In 1985 we were broken into soon after we moved into our house. We knew of Doors Unlimited from its' very lively ( and forever imbedded in my brain ,lol ) jingle. We called them and to make a long story short we purchased 2 security storm doors and 1 steel door. They cost more than we wanted to spend compared to other doors on the market but they really had no competitor at the time. Their craftsmanship and caliber of security built into their product seemed worth every penny. Installation of these ""custom"" sized doors was professional & superior. My house is almost 100 yrs old so accomodating the unique sizes was difficult but precise. I am now in the market for an additional security storm door and won't even waste my time shopping around. I can assume that DU has only gotten better or they still wouldn't be in business. The doors originally purchased in 1985 work as well as the day installed but could use a good wash & wax. lol.
