We’ve recently leaned on Windorco for a few window jobs, including glass replacement, window hardware repair, and the production/install of new windows. Based on our experience, I can recommend Windorco without reservation. Class act! When Jeff initially came by to survey our situation, he thoughtfully presented the options, and pointed us toward the most cost-effective choices. When we decided we wanted new windows in our dining room, he accommodated us – during the holidays no less, on a very tight production schedule. The new windows look fantastic! We’ve got a 1924 bungalow, and the windows only reinforce our dining room’s “old world charm.” Great follow through, and the pricing was totally reasonable.
We have 4 large windows that just needed to have the glass replaced. I had contacted numerous other companies that were not willing to replace the glass. Lucky for me, I found Windorco. Jeff came out, measured and was able to confirm they could indeed replace the glass. They did a great job! We are very pleased and will contact Windorco again when needed. Thank you.
We have an old home on Queen Anne. We needed the picture windows replaced in our living and dining rooms. Inside we have the original mahogany window casing that we want to retain. We had trouble finding a company that do the job. Someone recommended Windorco. They were very responsive, completed the job on our tight time frame. The installation was challenging but they executed it perfectly. All done at a very fair price. I would certainly use them again and recommend to anyone.
We LOVE Windorco Supply Inc. We’ve used them 2x, first for a total window replacement in our “new to us” 1922 home. Our huge bay windows came out beautifully, as did the rest of the windows. We just had them back out to update 2 windows that we wanted a new design on. Windorco is thorough with excellent customer service and very competitive pricing. We originally had 3 bids, all within $2-3k of each other and Windorco was the clear winner. Their no pressure, no upsell and detailed process was just what we were looking for.
The team at Windorco came through again. They have retrofitted windows on three homes - two with brick exteriors and the latest one with aluminum siding. The windows were upgraded from single pane aluminum to vinyl thermos. The windows don’t just look great but they add a whole new dimension to the house. The installers finish work is impeccable, clean and careful, and great customer service. Thanks Windorco!
