How Installing Energy-Efficient Windows in Las Vegas Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, such as:

• Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
• Reduce your carbon footprint: In Las Vegas, you can reduce your indirect greenhouse gas emissions by about 468 pounds per year after you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in Las Vegas

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

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. These figures vary depending on specific characteristics of your installation, including number of windows, material, the location of your home, size, type and more.

It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Las Vegas home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your provider will have: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. These installations are more involved and will increase the overall cost. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Las Vegas, the decision will mostly depend on the efficiency of your home and how old your existing frames are.
