Not a company to deal with This company basically accused my company if being negligent in installing their product. Nothing could be farther from the truth and they wanted nothing to do with knowing what actually happened. Nor do they apparently have any intention of standing behind their product. We have good reason and cause to believe their product was defective and not safe. Absolutely do not recommend using this company whatsoever

Customer service a disappointment I ordered a glass door in the Spring and received it in unbroken condition in a timely manner. The appearance and quality of the glass was great. Unfortunately my contractor was very off on his estimate and the door wasn't installed until Dec. 2023. The quality of the hanging hardware is almost as good HOWEVER we found that two of four necessary bolts for hanging the door were the wrong size (14mm instead of 13mm) -- no one noticed this on visual inspection as the eye cannot readily discern between 13 and 14. I contacted Otto & Sons because the door could not be installed without these custom bolts. And, as requested I followed up with an email and photos. They NEVER responded despite assuring me that they would get back to me in a day. The other thing I'd say about glass-door.us is that their 3-day period during which one can inspect the door for defects is way, way too short. I cannot recommend this company because of this limitation. No one is likely to install a delivered glass door that quickly! We were lucky … but you may not be as lucky.

Terrible experience Terrible experience! Glass door edge was chipped and on a set of double doors, they were different sizes. No help and simply did not return any phone calls!

Just received and had our glass barn… Just received and had our glass barn door from Otto & Sohn installed today. Great experience overall. The door looks and works great. Omar was very helpful with questions regarding installation . The video from YouTube that he provided was of great assistance to our contractor. Definitely recommending Otto & Sohn.

Excellent customer service Customer services was the best. Mabell ensured my order was complete and delivered as timely as could be expected for a custom order. My first door arrived shattered and Otto & Sohn worked with the delivery company to ship a new door within in a few weeks. From my original order to delivery of the second door was about 9 weeks. One note, I ordered the door with the handle hardware but it didn't allow me to slide the door all the way open or closed so I bought two flat shower door grips from Amazon and they worked perfectly...thank goodness. Thanks Mabell!
