AG Window Services

AG Window Services handles window and door replacements from their base in Garland, Texas. They install energy-efficient windows, patio and sliding doors, commercial units, egress windows, and custom options across the Dallas area. JP and Ana oversee the day-to-day work, from initial measurements through final install. The company provides free estimates and focuses on straightforward replacement jobs that customers describe as quick and direct.

Homeowners report full-house window swaps that make rooms brighter and improve insulation on older properties. JP and his crew finished a 36-window project in a day and a half while keeping the site clean. Other jobs involved swapping out twenty-year-old windows, sealing everything properly, and leaving both inside and outside areas spotless. Reviewers named JP, Ana, and the installers for staying on schedule, answering questions during the work, and handling details like trim without extra mess.

The crew arrives on time, communicates clearly about options and timelines, and sticks to the quoted price. Most jobs wrap in one or two days with thorough cleanup afterward. They work on both residential and commercial sites, adjust schedules around the customer, and return calls promptly. Pricing stays consistent from the first visit through completion, and the team covers the Dallas region with the same approach on every project.
