DO NOT USE THIS COMPANY!! We bought our garage doors from there 5 months ago. David installed them. Left a mess all of his trash everywhere. He used mismatching screws. Five months later the whole siding is falling down. After months of trying to g to get them to come out to repair it, he says they are out of business. Debbie the supposed owner does not answer the phone now. David does. He says she sold her phone to him. He said he would pass our number along to her. I asked for her and he said he doesn't have it. So how is he going to pass our number to her? He said he'd find her in the street. WTF?!? Super shady!! read more

I regret using this company to replace my garage door. 5 months ago they replaced my garage door. It has been making a weird noise ever since. I called them a few months ago to come look and fix it. They came out, but the noise continued, but a little quieter and they reassured me everything was as it should be. Every time I opened the garage I had a gut feeling something was wrong. Now it stopped working. I called them, David picked up, he seemed to give me any excuse not to come out, first claiming it was the motor (which we replaced a few years ago, so it is not that old), then claiming the company is OUT OF BUSINESS. My whole experience has been shady with this company. I wish I used a more reputable company initially. read more

Great pricing, great service, and only the best jobs done would highly recommend! Will very much be sharing this service to friends and family in need! read more

Scheduled an in-person estimate and was never informed of any fees. I was then charged $75 after David showed up to give an estimate. Also, I just saw that this company's contractor license 922373 expired on 9/30/24 (this is according to the CA Department of Consumer Affairs Contractors State License Board). read more

they did a great job with my garage door i highly recommend getting service done here

Highly recommend this company! First of all they give free estimates which apparently many companies don't do anymore which surprised me. Larry came out and gave me a free estimate and was very professional and knowledgeable. He and Debbie were very easy to deal with and friendly. I picked out a color and style and type of windows at the top and they came out today and did the job! They arrived on time and were efficient and left my garage tidy. Beautiful door! I always get three estimates for any job and they were the lowest of the three. I'm very satisfied with my new garage door. Everything was thoroughly explained to me as well which I like. Kudos! read more

We had an old screw-model, but working automatic garage door and planned to replace it. Well our garage door spring broke, so it was time. We also have a second manual garage door and wanted a motor for that. I contacted Diamond Garage Doors. They responded quickly (they would've been quicker but I wasn't available). They replaced the broken spring, replaced my old screw motor, installed a motor on my smaller manual garage door, and replaced my old worn out rubber door gaskets along the bottom. It only took them a few hours to accomplish. They did great work! The new openers are super quiet and work great! Their pricing was very fair. I'd recommend giving them a call if ur considering garage door work. Chris and Susan read more

These guys were amazing! My side rails bent which left the door unable to open or close. I called someone right away and they quoted me a price that was $1,600 to fix and these guys came early the next morning and repaired everything for under $300! Amazing! They were recommended by my neighbor and I'll never use anyone else again after their great work, prices, integrity and professionalism. 10 s! Thank you! read more

Twice, they tried to upsell me after they had quoted one price for a new opener for a rental house. I remained firm and they honored the original quote...BUT, they left the first time because there was no AC outlet right next to the opener. There was a hardwire to the original Genie motor. This delay made it more of a problem for my tenants. Other companies said they would plug in an extension cord to test and use, until I could get the power source sorted out. Debbie Dennert (the owner) gave me a reference for a handyman / electrician (Kelly Lane- a long time "friend" of her dad, the original owner of the business) to install an outlet on the ceiling of my breezeway. I got his estimate and sent him over to the rental; he claimed everything was finished when he came to my house for payment......except he would go back the next week to patch stucco. I paid him in cash and set the appointment for Diamond to go and install the new opener a few days later. They called and said the outlet didn't work....but they installed the opener......and they hooked up an extension cord to get it working........ok. When I checked out the electrician's work, nothing worked, no switch controlled the outlet as he initially claimed.......haphazard, loose installation of the electrical box in the attic and stucco gaps all around. Many texts, calls and promises later, no response. When I alerted Debbie about the fact that I was stiffed by her referral, she was dismissive and said she didn't even know him. So I am giving 1 star for the aggravation, delays and uncertainty on whether this referral electrician will ever come to fix the outlet/hole in my ceiling. If he does, I will update this review. read more

Agreed on a proposal and the company tried to raise the price by $800. Found the company to be not reputable and dishonest. Recommend another garage door company. read more

Had these guys come and service our garage door back on April 6th, $215. Less than a month later the door wouldn't open. The guy on the phone went on about the motor not being the correct one, or the rails. Was the spring. Wanted $800 to come and fix it. That's about what we paid for the whole garage door installation in the first place. Not very happy about their service or lack of effort to try and help. Won't be using them ever again. read more

Had Diamond Garage Doors replace the old original 50's hardware and garage door at my house a few weeks ago. Everything from the initial call to receiving an estimate and finally having the door installed was handled extremely well and very professionally, not to mention their price was more than competitive. I would not hesitate to recommend them to anyone who is thinking of replacing their garage door. read more

