Installation plays a critical role in realizing the performance potential of any high-efficiency window. Even a high-end glass unit underperforms without proper anchoring, leveling, and seal integration. Precision installation ensures tight compression, even sash movement, and consistent edge sealing. This minimizes air infiltration and thermal leaks that can occur between frame and wall. Every opening is measured, prepped, and fit with materials that match its unique structure. The result is a window that actively resists outdoor temperature changes while maintaining a stable, quiet, and well-regulated indoor environment.
Unlike standard windows trimmed to approximate sizes, custom energy-efficient units are built around your wall’s exact opening dimensions. This tight fit prevents the formation of air pockets or thermal bridges where energy would typically escape. Combined with multi-step sealing and edge spacers, custom units ensure uniform pressure distribution and reduced heat movement. Tight alignment improves both structural longevity and energy retention by keeping thermal resistance consistent across all edges and corners. It’s not just a better fit—it’s a smarter system that works in sync with your home’s envelope.
Older windows may look fine but often fail where it matters most: energy performance. Single-pane glass, deteriorated seals, or metal spacers all contribute to significant heat loss. Modern energy-efficient windows incorporate insulated chambers, inert gas fills, and low-emissivity surfaces to reduce overall U-factor and enhance solar heat gain control. These updates reduce your reliance on heating and cooling systems and improve indoor air stability. Replacing outdated windows with high-efficiency systems eliminates hidden inefficiencies and restores comfort, all while upgrading the functionality of the home’s exterior envelope.
EXCELLENT Based on 13 reviews kim edmondson2025-07-02Trustindex verifies that the original source of the review is Google. Inland NW Windows did such a tremendous job replacing 5 windows for us that we've called them out to do 2 more! The installers were friendly and did good work, considering the old place they were working on. They were also thoughtful around my landscaping, careful not to damage roses and tulips planted below the windows. I highly recommend them.

Inland window came in and did a really good measurement then after the window company had completed building everything. They came and installed I think it was 11 windows in 2 days. My wife works at home and they were very considerate of that. Great job Inland windows, highly recommended. Elina Schultz2024-10-21Trustindex verifies that the original source of the review is Google. Great service from beginning to the end of work completed. Paul was great at communicating throughout the entire process and was available to answer any questions I had about installing the windows and provided detailed answers. The windows were installed in the timeframe that was discussed and the work crew was respectful, did a great job and cleaned up after themselves. The windows themselves are great and just what I wanted and I am so pleased with them I am thinking about having some more windows done in the future by Paul and his crew. Thank you! Michael Eades2024-10-16Trustindex verifies that the original source of the review is Google. I called Inland to quote me a window installation. They came out in just a couple days for the quote, a couple days after that for the measurement, and told me the windows would arrive in 4-6 weeks. 5 weeks later, three huge windows were installed in my house. They did a great job and were easy to communicate with.
