20 Best Window Companies in Lexington, SC (2025 Reviews)

How Installing Energy-Efficient Windows in Lexington Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $385 annually on your energy bills in Lexington.

Estimated Cost of Window Replacement in Lexington

Each window installer offers varying services and has varying price points based on a few factors.

How Much Do New Windows Cost?

Generally, Lexington homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost varies based on several factors, including material, type, the location of your home, size, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lexington homeowners $385+ each year after replacing single-pane windows.

Costs will also vary based on the material of your frame. 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 cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When considering window replacements, 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 full window, including the trim, sill and frame. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In Lexington, the decision will mostly be based on how much damage there is currently and the condition of your existing frames.
