When we pulled into the very small parking lot on Northern Boulevard, we almost kept going - it was…read morea tiny storefront - not the huge showroom we expected. We are SO grateful we stopped! While the showroom is small, the person was so helpful - friendly, not pushy. We left with so much information - and after mulling it over, we called to have a salesperson come over, look at what we needed done and give us a quote The salesperson, Chris, came when he said he would, looked the job over, asked what we wanted, and gave us a quote. We had waited so long to have the windows replaced (years!) that we decided to 'go for it''. Chris said we'd have a Project Manager that would stop by and check on the job (which would take 2 days) - it sounded too good to be true. The installer, Chris (different Chris!) came by, to take the final measurements and our windows were ordered. We were told it would take 4 - 6 weeks. Within that time frame, we were called and given the install date. On the date given, a truck pulled up, dropped off everything needed to do the job - and about an hour later, Chris and his assistant got to work. Later that day, our Project Manager showed up, just to make sure everything was progressing nicely - yes, we really did have a Project Manager! The next day while Chris and his assistant finished the job, Chris the salesperson showed up just to see how things were going - I don't ever recall seeing a salesperson after a sale was made! Towards the end of the second day, our Project Manager came by and checked out the whole job! He was satisfied - and we were thrilled. Replacing windows is not cheap, and it's something easily put off, but I'm writing this in my warmer, quieter living room because we finally made a choice - and we are so glad that we chose WindowRama!

They are always responsive, knowledgeable and courteous to say the least. Crystal Windows has always had my back when I needed warranty calls to be done. They are on time and professional. The after service Ryan Lin is the best with following up and keeping customers updated. It's always a treat to walk thru Crystal and seeing the owners Thomas & Steve working hand & hand with their staff as if this was a mom and pop operation (I believe they are a nation wide operations with multiple factories according to the pictures on the walls). It is rare to see a family owned and operated factory of this size & magnitude in the United States in todays business climate. Keep up the good fight Crystal Windows!!!

I had explained what's going no with my door lock, including pictures and I was told that they no longer have this kind of lock on hand so they gonna need it to order from China. I was ok with that even tho it wasn't cheep( $$$$$$200). Got my receipt and had been told 2 weeks. After a month of waiting I decided to email them trying to find out the status of my lock. Got nothing. After that I had tried to called them and person on the other side couldn't speak any English. Next business day me and my wife went there together and told them if they r not going to fix our lock we r going to sue. (By the way this place gave us such a run around, no English or I will call back or boss is not here) . Within 2 weeks their track arrived without any replace parts but two man who were no shy about smoking cigarettes in my beautiful home. One of took the lock apart and told me that I need a new cylinder/Lock but not the door handle. Door handle!!!???? What door handle????!!!! I had ordered a lock and this is the receipt. More run around. After they had left I called the office and guess what? No one speaks English till Monday. It's been 4 months now and I am very much ready to sue this place. One last phone call and it will do it. Last time I spoke with them, they had found it "the last one" in the wear house and then fixed my door. 4 moths of lies! 4 moths of wasted time! 4 moths or aggravation and rum around. No any sort of refund since in their opinion I have paid for door handle and not just a part of it that could cost more then $30. Do yourself a favor, save some nerves and buy somewhere else!!!!

Update: got notice that "someone" commented on my review which says opposite , I wish there is a…read moreplace on yelp I can post the photos of those defect cabinets, and I wish I had recorded the conversation I had with the dnc sales person so you know who is lying. They are dishonest person, both online and offline. I went with my gc on august 3rd and ordered cabinets and two vanities, the cabinets arrived on august 16. On august 17, they told me one of the vanity is out of stock and if I still want it I have to wait for one month. I was like "what are you doing in the last two weeks? Why don't you tell me earlier? Now I have to shop for a vanity which is in need in two days." But they just said they do not have it now. It gets worse. When my gc opened the cabinets on august 18 and tried to install them , he found that's not what we ordered. We want two 27" base cabinets but they sent one 30" and one 24". I called dnc directly, of course they said they told me about the change before, but they did not! Then we found the cabinets are poorly painted and has cracks here and there, also the cabinets have different heights, so my gc has to cut them equal in my apt. I argued with dnc, they again denied everything and refuse to do anything to compensate. I am so tired of dealing with them, they are horrible, both the cabinets and the people who work there. Stay as far as you can from dnc.

Unquestionably the WORST experience I have ever had with a business!…read more I am left with damaged floors, and a completely uneven kitchen island due to this company's lack of professionalism, attention to detail, and poor craftsmanship. As part of a recent renovation, my wife and I purchased quartz countertops and backsplash from DNC. We used DNC because they supplied the Kitchen & Bath shop - owned by a woman named Nicole - who we ordered our kitchen cabinetry from. The problems began when DNC sent someone to take measurements. He spoke very little English. He also measured by hand (as opposed to lasers & computer like others will do) and provided no template, as is customary. Two weeks later the installers came, and again there was some language barrier. It became clear that mistakes were made on SEVERAL of the measurements (ie. a 54 inch piece was supposed to be 45 inches, the island was .5 inches too wide). To fix it, they cut the stone in my apartment, which took a long time and filled my apartment with dust - which is highly toxic (look it up). Stone of this nature is supposed to be cut with a water saw, but DNC takes no such precautions. . Due to the errors and cutting required, the installation took several hours longer than scheduled. Zita, the proprietor complained to Nicole - my contact at the kitchen and bath shop to complain about how long the job was taking. I felt very pressured, though the delays were due to their own errors. When everything was done, they asked me to inspect so they could leave. My apartment was COVERED in dust, and the countertops looked very unclean due to silicone spots that were still on the surface. Despite feeling pressured to let them go, I asked them to try to do a better job cleaning, while I looked over the work. I also called my general contractor to come inspect. He took a quick look and thought it looked ok. So I paid them in full, and let them leave. I spent over 4 hours that night and the following morning trying to clean the countertops and dust that had settled into every corner of my apartment. Because of all of the dust on the floor, I had to remove the protective paper that my general contractor laid down after the floors were installed. Upon removing the paper in the kitchen, I saw about a dozen dents in the floor - right where they were cutting! The installers cut the stone over my brand new floors - without ANY protection. Zita denied everything, said I had no proof, and that I shouldn't have let them leave if they damaged the floor. I told her that I didn't see the damage because of the paper covering the floors, but that did not excuse the fact that they made no effort to protect my floors. They could have easily used the melamine slabs in my apt from the renovation. A professional company should not need to be told this. It gets worse! Later that week, I realized the countertop over the island was crooked. The overhang on the left of the island was the agreed upon 1.5". The right side however was only .5". How did this happen? They incorrectly cut the stone to fit around a beam in the island. They cut for a 22" beam instead of 21". Rather than admitting their mistake they just pushed the stone an extra inch to the beam, reducing the overhang on the right side of the island by 1". DNC again denied everything. Zita refused to speak to me... and hangs up on me, saying I am not her customer and (though I paid her directly) and that I should take it up with Nicole. I told her Nicole did not measure or install the stone, and that either way Zita had to make this right for me, or Nicole. Nicole also got nowhere. Despite all of the damage and mistakes and despite photo proof, Zita is unwilling to take any responsibility. Because I didn't notice the damage before they left and because she was paid, Zita believes she is free and clear. What a horrible battle this has been. There are so many honest and professional companies out there who are deserving of your business. I recommend that you stay FAR away from DNC.
