Older homes throughout the Pittsburgh area are known for their character, craftsmanship, and unique architectural details. From historic brick homes in Squirrel Hill to traditional homes in Mt. Lebanon and older neighborhoods throughout Western Pennsylvania, these properties often feature designs that homeowners want to preserve.
When it comes time for home window replacement, choosing the right replacement windows requires more than selecting a style that looks attractive. The windows need to complement the home's architecture while improving comfort, energy efficiency, and long-term performance.
Modern Pella windows provide homeowners with options that combine traditional appearance with today's advanced technology. With the right window selection and professional installation, older homes can maintain their original charm while gaining the benefits of improved insulation, easier operation, and reduced maintenance.
For more than 90 years, Gunton Corporation has helped homeowners throughout the Pittsburgh region choose and install Pella windows designed to meet the unique needs of older homes.

Understand Your Home's Original Design
Before choosing replacement windows, it is important to consider the architectural style of your home. Many older Pittsburgh homes were designed with specific window proportions, layouts, and details that contribute to their overall character. Replacing those windows with styles that do not match the home's design can affect the appearance of the property.
Traditional homes often pair well with classic window styles such as double-hung windows, which maintain the look many homeowners associate with older architecture. Colonial homes, Victorian properties, and brick homes throughout neighborhoods like Sewickley and Mt. Lebanon often benefits from replacement windows that preserve symmetrical designs and traditional details.
For homeowners with historic properties, maintaining the original appearance may be especially important. Modern Pella windows are available in a variety of styles and finishes that allow homeowners to improve performance while respecting the home's existing character.
Consider the Condition of Your Existing Windows
The condition of your current windows plays a major role in determining the best replacement approach. Some older windows may have problems that go beyond appearance. Drafts, difficult operation, moisture between glass panes, damaged frames,
and deteriorating finishes can all indicate that replacement may be the best solution.
Homeowners should also consider how often their current windows require maintenance. Older wood windows may need regular painting, scraping, or repairs to keep them functioning properly. Today's replacement windows are designed with improved materials and finishes that reduce maintenance requirements while providing better protection against weather conditions.
A professional evaluation can help determine whether your home needs replacement windows or if repairs can extend the life of your existing windows.
Choose the Right Window Material
Window material is one of the most important decisions during a home window replacement project. Different materials offer different advantages depending on your home's age, style, and performance goals.
Wood windows remain popular for historic homes because of their natural beauty and authentic appearance. Many homeowners appreciate the warmth and craftsmanship of wood, especially when preserving the traditional character of an older property is a priority.
Fiberglass windows offer excellent durability and energy efficiency. They resist warping, swelling, and temperature changes, making them a strong option for Pittsburgh's changing seasons. Fiberglass windows also provide the strength needed for larger glass areas while requiring minimal maintenance.
Vinyl windows can provide a cost-effective option for homeowners who want improved efficiency and low maintenance. They are available in many styles and can be a practical choice for certain homes depending on design goals and budget. Choosing the right material depends on balancing appearance, performance, maintenance expectations, and long-term value.
Improve Energy Efficiency Without Losing Character
Many older homes were built before today's energy-efficient window technology was available. Single-pane glass, aging seals, and older framing systems can allow heat to escape during Pittsburgh winters and contribute to unwanted heat gain during summer months.
Modern Pella windows are designed with features such as Low-E glass coatings, insulated glass packages, argon gas between panes, and advanced weatherstripping to improve thermal performance.
These improvements help reduce drafts, maintain more consistent indoor temperatures, and create a more comfortable living environment. For homeowners who love the character of older homes but want modern comfort, replacement windows provide a way to achieve both goals.
Select Window Styles That Fit Your Home
The style of replacement windows should support both the appearance and function of your home. Double-hung windows remain one of the most popular choices for traditional homes because they offer a classic appearance and practical ventilation. Their vertical design works well with many older architectural styles throughout Pittsburgh.
Casement windows provide excellent ventilation and energy efficiency because the sash opens outward and creates a tight seal when closed. They are often a good choice for homeowners looking for maximum airflow and unobstructed views.
Picture windows can add natural light to living rooms, dining areas, and spaces where homeowners want larger views of the outdoors. They are often combined with operating windows to create both beauty and functionality. A combination of window styles throughout the home can provide the right balance of appearance, ventilation, and performance.
Installation Matters as Much as the Window
Choosing high-quality replacement windows is only part of the process. Proper installation is essential for achieving the expected performance. Older homes often present unique challenges, including uneven openings, original trim details, and settling that has occurred over many decades. Experienced installers understand how to work with these conditions while protecting the home's structure and appearance.
Professional installation helps ensure windows are properly sealed, aligned, and insulated. This reduces the risk of drafts, moisture issues, and future operating problems.
