Now that we’ve introduced both brands, let’s do a detailed comparison.
Cost Comparison
One of the biggest factors for most homeowners is cost. Window Mart is known for affordability, while Pella commands a premium price.
For basic vinyl windows, Window Mart’s prices start around $200 per window installed. They have frequent sales that can bring that price down to $150 or lower.
Pella’s vinyl windows start around $350 installed and go up from there. Their top-tier wood windows can cost $1,000 or more per window.
Of course, cost varies based on the size, type, and features of each window. But overall, Window Mart offers greater value and budget-friendliness over Pella.
Materials and Construction
Windows are a complex system of frames, sashes, glass, and hardware. The materials and engineering quality make a big impact on performance, durability, and aesthetics.
Window Mart primarily sells vinyl windows, which are cost-effective and low-maintenance. However, vinyl quality varies among their manufacturing partners.
Some Window Mart vinyl windows use welded frames and multi-chamber construction for rigidity and insulation. But lower-end models may be thin and prone to warping.
By comparison, Pella uses premium vinyl formulations with thick walls, fusion-welded corners, and insulating foam fill. Even their basic Impervia line beats standard vinyl windows on strength and durability.
For wood windows, Window Mart relies on suppliers like Simonton and Atrium. The wood is usually lesser grades of pine or poplar. Compared to Pella’s kiln-dried oak, mahogany, and other fine woods, the construction is not as robust.
Pella takes the crown for superior materials and construction. Their industry-leading innovation and rigorous testing result in extremely durable, high-performing windows.
Energy Efficiency

Energy efficient windows save money on utilities and make homes more comfortable.
Efficiency is measured by the U-factor and Solar Heat Gain Coefficient (SHGC).
The lower these numbers, the better.
For reference, Energy Star recommends U-factors of 0.27 to 0.32 and SHGC around 0.25 to 0.40 for the most efficient windows.
Window Mart’s vinyl models can match the Energy Star guidelines with double or triple pane glass, argon gas, and low-E coatings. With these upgrades, their windows reach U-factors of 0.27 to 0.30 and SHGC of 0.25 to 0.28.
Pella goes beyond the minimum standards with triple pane glass and two low-E coatings standard. Their optimized foam spacers and thermally improved frame deliver U-factors as low as 0.17. SHGC can get down to 0.19.
Pella outperforms Window Mart to provide maximum energy savings and comfort. Their advanced materials and engineering allow for superior thermal performance.
Styles and Customization
When it comes to options, both Window Mart and Pella deliver:
Window Mart
- Dozens of vinyl, wood, and fiberglass models
- Single hung, double hung, sliding, casement, awning, and specialty shapes
- Custom sizing in 1/8” increments
- Interior and exterior color choices
- Add-ons like grids, hardware finishes, and glass tinting
Pella
- Impervia, Lifestyle, Architect, and Designer vinyl lines
- Single hung, double hung, casement, awning, and sliding
- Dimensional adjustability and custom shapes
- Exterior color matched to trim
- Divided light grids, hardware, and interior wood species
Window Mart works with multiple manufacturers, so styles and options vary. Pella maintains consistency across their own lines, but the total customization is more limited.
For exotic wood grains and unlimited interior/exterior color matching, Window Mart pulls ahead. For seamless design within their vinyl families, Pella is unmatched.
Warranties
The warranty coverage reflects the quality and expected lifespan of the windows.
Window Mart’s warranties differ depending on the manufacturer:
- Glass coverage: 10-20 years
- Vinyl and hardware parts: 5-10 years
- Labor: 1-5 years
Pella warranties are straightforward:

- Glass: 20 years+
- Materials and workmanship: 10 years
- Labor: 2 years
Pella also offers several transferable lifetime warranties on glass, vinyl, and other components.
Pella provides better assurance against defects and gives peace of mind for long-term ownership.
Their lifetime warranties are hard to beat.
Professional Installation
Proper installation is crucial for windows to operate smoothly and prevent leaks.
Window Mart contracts experienced independent installers for each job. They have high standards for their installers, but quality can still be hit-or-miss. Getting someone reliable is not guaranteed.
Pella takes installation into their own hands. Their factory-trained professionals follow stringent protocols and undergo continuing education. This gives Pella unmatched control and accountability for the entire customer experience.
Between large retailers, local crews will likely offer greater attention to detail. Pella’s dedicated installation gives them an advantage on seamless integration and water tightness.
