Why Window Installation Matters
No Short Cuts
Washington Energy Services believes in quality over quantity when it comes to your window installation. We apply the nail-fin application because it provides extra support and serves as a moisture vapor barrier.
Short cuts taken by other window replacement companies include cutting off the nail fins. Doing so pushes the frame in the pocket, forcing them to go inside the house to screw at a diagonal through the frame in order to secure it. This compromises the structure and weakens the frame. Be cautious of companies that advertise a fast installation.
A quality, correct installation from WES results in 7 or 8 windows installed per day. We take the extra steps to ensure every window is installed to last. Again, quality over quantity will always be our philosophy.
Keeping it in the House
We do not use subcontractors to install your windows. Your windows will be professionally installed by Washington Energy Services employees only.
In fact, we don’t even consider ourselves contractors. We’re craftsmen who are passionate about what we do.
Traveling Safely to Your Home
All windows are shipped with a protective film sealed to the glass to ensure they arrive smudge, scratch, and dirt free.
What signs or symptoms indicate I need new windows?
Leaky windows are caused by several factors: improper installation, aging of certain window frame materials, or lack of caulking and care. Water can sneak its way into your home, showing up as condensation between panes of glass, or under the siding, causing rot. This is especially problematic here in the Northwest. Excess moisture is the perfect environment for mold and mildew growth in your home, and of course, for leaky windows.
Aluminum Framed Windows
Aluminum window frames conduct heat rapidly, which results in poor insulation. This costly occurrence causes hot summer days and cold winter nights. These old style frames are becoming increasingly difficult to find and are slowly being replaced by more efficient solutions. Most electric utilities offer significant rebates for the replacement of aluminum windows if you have electric heat in your home.
Single Pane Glass
According to ENERGY STAR, replacing single-pane windows in a typical home with ENERGY STAR rated windows can save $146-$501 annually and 1,147-3,839 pounds of CO₂ (ENERGYSTAR.gov). In addition, upgrading to double or triple pane windows will increase your overall home comfort and security.
Windows play a big role in noise transmission, especially if you live near a busy street or a noisy neighbor. Those living near airports may especially want to consider noise barriers such as triple pane window glass to enjoy peace and quiet.
Fading Furniture, Carpets and Drapes
Older windows allow ultraviolet rays to beam through, which can cause fabrics to fade over time. Our Low E windows block up to 95% of the sun’s ultraviolet light to protect your valuables while still allowing natural light into your home.
Does Washington Energy Services do window installations in my area?
If you are considering replacement windows, our home energy specialists will help you evaluate the latest energy efficient fiberglass, wood-clad, and vinyl windows. Our no-hassle approach is to first consult with you on your options, and then provide top quality products and services tailored to your needs and preferences. Our long legacy of service speaks for itself.
Let’s get started.

What are the fire codes for new window installations?
- Minimum of 5.7 sq. ft of opening that is clear and accessible.
- With a minimum of 24 in. of clear height and 20 in. of clear width.
- And a finished sill height of 44 in or less above the finished floor.
The height is very important as it is the key indicator of one’s ability to get up and out of the window. The sill and floor, when unfinished, may have a difference in height over a finished sill and floor. An inspector will verify this before signing off on the room.
What does Low E mean?
There are varying levels of Low E coating, such as double Low E and triple Low E. These measurements pertain to the energy efficiency of the window. To see how this works, visit our Vinyl Windows page and compare the Signature Window to the Classic window. You’ll see that while both are ENERGY STAR rated windows, the Signature features triple Low E and a lower U value, resulting in a more efficient solution.
What is a mullion?
What is a casement window?
U-Factor and other common window terminology explained:
- Casing: Also known as face trim, casing is the trim applied around the interior or exterior window opening to cover the gap between the frame and the wall.
- Condensation: This is moisture that forms on a surface when it is colder than the dew point (temperature at which dew forms). The condensation can be on the outside of the window, which may be a function of other aspects of your home (for example, where your water heater vents) or on the inside of the window between the panes. The presence of condensation between glass panes is typically an indication that the seal of the window has failed. If your windows are still warrantied, this can be easily fixed by replacing the glass unit. Our Signature series vinyl windows have a lifetime warranty against seal failure.
- Deglaze: The deglazing process is removing the glass from the window frame.
- Double strength glass: 1/8″ thick glass is considered double strength.
- Lite: A “lite” is a single piece of glass or glass section within a window or a door.
- Nail Fin: The nail fin is a flange or strip on the sides of a window frame that is created when the frame is made to permit secure fastening of the window to a structure. We use the nail fin method of installing windows because the nail fin will fit tightly onto the house, providing greater insulation and protection from weather.
- NFRC: The National Fenestration Rating Council. (Fenestration refers to the openings in your house including both windows and doors.) This government agency standardizes testing on windows and doors and rates them for efficiency. The NFRC labels provide the rating number so you can compare windows.
This replica NFRC label demonstrates the various measurements. You will note U Factor. We don’t have a huge amount of solar heat gain (SHGC) in the Northwest to worry about. Therefore, U factor—a measure that translates to energy efficiency—will be most important to us. The U-factor measures how well the window keeps heat from escaping. The lower the U factor, the more efficient the product is at keeping heat inside. Another measure is visible transmittance, or how much light makes it through from the outside and air leakage. Air movement, or air leakage, is also measured. Optimal air leakage ratings fall between .1-.3.
- Picture window: A picture window, or fixed window, is one that does not open.
Sash: A sash is the operating part of the window that allows it to open and close.
- Seal: The seal is what keeps an insulated glass unit (IGU) closed to outside contaminants. For energy efficient windows, the seal keeps the argon gas inside. It is the combination of a sealant material and a spacer component.
- Single hung and double hung windows: Single-hung windows have only a lower operating sash for ventilation. Double-hung windows have two operating sashes that move up and down, allowing for ventilation on the top, bottom, or both.
