We had our front door replaced in September by glass tec and couldnt be happier
They have been amazing from the beginning and were so patient with my design changes and had great suggestions
The door looks amazing and I couldnt be happier
We had a couple of problems with the lock (no fault of glasstec) but they were great in coming out to assess and then ordered us a new lock and now all is well
Thanks again
