Recently we replaced all the windows of our home. Choosing Precious Window to install our new windows was the best decision! From start to finish, the experience was seamless and professional. Jeannie was incredibly knowledgeable and patient, guiding us through the different window options without any pressure. She helped us find the perfect style and energy-efficient features to match our home and budget. The installation team led by Andy was outstanding! They were punctual, respectful of our property, and meticulous in their work. The cleanup afterward was impeccable. The windows themselves are stunning! We've already noticed a significant difference in noise reduction and temperature control. We are beyond thrilled with our new windows and the exceptional service provided by Precious Window and Jeannie. Her commitment to quality and customer satisfaction is truly commendable. We highly recommend them to anyone looking for window replacement.

The installations were all well done and comprehensive. The installers kept us well informed at all stages. There was just one small hiccup, and it is being resolved at this time. They don't have a big crew so we had to be a bit flexible on scheduling, but they do show up when they say they will and work hard the whole time. We will definitely recommend them.

I had the pleasure of working with Precious Window not once, but twice, to replace all the windows in my apartment and both experiences were outstanding. The first project was back in 2020 when they installed Series 5500 Aluminum Heavy Duty Double Hung windows in my home. The quality of the windows and the meticulous installation process left a lasting impression on me. Fast forward five years, and I needed to transfer the warranty. To my surprise and delight, Jeannie Lai from Precious Window remembered me immediately. This level of personal attention and recall after such a long period speaks volumes about their dedication to customer service.

I ordered new aluminum windows and glass sliding doors to replace my 30+ year-old ones. Unfortunately, the new windows arrived with scratched aluminum frames and overhanging gaskets, indicating a lack of quality control.

Additionally, a technician was scheduled to replace the rubber gaskets but never showed up, and I was unable to reach anyone at the office during business hours.

Based on my experience, I would recommend exploring other window providers.

我去年2月份在贵厂订购了4个Casement的窗子，安装上后，使用到现在近一年，非常满意你们的产品，与美国其他大牌厂家相比，贵厂的产品性价比特别高。这个月又下了玻璃拉门和门二边的玻璃门框的订单。特别值得一提的是贵公司门市部的Max Kang先生，他不但专业精通，服务态度非常好，很有耐心。特别是我这样不是专业安装窗子的房屋户主，他不厌其烦地解答我的问题。在我预定玻璃拉门时，尽管我在图纸上，已经标明了把手的位置，但他还是不怕麻烦地走出来，带我到拉门展示处，实地与我确定，我所要的把手位置，让我完全放心地回家。我已经多次在几个500人的房屋修理微信群里，介绍贵厂的产品和服务。希望贵厂产品越做越好，生意蒸蒸日上！

I purchased several windows with low e and argon glass to replace 35 year old windows. These windows are performing worse than the old ones. They came out to check on my complaint and their technician admitted that something was wrong. After several attempts to contact them after their inspection, I was now told that the technician never said there was anything wrong and their windows were not defective. I filed a claim with BBB but Crystal refused to stand by their product. I am very disappointed with their customer service.

There seem no quality control on their windows. Install 20+ windows 10 years ago but started to have issue after 5 years. Some windows started to leak air and became very fogy inside. Warranty only cover replacement glass. You have to either take the window to the factory or pay a premium labor fee for worker to come to the house. I'm pretty handy so i ordered the replacement glass (took a month) and re-installed all by myself. It took some labor and silicon for replacing the glass. So far i have replaced almost 10 problem windows. However, today when i was replacing the last one, i realized that the original glass was actually a broken one. the glass has broken corner and the missing piece leaves a hole. You can tell that the missing piece happened before they did the sealing as the seal rubber covers the broken edge. it was such obvious defective part but it was still put into production. it tells people that nobody cares the product quality at least at factory. also both the original and replacement glass are bit small to the window frame. Good news is it was surprisingly easy for me to take the original glass off the window. but bad news is this is because there is no silicon glue and seal the glass to the frame. I have totally lost confidence to this product and wondering if the replacement will have the same foggy problem years later as they don't look like quality ones either.

I have been trying to get 2 replacement sashes for a customer since the beginning of September. The first excuse was that the rep did not see the credit card authorization form sent to his email. After that it was a problem with some of their equipment at the shop. Now I have been waiting for delivery since the beginning of November.
If you are looking for replacement parts for crystal windows, save yourself the hassle and do a full replacement from a different manufacturer.
My customer is livid, and so am I.

Edit: The Crystal rep delivered the sashes and returned the CC payment to my customer. While the overall experience was not great and took longer than expected, Crystal did finally end up delivering the sashes, and they did fit into the frame with the measurements I provided and matched the existing windows.
