How Installing Energy-Efficient Windows in Lewiston Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 163 pounds per year on average.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Lewiston

When researching window installation, each company offers varying services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Generally, Lewiston homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will make your project cost more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lewiston homeowners $411+ a year after replacing single-pane windows.

Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window installations, there are generally two types that your provider will have: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. A pocket installation involves replacing a window without removing the complete frame, which is usually cheaper than a full-frame installation.

Your window replacement company should be able to help you understand what’s best for your needs. In Lewiston, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.
