Doors in a Day was a really great and comprehensive service! I really liked that fact that they came in ahead of time to laser and measure everything, so when they came to put the doors in themselves, they were able to get all sixteen doors installed in less than three hours. Every door was marked for where it would go, so they didn't have to refit or sand off anything! We had both solid core and hollow core doors installed throughout our house and were just very satisfied with the results! They close and open nicely, and we were even allowed to pick our own hardware! Their customer service was great as well! We've been extremely pleased since the day that they put them in!
