Why Window Installation Matters
No Short Cuts
Washington Energy Services takes the philosophy of quality over quantity when it comes to your window installation. We apply the nail-fin application because it allows us to use the nail fins on the sides of the windows to push flat against the house for extra support while serving as a moisture vapor barrier.
The flange gives us a solid platform to secure the window to the home from the front, flat against the house.
Short cuts taken by other window replacement companies will often cut the nail fins off. Doing so pushes the frame in the pocket. This forces 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 installation the correct way means we can install only 7 or 8 windows in a day. However, you can ensure a quality window installation so you’re windows will stay strong for years and years to come.
Keeping it in the House
We do not use subcontractors to install your windows. Your lovely new windows will be professionally replaced by employees of Washington Energy Services. We only hire the best employees who must be licensed, bonded and drug tested. We believe in continuous training to ensure high standards and quality window replacements.
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?
This can be a sign that window replacement should be undertaken. Leaky windows are caused by several factors; improper installation, aging of certain window frame materials, or lack of caulking and care. Water can sneak it’s way into your home, showing up as condensation between panes of glass or it can go around windows and 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 making for poor insulation. This allows for a hot home on hot summer nights and a drafty home in the cold winter nights which ultimately costs you not only money but discomfort as well. These old style frames are especially difficult to find now-a-days because Seattle consumers have learned of their poor performance. Aluminum windows are getting removed and replaced slowly but surely from our Northwest homes. Most electric utilities offer significant rebates for the replacement of aluminum windows if you have electric heat in your home. They value the energy savings from new energy efficient windows as much as you will.
Single Pane Glass
According to ENERGY STAR, replacing single-pane windows for a typical home with an ENERGY STAR rated window can save you from $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.
The type of window in your home plays a big role in noise transmission. Living near a busy street or a noisy neighborhood can make for lost sleep. Our noise reduction windows are created using advanced technology to reduce sound transmission. Seattle and Tacoma city homes or those near airports especially need noise barriers such as triple pane window glass, for families to enjoy peace and quiet.
Fading Furniture, Carpets & Drapes
Older Washington windows allow ultraviolet rays to beam through the windows causing the fabrics in your home to fade in color 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.

What is the most popular Seattle window type and why?
Older Seattle Windows
Most older homes have either wood or aluminum framed windows. Traditional wood windows can be beautiful if maintained, however sealing, staining or painting plus occasional refurbishing (sanding, new coats etc), is required. Wood windows are prone to rot, and in our climate moss can eat away at them and speed that rot. Moss is not just a green coating, when it’s removed you can see how it takes a bite out of surfaces, even pitting driveways. Once they rot, they will not take paint or stain as well and will degrade further over time.
Aluminum windows conduct heat and cold. The heat seeps out through the sash and frame, making them energy losers in our climate. The older aluminum single paned windows, without thermal breaks, are so energy inefficient that electric utilities are paying significant rebates to replace them. If you are interested in the durability of a metal frame exterior, but with energy efficiency and a nice interior, wood-clad windows now provide a great alternative. The wood-clad windows we provide are Anderson E-Series wood-clad windows. They have beautiful wood on the inside and the outside has a layer of durable metal to protect against weather.

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.
Why all the info about finished? The height is very important as it is what will allow people to get up and out of the window. The sill and floor when unfinished could have a difference in height vs finished of up to an inch depending on things like flooring, carpet, sill material, trims etc. This is what the inspector will be looking for when they come to sign off.
What does Low E mean?
There are levels of Low E coating, eg: double Low E, triple Low E, these increase the energy efficiency of the window. To see how this works, go to our Vinyl windows page and compare the Signature Window to the Classic window. You’ll see that while both are EnergyStar rated energy efficient windows, the Signature, with triple Low E has a lower U value (more efficient).

U-Factor and other common window replacement terminology explained
Here are some other terms and brief window definitions:
- Casing: The trim applied around the interior or exterior window opening to cover the gap between the frame and the wall is called casing. This is also known as face trim.
- 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 indicate 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 and if this happens, just give us a call.
- 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 protection from weather and insulation as well.
- NFRC: The National Fenestration Rating Council. (Okay let’s stop and define Fenestration – that’s a fancy word for openings in your house including both windows and doors.) . This is the government agency that standardizes testing on windows and doors and rates them for efficiency. The NFRC labels provide the rating number so you can compare windows.
Here’s a fake NFRC label that comes from the NFRC website to demonstrate what they measure. You will note U Factor. We don’t have a huge amount of solar heat gain (SHGC) in the Northwest to worry about, so 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 better the product is at keeping heat inside. The other measures are visible transmittance, or how much light makes it through from the outside and air leakage, how much outside air can get in through this window. Good air leakage ratings fall between .1-.3.
- Picture window: A picture window is one which does not open, and is also called a fixed window.
Sash: A sash is the operating part of the window, that opens and closes it.
- Seal: The seal is what keeps an insulated glass unit (IGU) closed to outside contaminants, and for energy efficient windows, keeps the argon gas inside. It is the combination of a sealant material and a spacer component.
- Single hung: A single hung window slides open vertically, lifting up from the bottom. A Double hung window opens vertically from the top and from the bottom.
