Customers say: True professional
"I contacted CWE to replace 8 windows and 1 patio door. Jeff came by and did the consultation. He was very friendly and professional. Communication 5/5 - Jeff was very responsive to questions and clearly communicated the work and timeline. Timeliness 5/5 - Both the consultation and installation started on time. The windows actually arrived sooner than expected. Quality 5/5 - The installation team laid down blankets before starting any work. They removed the old windows without damaging the surrounding wall. They installed the new windows and applied the cleanest caulk line I’ve ever seen. They cleaned up after themselves. The Anlin windows that were installed works perfectly and are beautiful."

"They did an excellent job and I highly recommend them for window replacement work. Gary Chern provided a very clear presentation of the company and the windows they offer with various options. Larry Khimich was very communicative with the details of the scope of work and their crew did an excellent job. They damaged one lawn decoration that we discovered later and they provided payment for replacement of the decoration. Mistakes happen and they made good on the damage. They did the work in October and it is now the end of March. No problems and we are very happy with our new windows!"

After some unexpected challenges with the way our home was built, our installation crew quickly and efficiently adapted to make sure our windows and door were installed with expert care.
