Stay away from Dennert. Lifetime warranty? Hinge failure. 2/1/2011

I had a garage door installed from Dennert five years ago for approxmately $1200. Recently a hinge failed. Upon closer inspection I noticed that a total of five hinges had already broken. Armed with my paper work/receipt and lifetime warranty I called Dennert regarding this issue. They said that the company Marathon who is the maker of the garage door (Dennert is the installer) is out of business and the "lifetime warranty" no longer applies. However, they will be more than happy to send a repair/technician out for $125 not including parts. Dennert was unwilling to compise on this price even though I had been their customer. So, what can you do if: 1. You are shopping for a garge door, or 2. You already have bought one from them and it starts to fail (there is hope). 1. If you are looking for a garage door company, look elsewhere. When shopping for a door, check the hinges and related hardware, then compare with other companies and hardware stores. Our hinges were the el-cheapies (more on that later). Finally, getting a lifetime warranty is not sufficent. Ask what happens if the company gose out of business. If such an event does occur do they stand behind their work and products? if so, then get that in writing. 2. If you are one of the unlucky ones who bought from Dennert and notice that your hinges are starting to fail, all is not lost and a simple stronger solution awaits. It turns out that Dennert or any garage company will not sell you replacement hinges and parts over the counter, hence the $125 service call (parts not included). The hinges used in our installation have a very small pin and collar, this is a weak link and the cause of the failures. They appear to desigend for a small gate rather than garage door. In essence, a substandard part. I checked the local hardware stores and was wary at first because I noticed that the hinges they sold don't look anything like the ones I have on now, in additon, it comes with carriage bolts, not sheet metal/lag bolts that are currently in place. The reason hardware store versions look different is because they are significantly stronger. The pin and collar is huge by comparion. Nevertheless, the important corresponding holes of the New hinges line up with the old ones. It should be noted that roll-up type garage doors with panels are basically of the same design and a hinge allows the panels to pivot along the tracks. So even though the replacement hinges may not look the same, they perform the same function. I bought five type # 1 hinges at $5- a piece and sure enough they fit. The ones sold at the stores use the aforementioned carriage bolts and nuts, whereas the ones installed at my place use sheet metal/lag bolts. Simply reuse your own screws. The type # 1 hinges also work for the rollers too. At $ 5 per hinge I am going to retrofit the rest of the garage to the way it should have been in the first place. When replaceing the faulty hinges, I simply had the door in the down position and replaced one hinge at a time. No need rasie the door half way or use a c-clamp or broom handle or anything else. The only tool needed was a 7/16 socket and wrench. Double check your work and congratulations you are done, now go have a beer and admire your accomplishment In the end, this is an unfortunate situation and behavior by Dennert. However, when all is said and done you'll have the proper hinges installed and a garage door that will last a lifetime. more

Quickly fixed the broken garage door 1/14/2010

Like these guys! This is the second time I've used them and both jobs were handled quickly and efficiently. They replaced a broken sprint and several guide wheels on the garage door for $325. I write the check, they fix the problem. Pros: Next day service, fixed without me being home Cons: None more

Above and beyond service! 1/1/2009

I called and asked about the charge for $125 and that was the labor charge. Dennert did warranty the parts even though the mfg was out of business. I bought a part that saved my day and the girl dropped it off at my house at no charge since my knee would not allow me to drive! Awesome service, way above and beyond! They change their address the first street address is wrong on this site! Pros: The carriage I bought saved me $250 on a new unit and the girl there diagnosed it for me and told me how to replace the part and save the service call. Cons: I had to wait for her to get off work to deliver it. more


I was charged a 125.00 dollars to replace defective hinges that Dennert put in when they installed the door. To install the hinge, it had self-threading bolts that went into the pannel instead of the bracket. They installed the door 7 years ago. Today they did NOT support their job or their workmanship, the dollar was more important than ethics. They did however get the right hinges that screwed into the bracket instead of the pannel. I would never buy any products from Dennert do to their lack of ethics. Ray from West Hills. Pros: They were on time. Cons: They did not back up their work. more

Great Prices,Variety of products 4/24/2008

Dennert garage door co. offers excellent service and if a customer has any questions they will be glad to answer them. If a customer hears a noise they are not comfortable with, they will send out their sales rep at no charge to advise customer if a service call is needed or just some routine lubrication. They give a 10% discount on some items for cash or check and a 7% discount on some items for credit card. I believe thats what the previous reviewer made a mistake on. Its Illegal to charge extra 3% for c.card and they dont. The previous reviewer just got less of a discount with a c.card. They are a "make the customer happy " kind of company and will follow up any problems that may occur until that goal is reached. more

Avoid this company 5/23/2007

The door did not work when the installer left and they did not want to come out to fix the problem, and still haven't fixed it. They also want to charge 3%for using a credit card more
