We recently replaced all of our second floor windows of our townhome with Kim & team. From the first phone call to the... final sign off, we experienced nothing but professionalism. They were available to answer all of our questions and help us decide what windows were right from us. After getting multiple quotes from other businesses, we felt that we were getting the best value and happy we made the right choice. Later this year we plan on replacing all of the first floor windows and will definitely be using Window Source of Raleigh.read more

This was an excellent service from start to finish. David showed me a sample of what I was purchasing and clearly... explained the entire process. There was NO pressure with some special deal only good for that moment. I sat through three of those, so David's approach was refreshing and exuded honesty and integrity. Tyasia did a great job with scheduling and keeping me informed. James was the consummate professional. The installation was smooth with minimum disruption. It was a pleasure to talk with Kim, who provided the many details I wanted about the product. I would HIGHLY recommend this business with no hesitation.read more

Great company to work with. Kim is awesome. Very responsive and communicative. She managed the entire window... replacement project from start to end. Their technician who installed the windows was probably the hardest working person I have ever met. He was quiet, courteous and very neat and clean.read more

I discovered late in renovating a house that I was going to sell that all of the windows needed to be replaced. I... called a couple of companies that said it would be 10-12 weeks to deliver new windows but I had to get them as quickly as possible. I found Window Source of Raleigh online and was nervous about trying someone new, but they have been wonderful to work with: very responsive and delivered the windows on the date they promised.read more

Kim's so responsive and easy to work with. Not only do my new windows look great, Kim made sure to involve the... manufacturer of my home's walls so that these newly-installed windows would not void my warranty. Grateful for Window Source's care!read more

The Window Source of Raleigh is my firm's #1 choice for our flip houses and for client referrals. The work has... consistently been outstanding on numerous jobs they've completed and the customer service is top notch. Kim personally assures every project is handled professionally and with attention to detail. Window Source's prices are reasonable and they have a product for every budget. From start to finish, the greatest of care is given to disrupting the homeowner as little as possible and construction debris is always dealt with fastidiously. If you want quality work at a fair price just call Kim!read more
