"I needed a front door leaded-glass window repaired. I got a quote from another company for over DOUBLE what Raul quoted, and with a 4 week turnaround (Raul quoted 10 days and successfully completed the job in that time). He was timely, responsive, and did excellent work. He even added a new crossbar as well as a new border which wasn't included in the original quote. He did so at no extra cost, but I chose to pay him because I very much appreciated both that gesture and his honest approach. I was very pleased all around."

"We could not be happier with our new bathroom, thanks to McCormick! Khaled was knowledgeable and really took the time to understand our style preferences. The whole team was great about keeping the workspace tidy, which we appreciated. Now, we have a bathroom that feels luxurious and welcoming. Highly satisfied with their work!"

"They did a great job. We were really impressed with how responsive they were - they came and gave us an estimate while the shower was still being built and installed the glass as soon as it was possible to do so - so there was no delay at all. Very happy with the end result."

"I took a cold call from Chris in Fall 2018 and am so glad I did! I had been looking for replacement windows for original 1930s wood windows, as well as a few 1970s aluminum windows. For me, vinyl just wasn't going to work as I wanted to keep the quality of the house in its original form, as well as upgrade the 70s remodel to be more consistent the original part of the house. Chris came and suggested a new product for him, Sierra Pacific. I did some research and determined, for my project and for the cost (I had bids as high as $100K for this job) that I was willing to give this product and Chris a shot. It was a very large job, 27 windows, some on the second story, plus a large 8ft glass slider, and a standard exterior door. The project did take several weeks, but Chris throughout all of the questions and decisions was helpful, knowledgeable, and aimed to please. Installation was smooth and he takes pride in making sure things are done right, are working properly, and that I was happy with the product and the work. Chris is wonderful to work with – we have had the windows in now for about 6 months and are extremely happy with the product. The quality is superior to your standard vinyl install, we sound proofed one side of the house due to neighbor noise (it works like a charm), and it is wonderful to have a fully functioning house of beautiful windows - that are consistent from original house to addition. I would highly recommend Chris and Sierra Pacific if you are considering a replacement for wood. Thank you Chris for all the work, for your partnership and guidance!"
