Improving Home Performance Through Andersen Window Replacement
Older homes in Philadelphia and across southeastern Pennsylvania often deal with drafty frames, failing seals, and windows that no longer perform the way they should. Replacing those windows with properly installed Andersen systems helps restore comfort, improve energy performance, and bring long-term reliability back to the home.
At Five Star Contractors, we install the full Andersen Windows product line across Chester, Delaware, Montgomery, Bucks, and Philadelphia counties, as well as northern Delaware. Every project is approached with a building-science mindset, meaning we look at how air, moisture, and temperature move through the home before recommending a solution.
Convenient Financing Plans Available
Every project is unique, and we want to help you plan for the cost of yours so that you can enjoy the results of your investment without having to worry.
What It Means to Work With an Andersen Certified Contractor
Being an Andersen Certified Contractor is not just a label. It reflects training, verified installation practices, and product-specific knowledge that directly impacts how the windows perform after installation.
Certification requires a working understanding of Andersen’s installation standards and proven customer satisfaction. That matters because Andersen windows are engineered systems. When installed correctly, they perform as designed. When installed poorly, even a high-end window can lose efficiency, develop air leaks, or run into warranty issues.
In practice, this means understanding how each Andersen product line performs in real homes, especially in the older houses common throughout the Philadelphia region. It also means recognizing where problems typically start, such as improper sealing, out-of-square openings, or incorrect flashing details, and addressing those conditions during installation rather than working around them.
Andersen Windows Available Through Five Star Contractors
Andersen Windows produces a wide range of window series designed for different performance levels, styles, and budgets.
The 100 Series uses a Fibrex composite material that balances durability and value.
The 400 Series builds on that with enhanced performance and design flexibility.
The 500 Series adds premium specifications, including high-performance glass options with low-emissivity coatings that reduce heat transfer and improve year-round comfort.
Andersen windows are also rated through NFRC standards, which provide measurable data on U-factor and Solar Heat Gain Coefficient. This allows homeowners to compare performance across different options in a clear, objective way.
We install Andersen windows in a range of styles to match both modern and historic homes:
Casement windows that open outward for strong ventilation and tight seals
Double-hung windows with two operable sashes; common in traditional and older colonial homes
Bay and bow windows that project outward, adding depth and light
Fiberglass windows offer a modern look and dimensional stability across temperature changes
Wood windows with a traditional interior wood finish, ideal for older homes and restoration projects
Picture windows with fixed glass for clear, unobstructed views
Sliding windows for horizontal operation in tighter openings
Andersen Patio Doors and Entry Door Installation
Many homeowners choose to replace windows and doors at the same time to create a more consistent look and improve overall performance across the building.
We install Andersen patio doors and entry door systems alongside window projects, including hinged patio doors and sliding configurations. This approach helps align materials, finishes, and performance details while reducing the need for separate contractors or staggered timelines.
Our patio door installation and entry door services follow the same installation standards used for Andersen window systems, keeping the full exterior system working together as one integrated package.
Andersen Windows for Older Homes in the Philadelphia Area
Many homes in Philadelphia and the surrounding counties were built decades ago, which often means aging wood frames, outdated glass, and window openings that are no longer perfectly uniform. Across Chester County, Delaware County, and Montgomery County, it is also common to see signs of moisture absorption in older framing, fogging between panes, and settling that affects how windows open and close.
These conditions are exactly where Andersen’s product range is especially effective:
Customization for Non-Standard Openings
Andersen windows can be sized and configured to match older, irregular openings, which helps create a proper fit in homes where original framing has shifted over time.
Fibrex Framing
Fibrex composite material resists rot and moisture damage, unlike older wood frames, helping reduce deterioration that can affect long-term performance.
Modern Glass Packages
High-performance glazing helps reduce energy loss often associated with single-pane windows or failing insulated glass units, improving comfort and reducing drafts.
These upgrades are particularly effective in older homes where comfort issues are tied directly to air leakage, weak seals, and reduced thermal separation between indoors and outdoors.
