Frequently Asked Questions

Window Replacement (FAQ)

What Are Replacement Windows?

Replacement windows, also known as window replacements, are new windows installed in the existing openings of your home to replace old or inefficient ones. This process is essential for enhancing your home’s energy efficiency, aesthetic appeal, and comfort. Unlike new construction windows, replacements are designed to fit within the current structure, eliminating the need for extensive alterations.

Vinyl windows surpass traditional wood windows in durability, energy efficiency, and maintenance requirements. Wood windows, while offering a classic aesthetic, demand frequent upkeep, such as painting, and are susceptible to weather-induced damage like warping and rotting. Vinyl, on the other hand, is resilient against such elements, requires minimal maintenance post-installation, and contributes significantly to your home’s energy efficiency, making it a preferable choice for modern homeowners.

Energy-efficient windows are engineered with advanced features, including double or triple-pane glass, low emissivity (low-E) coatings, and inert gas fills like argon, which work together to minimize heat transfer. This insulation capability helps maintain a consistent indoor temperature, reducing the reliance on heating and cooling systems and, consequently, lowering energy bills.

Absolutely. Installing new, energy-efficient windows can markedly improve your home’s energy efficiency. These windows minimize unwanted air leakage and thermal transfer, cutting down the energy consumed by heating and cooling systems. The result is not only reduced energy bills but also an overall enhancement in comfort and a stable indoor climate.

In choosing new windows, evaluate the energy efficiency ratings, notably the Energy Star certification, and the window materials, including options like vinyl, wood, and fiberglass. Consider the style (e.g., double hung, single hung, casement, awning) and additional features such as grille patterns, exterior colors, interior blinds, and whether the windows open outward for ventilation. Assess the comprehensive cost, factoring in the installation, to ensure the project aligns with your financial planning.

The investment in window replacement varies widely, influenced by the window’s design, dimensions, material composition (vinyl, wood, fiberglass), and the intricacy of the installation. Vinyl windows are typically a cost-effective option, offering substantial energy savings and lower maintenance over time. For an accurate assessment tailored to your project, it’s advisable to consult with your installer for a detailed quotation.

The 3-person team arrived on time ready to go. Quietly and efficiently, they installed 5 windows in about 4 hours, a very professional job. And then they cleaned up afterwards. I purchased top of the line windows; the purchase price and installation were a great investment. Had windows installed in another part of my home by that other company that begins with an A, you've seen the commercials. They did a good job, but I got a better value with Keystone Window, without question. High quality windows, great price, professional installation. One other thing, the time from contract inception to installation was about 6-weeks vice 3 months with the other company. So, if your considering replacement windows, don't overlook Keystone Window. You won't be disappointed.John Weidemann ★★★★★ The installation was done with precision and expertise. The windows themselves were solid and very easy to open and close.
