So you had your windows cleaned but they still look dirty. Then you realize what you see is actually between the panes and it isn't possible to even get to it. If multiple-pane windows appear misty or foggy, it means that the seal protecting the window assembly has failed.
Double-pane windows have a layer of gas (usually argon or air) trapped between two panes of glass that acts as insulation to reduce heat loss through the window. Other types of gas used in this space have various effects on heat gain or loss through the window. Some windows also have a thin film installed between panes that separates the space between the panes into two spaces, further reducing heat loss and heat gain through the window.
Although double-paned windows appear to be stable, they actually experience a daily cycle of expansion and contraction caused by thermal pumping. Sunlight heats the airspace between the panes and causes the gas there to heat up and expand, pressurizing the space between the panes. At night, the window cools and the space between the panes contracts. This motion acts like the bellows of a forge and is called thermal pumping.
Over time, the constant pressure fluctuations caused by thermal pumping will stress the seal. Eventually, the seal will develop small fractures that will slowly grow in size, allowing increasing amounts of infiltration and exfiltration of air from the space between the panes.
According to industry experts, the glazing assembly can be replaced approximately 75% of the time. Occasionally, the sashes must be replaced, and only about 5% of those cases require that the entire window be replaced.
In summary, condensation in double-paned windows indicates that the glazing assembly has failed and needs repair or replacement. Visible condensation can damage glazing and is the main indication of sealant failure.
When hiring an individual or team to come perform a service or task at your home... you may find yourself concerned with a number of scenarios. What if they steal something? What if they break something? How do I know they won't harm my family, pets or valuables? If they get hurt while working on my house... am I liable?

Why do we clean windows? Beyond the obvious reasons, the most important reason for glass maintenance is to avoid degradation. Glass will, over time, become permeated with a variety of contaminants.
WHAT CAUSES DEGRADATION?
1. HARD MINERALS (FROM SPRINKLER SYSTEMS AND RUN-OFF)
2. OXIDIZATION (FROM METAL FRAMES AND SCREENS)
3. ACID RAIN
4. OVER SPRAY (PAINT, CHALKING, MORTAR, ETC.)
5. SALT (FROM ROADS AND DRIVEWAYS)
Regular cleaning to exterior window surfaces (a recommended twice a year) will help you to avoid replacing your windows! Glass is a porous substance. Without cleaning, airborne pollutants can easily penetrate the surface, causing a transparent, dirty look.
Without maintenance, your windows may become permanently damaged.
Pure Water Simplified
Creating pure water involves a four-stage filtration and separation process utilizing carbon, sediment, a reverse osmosis membrane and deionization filtration to purify ordinary tap water and produce mineral-free water.
Pure water makes cleaning chemicals more efficient and effective by eliminating the need for the chemicals to treat the water and apply all of its cleaning energy to dissolve and carry the soil that needs to be removed.
Pure water is not found in nature; it is unstable in a sense, carrying with it pent up cleaning energy to solubilize soils and other contaminants it comes in contact with.
The result from cleaning with pure water as opposed to a mineral-laden liquid is spot-free windows.
Some specialized systems have been developed that provide high-volume pure water to clean windows up to five stories safely from the ground.
Using special water-fed poles from the ground eliminates the need for ladders and other equipment used to reach high windows, allowing one to clean windows in a fraction of the time it would normally take.
We are pleased to offer our customers this method of cleaning windows, which is cleaner, safer, and longer lasting.
Did you know maintaining your windows will add to the look and value of your home. It's important to clean your windows at least twice a year to ensure window maintenance. This is especially important for the exterior windows. By performing regular window cleaning tasks, you ensure that your windows will have a long life. Many environmental contaminants, such as acid rain, hard water, and oxidation, can damage windows over time. When you regularly clean your windows, you remove the materials that could cause the glass to break down or become weaker. If you are ever to sell your home, inspectors do take into account how well maintained the home is, and yes that includes the windows. Having sparkling clean windows WILL add to the curb appeal of your home. If they seem to need replacing, potential buyers will see this as a red flag. If you think of it this way, cleaning your windows is a solid investment for resale.
