Why Our Replacement Window Service Is The Best?
100% Customer Satisfaction Guarantee
We aren’t happy unless you’re happy. Following every installation we make sure our customers are thrilled with their new windows, and that the jobsite is properly cleaned-up. We want our customers bragging to their neighbors about us!
We Offer Factory Direct Pricing
What does factory direct pricing mean to you? It means we cut out the middle man 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. Each job we have windows custom ordered to ensure they fit your home. All this service and competitive prices? 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… “LowE glass with the argon gas!”
We Are Family Owned and Operated
The Window Source of Raleigh is a family owned business. From the consultation to the installation, we do it all!
