The Keystone Method
Giving you superior service each step of the way.
We stake our name on quality workmanship and old-fashioned attention to detail, helping you find the perfect fit for your home. Our step-by-step method for installing your window or door is outlined below – from scheduling a free estimate to the installation itself.
Remember, not all types of windows are going to be appropriate for your home. We recommend meeting with a window specialist instead of a contractor, to be sure you’re installing a window that fits your home – not making your home fit the window.
1. Call, e-mail or visit. Contact Keystone to schedule your consultation. We will ask you a few basic questions about your upcoming project, schedule an appointment at your convenience, and e-mail helpful information to get you started, including client testimonials and references.
2. Meet with a top window specialist. One of Keystone’s consultants will visit your home to meet with those involved in the project, presenting design ideas and discussing window and door styles. He or she will inspect your current windows or doors, share details of Keystone’s guaranteed products, and follow up with a comprehensive cost proposal.
3. Take the time to consider your window and door options. Choosing the perfect fit for your home can be a big decision. We realize you have hundreds of options to consider and styles to choose from. After your in-home consultation, Keystone will provide you with a detailed proposal, and we’ll be standing by to begin installation at your convenience.
4. Think about your financing options. Keystone offers financing through Salal Credit Union. Speak with one of our consultants to learn more about your financing options.
5. Schedule your installation date. Call your window specialist to schedule your installation date. Keystone windows and doors are installed by our craftsmen who guarantee their work will be perfect. After all, the best product is only as good as the installation itself. We also offer a lifetime warranty on our installation and labor, giving you total peace of mind and a beautiful final product.
6. Give us your feedback. Visit the Keystone website to upload your comments and/or photos from your project. As always, we’re available to answer any questions and address any concerns at 206-860-8686.
