"I am very pleased with the communication of this company. I reached out to them at a job site and met Leaha's their project manager. The properly got me setup for an estimate of services. I did decide to replace 4 front windows. Deposit was easy to make. Windows came in timely. Yesterday my project manager was also Leah who came first advised me what was going to happen, whom was coming and when. My window team came, two great guys that amazed me how quick they got my windows out. They were upmost polite and respectful of my home and myself. Very little dust and they cleaned up everything. My windows were put in 1982 and I had cracks and they were unsafe. This team worked wonders.....new easy to be clean tilt in windows ...even easy for a woman to move. The window guys the caulking is the best Ive ever seen....so sealed and straight. The went over how to remove screens, clean windows. Kudos to the entire team. Project Manager Leaha drove back...spoke with me, inspected"

"Glass Impressions did a wonderful job of cleaning all 19 windows in our home, inside & out, including the inside sills, screens and also 2 glass storm doors. Mr. Waters and his team are very good at what they do. They were very reasonable. I plan to use them again, as needed."

"I contacted Portillo because there was a leak above my second story window due to missing mortar and missing/deteriorating sealant around my windows. The entire process was very smooth. He came out to do an estimate and then came back two days later and completed the work quickly. Great communication and quality of work. Will definitely hire again."

"I've dealt with Garrety Glass a few times. They get the job done. The quality of work is good but they can take a long time and have mixed up a few order of mine. Once it was with scheduling. Another time, they ordered a tempered glass when I just needed regular window glass cut to fit and installed. Another time, they sent the wrong quote. Bottom line: the workmanship is quality. Unfortunately, they will probably waste your time or money."
