Energy Efficiency

Green Built Window is more than just a name. Together, with our parent company, Green Built Northwest, we can offer more than just improved energy efficiency through windows. We offer full weatherization services for your home, including energy audits, insulation, duct sealing and other energy saving services for your home or multi-family building.

Many Seattle homeowners interested in saving energy also add insulation to their attic and basement, and do air sealing to increase the energy-efficiency of their home. New insulation helps make your home more efficient by better retaining the desired temperature of enclosed spaces. When used in conjunction with new windows, new insulation will help you save even more on utility costs, conserves non-renewable fuel sources and provides greater comfort throughout your home.

More than just return on investment

If your windows are more than 15 years old, you may be putting up with draftiness, windows that stick in their frames, and skyrocketing energy bills. Energy-efficient windows would be a great improvement, but replacement can be very expensive.

All-new vinyl windows for an average 2,450-square-foot house run about $15,000, according to the “Remodeling Impact Report” from the NATIONAL ASSOCIATION OF REALTORS®.

But that doesn’t mean the numbers can’t make sense for you. For starters, window replacement is one of the best home remodeling projects in terms of investment return: For average-quality vinyl windows, you can recoup 80% of the project cost in added home value, according to the “Remodeling Impact Report.”

Based on the vinyl window replacement projects in the “Report,” that’s a value add of about $12,000 if you should decide to sell your house. Note that federal tax credits that were previously in place for energy-efficient window replacements have expired.

Will you love your new windows? Very likely — homeowners responding to the “2015 Remodeling Impact Report” gave their window replacement project a Joy Score of 9.4 — a rating based on those who said they were happy or satisfied with their remodeling, with 10 being the highest rating and 1 the lowest.

Great Company from start to finish! Beautiful work and very communicative. Fabian and his team are wonderful!
