Hear From Past Clients

"We had all of our windows replaced by Brennan Enterprises. The experience with this company was great throughout the whole process. We would definitely call them again and have already recommended them to others and will continue to do so."

Tom & Cathy

"Great experience! I got a large bay window and two side windows replaced to new double pane windows. Scott was my contact, very helpful, not pushy, fair price... Very nice and professional. I definitely would recommend. Seems like a well run family business."

Fred

"Brennan Enterprises came highly recommended from a family friend who was wonderful from the first phone call to consultation. They gave my childhood home a face-lift right away and they’re so easy to open & close!"

Cindy

"Pleasant and friendly people. Quality product and quality work. They make sure everything is done correctly... I really appreciate the Brennan Crew!"

Lauren

"Brennan was the right choice for our custom window job. Communication from the office and the field staff was timely and accurate. Each trade that was part of the job was efficient and did excellent work. Job site kept clean throughout. Would not hesitate to use Brennan in the future."

M Shelton

"I'm so glad that I chose Brennan to replace my house's 25-year-old windows. I chose Andersen 100 Series Windows because they come with 2 warranties. Brennan's prices were half of Renewal by Andersen's! Brennan's employees are the best. Kudos to Dustin (my Sales Rep), Jake (my installer), and Sheryl (payments)."

Howard

"We love love love our new picture windows! Kerry Brennan himself came out and went over everything with me!! It took a few weeks to get them but the installation was quick and easy. Will definitely use them again!"
