Reviews
Ihab - Oak Lawn, IL
“Welsh Windows Plus was referred to us by our neighbors, and we are beyond happy with the job that was done! From the quality of the windows to the service and professionalism of the installers, the entire experience from sale to completion was a wonderful one. We will definitely be in touch with them to do other home projects, and would not hesitate to recommend to anyone that there is no other phone call to make if they are in the market for any of the services that Welsh offers!!!!!"

"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. Anyone that accepts quick pay is such a convenience for me! I definitely 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!"

“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.”
