Reviews
Karen - Joliet, IL
“We had a great experience with Welsh Windows. We had quotes from several different companies and Welsh was the most competitively priced while still being affordable. The communication was great throughout the whole process and our windows came in when they said they would. Rob and Ron were the dynamic duo on our installation day(s). They worked so incredibly hard not even stopping for lunch. They went above and beyond to ensure we were happy with the end result and they left zero mess. We will use Welsh for future window/roofing/siding needs and definitely recommend them to everyone. Thanks Welsh Windows!"

"We loved our experience with Welsh Windows, whole process was wonderful from beginning to end. Communication was great from our first phone call until the installation. The guys were prompt, very neat and our new dining room window looks amazing. Thanks Welsh Windows for getting our job done seamlessly!!"

“So Welsh’s Ron & Ronnie just got done putting in our new Cherry Hill (dark red Fred) door. They were so fast and efficient and cleaned up after themselves. They truly know what they are doing !!! They even vacuumed the floor where a portable closet had to be moved for the side lights which hasn’t been moved in quite some time…..And the door is gorgeous; put in impeccably!!!”
