I love my Royal Tech windows. However; they were purchased many years ago. Recently I called to get an estimate on a house that was inherited. The gentleman showed, measured & let me know the owner who I knew personally, was ready to retire. He never got back with me. So I'd question hiring them. read more

Had our whole house done by them after a fire in 09. Now (2025), have a broken window that has blinds inside. Contacted them in the spring about fixing the window. was told they are closing later in the year. They came and gave me an estimate, but never honored it. I'm still waiting on window and it's now October. They keep saying they're waiting on glass. Have heard nothing from them unless I personally go to their business, then just get excuses from a guy named Joe. Horrible customer service. read more

Royal tech windows is a royal mess!!!!!!!!!!!!!!!!!! PLEASE PLEASE PLEASE REFUND OUR MONEY. NO CALL BACKS, 6 TO 8 WEEKS HAS TURNED INTO 5 MONTHS. Unprofessional owner and staff, girl that answered phone claimed she didn't know how to look up my order, no one comes to work to make the windows etc etc one excuse after another. Refusing to refund and refusing to produce 1 window. Only 1 is what I was looking to replace. Terrible business practices and no respect for paying customers. read more

If I could give them less than a 1 star I would. They were HORRIBLE from the day they got our down payment. Once payment was made they stopped returning phone calls and emails and when we could get them to answer our calls (usually at every 4th or 5th try) they were nasty, rude, lied about order status, told us to stop calling or it would be another 2-3 months. We were expecting our 4 windows (not a huge order) to take about 8-10 weeks. We placed our order in June 2022. We started to check on them at week 8 for a ship date, then week 10, then 12 then weekly. After 18 weeks and still no ship date - they said by the end of the year sometime - we filed a claim on our VISA card for fraud. Originally VISA said we had a good case but Royal Tech lied on the last week they could respond and said our windows were done and we were not responding to them (NEVER called or emailed us!) and they were just waiting for final payment to ship them. We lost the claim and our $2500 but that's better than the nightmare of getting them and then enduring what some of the other reviews went through with wrong fit or warranty issues! I can't believe they are still in business! RUN AWAY FROM THESE GUYS!! read more

Royal Tech replaced my windows, they did a great job. I am so pleased with my windows and the blinds in between the glass. Love them!!!

DO NOT BUY !! is it possible to give a ZERO rating. They will not stand behind warranty. Purchased Royal tech windows and the windows fogged within 3 years and was informed by Royal Tech Tech that the seals had failed. Had to speak the the owner who was rude and accused me of powerwashing the house without covering the windows and broke the seals ????? Voided the warranty yet the house was never powerwashed. Followed up with the owner of my prior owned house where I had Royal Tech windows installed and 5 years later all the windows had to be replaced due to seal leaks and was given excuses when trying to warranty. They will make any excuse not to warranty their product. read more

They will make up any excuse for reasons why their warranty is not covered. Scam. Read previous reviews, they shouldn't even be in business

After spending over $16,000.00 on new windows, I would NEVER recommend Royal Tech Windows to anyone. I'm still waiting on a copy of the warranty which was never provided at signing of the contact or after the windows were paid off. I have had service come to my home several times already and they still have to return to replace the door wall and several windows. The service tech admitted they weren't built correctly. There is NO quality control at the business and when you call about a problem, Curtis Smith is the only person who will talk to you. Of course none of the issues/problems were his (or employees) fault! Smith is one of the rudest person I have ever had dealing with in my life. He is NOT a man of his word, he is a great talker until he get his money and then he could care less. He will not even come out to look at the windows with HIS name stamped on them! He is an arrogant ass who thinks he knows everything and when I asked about his companies reviews of course he has excuses for every question I had and again, never once took responsibility. Take a tour through his shop and you can just see the unorganized chaos, that's what your purchasing. Like others, I really liked the built-in blinds, now I regret my purchase and hope that everyone does their homework prior to dealing with Curtis Smith! He likes talking about all of his law suits he's been involved in, all I can say is he hasn't dealt with my attorney yet!! If you would like to come and see the quality of windows he sells, please contact me and your more then welcome to come visit my house. DON'T BUY FROM THIS COMPANY or HAVE ANY DEALINGS WITH CURTIS SMITH, ROYAL TECH WINDOWS AKA: NRG Scam!!!! read more

I found the company on line and wanted a window with built in blinds and thought they were a reputable company and found you could buy their windows thru Lowes Homes Improvements which I believed in them more. I am in the process of a new construction and have contracted most of things myself. I ordered the Royal windows thru Lowes on 8/4/2017 and paid $25161.52 in full at that time. I was told they would take 2 1/2 to 3 weeks to get in. After I was in over 4 weeks I started calling Royal tech and each time I had to follow up with several calls before Curtis the owner would give me his rude excuse and a new story of why and how they were behind. After a couple of times of this I got on a few review sites and found his poor rating and he never takes care of his warranty issues. So I called Lowes and tried to cancel order even though I was now over 6 weeks behind on my construction without the windows. I was told Royal had completed the order and they were being shipped so they couldn't cancel the order. I received the windows days later and they were poorly wrapped in plastic and in a wood create and no other packing we took pictures of the scratched finish on the frames and numerous chips and cracks in the frames, The crew started installing the other windows that were not cracked or chipped up because we were now 6 weeks behind. As they put each window we saw the trim that has the poorest fitting edges that don't match up on any of the windows. I also have 4 windows that don't open and close. I called Lowes and they sent 2 guys out and inspected the windows they agreed the were poor quality of windows and they would not be happy at all with the windows if they had purchased them. Lowes is waiting for a refund or adjustment from Royal Tech is what they are telling me and have called their corporate office and Royal Tech will be taken off of business they buy from. I now have $25161.52 in junk windows it looks like I will have to take legal action to get resolution on a refund. Never talked to such a unprofessional business owner as Curtis. read more

We had problems with Royal Tech Vinyl not honoring our warranty. The owner of the company weaseled out of everything, using the most inane reasons. One excuse was that the interior fogging was condensation, therefore not covered. Then it was "we have dashes in our part numbers, and yours doesn't". He contradicted himself by first telling us they have never had 30 year warranties for anything ever, then a few weeks later forgetting that lie and telling us they only had 30 year warranty on a type of window that we didn't purchase. He implied that we were being fraudulent and had printed our own warranty, like "those people in East Detroit". I felt like I needed a shower after talking to him, it was a most unpleasant experience. We ended up paying for replacement windows, because they had failed and we needed them fixed. It was worth the money to not have to deal with him anymore. The installer was very apologetic, and did a great job; it's the owner that is off putting. We still need some windows replaced in the house. I will not be calling Royal Tech. read more
