We live in Cape Arundel Cottage Preserve in Arundel, a planned unit development of new homes. We wanted a Mirage retractable screen door. The developer here said use DSI, that they had installed all the doors here in our development. Despite many calls over six weeks, they were not responsive and pretended they never heard of our development. If DSI did not wish to assist us, I wish they would have had the courtesy of telling us that. Later we found out our developer did not renew the contract with DSI for non-responsiveness.

We had a cable snap over the weekend, so that we couldn't open our garage door and had a car inside the garage. Called DSI first thing Monday morning. They diverted a tech to come over within the hour. He quickly replaced all of our cables, adjusted the opener, and performed some routine maintenance. The door opens much easier and is much quieter now. Definitely would recommend DSI for any garage door needs, sales or service.

I backed up into my company's overhead door. After calling two competitors and getting poor customer service, I contacted DSI for help. Not only was Ted extremely helpful and responsive, he was empathetic to my situation and had my replacement panel finished for me in less than 24 hours. If I'm ever in this situation again, I will100% call DSI. I can't say enough positive things about the company and Ted. Thank you.

I can't say enough good things about this company. Both times I called with door issues, they came out the same day. The garage door I have is old, so I just recently upgraded, Ryan installed my new unit. He was professional, competent and very friendly. The front desk staff (Keira and Olivia) are awesome and very helpful too! I highly recommend this company.

Our garage door would not open, and I thought we had a problem with the electric eye units, so I called DSI. They scheduled a visit within one working day. In the meantime, my son-in-law came by, and he said that the problem was actually a broken spring. I did not tell that to DSI, but when they came by they quickly identified the problem as just what my son-in-law had said. I.E., DSI did not perform services that I did not need -- good sign of trustworthiness. They made a temporary fix, then a permanent one later in the day. Courteous, professional (office staff and the tech), highly responsive, and, I think, fair in pricing.

Don't waste your time, I called a couple months back to get my garage door fixed, about 3 weeks went by without hearing anything back from the "salesman" who did a site visit. When I called him to inquire when my appointment for repair was scheduled, I was rudely told to call the service manager on my own. Awful customer service and my garage door still hasn't been fixed. I will be calling someone else to come fix my door.

I have a 9' shop door which was damaged, I called DSI and spoke with Ted, after our intro he wanted to bend over backwards for us. He sent a door tech Alex the same day to ensure my door would work before it could be repaired. My peticular door of course is a discontinued item, but Ted found a section in stock that would work for us & even installed Windows for us so we wouldn't have to replace the entire door, within a day the door was fixed by an outstanding tech named Vladimer who also PM'd, sealed and adjusted the repaired door. Awesome job & second to none service including a great over all price. Thanks big time to team DSI! Ken

We were in the market for new garage doors. The 1st local company I spoke to told me they would have someone call me back.which no one ever called. When I went to DSI they also told me they would have a sales rep call me. Within a few days I was contacted and appointment was made for an estimate. The tech for the estimate was going to be a little late, but he called to let me know.

We did order the doors and everything was done so professionally from follow-up from Ted to let me know status and installation date to the actual installation. We could not be happier with everyone involved and more importantly the look of the new garage doors. What a difference! Thank you Ted and all involved for such great service! I would highly recommend DSI to anyone looking to replace their garage doors.

Garage door was frozen to the floor in this crazy cold weather. The spring broke before the door could break free from the ice on the floor. Googled "garage doors in Portland" and called DSI based on the positive reviews. Talked to Ryan at 11 AM and Ted showed up 3 hours later. Door is as good as new and he was gone in 30 minutes. Both individuals were extremely polite, courteous and professional. Pretty much the epitome of outstanding customer service. Highly recommended if you need some door work done.

My wife and I are absolutely thrilled with the new garage door, with photos attached, that DSI made possible. It absolutely makes the house. We are in great admiration of DSI's pulling off this elegant improvement, which involved a number of talented and friendly professionals across many miles. If there's anything you can't do, we haven't discovered it yet.

Just wanted to tell you that the guy who installed our doors was terrific. He worked a steady 9+ hours without a break and did a great job. A real pro. Please forward this to the powers that be.

I wanted to tell you how much we like the new garage doors. The design is perfect and they're so light weight. The openers are working so much more smoothly. I also wanted to let you know that STEVE, who installed the doors, was very professional. He did a fantastic job! A Big thanks goes to Steve.

A spring on our garage door broke trapping two cars inside. It occurred in the middle of the afternoon. We had a major commitment that evening and needed access to a car. DSI got right on it. Did a temporary fix so we could get to our commitment that night. They made new parts and installed them next morning. It all took less than 24 hours.

I just had my garage door fixed by two amazing young men from DSI-one was Roger, and shamefully, I cannot remember the other's name, but they were both wonderful, efficient and courteous. Roger, suggested that I have a new door installed sooner rather than late. I asked if I needed to get any of the junk removed from the garage, he said they could work around it.

They fixed my garage door after it was hit with a car. It turned out very well and they took care of the repair while I was away on vacation. It was a pleasure dealing with them and I would highly recommend them.
