Doesn't rain make my windows dirty?

Dirt makes your windows dirty not rain. The dust from landscapers, tree pollen, exhaust, and many other sources settles on your windows. Rain drops move the dirt around your windows and after the rain dries the dirt remains on the glass. This residue is now very visible because it's been spread over the window. Clean windows remain clean after the rain because once the water dries there is nothing left behind to obscure your view.

Weather Policy:

What if rain is predicted for the day of my window cleaning service?

It is our policy to complete a scheduled job if it is raining. In the event of light precipitation we will continue as scheduled because rain does not affect the cleaning. In the event of heavy rain or showers, we will return within 1 to 2 days to complete the outside work. The interior of all windows are completed as scheduled so there is no disruption to your schedule.

What if the forecast predicts High winds for the day of my appointment?

Safety is always our number one priority. Our standard states that we can work in up to 20 mph sustained winds, however, we seldom allow work to continue in such conditions. Our operations manager and crew leaders will evaluate the wind on site and determine if safety or quality will be compromised. We look at weather forecasts many times throughout the day to help determine safe working conditions for all of our employees. Depending on the size and location of your building we may be able to continue work out of the wind. You will be contacted with scheduling updates and cancellations as needed.

This technology that is another valuable tool to the window cleaning industry. We are able to offer ladder less window cleaning services using Deionized / Purified Water technology Using a water fed pole system. With the DI process, impurities in ordinary tap water are completely removed and the water becomes an aggressive cleaning agent without the use of detergents or chemicals. Purified water is pumped through specially designed extension poles with high tech brush heads that work together to clean your windows up to 8 stories high right from the ground! That means we can safely clean hard to reach and inaccessible areas outside without the use of ladders. This is great for OSI Certified and ‘Green' properties as it eliminates your risk of liability from ladders or staging equipment.

Energy Efficiency

Why should I buy vinyl instead of wood, fiberglass or aluminum windows or doors?

Vinyl is virtually maintenance free and color-fast. Vinyl products offer the energy efficiency of wood and fiberglass but generally at a lower cost. While the initial cost of aluminum products can be less expensive than vinyl, the overall cost of ownership can be much higher because aluminum does not offer the energy efficiency that vinyl does. Vinyl does not rot, corrode, rust or peel. It is insect resistant, does not need painting and is significantly more thermally efficient than either steel or aluminum windows.

Who tests and certifies our manufacturer's windows and doors?

There are two types of testing done on all our window and door products.

One type of testing includes standards and requirements set forth by AAMA/ANSI (American Architectural Manufacturers Association/ American National Standards Institute) which includes structural, air infiltration and water penetration. The tests are performed by accredited independent laboratories. The results are then administered and certified by Keystone Certification Inc., an ANSI accredited, licensed, independent certification agency. The products are then labeled with the appropriate AAMA certification labels.

The second test is for the thermal value standards and requirements set forth by NFRC (National Fenestration Rating Council). These test requirements are for the u-value, the solar heat gain coefficient, the visible light transmittance, and the condensation resistance factor. The tests are performed by accredited independent laboratories. The results are then administered and certified by Keystone Certification Inc., an ANSI accredited, licensed, independent certification agency. The total window or door thermal ratings are printed on NFRC labels and adhered to each product.

What will make a window more energy efficient?

A vinyl window or door by its nature is an extremely energy efficient product. Since vinyl is nonmetallic, it is inherently more thermally efficient than other products on the market. The conduction of heat through a vinyl window is minimal compared to windows made of aluminum or any other metallic substance. Vinyl's thermal properties and insulating values make it an excellent choice for use in cold climates as well. A glass package can be added to the window or door that includes options such as a Low Emissivity glass with TrueWARM® Structural Foam Spacer that increases the efficiency of the complete products as certified by NFRC.

What is Low Emissivity glass (LowE, LoE)

Specially designed coatings, often based on metallic oxides, are applied to one or more surfaces of insulated glass. These coatings reflect radiant infrared energy, thus tending to keep radiant heat on the same side of the glass from which it originated, while letting visible light pass. This often results in more efficient windows because: radiant heat originating from indoors is reflected back inside, thus keeping heat inside in the winter, and infrared radiation from the sun is reflected away, keeping it cooler inside in the summer.

What kind of Low Emissivity glass does Reflection windows and Doors offer?

LOW E2 Insulated Glass System features Low Emissivity glass coated with dual microscopic layers of silver, combined with TrueWARM® Structural Foam Spacer, Argon gas fill to create a dual sealed glass unit with superior energy efficiency and long term durability.

LOW E3 Insulated Glass System features Low Emissivity glass coated with a microscopic 12 layer patented formula with three layers of silver, a dual seal TrueWARM® Structural Foam Spacer, Argon gas fill and innovative Neat® coating that lets nature clean your windows. This option provides the ultimate balance of energy savings, solar control and high visibility.

What is Neat® coating?

Titanium Dioxide layer that reacts with the sun to decompose organic materials on the glass. A Silicone Dioxide layer creates an ultra smooth surface and hydrophilic action to disperse water evenly or “sheet off”.

How do I know if my windows or doors are being installed properly?

Even the best manufactured product must be installed properly (plumb, level and square) to insure proper operation and maximum thermal efficiency. Do your homework to make sure you are hiring a qualified installer. Check with friends and family, go on line to the contractor licensing board and check with other agencies to make sure the installation company you are hiring is qualified. If you have doubts about the installation, talk to your contractor about your concerns directly.

If I have a problem with my windows or doors, how do I go about getting it fixed?
