no water infiltration into your home.

Little Girl Looking Out The Window

Interior Condensation

The interior of windows can encounter condensation due to high humidity levels and poor air flow in a home. High efficiency, high-performance windows are weather tight, but this also reduces air circulation.

In order to reduce the likelihood of window condensation, take these steps in your home:

Other Condensation Factors:

Exterior Condensation

Summer condensation occurs when the outside window surface is cooler than the dew point temperature of the outside air. This is a natural occurrence.

Glass Breakage

If the glass in a Cascade window gets broken, consult your Cascade Window dealer for assistance. We recommend that glass panes be replaced by a professional to ensure continued thermal performance and to address safety issues.

Tempered Glass

Tempered glass can handle impact better than ordinary glass, but it can break. If a tempered glass pane is broken, it should be replaced by tempered glass in accordance with local building codes.

Difficulty Opening or Closing the Sash

If you experience difficulty in opening or closing the sash on Cascade casement or single-hung windows, first make sure that the lock handle is completely disengaged. By slightly turning the handle and applying pressure to the sash, the sash should open normally.

If this does not solve the problem, make sure that dirt or debris is not blocking the slider track. To remove any debris, clean the track with soapy water and a small brush (an old toothbrush works well.), or with a vacuum cleaner. After the track is clean, you may want to lubricate it with a dry silicone spray.

If the sash drags or hits the window frame, your window is out-of- square. Contact your Cascade Window dealer for assistance.

Window Coverings

Coverings installed too close to the glass can cause the glass to crack, the seal to fail, or develop excessive condensation on the glass. When installing blinds, leave a minimum of 2" clearance between the glass and shading device, and 1-1/2" clearance at the top and bottom or one side and bottom to allow natural air movement.

Climate and Condensation

If you live in a colder climate, warmer, more humid indoor air, compared to the temperature outside, can cause water droplets, frost and even ice to form on the inside of your windows.

More specifically, condensation occurs when the temperature of a surface – in this case, your windows – is less than its dew point temperature. The dew point temperature varies for every surface, and windows are more susceptible to condensation than other household surfaces because they tend to be the coldest part of a house. What's more, as the relative humidity (the amount of moisture in the air) of a room increases, the dew point temperature of surfaces increase as well.

For example, when the temperature of the glass in your window is 45˚F and its dew point temperature is 50˚F, the result is condensation. The condensation will only evaporate when the window temperature rises to about 50˚F. In addition to obscuring your view, condensation can also do visible and invisible damage to your home. Curtains, carpets, and even the windows themselves can be affected. The structure of your home can also be compromised as moisture may permeate your walls and insulation.

A Difference "U" Can See

The good news is not every window is the same. As you have learned, increasing the temperature of the glass above its dew point temperature will eliminate condensation. On a cold day, when you would normally be heating your house, it is important to decrease the transfer of that heat through the window.

This is known as the U-factor; the thermal transmittance of the window. The lower the window's U-factor rating – typically between 0.20 and 1.20 – the less warmth escapes your house, resulting in a decreased possibility of condensation forming.

The U-factor of any window product is actually determined by several factors, which work together to keep the glass condensation-free.

Your Three-tiered Solution

The windows in your home are made up of three essential parts, each one with the potential to eliminate condensation inside your home. All three must be thermally efficient to prevent heat from being conducted out:

Center-of-Glazing Multiple-glazed windows or insulating glass units are recommended over single-glazed windows for keeping condensation at bay. Additionally, energy-efficient and low-e coatings will further reduce the potential for condensation. Edge-Of-Glazing Condensation on the edge-of-glazing can likewise be reduced by choosing high performance dual-glazed or insulating glass units over single-glazed windows. Frame Thermally improved framing materials such as vinyl and wood, instead of metal framing systems, reduce the chance for condensation formation.
