Windorco has been installing windows throughout the greater Northwest for over 54 years. We have always trained our own installers, never using sub-contractors or paying piece work, which can lead to shoddy workmanship and rushed installations. We believe spending more time and training on installations is essential. This keeps our clients pleased, and increases our business with referrals and repeat customers. We have an excellent record with minimal service calls, and strive to keep it this way. All materials used are of exceptional quality. Paintable, high performance caulking is used on both interior and exterior applications. We use Fir and Hemlock wood trim, never MDF or finger jointed stock. Installers utilize tarps and usually switch one or two windows out at a time, making the experience as comfortable as possible. Your new windows are washed both inside and out, and debris is removed when the job is finished. Stop by our Ballard showroom, open Monday through Friday 8-5, and browse through pictures of some of our completed installations.