We ordered the Conejo Deal for a Tune-up and Inspection. Scheduling was super easy and efficient. The technicians arrived on time this morning at 7AM as scheduled. They were in and out in less than fifteen minutes. While the garage door sounds much better now due to the liberal application of lubrication, that was all that was done apart from checking the safety beam. There was no tightening of the hinges, hardware, track, balancing of door, adjustments, or anything else. Now it might be that the door didn't need anything further than just a lube job, but I could've done that work with a four dollar can of non-silicone garage door lubricant from Amazon. So, I'm happy that the door sounds quieter due to the lubrication and am also happy that the safety beam is operational and properly aligned. However, I would have liked a little bit more communication about the rest of the door -- even if that meant it didn't need any of the other aspects of the "tune-up and inspection". Overall, I would contact Diamond Garage Doors again for further service if the expectations are clearly laid out ahead of time -- I know that I will need new seals soon (both on the bottom and around the frame), so hopefully Diamond can handle that! read more

I spoke to Debby and requested a maintenance call for my garage door opener. It was making some "squeaking" sounds that seemed to indicate it needed some tune-up and lubrication. I agreed to the $95 service charge for the job. David and his helper arrived on time. I opened the garage door and they went inside the garage and stood and stared at the tracks and rails for a while. David asked what the problem was and I told him I had called only for a maintenance check and some lubrication of the system. I watched as David's younger helper sprayed some kind of lubricant spray (similar to WD-40?) on the rollers, while David went to the truck to get the bill. He told me the whole maintenance would take less than 15 minutes. David's helper then went inside the garage and asked that I close the door, putting him in the garage and out of sight. I assumed this was so his spray can could reach the rollers. David came with the invoice as his helper re-opened the door. David then went into the garage and pointed out a long, approximately 20"metal rod, sticking out of the motor that was bent in an odd way, like a right angle. He informed me that the opener was broken and needed to be replaced for $475. What? I had never seen that long rod sticking out before that moment! Was I blind? Why had I never noticed such an obvious thing? Also, why didn't he tell me about this first thing when they both walked into the garage and did their initial survey? Who knows? What I do know is that a garage door opener that was working, with some minor squeaks, was now broken and needed to be replaced. When I told David that I wasn't interested in replacing the motor, he told me that I didn't have to repair it today, but when it eventually stopped closing the door, I could fix it then. Thanks. I am also quoting another reviewer here that echoes my thoughts exactly about the value of this service: "There was no tightening of the hinges, hardware, track, balancing of door, adjustments, or anything else. Now it might be that the door didn't need anything further than just a lube job, but I could've done that work with a four dollar can of non-silicone garage door lubricant from Amazon." In other words....I would not use DIAMOND GARAGE DOOR for maintenance work and I will call another provider to repair the current damage. read more

OK, except for the fact they charge for an estimate. To be fair, we knew in advance, but after getting the estimate to repair, we checked elsewhere, received a free estimate, PLUS found out we didnt have to purchase new garage doors or openers. So we went from $2500.00 to $350 read more

So I guess when you need a garage door you tend to shop everyone. At least thats the time I spent when I found myself in need of a new door. Seems everyone I called was either uninterested, too busy, or they felt I was just shopping. So getting a quote seemed really difficult. Thats when I got a hold of Diamond. Super friendly, knew what they were talking about, and the quote was avery reasonable. So once I chose them (no brainer) the instalol and appointment were a breeze. Though I hope I dont have to call for a Garage door again, I wouldnt call anyone else! Thanks Diamond read more

Great service, very professional and knowledgeable. New garage door works beautifully with my old opener. It took them 2 hours, to remove the old door, install the new door and reconnect the opener. They hauled away my old heavy wooden door. I am very happy with the result, and definitely will recommend them. Also the price is right. Thank you all specially David for the great job. read more

What a great experience from start to finish. We were referred to Diamond Garage Doors from a contact on Nextdoor. My door broke on Friday evening and after contacting them on Saturday afternoon, they were able to come out on Monday for the repair. We sent some pics of the garage door and they were able to use the pics to provide a quote over email. The serviceman showed up early, was professional and very considerate. I have a classic car that was trapped in the garage (not running at the moment) and he worked around the car with great care and consideration. The repair was perfect, good communication and service was friendly. I would recommend this service to others in the Simi area. read more

This was the best Garage Door Company I have ever hired! They showed up early, installed a new garage door and were on their way in less than 2 hours. Also, they were better priced than any other competitor. If you need a new garage door or need repairs, this is the only company to hire. read more

Truly a blessing. David came out and installed a new system. Took only 2 hours. :) what really impressed me was that he changed the wiring, replaced the old push button on the wall, and also reinforced the cross beams holding the drive system from the roof of the garage. Really really really impressed with the quality of work, and also his knowledge. Super professional. Will highly recommend them in the future. Paid $325 for the new motor/drive system including labor and parts. Other places wanted to charge me $500-600 to do the same thing. Thank you!!! read more

