How Installing Energy-Efficient Windows in Bothell Saves You Money

When you switch to energy-efficient windows, you may see several perks, such as:

• Save on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Reduce your carbon footprint: In Bothell, you can cut your indirect greenhouse gas emissions by about 271 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Bothell

Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Even though the typical cost to install a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, such as type, material, size, the location of your home, number of windows and more.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Bothell homeowners $380+ per year after replacing single-pane windows.

Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations entail replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. Because these installations are more involved, they will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company will be able to help you understand what’s best for your needs. In Bothell, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.
