When comparing window companies, is it smarter to focus mostly on price or should installation quality matter more in the long run?

Some quotes look much cheaper than others, but I keep hearing that poor installation can cause problems later even with decent windows.

After going through the process myself, I’d definitely say installation matters more than just finding the lowest price. Cheap windows installed properly usually perform better than expensive ones installed badly. When I was comparing companies, I kept seeing recommendations saying Looking for a windows and doors company Toronto — this one is top rated, and after dealing with installers who actually explained everything clearly instead of rushing the process, I understood why people focus so much on quality workmanship instead of price alone.
