What is your warranty? Product warranties?
Penn Windows & Doors gives all customers a free 10 year service and workmanship warranty with any installation. This warranty “click here for full warranty details” works in conjunction with the manufacturer’s warranty and covers the labor for all covered warranty work and parts 10 years after installation. It also covers our workmanship – meaning the quality of our installers’ work – giving you peace of mind that your job is correctly installed, sealed, leveled, and solid. Caulk has a 1 year warranty. Any warranty work or questions – simply call the office at 610-433-4196 or email the owner directly at erin@pennwindows.com.
After the 10 year period, we’ll still service your windows and doors! There’s a service/trip fee charged. Just ask when scheduling your appointment for the current rate. Be aware – manufacturers cover most parts for the lifetime of your home, but they do NOT cover shipping. Shipping charges could apply at any point and are passed on to the customer without markup.