Quick response, good communication, on time and professionally repaired roll up Garage door. Perfect! Thank you so much Diamond Garage Doors! read more

Good work by Diamond Garage Doors on my house in Woodland Hills. They gave a price far less than another estimate I got. They hauled away the old creaky ugly tilt-up garage door and replaced it with a quieter roll-up from the Unique Garage Doors manufacturer, who offer a wide variety of styles. They used the old opener motor, so I didn't even have to change my remotes or PIN pad. Communication was good, and the delivery and work was quickly done. They even threw in an emergency release when I asked, which wasn't in the catalog. (My garage has no access except that door, so I need to be able to manually open it from the outside.) read more

Spring broke in Garage. I called around their price was in the middle but they said they would be out in 2 hours. Humberto is a garage door master. He replaced the spring and fixed the "sticking" problem I had -fast. read more

These guys are incredible! They not only replaced my door in record time(it was stuck open), they gave me a great deal! Working with Debbie and David was easy and they really made the process easy! Thank you guys for everything! read more

I am very happy with my new garage doors! They gave me a great price (they were $700 less than Costco) and Humberto did a great job installing them. I like that they are a local company, too. Highly recommended. read more

I WILL NOT use these people ever again!! I had an issue with my garage door in 2013, called up Debbie and she set up an appointment to have David come out and replace the motor. Call went well, David did a good job, **** (4-stars). Now let's jump ahead 3 years. Called up Debbie to set up a service call, she sent out David again, he looked at the door and within 2 minutes was able to tell me the door needed to be replaced.... fine. I placed the order for my new door, was told it would be installed about a week later, took the day off to be home, and at 9am I get a call saying "the door didn't come in on the semi truck." Huh?!?! What do you mean it "didn't come on the semi truck," I asked. She stated that the company they order their doors from, Unique Garage Door, messed up the order and the door won't be ready for another WEEK!! When I shared my displeasure of the situation with Debbie, she became silent and didn't seem to care a lot about my position on the matter. I suggested calling someone in MANAGEMENT at "UGD" and finding out what the hell can be done about this before they lose a customer, but Debbie didn't express any real concern for my situation. I actually had to call "UGD" myself!! Fact is, 'Unique Garage Door' is a TERRIBLE company, you can't call to talk to someone of authority, their customer service is beyond terrible, no management available, and they pointed the finger back at Diamond Garage Doors and said Debbie didn't place the order until THIS MORNING, the same day it was to be installed!! GAME OVER!! Mesa Garage Door's, (800)893-1107, will be here TODAY between 12 - 2pm to give me a quote for my new door, and they GUARANTEE they'll beat the price I was given!! I wouldn't use 'Diamond' or 'Unique' if they were the last garage door company left on Earth, ZERO customer service!! read more

Just want to say thanks to Diamond Garage Doors in Simi Valley for their amazing service and prices. You guys rock and I will always try to refer you. Randy read more

One of the best service companies I have dealt with in a long time. My garage door springs broke with my car in the garage for the 3 day weekend. A friend suggested Diamond Garage Doors and I called. Humberto was out within the hour on a late Friday afternoon. He was finished within 45 minutes. Best service ever! Plan to change our garage doors in the future and I will definitely use them. read more

I don't know, but this is the first time I've seen this. Installer Manuel took a picture of my credit card and sent to the billing office instead of just reading off the numbers. When I asked him to delete the picture after he's sent it, he refused and said he can do whatever he wishes with his phone. What kind of a response is that? read more

Arrived promptly and completed replacing the opener in an hour. Clean and professional service. The only negative I can say was I had called a different named company. The installer said it was the same company with a different name. Just made me a bit nervous but it worked out fine. I would certainly recommend and use them. Again. read more

My experience was amazing! Debbie helped me and answered all my questions. She was able to give me an idea of what I needed. The estimate was right on. The installation was quick and efficient. I would recommend these guys to everyone. And if I need any service or a new door at another house, you better believe I'm contacting Diamond Garage Doors again. You won't be disappointed! read more

They quoted me a price over the phone to repair my garage door, the showed up on time, did great work, and charged me exactly what the estimate was. From how well the door operates, I think they did more than just replace the springs - but that is all they charged me for - BEST CONTRACTOR I HAVE EVER USED!!!! read more

I called Diamond Garage Doors for a repair and the service was quick and at a great price. The staff was very friendly and got the job done quickly. I highly recommend Diamond Garage Doors for your garage door needs! read more

I gave them 1 star because when Larry came out he was very thorough in his assessing our doors and measuring for new ones. Unfortunately even after 2 calls to them to follow up, I never heard back. If businesses want to know what to do to fail, don't follow up, don't send a quote. Watch a $3500 sale go to another company. read more
