  • What are the main differences between vinyl window products?

    There are many vinyl window manufacturers in the market and some very good products. Once you have established that you are interested in a vinyl window replacement (vs. fiberglass, wood-clad or other), then you will want to consider the following:

    • Installation method and protection for your home
    • Glass strength and energy efficiency
    • Quality of components and features such as insulation or argon gas
    • Frame design, color, fit with your house decor.
    • Inside trims
    • Safety and Locking features
    • Warranty and service policies of your installer
    • Pricing

  • What is a Critical Measure?

    The first step in replacing your windows is our comprehensive Critical Measure. After you have decided on your style and features, our fully trained craftsmen focus on the accuracy in each window measurement to ensure a quality window replacement. Only then are your windows ordered. The quality of the installation itself is just as important as the quality of the window for optimal functionality.

  • Do you use any subcontractors for window installation or warranty work?

    We do not use subcontractors to install or repair windows. Your windows will be professionally installed by Washington Energy Services factory trained and lead certified employees. In addition, all of our installers are licensed, bonded and drug tested.
