About Our Company – Why We’re the Best!
We aren’t happy unless you’re happy — that’s why we offer a 100% customer satisfaction guarantee!
Following every installation, our family-owned and operated business wants to make sure our customers are thrilled with their new windows and that the jobsite is pristine. We want our customers bragging to their neighbors about us! If you’re in Raleigh, Durham, Cary, Chapel Hill, Burlington, or surrounding areas, give us a call for an in-home consultation at your convenience.
We Offer Factory Direct Pricing
What does factory direct pricing mean to you? It means we cut out the intermediary to save you money. Why deal with paying more from big box stores when we bring the windows to you right off the production line. For each job, we have windows double measured and custom ordered to ensure they fit your home to a tee.
All these services and competitive prices too? That’s what factory direct means to you.
Our Replacement Windows Are 100% Green & Energy Efficient
Almost all of our windows are Energy Star® compliant. Low-emissive (Low-E) glass is window glass that has been treated with an invisible coating. Windows treated with Low-E coatings are proven to reduce energy consumption, decrease fading of fabrics, such as window treatments, and increase overall comfort in your home. Repeat after me… “Low-E glass with the argon gas!”

Our business philosophy is simple — we do our best in how we treat people and how we conduct business.
This means:
- Keeping our promises by doing simple things like returning calls and arriving on time for appointments.
- Our sales approach is meant to keep you, the consumer, in charge and provide you with the freedom to make informed, sensible decisions without feeling compelled to buy.
- After the sale, we will complete an organized installation process that will allow you to use your new products for many years to come.
- Every client receives the same level of service that we demand for our own friends and family.
