Thinking about replacing your windows with Pella? Whether you’re dealing with drafty windows, deteriorating frames, difficult-to-open sashes, or simply want to update the appearance of your home, choosing the right replacement windows makes a difference. At Window Installation Specialists, we’ve been installing replacement windows and doors throughout Pittsburgh and Western Pennsylvania since 1973, and we work with Pella windows and doors in wood, fiberglass and vinyl to help homeowners select products that fit their homes, preferences, and budgets.
Traditional
Pella Reserve and Architect Series bring custom shapes, grille patterns, and fine wood interiors to homes where historic character matters.
Contemporary
Pella Impervia fiberglass and modern Lifestyle Series options offer slim frames, expansive glass, and low-maintenance durability.
Pella Window Installation in Pittsburgh and Western Pennsylvania
Replacing windows involves more than selecting a brand and ordering the right size.
Many homes throughout Pittsburgh have older window openings, existing wood trim, or architectural details homeowners want to preserve. Some windows have been replaced before, while others may be original to the house. These conditions can affect how the replacement is handled.
Before ordering new windows, we evaluate the existing openings, discuss your concerns, and help determine which Pella products are appropriate.
For example, a homeowner in Sewickley may want wood windows that complement the home’s original interior trim. Someone replacing windows in a newer Wexford home may prefer fiberglass for its durability and lower maintenance requirements. The best option depends on the home and what the homeowner wants to accomplish.
Our installation crews are company employees, not subcontractors. We focus on proper measurements, installation, insulation, sealing, and finishing details.
Pella Replacement Window Options
Pella manufactures windows in several materials, giving homeowners different choices for appearance, performance, and maintenance.
Pella Wood Replacement Windows
Wood windows are often selected for their traditional appearance and the warmth they bring to a home’s interior. They can be a particularly good fit for older Pittsburgh homes, historic-style properties, and houses with existing woodwork that homeowners want to maintain.
Pella offers wood windows with a variety of interior finishes, exterior cladding options, grille patterns, and hardware selections. Depending on the product line, homeowners can choose traditional or contemporary designs.
Wood windows do require consideration of maintenance, moisture exposure, and the condition of surrounding trim. We help homeowners compare available wood window options and determine which products make sense for their homes.

Pella Impervia Fiberglass Windows
Pella Impervia windows are manufactured using Pella’s proprietary fiberglass material. Fiberglass is a popular choice for homeowners who want durable frames without the maintenance requirements associated with traditional wood windows.
Pella Impervia windows are available in several operating styles and finishes, making them suitable for both traditional and contemporary homes. Their relatively slim frame profiles can also appeal to homeowners who prefer a clean appearance with more visible glass.
We’ve worked with Pella Impervia products on local replacement projects, including an installation in Bellevue, Pennsylvania.
For homeowners comparing fiberglass with vinyl or wood, we can explain the differences in construction, appearance, and available features.

Pella Vinyl Replacement Windows
Vinyl replacement windows are another option for homeowners who want a low-maintenance product. They don’t require regular painting or staining, and Pella offers vinyl windows in various styles and configurations.
Vinyl can be a practical choice for replacing older windows in bedrooms, living areas, and other parts of the home. However, not every vinyl window has the same construction, glass options, or performance ratings.
We help homeowners compare the available products rather than selecting a window based on material alone.

