Reviews

Ihab - Chicagoland, IL

“​Love the service I received. They were the only ones that came out to look at my one window project where others didn't think it was worth their time. Nothing too big or too small is my kind of business! my window looks perfect and the order and install process was so easy. Also love their payment options. I recommend Welsh for your windows! Can't wait to update some more windows and see about my doors :) thank you Jennifer and Bobby you were great to deal with!"

Phillip - Tinley Park, IL

"So happy with the work done by Welsh Windows Plus. We have had them do window work for us on 2 occasions and could not be more impressed. Excellent work and very professional. We fully intend to work with them in the future on additional projects like roofing and siding."

Melissa - Chicagoland, IL

“Called for an estimate and they were out the next morning. Windows installed that day. Will recommened to anyone that is looking to call them. Bobby made sure to let us know what was needed and they cleaned up once they were done.”