Comparing Pella Window Series
Pella offers several product collections, each designed around different materials, styles, and homeowner preferences.
Pella Reserve
A premium wood window collection with traditional and contemporary design options. Homeowners often consider Reserve when architectural details, interior wood finishes, and customization are important. Depending on the selected product, options may include distinctive grille patterns, hardware, and exterior finishes. This collection may be worth considering for historic-style homes, custom residences, and projects where matching existing architectural details is a priority.
Pella Lifestyle Series
Pella Lifestyle Series windows offer wood interiors with protective exterior cladding. They can be a good option for homeowners who want the appearance of real wood inside their homes while benefiting from exterior protection. Available glass packages and other features vary by product configuration. Lifestyle Series windows are worth comparing when replacing traditional wood windows or updating a home where interior appearance matters.
Pella Impervia
Pella Impervia uses fiberglass construction rather than wood or vinyl. These windows appeal to homeowners looking for durability, relatively low maintenance, and a variety of contemporary or traditional configurations. They’re particularly worth comparing when you want the appearance of a slimmer frame without selecting a wood window.
Pella 250 Series
Pella 250 Series is a vinyl window collection offering several common replacement window styles. It may be an option for homeowners who prefer vinyl construction and want to compare glass packages, operating styles, and finishes.
We can help determine which Pella series and configurations are currently available and appropriate for your project.
Pella Window Styles for Pittsburgh Homes
Choosing a window material is only part of the decision. The way a window opens and its overall design can affect ventilation, cleaning, furniture placement, and the appearance of the house.
Double-Hung Windows
Common in traditional Pittsburgh homes. Upper and lower sashes move vertically, providing ventilation without a sash projecting outward. Frequently chosen when replacing older double-hung wood windows.
Casement Windows
Open outward using a crank. Often selected for kitchens, living areas, and spots where homeowners want ventilation and relatively unobstructed views.
Sliding Windows
Move horizontally rather than vertically. Useful in wider openings and areas where homeowners prefer straightforward operation.
Picture Windows
Fixed windows that don’t open. Commonly used in living rooms and other areas where natural light and outdoor views are priorities.
Bay and Bow Windows
Extend outward from the wall, creating a distinctive architectural feature with additional light. We’ve completed Pella bay window projects in the Pittsburgh area, including a project in Fox Chapel. Learn more about our bay and bow window replacement services.
Specialty Shape Windows
Arched, circular, and other custom-shaped windows for homes with unique architectural details. We can help explore appropriate options for existing specialty openings.
Pella Patio Door Installation in Pittsburgh
In addition to replacement windows, we install Pella patio doors.
If your current patio door is difficult to operate, has worn weatherstripping, or no longer closes properly, replacement may be worth considering.
Pella offers different patio door configurations, including sliding and hinged styles. The right choice depends on the opening, available floor space, exterior access, and the appearance you want.
Sliding patio doors are useful when you don’t want a door swinging into a room or onto a deck. Hinged patio doors may be preferred when homeowners want a more traditional entry style.
During an estimate, we can discuss the available Pella door options and evaluate the existing opening.

Are Pella Windows Energy Efficient?
Energy efficiency is one of the main reasons homeowners consider replacement windows.
Older windows may have deteriorating weatherstripping, gaps around the frames, failed insulated glass seals, or other problems that contribute to drafts and uncomfortable rooms.
Pella offers insulated glass packages and Low-E glass options designed to help manage heat transfer. However, energy performance varies by window series, glass package, frame material, and installation. Not every Pella window has the same efficiency rating.
When comparing replacement windows, homeowners should review the specific product’s NFRC ratings, including U-factor and solar heat gain coefficient. ENERGY STAR certification, where applicable, can also help identify products that meet relevant performance requirements.
For Pittsburgh homeowners, proper installation is especially important. Even a window with excellent energy performance can allow drafts or moisture problems if it isn’t properly installed and sealed.
We’ll help you compare available glass options based on your home and the windows you’re replacing.
Replacing Windows in Older Pittsburgh Homes
Pittsburgh has a wide variety of housing styles, from older brick homes to newer suburban construction.
Replacing windows in an older house may involve conditions that aren’t immediately visible. Window openings can be out of square. Existing frames may have deteriorated, and original interior trim may need to be preserved.
In some homes, homeowners want to maintain the appearance of traditional divided-light windows while upgrading to modern replacement products. These details should be considered before ordering.
Window Installation Specialists has worked with Pittsburgh-area homeowners since 1973, and we understand the importance of selecting windows that fit both the opening and the character of the home.
For properties with historic architectural features, we can discuss available Pella wood windows, grille patterns, and other design options.
Why Professional Pella Window Installation Matters
A properly installed replacement window should open and close smoothly, fit securely, and be appropriately sealed against outdoor conditions.
During installation, attention needs to be given to the condition of the opening, the window’s alignment, fastening, insulation, flashing where applicable, and finishing work. The exact installation method depends on the product and the existing construction.
At Window Installation Specialists, our employee installation crews work with homeowners throughout the replacement process. We also help homeowners understand the differences between window products before making a decision.
Our goal is to provide a professional installation that complements the home and allows the selected windows to perform as intended.
